During repairs, after installation, as well as due to the loss of the desired color, partial chips, the batteries must be painted. Often, radiators are repainted, if the color does not suit you, you want to create a single style in the room. The reason for painting can be minor scratches, chips, which often remain after installing the battery.
Before proceeding with staining, you should carefully consider all its nuances. Then a great result is guaranteed. If the question arose “how to paint radiators?”, It is worth considering all the important points of this process.
Preparing Batteries for Painting
A significant role is played by the preparation of radiators for painting. First you need to determine how dirty the battery is, thoroughly clean it. They get rid of dirt with a cloth, brush, an effective spray gun. Even if the radiator is new, it still needs to be degreased, treated with sandpaper, after being cleaned of dust. The paint will crack, partially begin to chip off, quickly lose the integrity of the layer if applied to an unprepared surface.
To perfectly clean the radiators, you need to remove the old layer of paint, completely get rid of the soil. Areas affected by rust need special attention. It is important to process them to metal.
Tools and materials for painting radiators
Of great importance are the tools, compositions used in the preparation of the radiator. A special brush mounted on the drill will provide optimal processing of the battery. Washing solutions also work effectively: it is good to apply them to the entire dry surface of the radiator with a paint brush, and then wrap it with a film. The paint will soften and be removed easily in an hour, you don’t even need to use a drill - a regular spatula is enough. The advantage of special washes is that they are harmless to metal, they only destroy layers of paint.
After there are no traces of the old paint left, the surface must be treated with emery, be sure to degrease. For this, any slightly alkaline solution, white spirit, is suitable. At the final stage of preparation, a layer of anti-corrosion primer is applied to the radiator. After completing all these steps, you can be sure: the surface is ready, the paint will adhere perfectly to it, it will hold securely and for a long time.

Choosing the Perfect Battery Paint
It is important to determine which paint is best for transforming radiators. There are a number of requirements that must be met by paint applied to batteries. At least one hundred degrees heat resistance of the paint is required, abrasion resistance, non-toxicity are also needed, since the batteries are regularly cleaned, and the radiator itself heats up. The paint containing metallic powder instead of coloring pigments differs in the highest heat resistance.
There are special paints for radiators on sale, many use water-based enamels, heat-resistant varnishes. The selected paint must necessarily be designed to cover the metal, match the primer. Good compositions are durable, do not change color, and are able to protect themselves from corrosion.
Glossy gloss, color fastness for a long time are provided with acrylic enamels on organic solvents. But they smell quite strongly upon application. Water-dispersion paints will dry quickly, but it is important to choose them carefully by choosing special types. After painting with alkyd enamels, the uniformity of the coating is guaranteed, it will be durable and resistant to impacts. However, the smell can be observed not only during the painting process, but also some time after drying, standing out from heating.
Color selection
The decision in what color it is better to paint the radiators is up to the owners. Now available a wide range of funds, a variety of compositions. Classical is considered to be white enamel, silver. Some choose colors in accordance with the interior, lighting, general style of the apartment and design features. Gold and bronze shades, subtle patterns, drawings look unusual.
If the look of your old radiators no longer pleases you, then you can try to breathe new life into them with the help of experiments.
- The quality of painting cast iron batteries also largely depends on how well they are prepared. As a tool for applying paint, a smooth foam roller of small diameter is best suited, and a brush is useful in hard-to-reach places. To decide for yourself how to paint the most convenient, you should think about removing the batteries. The radiator separated from the pipes can be covered with a composition on all sides, so there will be much less inaccessible places. At the same time, this method does not always justify itself, sometimes it is easier to paint over the battery more carefully without wasting time removing it. It all depends on the specific circumstances, the shape of the radiator.
- A very important factor is the temperature of the painted surface: the radiator must be cold. To the question “is it possible to paint hot batteries?” any specialist will answer unequivocally: this cannot be done. The most convenient moment is the time when there is no heating season. But the beginning of the heating period will not be a hindrance if you close the valves on the batteries, stopping the access of boiling water. It is enough to wait for them to cool completely to start painting. In the case of applying paint to a hot radiator, it will lie unevenly, swell, and various spots and stains will probably form. Moreover, you can connect the heating only when the paint is completely dry.
WARNING: never paint hot batteries!
- Painting radiators and heating pipes requires care and accuracy. It is good to use brushes, small rollers, spray cans. From the spray gun, it is optimal to process a previously removed battery, then all hard-to-reach areas will be perfectly painted over. It is from those places that are the least accessible that staining should begin. It is important to observe a uniform layer thickness, otherwise the color may subsequently differ in different areas.
- It is recommended to start painting from above, then accidental streaks will not spoil the lower part. You need to cover the entire battery with the composition, not limited to its front part. It is more effective to apply the paint in two thin layers, and wait for the first one to dry completely before re-painting. Then there will be no streaks, and ideal evenness is easier to achieve with thin layers.

Discussion:
Hello, I have a question: all the water pipes in the apartment were replaced, including the risers, as well as the connections to the batteries with black steel. A disabled person lives in the apartment, who does not go outside and, moreover, does not tolerate the smell of paint. We decided to paint all the pipes first with an acrylic-based anti-corrosion primer (because it doesn’t smell) and on top with enamel for radiators also on an acrylic-based odorless “expert”.
But it turned out that all the shops in the city ran around, but such soil was not found. Painted just three coats of enamel. Now I'm thinking, and I'm afraid that this water-based enamel will only destroy the pipes. I think, either you need to quickly clean it off, or leave it, what do you advise? I will order the soil via the Internet, but if it comes, it will not be soon. Which is better: peel off the enamel and let the bare pipes stand waiting for anti-corrosion primer, or leave the enamel until the primer arrives? Will it destroy the pipes - the basis is water?
Margarita, how wrong you asked this question, because the heating season has already begun. Of course there is a way out. Try finding a paint stripper at a hardware store. Another option is troublesome, but if nothing remains: remove the battery and brush it with a brush dressed on a grinder. Moreover, it can be disassembled into ribs if necessary.
Good afternoon! I painted the batteries and now I'm biting my elbows. Maybe you have some advice on how to solve my problem).
4 months ago, I painted the batteries with HAMMER LIGHT 3 in 1 primer-enamel on rust. The paint holds up remarkably, but the persistent chemical smell still lasts! Now they gave heat, the smell is simply suffocating! No airing, no wet towels, no salt, no coffee - nothing can get rid of this “aroma”. It smells even in the vestibule, which infuriates the neighbors on the site. How can I get rid of this paint or smell (except for replacing the radiators themselves)?!
Hello, Elena!
Although it will turn out to be somewhat inconsistent, we will consider each question in turn briefly.
1. Surfaces must be degreased before applying the primer. Before applying the primer, be sure to clean off all the old layers of the coating and the old primer. If you mean a cast iron sewer pipe, then most likely it will also have a layer of resin protective coating on it. It should also be removed down to the metal. Everything is cleaned with sandpaper with a grain of 200. After that, all the dust is wiped off or washed off, and the dried pipe is degreased with white spirit.
2. The paint manufacturer can guarantee reliable adhesion only when using their primers and paints with enamels. However, with regard to water-based acrylic paints, they are all created according to virtually identical recipes, according to the same recommendations. Therefore, it is possible to allow the use of soil from other manufacturers.
3. Given that the enamel will be applied in several layers with a mandatory exposure between layers of 4-6 hours, the color of the primer will be reliably covered with enamel and will not show through. Only if, for the sake of economy, it is decided to apply one layer of enamel, one should also select a primer with the closest possible color or colorless.
4. When using any coating, the most complete operating procedure should be followed. First, all the old coating and primer is removed down to the metal. If rust appears, then it is removed with sandpaper until a metallic sheen appears. The rest of the surface is also lightly cleaned with sandpaper. The main part of dust and dirt is swept or wiped off. With the help of white spirit or other suitable agent, the surface is degreased. After that, you can start puttying to level the surface, if necessary. Then there is division. If puttying was carried out, then the surface should also be primed in order to equalize the property of the entire surface in terms of adhesion. If, however, it is necessary to paint on pure metal, then many varnishes and paints for metal do not involve the application of primer, so that several thin layers of coating can be immediately applied to a degreased surface.
Good luck with the repair!
Hello! I need to paint a cast iron pipe with water based acrylic paint. Please tell me. : 1. Is it necessary to treat the pipe with white spirit before priming. 2. Is it possible to use a primer for metal from another company (I use acrylic enamel for metal and heating radiators “Rainbow”, Novosibirsk)? 3. Should the color of the primer match the color of the enamel? (e.g. the primer is gray and the enamel is white). 4. If the enamel is not water-based, what is the procedure for processing the cast-iron pipe (what for)? Thank you.

How to paint a heating battery? - For those who have old cast-iron "harmonicas", this question worries literally every 2-3 years. Sometimes people think about this, who, during the current repair, suddenly discover that the color scheme of the radiator does not fit into the color concept of the room at all. Every year, on the shelves of construction stores, the range of paint and varnish products increases and it becomes more and more difficult to make the right choice. In this article you will find all the necessary information about what paint to paint radiators on old paint, how to do it, and whether this decision is always the right one.
- It is undesirable to paint modern aluminum and bimetallic batteries. Initially, they are painted at the factory with resistant powder paint, which, thanks to the peculiarities of the technology, lays down perfectly evenly. If you decide that the original color of the radiator (usually white) does not match the interior of the room, and you want to repaint it, then you are unlikely to be able to achieve the same perfectly even coverage. Even if you dismantle the battery and cover it with paint in a horizontal position. In addition, an additional layer of paint will reduce heat transfer, which is a significant disadvantage for regions with severe winters.
- It is undesirable to paint plate radiators, especially those with a large surface area. They are installed in houses where a network with increased internal pressure passes. They have low convection but high heat transfer. As for our question, due to its design, it is difficult to paint a heating radiator of this type with high quality, especially with a brush. If it is really necessary, then you will have to take it off, clean it thoroughly (which is very difficult) and paint it in a horizontal position with an airbrush or spray car paint. But even so, you may not achieve a perfect application. Missing areas may remain in hard-to-reach places, because the elements of the plate radiator are too close to each other.
- Convectors, tubes with fins (especially with frequent aluminum fins) are not painted, because painting can adversely affect their heat transfer. The design of the convector, in addition to the heat source, includes a removable casing. It can be painted to enhance the overall look.
- It is recommended to paint cast iron batteries. This is not difficult to do, the colors are different and they do not affect heat transfer. The choice of color is huge.
- Painting of steel panel radiators is possible. But there is a nuance here - it will not work to evenly cover the surface of the battery with a brush. You will have to use automotive paint in a spray can, and it is advisable to paint in a horizontal position.
Important! In order to bring the battery as close as possible to the desired color and color scheme of the room, it is recommended to use decorative panels. They are sold in hardware stores and online stores. They can be made from wood, metal, plywood, plastic and even glass. These screens come in different shapes, colors and sizes. Figured carving, patterns, photo printing and more can be applied to them. So the choice is great, and you can pick them up for any, even the most sophisticated interior.
- For painting a cast-iron radiator - straight and curved soft brushes, no more than 5 cm wide.
- For painting a panel radiator - a foam roller of small width.
- Paint in cans or spray.
- Paint bath (if the paint is not aerosol).
- Special paint remover (if you decide to get rid of old paint by chemical means) and a metal spatula.
- Drill with a nozzle in the form of a metal brush for stripping the battery from paint residues.
- Solvent.
- Gloves, goggles, respirator or gauze bandage, protective clothing.
- Newspapers, oilcloth, cardboard, masking tape to protect surfaces.
- Rags.
What paints are suitable for painting a radiator?
During the repair process, we think about how to paint the heating battery without smell, without streaks and streaks, so that the paint dries quickly and the beautiful appearance of the device is preserved for a long time. At the moment, there is no such ideal paint yet. However, there are several options for obtaining the optimal result.
For painting the radiator may be suitable:
- water-dispersion and water-based paints;
- alkyd enamel and auto enamel;
- acrylic paint;
- oil;
- silicone-aluminum paint;
- silver.
Let's consider each option in more detail.
Oil paint
Regarding this type of paint, we will immediately make a reservation that theoretically, of course, it is suitable. But in practice, it is almost never used for painting batteries:
- Its biggest disadvantage is that it dries for a very long time. This process can take up to a month, you see, it is not very convenient.
- In addition, oil paint has a rather unpleasant odor.
- It is difficult to paint the surface evenly, without streaks and sagging.
Important! In view of such significant shortcomings, it is recommended to choose another option for these purposes.
Water-dispersion and water-based paints
Water-dispersion paint is made on the basis of polymers and water dispersion. Its main features:
- It is moisture resistant and can be washed.
- Diluted with water.
- Mainly available in white.
The water emulsion is made on a water basis, and it:
- It can have many colors and shades.
- Not so resistant to abrasion, can be slowly washed off when in contact with water.
- Diluted with solvents (eg white spirit).
Important advantages of this type of paints are:
- their environmental friendliness and safety;
- absence of chemical odors during application;
- ease and simplicity of painting;
- the possibility of tinting;
- a wide range of application tools and affordable cost.
Important! The only negative is that the surface must be primed before painting, otherwise the water in the composition will cause rust.
Alkyd enamel and auto enamel
Alkyd enamel is one of the best options for painting a radiator. It behaves well at high temperatures (withstands up to 100 degrees), with temperature extremes, is resistant to abrasion and has many colors.
Regarding its capabilities:
- This type of paint is sold everywhere and is relatively inexpensive. This is the familiar PF-115 and its imported counterparts (manufactured by ACE, Dulux, Sigma Coatings and others).
- A significant disadvantage is the persistent chemical smell, which disappears for a long time after applying this paint to the battery.
- In addition, poor-quality enamel may turn yellow over time.
Auto enamel also has a persistent unpleasant odor, so the room will then have to be ventilated for a long time. There are other nuances of application if you need to paint the heating battery:
- Applying paint from a can is quick and easy, but this, of course, requires skill so that the paint layer lays down evenly.
- With this application, unpainted areas may remain, and it is also necessary to carefully cover all surfaces surrounding the radiator from splashes.
- Auto-enamel has a glossy sheen, it will give out and emphasize all surface irregularities.
Acrylic paint:
- Acrylic paint is also water based.
- It practically does not smell and has an affordable price.
- The basic base is white, but if this color does not suit you, you can tint it in any other shade.
- The temperature limit of acrylic paint is +80 degrees - this is quite enough for average radiators.
- She dries quickly. It takes less than a day to apply 2 coats and it's all dry.
- It does not turn yellow over time, but also requires preliminary priming in order to avoid the appearance of rust.
- After drying, acrylic paint forms a polymer coating that is resistant to washing.
Silicon aluminum paint:
- Perfectly lays down on any surfaces, forming a dense layer which narrows and expands together with metal.
- It withstands temperatures up to 500 degrees, does not require pre-priming, is easy to clean by any means and does not lose its visual appeal for a very long time.
Important! This paint is one of the most expensive. Another disadvantage is the corrosive smell, which disappears for a long time.
Serebryanka
Known since Soviet times. On the shelves of hardware stores are its modern counterparts. For example, heat-resistant paint BT-177.
How is it different:
- It consists of varnish mixed with aluminum powder.
- Silverfish is inexpensive, but also has an unpleasant odor.
Color selection:
- If you just want to update the look of the radiator without significant expenses, then paint it white. White and silver are classics of the genre.
- If you want the batteries to be inconspicuous and fit into the decor, you can paint them to match the walls.
- In a children's room, a radiator can be made part of a fun interior - cover it with bright paint or even make the sections multi-colored. You can apply patterns to the batteries with a brush by hand or using a stencil. It is possible to decorate the radiator with decoupage.
What paint to paint the radiators - you already know, now let's get down to the process itself. It can be divided into two stages:
- preparation (cleaning of old paint);
- applying paint.
cleaning
Ideally, for high-quality cleaning, the radiator must be disconnected and the remaining water drained, since it will be difficult to get from the back side. We will miss how to wash the battery from dust and dirt, everyone will cope with this without additional advice. But there are several ways to clean up old paint.
Method number 1
The simplest and easiest method is to use a special wash. This chemical is sold in all hardware stores. But it is suitable for processing only cast-iron radiators, since cast iron is inert to this substance.
Procedure:
Method number 2
The second cleaning method is carried out using a building hair dryer or a gas burner.
Important! This method is not suitable for cast iron, as the process will take a long time and will be ineffective.
Procedure:
- The essence of the method is to heat the paint layer to high temperatures with the device, and then scrape it off with a spatula or a stiff brush, without waiting for it to cool.
- It is desirable to carry out such work in the open air, therefore, of course, the battery must first be removed. If this is not possible, protect the surrounding surfaces with plywood and open the windows.
Important! This method can damage the gaskets in the radiator, so be prepared for the fact that they will have to be replaced with new ones.
Method number 3
Another thermal method is processing the battery with a fire. The old “old-fashioned” method is laborious, but it allows you to clean the battery not only from the outside, but also from the inside.
Procedure:
- Remove the radiator, unscrew all plugs and other parts.
- Disassemble the battery into sections using a radiator key (the sections are connected by nipples with opposite threads).
Important! If this did not work out immediately, then you can do it after firing.
- Build a good fire in the yard and put a radiator in it. Maintain the fire for about an hour, longer if possible.
- After removing the battery from the fire, clean it with a metal brush, this process will be easy and fast.
- After that, tap each section with a mallet to shake out all the rust accumulated over the years from the internal channels.
- Now it remains to reassemble everything using new rubber gaskets.
Important! Gaskets can be cut out of an unnecessary car inner tube.
- Wipe the radiator from dirt and degrease.
Method number 4
You can also use the mechanical method:
- Put on a drill (grinder) nozzle - a metal brush or an emery wheel.
- Treat the surface of the radiator.
Important! The disadvantage of this method is that it is difficult to reach many places with a tool, so the work will have to be finished manually, using a stiff brush and sandpaper.
- As in the previous methods, the surface should then be cleaned of debris and degreased.
Painting
When asked whether heating radiators can be painted hot, experts answer in the negative, because most paints will not fit well on a hot battery. Painting is best done outside the heating season. If there is no way out already, then paint quickly, without picking up a lot of paint on the brush and then it, shading it with a thin layer. Or shut off the supply of boiling water to the radiator and wait for it to cool, then paint.
Important! During the dyeing process, remember to protect your eyes, hands, and respiratory organs from paint splashes and toxic odors.
After cleaning and degreasing, we proceed to the most important thing - painting. The procedure will depend on the type of dye chosen.
Acrylic and water emulsion
If your choice fell on acrylic or water-based paint, the radiator should be primed with an anti-corrosion compound, otherwise rust will appear over time.
Important! On sale there are paints in which the primer has already been added.
can paint
If you paint the battery with spray paint, then the technology is as follows:
- Start in hard to reach places, and then move on to the front.
- Move from top to bottom in zigzag movements, not stopping in one place, otherwise the layer will lie unevenly.
- It is recommended to cover the surface with two layers, so after the first has dried, proceed to the second.
Important! You can take the radiator to the service station for painting, where specialists will do it professionally.
With the help of a spray gun
Painting with an airbrush takes place in the same way as in the case of spray paint.
Important! To reach all areas, it is better to paint the battery in the removed form.
Liquid solutions
If you paint with paints in liquid form, then protect the surrounding surfaces with oilcloth, as well as newspapers:
- Pour the paint into the paint bath and with a curved brush, first coat all interior and hard-to-reach surfaces.
- After that, with a straight brush, begin to process the front part, moving from top to bottom.
Important! Take a little paint on the brush, the layer should be thin, otherwise streaks will form.
- After the first layer has dried, cover with the second. Two layers are usually sufficient.
Important! Acrylic paint and water-based paint dry quickly and without much odor, you can handle it without problems in a few hours. But alkyd enamel will dry out for more than a day and emit an unpleasant odor for a long time, so we recommend painting the radiator in the summer, when it is possible to open windows for a long time.
That's all the wisdom regarding the choice of paint for the heater and the process of applying the coloring matter. Using the useful information from the article, you can do everything correctly and with minimal losses. You can be sure that by successfully updating the old battery, the interior of the room will improve.

What should be the paint for batteries
A feature of any battery is that in operating mode it always heats up to a high temperature. Of course, the degree of heating depends on the temperature of the coolant and other additional factors. Regardless of whether, along with cast iron, steel or non-ferrous metal, the paint that is planned to be applied to the heating device will also heat up.
And so that the paint for heating radiators does not “please” with an unpleasant odor, harmful substances released into the air, as well as the loss of its solidity, it must:
- withstand high temperatures;
- do not contain toxic substances;
- do not emit an unpleasant odor when heated;
- be resistant to aggressive environments and abrasion.
Types of dyes for batteries
The above requirements are met by many types of paints, or rather individual representatives of these types. After all, most paints are designed for temperatures below +80 ° C. Therefore, manufacturers produce special modifications of their products.
In general, do-it-yourself painting of batteries can be done with the following types of paints:
- acrylic enamels. They are based on organic solvents. This feature causes the release of the smell of the solvent during the application of the acrylic mixture to the battery. However, after drying, this smell becomes history, and a radiator with a pleasant glossy sheen appears in the room. This brilliance lasts for many years.
- Alkyd enamels. They are known for their excellent resistance to wear and high temperatures. The range of colors of these enamels is very large, so many opt for such paints. These dye solutions also give off an unpleasant odor while drying. It can also be felt in cases where the heating radiator heats up very much.
- Water-dispersion paint. Many experts note that such paint for radiators is optimal. This is because it does not upset the nose with a specific smell, and the drying time is very short. True, not every water-based mixture is suitable for batteries. Only the one on the packaging of which there is a corresponding designation is suitable. Its color can be any.
- Oil paints. They were very popular in the past. Known for emitting a solvent odor at the time of drying and a long curing time.
It is worth adding that paint for a radiator may contain elements that resist corrosion and improve adhesion (they are constantly used in primers). Such mixtures have a different color, do not require primers and cleaning the radiator from corrosion.
At least that's what the manufacturers say. In practice, it is better to remove the rust of the heater and use a primer. The processes are long, however, the result is reliable. This is often noted in various videos.
Applying paint to a heating device
It seems that this process is quite simple, but it requires proper execution. Painting radiators includes the following steps:
- Cleaning off old paint.
- Removal of corrosion.
- Degreaser treatment.
- Applying a primer.
- Do-it-yourself application of several layers of dye of a certain color.
The first four points are preparatory.
Features of preparation
There are two ways to remove a layer of old paint:
- Mechanical.
- Chemical.
The first involves the use of a spatula or a round metal brush attached to an electric drill. Working with a spatula requires physical effort, since they need to be moved by their own hands. Moreover, it will take a long time to wash the paint. This must be taken into account in calculating the total staining time. The disadvantage of this option is that it is difficult to reach the bottom of thin slots.
A round metal brush mounted on an electric drill is a more versatile method. It is able to process almost the entire area of the radiator, including many hard-to-reach places. At the same time, the time of work and the physical effort spent will be very small. Most people like this, including those who do the calculation of the repair time and shoot videos of the process.
The chemical method involves the use of special solvents or fatty acids. They process the entire area of \u200b\u200bthe battery and cover the treated surface with a film. Then they rest. The duration of the rest is indicated on the package. It may be different. During it, the paint becomes soft. Of course, it does not slip (and it would be very good), but its removal with a spatula, grinder or wire brush becomes very easy.
It is worth remembering that solvents emit substances harmful to the body. Therefore, when using the chemical method, you need to protect your hands with construction gloves, the airways with a gauze bandage, and even better with a respirator.
The surface of the radiator, cleaned of paint, is treated with sandpaper. They work especially carefully in places where there is corrosion. It needs to be completely removed. Only a pure metallic sheen should remain.
For degreasing use white spirit or any other alkaline solution.
The primer of the radiator is carried out with a solution that meets the following requirements:
- is a product of the same manufacturer that produced the paint. In this case, the primer and paint are best suited to each other;
- contains substances that can resist corrosion.
Features of applying paint
Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply a uniform layer and correct smudges, stains and stains in time. In any case, under the condition of working on hot batteries, the time for applying paint becomes very short. In this case, the mistake made may remain uncorrected. This is often noted in different videos.
True, there are some exceptions. So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly. However, such paints are quite expensive, and the final result of calculating a small repair will be a considerable amount. Therefore, it is better, before painting the radiator in winter, to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the batteries are cold.
If you have to paint a cast-iron heater during the heating season with ordinary paints, then you need to apply a very thin layer of paint. Apply two such layers.
The application of a coloring mixture of a certain color occurs in the following sequence:
- Placing oilcloth or old pieces of newspaper under the radiator.
- Applying paint to the top. Then they gradually go down. Thanks to this, such a problem as smudges is eliminated. First, the coloring mixture is applied to the internal parts of the device, and then to the external ones. You need to paint the entire surface.
- Drying of the first coat of paint.
- Apply the second layer in the same way as the first.
The battery is covered with paint using various tools, namely:
- Brush.
- Airbrush.
- Spray can.
If you plan to use a brush, then you should take several of its options. The first should have soft, straight bristles. The other has curved bristles. Thanks to the second, you can work out with your own hands those places to which access is limited.
In the case of painting with an airbrush, it is better to remove the battery. So excess paint will not get on the walls. In addition, there is a great opportunity to paint the most inaccessible places. Spray painting is very fast. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the treated surface to the spray can should be 30 cm.
How to paint a heating battery: recommendations and photos It is worth immediately clarifying that painting heating radiators is not possible in all cases. First of all, it is advisable to perform this operation for cast-iron radiators, on which a thick and uneven layer of paint not only spoils the exterior of the battery, but also greatly impairs the quality of heat transfer. The second type of batteries that can and should be painted are convectors made in the form of a bent riser pipe with fins pressed onto it.
Painting cast iron radiators If you are the owner of modern models of radiators with aluminum sections, then it is better to refuse the idea of painting. Of course, you can paint it, but you will have to apply many layers of paint, and you are unlikely to achieve the expected effect. The fact is that the battery is painted with a brush, and this method is, by definition, worse than the factory one, so it is better to leave the new battery models alone, and if necessary, cover them with a decorative screen.
How to paint a heating battery: the choice of paint and tools
Brushes for painting radiators Before proceeding to the main stage of work, you need to prepare. First, prepare soft brushes, which should be small in size and of two types - straight and curved. The straight brush is intended for painting external, easily accessible areas, and the curved one is for painting the rear and internal surfaces of the radiator.
Anza flat brush for painting radiators What paint to choose
The main role in this work is played by paint for radiators, which can be of the following types:
- water-dispersion;
- alkyd;
- acrylic;
- oil.
Any paint for heating radiators must be resistant to abrasion, tolerate high temperatures (up to 100 degrees) and not emit toxic compounds when heated. In these parameters, the above options differ significantly from each other. For example, water-dispersion paints do not have an unpleasant odor and dry quickly, but this type of coating is less resistant to abrasion than others, that is, it will have to be updated more often.
Special alkyd enamel VD-AK-1179 for radiators Acrylic paint has a chemical solvent in its composition, therefore, when used, an unpleasant odor is emitted, which takes a long time to weather out of the room. The advantages of such a coating are high abrasion resistance and an attractive glossy appearance.
Alkyd paint for radiators also has an unpleasant odor, but is in high consumer demand due to its high abrasion resistance and a huge range of shades. In addition, the smell from modern building materials is not so pungent.
As for oil paint, it is used less and less as a coating for radiators and pipes. The reason for this is an unpleasant odor, a long drying time and the difficulty in applying an even layer.
How to paint radiators is up to you, but it is best to use alkyd paints from well-known manufacturers. You just need to choose the right color for the cover.

How to paint radiators: preparatory stage
So, the materials are selected. Now you can proceed to the preparatory stage. Old cast iron radiators can have paint chips and many layers on top of them, so you need to completely clean the radiator from the old paintwork to the metal. This operation can be performed using a hot air gun, which melts the old paint with a jet of hot air, after which it can be removed with a spatula.
Cleaning pipes and batteries with a grinder with a special nozzle
If there was no mounting hair dryer at hand, then you can use an alternative option - a flushing solution. This solution is applied to the entire surface of the radiator, after which the heating device is covered with a film. After an hour of action of the cleaning solution, the paint can be removed with a spatula.
The main layer of paint has been removed, now we clean the battery from its remnants with fine emery or a special wire nozzle for a screwdriver. Then we degrease the surface of the radiator with a rag soaked in a special solution, such as white spirit. The final step is to cover the radiator with an anti-corrosion primer, which will protect the radiator from corrosion, but will also improve the adhesion of the paint to the surface.

Painting a heating battery: basic rules
It is immediately worth clarifying that the painting of the batteries should be done with the heating turned off. This limitation is due to the fact that the paint dries very quickly on a hot surface, which can lead to an uneven coating layer and smudges.
How to paint a heating battery after stripping Before painting the radiator, lay an oilcloth or rag under it, which will protect the floors from paint getting on the floor. Start painting the radiator from hard-to-reach parts with a curved brush, and cover the front side with paint at the last moment. This approach will allow you not to smear the newly applied layer of paint, and your hands will remain clean.
Spray painting aluminum radiators In order for the paint for the heating battery to lie evenly, it must be applied in two thin layers. To apply the second layer, you need to wait for the first to dry completely.

Choosing an odorless paint for radiators
The choice of paintwork for the heating system is a rather relevant and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not snap off. But this is its functional and aesthetic load. But the question of what kind of odorless paint for radiators and how to paint them sometimes remains open. An informative excursion into the world of paints and varnishes will help to understand.
Which one is better to choose
The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each of its types has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:
- cast iron;
- bimetal;
- steel;
- aluminum.
For painting heating radiators, the market of manufacturers offers a wide range of species and a rich palette of coatings:
| № | Varieties of coatings | Kinds painted radiators | Advantages | disadvantages | Firm- manufacturer |
| 1 | Oil paint | Cast iron | Wide color palette | Dries for a long time, has a persistent smell, quickly fades, cracks, loses shine | "Tikkurila", etc. |
| 2 | Serebryanka | Cast iron | Excellent high temperature resistance | Persistent odor | "Lacra", "Gloss", etc. |
| 3 | silicate paint | Cast iron | Designed for high temperatures | Long lasting odor | "Nevbytkhim", "Ceresit", etc. |
| 4 | Powder paint | Any kind | Durability, resistance to damage and high temperatures | Coloring in professional cameras | "Triton", "Ral", etc. |
| 5 | Alkyd enamel based on organic solvents | Cast iron, steel, bimetal | Rich range of applications | Characteristic smell, color varies by pigment | "Olecolor", "Enamel", "Tex", etc. |
| 6 | Water based alkyd enamel | Any kind | Barely pronounced odor, no color loss | Titanium white is added to the high-temperature paints of this series, which are not cheap. | "Tex", "Lacra", "Enamel", etc. |
| 7 | Alkyd hammer enamel | Cast iron, steel, bimetal | Hides paint imperfections | There is a faint smell, which disappears after drying | "Olecolor", "Tex", "Enamel", etc. |
| 8 | acrylic enamel | Cast iron, steel, bimetal | Almost no smell, dries quickly, wide range of colors, durability | It is required to carefully prepare the surface to be painted: sand, prime | "Lacra", "Rainbow", "Tex", etc. |
| 9 | Paint in cans | Any kind | Wide range of colors, ease of dyeing process | Strong smell | "Kudo", "Decorix", "Newton", etc. |
Can it be hot dyed?
The opinions of experts on the issue of painting radiators differ: some argue that they need to be painted to protect them from corrosion. Others retort that the application of one or another type of enamel on radiators does not perform any protective function and is purely aesthetic in nature. Another thing is painting pipes in winter when the radiators are hot.
Paints and varnishes suitable for the heating system and withstanding high temperatures require painting on cold batteries. If the radiators are covered with enamel on a hot surface, then the paint will dry “on the fly” and the quality of the coloring will get out of control: sagging and unsightly spots will appear.
It would not be superfluous to recall that when covering a hot radiator, the smell of paint will intensify, and opening windows in winter for ventilation is problematic due to the cold.
Important! Consumers most often choose the white color of the battery coating, but experts say that the dark tone of the radiator color contributes to better heat dissipation.
The painting process
Before proceeding to the stage of applying paint, you need to stock up on the necessary equipment:
- radiator brush (curved, with a long handle);
- regular brush (100 mm wide);
- rubber or silicone gloves;
- respirator (if paintwork is odorous);
- newspaper (to protect the floor from paint stains);
- sanding sheet No. 2 (if necessary, cleaning the batteries from irregularities);
- rag;
- primer;
- dye;
- white spirit (for unexpected skin contact with paint).
Sometimes, the preparatory work takes more time than the staining process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peeled off paint and sanded.
Important! If there is a desire to remove the old coating completely, then you can use a special wash.
- Prime the prepared surface.
- In order to avoid drips, painting starts from the top of the heating system.
- The internal parts of the batteries are also coated first.
- Layers of paint are applied evenly in a thin layer.
- As the paintwork material dries, the radiators are repainted.
Stages of painting a radiator
Technology of painting on old paint
The condition of the paint on the heating system can be different:
- The coating, although old, faded, but has a monolithic adhesion to the base. It is enough to sand the surface a little with sandpaper for reliable adhesion of the next layer of paint.
- The old coating is worn in places, peeled off and metal is visible in places. Here, a more thorough grinding of the surface will be required so that chips and irregularities do not show under the new layer.
- The paintwork is hardened, flaky in large areas, rust shows through in places. Such paint must be mercilessly removed with a metal brush or special preparations for washing. The prepared surface is primed before applying the first layer of paintwork materials.
Important! You can simply update the old paint: apply a fancy pattern to it, after sanding, for better adhesion.
in cans
For the convenience of consumers, paint and varnish manufacturers produce an aerosol coating for radiators. It has excellent properties:
- withstands high temperatures;
- easy and quick to apply;
- dries almost instantly;
- has a pronounced gloss;
- adheres well to any surface.
The only negative is a strong smell, but it will disappear in just an hour.
Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. The movements should be smooth, but fast, in a zigzag pattern. Depending on the quality of the surface of the heating battery, it may be necessary to paint in several layers.
Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because. skill in painting with spray paint will not come immediately.
Having the necessary information about the coatings of radiators, you can get useful tips and learn about the features of the technologies for using paint and varnish products.

An integral role in the arrangement of any living space invariably plays such an important communication as the heating system. The devices that are part of it can not only heat the air in the room, but also be part of the interior, while a well-designed radiator will become a real decoration of any living area.
However, old batteries with peeling paint are unlikely to be able to decorate the house in any way, so the owners find a solution to this problem in replacing old equipment with new ones. This method is quite effective, but also very expensive. Therefore, it will become a much more reasonable solution in terms of savings.
It should be noted that in the process of deciding which paint to paint the radiators with, you should opt for special compositions designed specifically for such structures. Their use will protect the surface of the radiator from the appearance of corrosion on it and provide the unit with an aesthetic appearance. If earlier it was customary to cover the functional parts of the heating exclusively with white compositions, today the materials for painting have a variety of shades, so choosing the option that will best suit the interior of the room being equipped will not be difficult.
What determines the choice of paint for batteries
To figure out which paint is best for painting batteries, it should be remembered that the quality of the composition used directly depends on the final result of the work.
- resistance to high temperatures (at least 100 ° C);
- resistance to aggressive environment;
- wear resistance;
- the absence of any harmful substances emitted.
These include:
- Acrylic based enamels. Their manufacture is carried out using solvents of organic origin, as a result of which, during their drying, a characteristic and not very pleasant smell arises. However, such paints have a glossy sheen that will not disappear even after many years of operation.
- Alkyd type enamels. Such compositions are very resistant to high temperature effects and are wear-resistant. In addition, you can always choose the desired shade, as these paints are available in rich colors. The main drawback of these enamels is an unpleasant smell, which not only persists after several days immediately after painting, but can also appear again when the radiator is heated strongly.
- Water based paints. This option is considered optimal among consumers, since such an odorless battery paint dries very quickly (more details: ""). However, when choosing such a composition, it is very important to pay attention to its packaging, which must contain information about the possibility of applying such paint to the elements of the heating system. High-quality paint for odorless radiators cannot be cheap.
Thus, we can say that the only paint for an odorless battery is water-dispersion, so it is on this material that special attention should be paid.
Oil-based paint is less often used today, as such a composition has outlived its usefulness over time and has given way to more modern paint and varnish products.
Preparation before painting radiators
It is important not only to decide which paint is better to paint the batteries, but also to carefully prepare the desired surface for processing. At the same time, an important fact is that the preparatory activities themselves take much more time than the process itself.The procedure should be as follows:
- The surface of the radiator must be thoroughly cleaned by removing old paint from it and cleaning up places with rust that has appeared. Dust and dirt should also be removed with a cloth.
- Next, you need to apply a solution to the battery that washes off the old coating, and then cover it with a film to soften it. Further, the paint can be easily removed with a construction spatula or a grinder equipped (read: "How and how to remove paint from a radiator - tools for removing old paint before painting a radiator").
- After that, the already cleaned surface is sanded with sandpaper and degreased with any solution with a small amount of alkali.
- A primer with anti-corrosion properties is applied to the already cleaned surface, which not only prevents the appearance of harmful formations, but also increases the adhesive properties of the paint. It is best to use an alkyd primer for these purposes.
Radiator painting process
Having finally decided on what paint to paint the radiators with, all actions should be performed in accordance with the following order:- Initially, you need to protect the floor from contamination by laying it so that paint stains do not fall on it. For these purposes, unnecessary paper (for example, old wallpaper) or fabric is perfect.
- Then you should choose brushes with soft bristles. At the same time, one of them should have a straight shape, and the other should be curved in order to be able to apply paint to the most inaccessible parts of the radiator.
- Apply the coloring composition first at the top of the battery, gradually moving towards its bottom. At the same time, do not forget that you need to paint all areas of the radiator, starting from the inner floors and ending with the outer ones. This is done in this order so as not to accidentally stain your clothes or hands. After the first layer of the composition dries, you need to apply the second. Experienced craftsmen recommend: no matter what paint to paint cast-iron batteries or batteries from another material, it will be much more correct to apply two thin layers than one thick one, since it is in the first case that it will be possible to ensure a uniform coating of paint. See also: "".
By performing all the above steps in exactly this sequence, it will be possible to achieve a perfectly even and smooth surface of the radiator, and the applied paint itself will last a very long time (read also: ""). The main thing is to choose the right composition that will be most suitable for a particular heating battery.
If necessary, you can always study various photo options for coloring these devices in order to best choose the desired color scheme for yourself.
Tips for painting radiators on video:
Mechanical damage, natural wear of the paintwork, repair work and the addition of new elements to the system - all this leads to the fact that the radiators in our homes lose their appearance. It is usually impractical to make a complete replacement of heating devices - this is a very energy-intensive and financially costly process. For a budget update, heating batteries resort to staining.
To ensure that the result does not disappoint, it is important to choose the right paint, and then, before applying a new coating, carefully prepare the surface. Wrong choice of paint, poor-quality preparation, most often ends with the fact that the coating wears out quickly, and the battery needs to be updated again.
Main selection criteria:
- Safety - the absence of hazardous components in the composition of the paint that evaporate when heated.
- Heat resistance - the paint must be resistant to thermal stress (80-90 ° C).
- Resistance to fading and mechanical abrasion determines how long the coating will not require updating.
- Adhesiveness - in other words, the ability of the composition of paintwork materials to adhere strongly to the surface.
- Anti-corrosion properties of the paintwork, i.e. the presence of substances in the composition of the paint that save the radiator from rusting.
Note! A good radiator coating must meet all of these criteria. Only a stable, safe, easy-to-use product can provide not only external attractiveness for a long time, but also keep radiators in working condition.
Before painting, it is important to make sure that the paint composition is specifically designed for painting radiators. The purpose of the paint is noted when marking. But if for some reason this information is missing, you need to choose heat-resistant dyes.
The composition distinguishes: alkyd, oil and water-based paints:
- Oil paints dry for a long time, emit a strong odor during painting and drying, quickly wear off, crack under the influence of high temperatures, poorly protect against corrosion, and they are not recommended for painting batteries. Low price, cannot smooth out all the disadvantages when working with oil paints.
- Water-dispersion paint is safe, low cost and fast drying. However, this type of coating is short-lived and resistant to abrasion, therefore, such a coating will need to be updated quite often. Acrylic paint also belongs to the dyes of this group, which is distinguished by resistance to temperature extremes, strength in relation to mechanical stress. It is durable, retains an attractive appearance for a long time, does not fade for a long time. With the help of acrylic paints, a durable coating is created that has a juicy bright color, resembling plastic with a slightly shiny sheen.
- Alkyd paint is suitable in all respects for use as a coating for radiators: it has a uniform composition and is highly resistant to abrasion. The composition of alkyd paints includes substances that resist corrosion processes. One of the interesting types of alkyd is hammer paint. With its help, a coating is created that distinguishes an uneven surface, resembling chasing in appearance, this allows you to hide irregularities and gives originality. However, the alkyd coating, with all the advantages, has a persistent unpleasant odor that disappears for a long time, and sometimes, with strong heating of the batteries, it appears even after complete drying. The paint dries very slowly and is best used only where there is good ventilation. In addition, the paint does not retain color well, and eventually begins to turn yellow.
Note! When choosing alkyd paints, it is better to prefer a glossy finish, in comparison with a matte one, it is able to retain a color shade and not give yellowness by about 20% longer.
- Among other types of paint and varnish coatings that are suitable for painting radiators are dyes based on silicate resins and aluminum. If we discard the only drawback - a strong pungent odor that they emit during the staining and drying process, then this is one of the most stable types of coatings that have excellent adhesion: no primer is required for painting, since the paint itself provides a strong adhesion of the composition to the surface.
- Serebryanka - a mixture of aluminum powder with varnish - is another type of coating that is often used for painting batteries, it can be applied both to the primer and to the old paint due to its high adhesiveness.
Heating batteries are an inconspicuous element of our house and harmoniously fit into its interior if they are new, shining with fresh paint. But if the batteries are already old, the paint on them is faded and swollen, then in this state they are striking and are unlikely to decorate the house. The problem can be solved by replacing the batteries. But this is expensive and not always justified, so there is another way out - to repaint the batteries. For this purpose, a special paint for heating radiators is used. Its purpose is to protect the surface of the batteries from corrosion, giving them the desired color, as well as a decent appearance. And if earlier pipelines were painted only in white, now they are painted in the color that best suits the design of the room. Our article will discuss how to choose a paint for heating radiators and how to properly paint them.
Rules for choosing the right paint
The final result depends on the correct choice of paint. Here you should take into account the requirements that apply to paint for batteries and heating pipes. This is:
- high heat resistance (not less than 100°С);
- abrasion resistance;
- resistance to aggressive environments;
- lack of toxicity.
Paints specially designed for painting heating batteries are of the following types:
- acrylic enamels. They are produced on organic solvents, so their drying is accompanied by the release of a characteristic smell of the solvent. But the result is a pleasant glossy sheen that lasts for many years.
- Alkyd enamels. The surface painted with such paint is resistant to high temperatures and abrasion. This paint is available in a fairly wide range of colors, it is possible to choose any color you like, so it is very popular among consumers. The disadvantage is also an unpleasant odor, which persists for several days after painting, but can resume at high temperatures.
- Water-dispersion paints. This choice is considered optimal, since these formulations do not have a specific odor and dry much faster. It is only necessary to pay attention to the marking on the packaging: for painting heating batteries and pipelines.
There is also oil paint, but recently it has been little used for this purpose, this option has become obsolete. What paint for radiators is better? Each of them has its pros and cons, so the choice ultimately remains with the consumer.
Paint for heating radiators must be heat-resistant, abrasion-resistant and free of harmful substances
Preparing Batteries for Processing
To achieve high-quality painting of batteries, it is necessary to properly prepare their surface for painting. Preparatory work before painting takes longer than painting itself.
Batteries are prepared for painting in the following order:
- The surface is thoroughly cleaned before painting: the old layer of paint is removed, and the places where rust has appeared are cleaned to a metallic sheen. Dust and dirt are wiped with a wet cloth, and the old paint is removed with a spatula and special solutions for rinsing.
- The washing solution is applied to the surface of the battery and covered with a softening film. After this, the paint is easily removed with a spatula, grinder or a metal brush worn on a drill. In this case, it is advisable to wear construction gloves on your hands and protect the respiratory tract with a respirator or gauze bandage.
- Next, the surface of the battery is sanded with sandpaper, then degreased with white spirit or any slightly alkaline solution.
- An anti-corrosion primer is applied to a well-cleaned surface, which will not only protect it from corrosion, but also increase the adhesion of the paint to the battery surface. For this, an alkyd-based primer is best suited.
The primer must be chosen one that has anti-corrosion properties (this is usually indicated on the bank), otherwise after a while the rust will appear again. On a well-prepared surface, the paint will lie perfectly.
In order for the battery painting to turn out to be of high quality, it is necessary to carefully prepare its surface - wipe off the old paint, remove rust, wash dust and dirt
Modern hardware stores offer a large selection of paints that already contain a primer and a rust converter. They are convenient in that they are applied to heating batteries without preliminary preparation of the base.
Painting process technology
Now let's look at how to paint a radiator in order to achieve a good result. This must be done with the heating turned off, otherwise in some areas the paint will dry too quickly, lie in an uneven layer, smudges will form that look ugly. Of course, there is a special paint on sale that is intended for use on hot radiators, but it can also lie unevenly if the heating is not blocked.
Currently, heating batteries are painted in colors that are most suitable for the overall interior design of the room.
If there is no other way out and you have to paint the heater during the heating period, then you need to at least turn off the hot water supply yourself or contact the housing office workers with this request. The temperature on the radiator in this case will drop significantly.
So, if you have already decided which paint is best for painting radiators, you can proceed directly to the painting process:
- First of all, you need to take care of protecting the floor from contamination with paint stains. To do this, unnecessary paper or cloth is laid under the batteries.
- We choose small brushes with soft bristles, one straight, the other curved, to paint hard-to-reach places.
- Apply paint first at the top of the battery and move towards the bottom. The battery is painted from all sides: first, internal floors, then external ones, in order to avoid staining hands and clothes. After the 1st layer of paint has dried, a second one is applied. You need to remember the rule that two thin layers are better for paint than one thick one. After all, only in the first case will a uniform and smooth paint coating be guaranteed.
The radiator can also be painted with a spray gun or from a spray can.
Painting a heating battery with heat-resistant paint from a spray can is convenient and fast, while the paint lays down in a thin even layer
When using an airbrush, it is recommended to remove the battery so that all hard-to-reach areas can be painted. Coloring with a can filled with heat-resistant paint is carried out very quickly and efficiently. Usually, detailed instructions for painting surfaces with a spray can are given on its packaging. Basic rule: perform zigzag movements from top to bottom at a distance of about 30 cm from the surface to be painted.
Before painting radiators, it is important to study the technology of this process, because its observance will ensure an attractive appearance of the heater and its reliability.
