How to clean a pipe from paint. How to remove old paint from a pipe

When upgrading or repairing a heating system, it is often necessary to improve the appearance of system components. To do this, you can install decorative panels, or change the color of the surface. When choosing the second option, you need to choose a way to remove the old paint from the pipe. It depends on the material of manufacture of the lines, the quality of the paint layer and the availability of tools.

The main condition for choosing one or another method for cleaning the surface of a steel pipe is the preservation of its integrity. This is especially true for the mechanical method, since too much force can lead to a decrease in the wall thickness.

Mechanical restoration

If a small amount of work is planned, a metal brush can be used as the main tool. With its help, a layer of paint is effectively removed even in hard-to-reach places. The disadvantage is that it is very labor intensive. It will take a long time to process the entire surface of the line.

Therefore, power tools are most often used:

Drill. By installing a special nozzle, the outer part of the pipe is processed. In doing so, it is important not to damage the metal surface. Processing of the reverse side of the highway becomes more complicated;
Angle grinder. The use of a grinder is more practical, since its disc has a large enough diameter to remove paint from the mounting units.

Along with the assigned task, mechanical treatment allows cleaning the pipeline from rust. Irregularities are additionally smoothed out. At the end of the work, paint residues are removed with a solvent.

Temperature effect on the paint layer

If, on most of the surface, the protective coating has good contact with the pipe, this connection will need to be partially destroyed. It is best to be exposed to high temperatures. As a result, processing will be greatly simplified.

To do this work, you can use a blowtorch or a hair dryer. Additionally, a spatula is required. By increasing the temperature on the pipe surface, the homogeneous structure of the paint layer is destroyed. Before it cools down - remove with a spatula.

The disadvantage of this method is the possibility of ignition of the protective coating, as well as the release of harmful chemicals. Therefore, protective equipment is necessarily used - a respirator, construction goggles.

Work order:

Shutdown of the heating system.
Cleaning the pipe surface from dirt.
Temperature effect on the lines using a hair dryer or blowtorch.
The paint layer is removed with a spatula.

If necessary, additional mechanical cleaning is carried out using the methods described above. It is forbidden to increase the temperature in those heating areas where rubber gaskets are installed, there are polymer elements. This can damage or change their appearance and properties.

Chemical methods

Paint remover

The least laborious is the use of special chemical compositions. To use them, it is enough to apply the agent to the surface of the pipeline, and then remove the paint layer using sandpaper or rags.

Chemical compositions can be liquid or pasty. The first is required if there are hard-to-reach sections on the highway. Pasty ones are more effective, since they have an increased content of dissolving components.

Features of chemical cleaning of old paint from the surface of heating pipes:

Ventilation in the room where the work is carried out;
Compliance with all safety measures, the use of protective equipment;
Control of the compatibility of the product with the pipe material. After its application, defects should not appear on the surface of the steel structure.

Sandpaper or a chisel are also used to clean up paint residues. At the end of the treatment, the product is removed with gasoline or acetone.

The choice of this or that method depends on the quality of the old coating, as well as the location of the pipelines. Heat treatment is not recommended in residential premises.

Docker S4

A chemical paint remover is applied to the pipe surface with a brush. A good example of such a chemical can be a fairly effective remover of all types of paints without damaging metal and plastic pipes - Docker S4 (manufactured by Docker Chemical GmbH Rus.)

10-15 minutes after applying the DOCKER remover to the pipe, the paint is scraped off with a spatula or a sharp chisel, cleaned, if necessary, with a metal sandpaper, and then the pipe surface is wiped with a cloth soaked in solvent.

Decapant gel express

Universal chemical means for removing paint and varnish coatings include DECAPANT GEL EXPRESS, which can be used to remove obsolete paint, varnish, plaster, mastic, glue (except for two-component coatings) from any type of surface - wood, glass, metal, cement, ceramic tiles ... This gel-like product does not lead to blackening of wood, does not run off when applied to a vertical surface. A 2-3 cm layer of the product is applied with a brush to the surface to be cleaned, kept for a maximum of 30 minutes, the destroyed and softened old coating is removed with a scraper, and the surface is washed with warm water using a hard synthetic brush.

Large metal surface can be cleaned wet sanding: the surface is moistened with water and the obsolete layer is removed with a waterproof sandpaper.

Painting a radiator with a normal paint finish

In the normal state of the paint without visible flaws, if there is only one layer (or two) and they lie flat, you can paint on top without removing the old coating. Only pre-processing is needed.

We paint an aluminum and bimetallic battery

If you want to paint an aluminum or bimetallic battery in which only the color does not suit you, think carefully about whether it is worth spoiling a good coating. Maybe in this case, close the radiator? And one more thing: if the radiators are under warranty, then after painting the factory (or the seller) will refuse warranty repair. Even if the reason is completely different.

If you want to get a color similar to the "factory", contact a specialized service station. They paint cars using the same technology. May they agree to paint your radiators

If you still need to paint an aluminum or bimetallic radiator, it is better to contact a specialized auto repair shop. Only they can professionally help. If you want to do everything yourself, you can use spray paint for cars. But with this option, it is likely that in those places where the radiator is often touched, the top layer will wear off, although it depends on the quality of the car enamel and the starting coating of the radiator.

If you still decide to use auto enamel, you need to work on hot batteries. And the hotter the better. Drying time at 130oC - 20 minutes, at 60oC - 40 minutes, and at 20oC - a month.

An important condition: during work and all the time while the paint dries, the window must be open, the doors to other rooms must be closed. Bring work in mask and gloves

There are a lot of paints in cans, but they need to be sprayed on hot batteries

Everything around will have to be covered with paper, old rags. The can is a good thing, but I almost turned it in the wrong direction, and everything is painted to match the radiators ... During operation, observe the distance that is needed for even spraying - this is about 20-30 cm, but it is written on the package exactly. And in general, even before buying, carefully read the instructions and recommendations for use. So you will understand whether you can provide the required conditions for applying paint.

The order is the same: start with the inner surfaces, then walk the outer surfaces from top to bottom. Don't try to get the perfect color the first time. This is practically unrealistic, especially if the base color is white and some kind of bright shade is applied to it. If you keep the jet in one place for too long, sags and streaks will appear. They are much more difficult to deal with than unpainted areas. It is better to apply one or two more coats after complete drying. The result will be better.

If you keep the jet in one place for a long time, or bring the spray can close, you get such a drop

Change the color of the cast iron

Most often, old-style cast iron batteries need painting. It is definitely better to carry out the work after the end of the heating season: it is safer for you, and the painting will be of better quality. Then the order is:

Completely and thoroughly clean the radiator from dust and dirt. This is done "dry" - with a vacuum cleaner and a brush. If there is dirt that cannot be removed this way, try water and detergent. Grease can be removed well with dishwashing solutions or special acidic agents. This is far from the easiest and most enjoyable process, but if you do not remove the dirt, then there will be bumps and bumps under the paint. Therefore, we cleanse diligently. Let the battery dry.
Then remove the top layer of paint with sandpaper. This is necessary in order to create a rough surface. Only in this way the paint will lie flat. You don't need to brush off the paint completely as long as it is even and free of cracks. Use fine emery paper to roughen the surface, leveling out any minor imperfections if necessary.
Wash off dust with water and let the radiator dry.
Cover everything with a primer compatible with the battery paint of your choice and wait until it dries.

Apply the paint with brushes in several thin layers.

First you need to sand the old paint, then wash off the dust and prime

Painting the panel radiator

There can be two options. If there is a factory sprayed enamel, it is better to use a spray can with auto enamel. If the paint is normal, the procedure is the same as for cast iron. The only difference is that it will be easier to paint the front panel with a roller, and not with brushes.

But in panel radiators, you also need to change the color of the grilles. They will already need to be painted with brushes. If there is rust on the gratings, they should be first cleaned, then treated with a rust converter, primed (with an anti-corrosion effect), and only then painted. All these funds are easiest to buy at the car market - there are many of them in different packaging.

Therefore, power tools are most often used:

Thermal method

This method is based on heating the enamel with a jet from an industrial hair dryer, as a result, the coating will begin to separate from the metal. You can then remove the softened paint with a brush or spatula. But an industrial hair dryer will not always help.

If there are many layers of paint, then it is best to use a blowtorch. It will instantly heat the paint to the boiling point, but be prepared for soot and the release of harmful substances. It is best to remove the battery and start baking it outdoors. When deciding to fire in the house, do not forget about a respirator. Be especially careful when working with open fires indoors.

Mechanical method

This method of cleaning radiators from old paint is the easiest and most effective. The essence of this method is to remove the enamel. To carry out the work, you will need a spatula. Embossed cast iron batteries are easiest to clean using special tools. For example, place a wire brush on the drill. Of course, you will have to wear a respirator and goggles to clean the batteries. The procedure is dusty and rather laborious; dust forms during the cleaning process. But you will finish the job in a few hours.

Before starting the cleaning process, open windows and seal openings that lead to adjacent rooms to prevent dust from spreading throughout the room. Warn your neighbors because the procedure is noisy.

Preparatory activities

Before you clean the pipe of paint by any of the methods considered, go thoroughly to prepare for the repair work. Such preparation resides in the following:

First of all, children, the elderly and animals must be removed from the room in which toxic chemicals will be used, and then ensure the supply of fresh air to this place (to ventilate the room, in most cases, all windows and doors in the apartment are opened) ...
If there are carpets or rugs near the place of work, they are removed and temporarily transferred to another room. Such prudence will not allow the fibers of carpet products to be impregnated with pungent odors of substances, and will exclude the possibility of accidental damage during pipe processing.
In addition, all objects that interfere with it will need to be removed from the work area.
Before starting work with reagents, you need to change into work clothes, and wear protective glasses and a respirator. In the absence of a respirator, it will be possible to use a gauze bandage (mask), which must be changed every thirty minutes.
Then go again to closely examine the site of damage and make sure that the iron base of the pipe is intact and does not lack replacement.

Methods and means of removing paint from metal

Chemical

Aerosols

Commercially available products are universal, as they are designed to soften almost any soil, paint and varnish composition, and some also to remove rust. After about half an hour (± 10 minutes, depending on the manufacturer), the swollen paint mass can be easily removed mechanically. For example, a spatula, knife, chisel.

Price - from 188 rubles / point. (0.5 ml).

Washes

Such funds are called so. Unlike aerosols, they are not sprayed, but applied with a brush. The processing process is longer, but as practice shows, their consumption in the end is much lower.

Price - from 258 rubles / liter.

Solvents

The specific agent is chosen depending on the type of paint. This technique is applicable to remove the old layer only in certain areas, and then if its thickness is insignificant. It is not very effective and is used less often.

Features - any "chemistry" contains toxic components. Before use, you need to take care of protective equipment and provide high-quality ventilation in the room.

Mechanical

The choice of tools and fixtures is limited only by the availability of what is in the house.

El / drill (perforator, "grinder") with a nozzle (). It is advisable to use if it is necessary to remove the paint from the pipe over a fairly large (in length) area.
Brush with metal "bristles".
File with coarse teeth (e.g. rasp).
Emery paper with coarse abrasive fractions.

Thermal

The meaning of such a technological operation is in heating the metal, after which the softened paint and varnish layer is removed mechanically

Basically, a hair dryer (construction) is used for this, less often (with some precautions) - a blowtorch.

Using mechanical methods of cleaning pipes from paint, rust, one should not make significant efforts. The surface treatment "mode" should be gentle. Why? It is visually difficult, especially under a layer of paint and varnish composition, to determine the degree of wear of the metal. Consequently, excessive zeal can lead to cracks, depressurization of joints. The result is the occurrence (maybe even after some time) of leaks and a new, but already more voluminous and complex repair.

Before treating the pipe with any drug, you should securely cover all adjacent surfaces. And not with a newspaper, which is done quite often before painting, but with a waterproof material (better - a rubberized cloth).

Such a safety net will not be superfluous, since it is not known how the "chemistry" will behave in contact with the floor covering, wall decoration, skirting boards (especially if they are made of newfangled plastic).

Radiator cleaning methods

Before proceeding with painting heating devices, it is necessary to remove the previous coating from them. There are several ways to remove old paint from batteries.

Option one - mechanical cleaning. To implement it, you can use:

special brushes for metal work;
angle grinder;
different attachments for an electric drill;
coarse sandpaper.

This method is laborious, it will take a lot of time and patience to implement it, especially for the radiator fins.

Option two - cleaning using chemical reagents. Battery paint remover is usually sold in glass containers. If building washer is used, ventilate the room and use a respirator.

There is a certain sequence of actions on how to remove old paint from a radiator:

a little liquid is poured into a plastic cuvette;
using a brush, the composition is carefully applied to all surfaces of the device;
maintain the period of time specified in the instructions for the composition, most often it is 20 minutes;
when the coating wrinkles and begins to peel off, it is removed from all surfaces of the radiator; a medium-width metal spatula is best suited for this;
the final cleaning is carried out with a metal brush.

One liter of chemical will be sufficient to remove paint from a 10-section battery. To facilitate the work, before removing the paint from the radiator, its surfaces must be thoroughly washed with soapy water and dried.

When the radiator is ribbed, it is more convenient to apply the chemical composition with a spray gun. Before starting work, taking into account the peculiarities of the mixture, objects made of plastic and rubber should be removed from the processing area, and an oilcloth should be laid on top of the floor covering.

To remove paint and primer from one battery, you need about one can of chemical reagent. After about 30 minutes, the coating begins to swell. The paint becomes soft and can be easily cleaned with a metal brush or just a spatula.

Sometimes one time is not enough to remove the old coating and then the procedure must be repeated.

Remove paint from radiator

The way how to remove old paint from the battery is selected individually.

Cleaning and priming the surface of radiators

If the procedure for how to remove paint from cast-iron batteries is clear, and the composition can be removed completely, then it will be difficult to do this from radiators of a new sample with a powder coating.

The smooth polymer surface is an obstacle to good adhesion of old and new paint. In this situation, only one way is possible, how to remove the paint from the battery - it is mechanical cleaning of the surface of the device with sandpaper.

When the gloss is removed and the old coating is cleaned, the entire radiator is degreased with white spirit, nefras or a similar solvent. The subsequent steps depend on the type of paint selected. Enamels made on the basis of heat-resistant varnish or silicone can be applied directly to metal, while alkyd and acrylic compounds need a base to ensure good adhesion of the new coating to the surface.

To extend the service life of newly painted heating equipment, it is necessary to perform a high-quality primer, and the composition for this should be prepared in advance. The most popular brand is GF-021, which is intended for acrylic and alkyd paints. It is usually gray and reddish brown in color.

Battery painting

To paint heating radiators, use brushes, a roller or a spray gun.

You need to act as follows:

Mix the paint thoroughly.
Then it is poured into a small cuvette or other container.
If necessary, the coloring composition is diluted with a solvent of the desired brand. This moment is especially important when working with a spray gun, when a more liquid consistency is required.
When using alkyd enamels and heat-resistant varnishes, white spirit, nefras are used, and acrylic compounds are diluted with plain water.

A roller or brush is immersed in the paint and begins to paint the radiator from top to bottom in two layers.

Method of using chemistry

There are various chemicals for removing old paint in hardware stores. All of them are poisonous, it is required to use a respirator or at least a gauze bandage without fail. You can try to remove the paint with B-52 special agent.

Before proceeding directly to the cleaning process, you need to fulfill a number of requirements:

Clear the room from unnecessary items.
Remove carpets, as the pungent smell of chemicals can be absorbed into them, and you create unnecessary problems for yourself.
Make sure there are no children running around in the room.
Open windows and doors so that the room is constantly ventilated.
Finally, make sure they may need to be replaced.

Apply a chemical solution to the surface. Try to avoid chemical treatment if the paint can be removed mechanically. If, after the mechanical method, some layer still remains, then in this case, chemistry cannot be dispensed with. After applying the chemistry to the surface, you need to wait 10 to 20 minutes, as indicated in the instructions, then remove the remaining paint with a spatula or knife and remove the rest of the product with a rag.

Remove paint with chemicals in a respirator

Is it possible to paint a hot battery

In principle, you can. But then you need to select a paint with a suitable application mode, and they cost twice as much, require compliance with safety measures (respirator and open windows), "smell" much stronger, and are available in a much smaller assortment. So it's a controversial decision.

Can regular paint be applied to a hot battery? This is not recommended. But, as usual, many do so. The smell is then much stronger, but when working with a mask and with an open window, the risk of poisoning is minimal. But that's not all trouble. Some types of paints change color during "hot" application, there is a risk of getting

There are special paints for application to hot surfaces. They can paint a hot battery

yellowish.

The second trouble is that the paint on a hot battery dries very quickly. You cannot come off or be distracted, you need to work intensively with a brush all the time. Still, it will be difficult to achieve an even color. If you only need to "update" the color, it is still possible, but drastically changing it is unrealistic. Wait until the end of the heating season or turn off the battery with ball valves.

There are several types of paints that are desirable to be applied specifically to hot radiators. These are some types of car enamels. Another acrylic enamel "Rainbow" for metal and heating radiators. Here it is desirable to apply it to a hot battery or pipe. Cracks will appear on the cold after drying. But before starting work, read the instructions carefully and follow them exactly. The enamel is good, odorless. If repairs are needed urgently, look for such a suitable color.

Processing features

Building hair dryer

Mechanical cleaning of pipes is reduced, as already noted, to heating the surface with a damaged protective layer and to its subsequent cleaning using a spatula, knife-cutter, metal brush or ordinary sandpaper (the choice of a specific tool depends on the condition of the surface).

Shredder of paints and varnishes

In the case of chemical cleaning, you can use a whole set of special products (solvents and washes), which are widely available on the domestic market these days. The following names deserve special attention:

Solvent B-52, which allows you to remove dyes of various brands. Its use is reduced to the impregnation of a rag with a liquid, followed by wetting the damaged area with paint residues. For better decomposition of the dye, it is recommended to leave the cloth with the reagent in place for 5–10 minutes.
Special cleaners used for both metal and cast iron pipes, most often having an unpleasant, pungent odor. It is to this case that the requirement for mandatory ventilation of the room, as well as the use of a respirator or protective mask, applies.

Note! The wash is applied to the surface to be treated with a brush soaked in reagent for a period of 5 to 30 minutes (depending on the desired result). Before painting, pipes cleaned in this way must be allowed time to dry completely.

Chemical methods

Paint remover

The least laborious is the use of special chemical compositions. To use them, it is enough to apply the agent to the surface of the pipeline, and then remove the paint layer using sandpaper or rags.

Features of chemical cleaning of old paint from the surface of heating pipes:

Ventilation in the room where the work is carried out;
Compliance with all safety measures, the use of protective equipment;
Control of the compatibility of the product with the pipe material. After its application, defects should not appear on the surface of the steel structure.

Sandpaper or a chisel are also used to clean up paint residues. At the end of the treatment, the product is removed with gasoline or acetone.

The choice of this or that method depends on the quality of the old coating, as well as the location of the pipelines. Heat treatment is not recommended in residential premises.

Effective paint stripping techniques

Among the existing methods for removing old paint, the most effective are:

mechanical;
chemical;
thermal.

Each of them has its pros and cons, so it is worthwhile to study all the options in more detail before choosing one or another method.

Preparation for removing paint in different ways, recommendations

It is best to clean cast iron batteries without starting repairs on the street. However, such ideal conditions are not always possible. To carry out the work, you will need a metal staple, gloves, a stiff brush, goggles and rags.

Solvents used must be kept in tightly closed original containers. Damage to the rubber gaskets located at the border of the joints of the sections can lead to leakage of the radiator, so they should not be treated with aggressive compounds.

If mechanical cleaning is performed indoors, fresh air must be provided. With this method, no wash is required.

How to remove paint from a battery

During the repair, among others, you have to decide the question of how to remove the paint from the battery. Cast iron radiators are often used in interior design, especially if they have an unusual look. Therefore, before applying a new coating, it is necessary to remove the layers of old oil paint for many years.

How do I quickly clean my battery?

All known chemical cleaners can be used to clean cast iron radiators. This is the easiest way to remove multiple layers of paint. But among the chemicals there are special means for removing nitro enamels and oil compositions, epoxy or polyurethane varieties. Their use may be ineffective for other types of paints.

Most often, there is no way to find out what exactly the battery is painted with. Therefore, it is necessary to purchase universal preparations that can dissolve several types of enamel. In the recent past, nitro paint and oil enamel were most often used for repair work. Both types are well removed by the AFT remover.

Water-based Paint & Varnish Stripper does not drip from vertical surfaces and is economical. For the treatment of a heating coil of 12 sections, approximately 1 liter of remover is sufficient. It works in 15 minutes.

For work you will need:

chemical remover for paint;
medium flat paint brush.

Before removing the old paint from the radiators, you need to cover the floor and furniture with plastic or newspapers. Safety precautions when working with chemicals provide for a person to have gloves, a respirator, and goggles. It is advisable to open a window in the room.

The wash can be applied with a paint brush, trying to evenly moisten all surfaces of the radiator with the composition. If the liquid is in an aerosol can, then it is sprayed according to the instructions. The composition works for 30-60 minutes. This causes the old paint to swell and soften. It can be removed quite easily with a spatula or knife. Cover the areas that have not been treated with a wash again.

After removing the paint, rinse the radiator with warm soapy water. It is convenient to rinse the inner surfaces of the sections using a household spray. Wipe clean battery with a cloth and dry before painting.

Mechanical cleaning method

This is the most time consuming method. To remove the paint layer, tools with an abrasive surface are used: rasps, files, emery cloth. But the hard layer is not easy to remove in the depressions of the granular and uneven surface of the cast iron.

If the farm has a drill or grinder (angle grinder), then the use of technology can greatly facilitate the task. For these devices, there are special attachments, similar to round brushes made of brass or other metal. Before starting work, it is imperative to wear protective goggles and a respirator, since in the process a lot of harmful dust is formed (when using a grinder) and accidentally flying off sharp fragments of the hardened coating.

Fix the metal brush in the drill chuck or on the grinder. Plug in the tool and clean it, slowly moving along each section, removing the old coating. If the bristles of the nozzle have worn out on hard cast iron before the end of the work, then the brush must be replaced, and then continue the process.

Thermal battery cleaning method

If the radiator is not mounted on the wall, but has already been purchased in a removed form, then the easiest way to clean it is with the help of fire. This will require:

blowtorch (torch, hair dryer);
putty knife;
steel bristle brush;
universal paint thinner.

It is better to work with an assistant, since you will have to almost simultaneously heat the paint and remove it. Protect eyes and respiratory organs with goggles and a respirator, wear gloves. Work is carried out only outdoors, in places that are safe from a fire point of view.

Put the radiator on the floor, light a lamp or burner. Direct a stream of flame at one of the sections and heat the paint until it starts to bubble. Remove the softened layer quickly with a spatula. Continue heating and scraping the coating until the radiator is completely clean.

When the battery cools down, carefully remove the remaining paint with a wire brush. Apply a layer of solvent, wipe the radiator surface. After that, evaluate the quality of the work done. If necessary, the process can be repeated or improved by grinding the surfaces with a grinder.

Batteries that have been cleaned with a fire or a stiff brush are dusty. This plaque must be thoroughly removed before painting using warm soapy water. After removing the dust, the radiator must be dried within 24 hours and then decorated to your liking.

We paint the battery

When painting, an important rule applies: two or three thin layers of paint are better than one thick one. And don't try to paint over perfectly the first time

By using more paint on the brush, you will most likely get a greasy drip, which will not be easy to get rid of. At the same time, it will be no closer to a perfectly native surface than to painting. Therefore, we take a little paint and rub it thoroughly. Even if you can see some metal or old paint. Everyone will fix the subsequent layers.

You will need different brushes for work

First we paint the inner surfaces. A brush with a curved handle can help with this. You may need several of them: from rather thick to the thinnest. Some places can only be accessed with an old toothbrush, so find that too. We start painting from top to bottom from the outermost section. Where is the extreme - to the right or to the left - as it is convenient for someone.

After you have painted everything inside, you start painting the outer surface. The sequence is the same: from one edge to the other, from top to bottom. Why not the other way around? Because when painting from below, drops will fall on the already painted surface, they will again need to be rubbed with a brush. Extra work and time.

After applying the first layer, wait until it is completely dry. Drying times before overcoating are usually indicated on the label. Then apply the second one in the same sequence. Then you decide if you need to paint again.

You need to start painting from the inner surfaces, otherwise you will be painted no worse than the battery

Another point: if after the first layer lay unevenly, there are streaks and irregularities, after drying, take the sandpaper and level them. The second time there will be more experience and everything will turn out better.

How to remove paint from a heating radiator

Hello! If you see that paint is cracked or swollen on your heating radiators, then it will need to be removed. To do this, it will be possible to use different methods.

The easiest and quickest way to remove old paint from a radiator is to use chemicals. Such a tool can be bought at a hardware store. These products are sold in the form of powders, gels and aerosols. You need to buy this or that tool only after you find out what type of paint the radiators were painted with. This is due to the fact that a different chemical is used for each type of paint.

For example, if the heating radiators were painted with oil paint, then it is best to buy an aerosol to remove the paint. It is applied to the surface of the radiator for 15-20 minutes, after which the paint is removed with a dry cloth. In those places where the paint has not been removed, the procedure is repeated

When removing paint with chemicals, it is very important to follow basic safety rules. These rules include the fact that all work is performed only with gloves.

When removing paint chemically, it is best to ventilate the room, as such substances will negatively affect health.

You can also use chemicals that will be water-based. This method of washing consists in applying the remover to the surface of the battery with a regular brush. Before you apply the remover, you will need to cover the floor so that it does not hit the surface. In order for a water-based chemical wash to be sufficient, it will be necessary to correctly calculate the number of sections. The consumption of such a wash must be calculated on the basis that 1 liter of the wash goes into 12 sections.

It will be possible to use a thermal method for removing old paint from the surface of heating radiators. This method of removing old paint involves using a blowtorch or a hot air gun. With these simple tools, paint can be removed. For this, the old layer of paint is well heated and removed with a conventional metal spatula. When you thermally remove the paint, you will need to open the windows, as a rather unpleasant odor will be emitted as the paint heats up.

If you do not have a blowtorch or a construction hair dryer, but you have a grinder, then you can use the mechanical method of removing paint from radiators. To do this, you will need to put on a special circle on the grinder, which will have the same surface as the sandpaper. After that, the surface of the batteries is well processed. And in order to be able to remove the paint between the sections, it is advisable to remove and disassemble the batteries in sections. After the paint is completely removed, you will need to apply 2 to 3 coats of paint to all sections and bond together. After all the sections are fastened together, they can be put back in their original place.

If your finances allow, then you can use an effective way to remove old paint from the surface of radiators, and this way is sandblasting. This method of removing paint will not require expensive equipment from you, but it will require some skills. To remove old paint in this way, you only need a compressor and a nozzle, which is necessary for working with sandblasting. All other work will depend directly on you. The paint can be removed in this way quite quickly and easily, and most importantly, it will not take so much time.

Heating radiators novelty or tradition

All types of heating radiators can be found in modern apartments - from ancient cast-iron batteries to modern high-tech products. All of them can be divided into two groups: convection radiators and radiant heaters. For us, in the context of our interest, their form and the material from which they are made are more important.

Sectional water heating radiators.

As a rule, several such radiators are connected to form batteries. According to the material of manufacture, sectional radiators are of several types.

cast iron radiators;
aluminum sectional radiators;
bimetallic (contain aluminum and steel parts).

Features of the work and the right choice of paint

To change the appearance of a radiator by painting, it is necessary to carry out the following steps:

Choose paint.
Carry out preparatory operations.
Paint the battery.
Dry the paint.

For painting heating devices, heat-resistant compounds are used, made on the basis of:

Acrylic. Compositions with a water base, which includes an acrylic polymer, are odorless and remain bright for a long time. The paint can be given any shade, while the corresponding pigment is added to the base enamel.

Advice: When choosing a coating, its thermal resistance should be taken into account.

Acrylic paint for application on the surface of radiators is designed for heating temperatures up to 80 ° C.

Alcida. In such compositions, organic solvents are the basis, the strength of the coating is higher than acrylic.

Tip: You should not choose alkyd enamel when painting the surface in white or light colors, such coatings turn yellow rather quickly. Alkyd-based compounds can be used to paint batteries, but dark colors need to be selected.

Heat-resistant varnish, where you can add powder from aluminum, bronze.
Silicone resin.

To apply paint to cast iron radiators, in order to give them a more aesthetic appearance, two-component compositions are used in which heat-resistant varnish is mixed with powder having a certain color under:

Gold.
Silver.
Bronze.

Their price is relatively low, the coating is well applied to the product and has sufficient durability. Silicone coatings have the same properties, but enamels are very expensive for their application. The appearance of radiators can be updated by using formulations in aerosol cans with a wide range of colors, and the coating process is significantly accelerated.

Removing multi-layer paint with chemical removers

This method involves the use of aerosols and liquid solvents. Aerosols are considered more effective, allowing you to cope even with hard-to-reach places. They are sprayed evenly over the surface of the radiator. After half an hour, as a result of a chemical reaction, the paint softens and can be easily removed with a metal brush or spatula.

Important! To achieve a good result and effective action of the composition, the temperature in the room must be at least 10 ° C. ... Plate cast iron batteries can be cleaned with a liquid remover

It is applied in a uniform layer to the radiator and kept for 15 minutes. Caked paint is removed with a spatula or metal brush. Before buying a product, read the manufacturer's instructions and find out which coating it can be used for.

The lamellar cast iron batteries can be cleaned with a liquid remover. It is applied in a uniform layer to the radiator and kept for 15 minutes. Caked paint is removed with a spatula or metal brush. Before you buy a product, read the manufacturer's instructions and find out what kind of coating it can be used for.

Heat treatment

The paint emits hazardous substances under the influence of high temperatures, so this procedure should not be performed indoors. If the conditions allow you to cope with a long-term layer of paint, a building hair dryer or blowtorch will help. It is convenient to have an assistant who will quickly remove the heated paint.

Before painting and decorating, the dust layer from the batteries is removed with soapy water. Applying these methods in practice, you will make heating radiators a worthy decoration for your home.

Which is better oil or enamel

Heating radiators operate in difficult thermal conditions. Therefore, the most important factor affecting the durability of the painted surface and its beautiful appearance is the choice of paint.

Requirements for modern paints for heating radiators.

The paint must perform the functions of effectively protecting the surface from moisture, not changing its color and structure under the influence of high temperatures. The factor of mechanical strength is also important. The heating systems of our houses are designed for temperatures up to 80 ° C, so both domestic enamels and paints from foreign manufacturers are quite suitable for work.

What paint to choose .

Enamel PF-115

Frequently used pentaphthalic enamel PF-115 is the best option for price / quality criteria. Good results can be obtained using PF-156, PF-167, PF-187, PF-223, PF-519 paints. The organosilicon enamels KO-168 have also proven themselves to be heat-resistant and abrasion-resistant materials. Alkyd paints and enamels can be successfully used, they successfully cope with temperatures up to 100 degrees and have high mechanical strength. However, they have significant disadvantages such as a strong pungent odor and longer drying times.

But the legendary oil paint, it seems, will soon disappear into oblivion: its color is extremely unstable when exposed to high temperatures.

Variety of materials for coloring

Of the more expensive foreign counterparts, we recommend acrylic and alkyd enamels, designed specifically for painting radiators and hot water pipes. Note that acrylic and acrylate paints and varnishes are practically odorless and have a high drying rate. Today it is the most promising material for the finishing coat of heated surfaces.

Previously, all central heating radiators were painted white. Indeed, it is most invisible in the openings under the windows and is combined with any tone of decoration. Nowadays, pigmentation of paints is being used more and more, due to this they achieve the coincidence of the tone of the painted radiator with the general tone of the decoration of the room.

Tip: if you plan to paint old type cast iron batteries or aluminum radiators with a rough outer surface, choose a matte paint - it will help to effectively hide all defects and irregularities.

How to remove old paint from a battery

Often the question is not how to paint, but how to remove old paint. There are several ways.

Mechanical

You can remove paint from the radiator using a drill and a special nozzle. Another mechanical method includes sandpapering the radiator. But this is a very lengthy process that will take a lot of time and no less effort. If you don't have a drill, you can pay for its rent and remove all layers of paint down to metal in a few hours. Manually, you will have to spend a whole day on this, or maybe more than one - it depends on the size of the battery and the amount of paint on it.

Sandpapering a radiator requires a lot of patience
