How to eliminate condensation on cold water pipes - causes of occurrence, ways to solve the problem. How to eliminate condensation on cold water pipes

Many people are interested in how to eliminate condensation on a cold water pipe. Because this problem is encountered very often.

At first glance, damp pipes for supplying cold water are a source of dampness in the kitchen or bathroom. This phenomenon can also cause mold to appear.

These factors will shorten the period between system repairs during damp room. Why condensation occurs and how to counteract it will be discussed further.

Most often, water supply condensate from cold water appears due to insufficient ventilation in the room. It is for these reasons that moisture collects in droplets in a system transporting cold water.

This is fully aided by moist air. For these reasons, before installing cold water pipe products, it is recommended to create a thermal insulation layer that will prevent any temperature changes on the top of the pipe.

This problem also occurs when the cold and hot water pipes are close together.

If there is such a problem in a bathroom or bathroom, it is recommended to check the functioning of the ventilation at the very beginning.

Behind long time it could get clogged. Problems in the ventilation network are clearly visible when closed windows if there are plastic windows in the room. This can be checked very easily.

ADVICE! If you take a sheet of paper and apply it to the hood with the plastic windows, and then do the same with open windows, then the difference will be visually noticeable. If there is no ventilation, it will be visible immediately.

And one more feature in the bathroom is the layout of pipes with cold and hot water. They are often carried out in close proximity, without laying thermal insulation.

It is not surprising that in the place where water is supplied to the plumbing, the pipes begin to “cry”. On open wiring it is easier to eliminate condensation.

But, in a situation where the network is hidden in the wall, resolving the issue entails more complex work. This will also include repair activities, because the geometry of the structure will most quickly have to be changed.

When considering the causes of condensation in cold water pipes in a bathroom or bathroom, it should be noted that in general the situation is similar to the one described above, but one “BUT” arises.

In these rooms there are an order of magnitude more pipes, and the space, as a rule, is smaller. And here, even at the installation stage, it is necessary to resolve the issue of thermal insulation of pipes.

How to solve this problem

And she deserves special attention. Can be purchased special material, which can be easily purchased at any hardware store for little money.

It doesn’t matter if you don’t have this at hand, you can use improvised means. Polyurethane foam and corrugation can save the situation.

The volume of corrugation should slightly exceed the volume of pipe products laid in the network. The process of action itself is simple to the point of banality.

The corrugation is pre-cut into the required pieces, and they are put on the pipes. The empty space is filled with polyurethane foam. At this point the mission is considered completed.

There is another very simple method that will help eliminate the appearance of water droplets on pipes. To work you need to prepare:

sanding paper;
phosphoric acid;
thick thread;
strips of old fabric;
putty knife;
acetone.

Procedure:

Any pieces of unnecessary fabric are cut into strips no more than 7 cm wide, which are rolled up. It is recommended to prepare them in reserve so as not to be distracted while working.
The pipe is plastered, otherwise the material will not adhere firmly to it. Then it is degreased with acetone.
At this stage, a rust converter is applied, and when the pipes are dry, putty is applied to them. This material hardens instantly, for this reason, you will have to act quickly.
The prepared pipes are wrapped with fabric strips, so that each subsequent turn overlaps the previous one. The final coup is tightly tied with a cord.
Thus, isolation from fabric strips applied in several layers.
The procedure is completed by applying an epoxy layer. When it is completely dry, the pipe products are sanded and paint of the selected shade is applied.

How to get rid of condensation on plastic pipes

A common cause of condensation is leaks in plumbing fixtures. If the workpiece supplying water to sanitary fixtures gets wet, then damage may occur in the faucet, in the shower mixer, in the inlet valve of the toilet tank. A wet riser may indicate that there are leaks in the neighboring apartments above.

If the pipe network is made of plastic, then the problem of how to eliminate condensation on plastic pipes is solved as follows:

The hoods are checked and the ventilation grille is replaced with a compact fan.
The network is insulated using special pipes with a cut. These products are offered in every hardware store. They are made from energyflex and foamed polyethylene. This is a very simple method, only before starting insulation, you need to thoroughly dry the pipes.
Complete insulation of plastic pipes can be ensured by the use of fabric strips and plastering. Above there is detailed description how it is done.

Features of metal water pipeline

The problem of how to eliminate condensation on metal water pipes is no less acute than in previous situations.

If metal water pipes are constantly exposed to drops of water, they will quickly be damaged by corrosion.

Eliminate condensation metal pipes The following actions help rentals:

The pipes are protected from rust, dried and opened with drying oil and oil paint.
Cover with carbonate. This is a paste-like product for sealing cracks in walls and floors; it is applied in a layer of 0.5 cm. This composition should harden for 24 hours, and then the surface is sanded with fine sandpaper and painted with oil paint.
Projector primers. They consist of zinc dust, which is diluted with drying oil. The line is opened with this composition, and then it is painted (with enamel).
The toilet line can be treated with a product based on drying oil and red lead, or with special primers (for example: FL-031, FL-053).

Advice! In the bathroom, the cold water supply line can be painted with any type of enamel, but hot water supply pipes can only be coated with oil-resistant enamels.

How else do you deal with condensation?

Elimination of condensate on pipes is not simple task, without determining the exact cause of this phenomenon.

Experts express this opinion on this matter.

Professional plumbers advise purchasing Corrugated. This is a special composition that can be bought at building materials stores. It is applied to the surface of the pipes and forms a strong and elastic film there, which prevents moisture from appearing.
Experts are also confident in the effectiveness liquid thermal insulation, which is applied to a dry and cleaned highway.
If all plumbing and pipework are in good condition, then condensation can accumulate due to the difference in temperature between the pipes and the air. In this situation, only insulation of the system will help. The most suitable option For such insulation, professionals call foamed polyethylene or Merylon, which are not difficult to buy at any building materials store at a low cost. This insulating material is attached by placing it on the pipeline. Secure it with a clamp and wire.

IMPORTANT! Experts warn that it is possible to eliminate fogging of the water supply system supplying cold water. different methods. Which one to choose can only be decided after a thorough analysis of the situation.

The fact is that in addition to the main ones, there are also side effects that lead to the formation of condensation. The source of dampness is evaporation from the basement, poor waterproofing and insulation of the walls.

Because of this, condensation and frost appear. In such situations, there is only one way out - insulating the floors and walls in the house with high-quality material.

In addition to the reasons already listed that lead to “wet” troubles, there are others. For example, weather conditions. Frequent and prolonged rains, close location of a body of water, proximity groundwater also significantly increases the moisture level in the house.

You can reduce it by installing a moisture absorber or an air conditioner that has a dehumidifying function. Moisture absorbers offered at modern market– an excellent method for removing moisture.

This plastic boxes containing absorbent tablets. When using these devices, they not only get rid of fogging on pipe networks, but also eliminate humidity throughout the entire house.

Experts can advise you on how to eliminate condensation on a cold water pipe. If you entrust them with this task, you can be sure that they will quickly and effectively eliminate the causes that lead to dampness in the apartment. And in this case, you won’t have to worry about people’s health.

If, upon entering the bathroom, you find “dew drops” on the pipes, then it’s time to deal with condensation. Your bathroom is not a greenhouse, and excess moisture there's no point here. High humidity is not a harmless thing at all, and a wet floor under pipes is an unaesthetic sight. Therefore, if you notice condensation on cold water pipes, you need to clearly know what to do.

Causes of condensation on pipes

Most often, the appearance of condensation is influenced by several reasons at once.

Temperature difference

Cold water supply pipes are susceptible to condensation. Due to the temperature difference between the water supplied through the pipes and the air in the room, condensation occurs. This is especially pronounced unpleasant phenomenon happens in winter, when the temperature difference is especially sharp.

Important! It is necessary to clearly distinguish between condensation and leakage. It is not difficult to distinguish them: droplets of condensate are evenly distributed over the entire diameter of the pipe, often along its entire length, while the leakage is local in nature.

Poor ventilation

If the bathroom and toilet do not have forced ventilation, steamed condensation with mold can become their inhabitants. If there is a hood, but the humidity in the bathroom is still high, it means that the ventilation is not doing its job. Check the traction, and if it is weak, contact management company: its workers must check the general ventilation duct and clean it.

Close proximity of cold and hot water risers

When hot and cold water pipes are located too close to each other, condensation will inevitably form. Hiding the pipes under the finish further encourages moisture and aggravates the process. They spoil Decoration Materials, the service life of the entire pipeline is reduced. Considering that all this is hidden from your eyes, the situation is insidious.

Malfunction of the faucet or toilet cistern

A constant supply of cold water into the toilet cistern due to its malfunction or a breakdown of the faucet in the bathroom can also cause condensation on the pipes. In this case, both the tap and the tank “sweat” along with the pipes.

If the shut-off valve in the tank is broken, the water does not fill completely, but flows through and simply does not have time to heat up even a little. The condensate boundary on the tank corresponds to the level of water collected in it. Above the level the tank is completely dry.

The faucet may leak due to wear, malfunction, or improper installation.

Neighbors leak

Sometimes condensation can collect on the cold water pipe only in the upper part. This may indicate that the neighbors above have a problem with their plumbing or a water leak. Here your participation is only indirect - inform your neighbors about this and monitor the results in your apartment. If you remove the leak, the issue of condensation will automatically be closed.

How to get rid of condensation

Depending on the cause of the appearance, the methods for getting rid of condensation differ.

The arsenal of advice from “craftsmen” includes a method of insulating a pipe with cold water by wrapping it with fabric, followed by strict control over its wetting and timely replacement. Sometimes it is advised to add a jar to drain moisture from the ends of the rag into it. Similar method we won't even consider it. This is not a measure, but a half-measure that spoils appearance bathroom or toilet room.

The decision must be serious and thorough, like the owner of the apartment himself. In most cases, the problem is solved by using pipe insulation and good ventilation.

Thermal insulation

To minimize the impact of temperature differences in cold water pipes and room temperature, you need to insulate them. Excellent thermal insulation, high fire safety, ease of installation, tightness and low price modern insulation materials will allow you to appreciate this decision.

The pipe must be covered in a special insulation material - cases made of foamed polyethylene (energoflex). This flexible material, the closed pores of which give it excellent thermal insulation properties.

Your actions:

dry the pipe;
cut the energyflex tube lengthwise;
wrap the pipe with cold water;
fasten the longitudinal seam of the insulation with glue or clamps;
glue the ends of the energy flex together;
If desired, you can paint the insulation spray paint the desired color.

Important! After applying glue to the energyflex tubes, you need to wait 5 minutes and only then glue them together.

Alternatively, Isollat will help prevent condensation from appearing - universal material for pipe insulation, the so-called thermos paint. This is a water-based suspension that, after drying, turns into polymer coating with good thermal insulation properties.

How to paint with Isollat:

clean and degrease the surface of the pipes;
apply paint in one layer with a brush;
To give a glossy shine, the top can be coated with silicone varnish type KO 85.

Creating adequate ventilation

High humidity, and with it condensation on pipes, can be eliminated by establishing good ventilation in the bathroom and toilet.

What to do:

periodically leave the bathroom door ajar to allow fresh air to flow in;
enlarge the opening at the bottom of the door or make a ventilation grill in it;
put powerful fan into the forced ventilation opening;

in case of problems with the common building ventilation riser contact the Housing Office;
include in the future renovation project the installation of windows with micro-ventilation and the expansion of the ventilation hole.

If condensation also forms on the toilet tank, the first step is to check its serviceability. The constant sound of flowing water indicates that the tank is not fully filled and is constantly updated with cold water, which produces condensation.

What can be done:

repair the toilet flush;
buy new toilet with double tank.

A double tank, inside of which there is an additional plastic container, will help completely solve the issue with condensation. Cold water is drawn into it without coming into contact with the walls of the tank, so the appearance of condensation is excluded. The big disadvantage is that the tank is most often sold complete with a toilet and has a fairly high cost.

In a mixer, water control elements most often fail - joysticks, axle-box taps, valves. A thin stream of water leaking around the tap below may be the culprit for the appearance of condensation. Replace the gasket or cartridge and the faucet will be usable again. As a last resort, you can buy a new mixer. Perhaps this will be the end of the search for the causes of condensation.

Don’t put off resolving the condensate issue for too long. And it’s not just about the fact that by sorting it out, you will be doing your health and repairs a great service. Ignoring a problem with unpleasant consequences, while it can be easily and inexpensively solved, is simply unwise.

Many people know how important the thermal insulation of a heating system is - energy losses reduce the efficiency of the system, leading to financial losses. Many people struggle with foggy windows and are looking for a solution. But not everyone knows how important it is to protect cold water pipes. They only think about it when condensing water starts dripping from the pipes onto the floor.

The lack of proper insulation in the case of cold water pipes leads, in some cases, to condensation of water vapor. This forms moisture on the pipes, which falls in the form of drops on the floor and accumulates in the bathrooms. Why condensation forms on cold water pipes, what to do, how to get rid of this phenomenon, we will consider below.

What is condensation?

This phenomenon is due to the condensation of water vapor present in the air on a surface that is colder than the so-called dew point temperature. If the air temperature near the water supply is below the dew point, excess moisture settles in the form of drops on this surface.

The phenomenon of condensation of water vapor from the air is common. For example, when we pour on a hot day cold drink into a glass, dew settling on the walls is a consequence of the phenomenon of condensation. If there are drops of water on the glass - not too much serious problem, and if he sweats plastic pipe, this may cause some problems. Moreover, this problem is more than it seems at first glance - the accumulating water sooner or later begins to drip and the bathroom becomes damp. What to do if cold water pipes sweat, how to get rid of condensation?

Consequences of the problem

In warm weather wet weather Condensation forms on the plumbing in the basement when we turn on the cold water. But excessive condensation can lead to dripping water, which has a number of negative consequences:

It provokes the growth of mold and mildew, the removal of which requires serious costs.
The worst problems occur on pipes made of metal, such as copper or galvanized steel. The accumulation of water on the surface can lead to the destruction of equipment located directly under the water supply.
The walls are damp.

Copper oxidation

Wet insulation can be compared to wet wool on a frosty day. Not only does it not protect equipment from energy loss, but it can lead to corrosion, which often leads to flooding of equipment and premises.

Condensation is technical enemy of insulation No. 1. Introducing water vapor into insulating material outside is also harmful. In both cases, this indicates that the isolation has failed. To make matters worse, condensation in insulation is initially invisible. Over time this can lead to dangerous consequences: Water dripping from the walls or ceiling. If moisture penetrates into the insulation material, its effectiveness quickly decreases.

How to distinguish condensation from a leak?

In some cases, condensation can be confused with water leaking from the system. Check the pipes early in the morning before turning on the water, when the water in the system has warmed up to room temperature. If drops are visible, these may be hidden leaks. It is important to repair hidden leaks before they destroy the ceiling of the neighbors on the lower floor, the walls or floor in the toilet, or provoke the appearance of mold and mildew.

How to deal with condensation?

The main method of preventing water condensation is to create an insulating barrier between the cold surface and environment saturated with water vapor. Only by choosing a coating that meets the following two requirements simultaneously can we protect our installations from undesirable phenomena:

To prevent water vapor from condensing on the surface of the pipe and to increase thermal conductivity throughout its service life, it is important that the insulating material is resistant to moisture absorption.
An important parameter is the low heat transfer coefficient λ, which allows minimizing the exchange of free energy between the pipe and the environment.

How and how to eliminate condensation on a cold water pipe?

Therefore, adequately protecting cold water pipes can help avoid many unpleasant, costly surprises. Modern solutions the problems are quite simple, they can be done with your own hands, without having great skills in the field of plumbing repair. The cost of materials is quite affordable, given the short length of the water supply in an apartment or house.

Thanks to modern technologies Gone are the things of the past: soggy bathrooms and plumbing insulated with unsightly, impractical improvised means, such as a medical bandage or cloth, as people did in the past.

Small droplets of condensate form on cold water and sewer pipes in apartments and private houses all the time. Most often this process can be observed in summer period. Despite the fact that this phenomenon is considered natural and quite natural, it causes a lot of inconvenience to many. We are trying to come up with something, but still, having seen condensation on the cold water pipes, we don’t know what to do. Why are these droplets so harmful?

It would seem that harmless condensation can create significant problems for the owners of an apartment or house:

Accumulating and uniting, drops of water end up on the floor and form whole puddles there, which can even flow to the neighbors below. The floor covering may suffer so much from this that after a couple of years it will have to be replaced.
Harmless drops also greatly reduce the service life of the water supply system, because it is an aggressive environment for metal. Pipes rust, become deformed and after some time will require major repairs.
Condensation on pipes in the toilet, kitchen or bathroom can cause bad smell dampness. But the smell isn't that bad. It is much worse that the consequence of this is the formation of fungus and mold. Bacteria also multiply much more actively in a humid environment, putting people living in an apartment at risk of disease.

Reasons for the formation of droplets

Why does condensation form on pipes? Most often this happens due to the difference in temperature between the surface of the pipes and the air in the room. And if there is no ventilation in the room, or it does not function well enough, then nasty drops will definitely appear. Too humid indoor air also contributes to this. Moisture quickly settles on risers and pipes carrying cold liquid. Every room has its own causes of condensation.

Wet pipes in the toilet

In the toilet, the most common reasons for condensation settling on pipes include:

Condensation in the bathroom

To know how to deal with condensation on pipes in the bathroom, you must first find out the cause of this phenomenon. Some factors are similar to “toilet” ones, but there are also some nuances:

How to get rid of moisture on pipes?

There are several ways to remove condensate from pipes:

Ventilation

Inspect the vent. If you find debris, cobwebs and dust deposits there, you must thoroughly clean it all. After this, it is advisable to purchase special fan, which is installed instead ventilation grille. Plumbing and building materials stores have a lot of such devices from various manufacturers. They can vary in power, price and design.

New tank

In the toilet, the problem of condensation can be solved with the help of a double tank. Inside such a device there is an additional plastic container, into which cold water is collected. The outer walls do not cool too sharply, and therefore are not covered with drops of water. The downside is the high cost of the tank, which is most often sold only as a set together with the toilet.

Natural ventilation

If your bathroom or bathroom does not have supply and exhaust ventilation, organize life in your home so that everyone who takes a shower or bath leaves the bathroom door wide open when leaving the bathroom.

Thermal insulation of pipes

How to get rid of condensation on cold water pipes by thickening the walls? To reduce the temperature difference between the air and the pipe, it is advisable to insulate the pipe. In stores you can find several types of modern insulation materials. They are characterized by high fire safety, high thermal insulation properties, ease of installation, tightness and a completely low price. Special cases made of foamed polyethylene - energyflex - are very popular now. This material is very flexible, so installation should not be a problem. And multiple closed pores will protect very well from temperature “inconsistencies”.

To put the pipe in the energyflex you need to do the following:

dry the pipe thoroughly, after wiping it with a dry cloth;
the energyflex pipe must be cut lengthwise;
starting from one edge, gradually put the insulating material on the entire pipe with cold water;
the longitudinal seam of the energyflex is fastened with clamps or sealed with glue;
if the pipe is long, then, using several pieces of insulation, you need to glue its ends together;
After this, the insulating material, if desired, can be painted with paint from an aerosol can.

Another pipe and foam

How to eliminate condensation on a cold water pipe using improvised materials? If for some reason you cannot buy this modern insulating material, then you can try using a plastic pipe with a slightly larger diameter and polyurethane foam. The plastic pipe is also cut lengthwise and carefully placed on water pipe. Then foam is injected into the annulus. This simple design will last long enough and will not interfere with repair work.

Note: Instead of a plastic pipe, many people use a metal corrugated pipe. You can also run polyurethane foam inside.

Rags

Another option is to use rags (bandages, any other cotton fabric) and epoxy putty. Before you begin insulating the pipe, it must be thoroughly cleaned of rust with sandpaper, and then degreased with acetone and treated with a rust converter. Only after this is the first layer of putty applied, which is immediately “bandaged” with cloth. When this coating has hardened, you need to apply another layer of epoxy.

Isollat and other similar materials

When it comes to thermal insulation of cold water pipes, the universal insulating material “Izollat” helps a lot. This is a thermos paint in the form of a water-based suspension. After drying, the liquid mass hardens and turns into a polymer coating with excellent thermal insulation characteristics.

Painting a pipe with Izollat is very simple:

thoroughly clean with sandpaper and degrease the surface of the pipe;
apply one layer of insulating material;
wait for it to dry;
use silicone varnish for finishing coating and giving a glossy shine to the pipe.

Moisture absorbers

In large construction supermarkets you can find wonderful household devices - moisture absorbers. They will help you deal with the problem quickly and without hassle. Their design is quite simple: an absorbent substance is placed in a plastic box. It will help not only eliminate condensation on the pipes, but also get rid of excessive humidity in the entire room.

Air conditioner

This is the most expensive option, but some people use it too. Installing a climate-controlled air conditioner will ensure a constant optimal level of humidity.

What to do when water condensate remains on the pipes all the time? When you see droplets of water on waterways your apartment, do not ignore the problem in the hope that “it will somehow disappear on its own.” Try one of the above methods and unpleasant consequences can be avoided.

Condensation appearing on the pipeline is a frequent occurrence. This does not make the bathroom more attractive, but rather, on the contrary, it becomes a problem. Damp pipes fail much faster, humidity also increases and mold begins to form. The issue needs to be resolved as quickly as possible. What to do if cold water pipes begin to fog up and condensation begins to form? First of all, do not panic; any problems in the operation of your bathroom must be corrected. You just need to familiarize yourself with the ways to deal with unwanted moisture and get down to business.

Causes of condensation

Residents apartment buildings Often encounter such a phenomenon as a “sweating pipe” with cold water. The reasons for this may vary. The nature of the appearance of water droplets on the pipes in the bathroom and in the toilet is slightly different. In a combined bathroom, the main reasons are:

Often the cause of condensation in the bathroom is poor ventilation.

insufficient;
continuous set;
malfunction (the valve that shuts off the cold water is leaking);
large difference in temperature between water and ambient air in the room;
increased humidity or leakage from neighbors above.

The bathroom should be well ventilated, air circulation allows you to remove unwanted moisture. During continuous operation of the tank filling system, moisture condenses not only on the riser, but also on the wiring. A faucet that drips all the time causes a similar problem.

A broken faucet can also cause increased humidity in the bathroom.

Each of the reasons can independently cause “fogging” of the riser or cold water distribution pipes, but, as a rule, the cause is precisely a combination of several points.

Advice! If the pipes began to humidify suddenly, remember what changes you made in your apartment Lately. The reason may be changing windows or installing any other equipment that increases the temperature of the room.

What are the dangers of a “sweating” pipe?

The condensation that appears on the pipes is not just droplets of water. First of all, it is an aggressive environment for. In conditions of high humidity, the material corrodes and quickly fails.

In conditions of continuous humidification, a damp smell appears in the room. In addition, in places of high humidity, excellent conditions are created for the development various bacteria, including mold and all kinds of fungi. Constant human contact with this kind of “neighbors” is extremely undesirable and can cause disruptions in the body’s functioning.

For metal pipes, constant humidity is fraught with rust.

If the appearance of condensation or its abundance is not detected in a timely manner, puddles may form on the floor. If they are not eliminated in time, then the time for repair work on replacement can be brought closer. flooring In bathroom.

What to do if you notice fogging on pipes

If you notice in the bathroom that the riser or other pipes related to the cold water supply are covered with small drops of water, then you should take a number of actions to find out the reason. Our algorithm will help you:

Important! If all faults in the water supply system have been eliminated, the ventilation is working correctly, then the appearance of moisture is due to the temperature difference.

Installation of new windows or additional systems heating necessarily affects the temperature in the room. If the temperature difference between the water in the pipe and the air in the room is more than 17°C, then condensation will certainly appear.

We get rid of the problem with the help of special devices

If the cause of the “sweating” pipes has been determined to be a temperature difference, then the first need will be to insulate the cold water riser. A variety of materials can serve as insulation; they all differ from each other in price, appearance and degree of insulation.

The simplest option is purchasing foam pads thermal insulation material . They look like soft pipes with a cut along them. The insulation is put on the pipe like a cover and glued together. It is very important not to make a mistake with the size. If you purchase an overlay with a larger diameter, there will be no effect, just like with a smaller size (you cannot glue this one).

Insulating lining for cold water pipes

More expensive, but very effective method– application thermal insulation paint. To insulate a cold water riser, it is necessary to apply 4-6 layers of the substance, allowing each layer to dry completely. When working with paint, it is important to ensure forced ventilation of the room. To do this, you can use a regular fan.

Thermal insulating paint

For greater effect, you can combine the two previous methods. Make sure the coating is completely dry before placing the insulation cover over the painted pipe. It is also possible to apply a layer of paint on top of the heat-insulating nozzle, but only after it is well secured.

Another means of insulation is a larger plastic pipe placed over the main one. The resulting air space is filled with polyurethane foam.

Important! When carrying out any work on pipe insulation, it is necessary to completely dry it in advance from any drops that have formed.

Each of these methods is very effective, but if you did not count on the purchase of expensive coatings, you are better off using the old proven method - creating thermal insulation yourself.

Making your own thermal insulation

Making insulation for a cold water riser yourself is not that difficult. For this we need:

sandpaper;
rust converter (eg phosphoric acid);

Rust remover

strong thread;
cotton fabric (you can use old things);
epoxy putty;
putty knife.

An old sheet or duvet cover works well as insulation. You can use various bandages and other materials. Large and wide canvases are best cut into strips up to 10 cm wide and rolled into rolls.

Epoxy putty

Next, you need to clean the pipe itself and degrease the surface. Can handle it common remedy for removing acetone-based nail polish. The next step is to treat the riser with a rust converting agent.

After careful preparation, insulation can begin. Apply a layer of putty and, without waiting for it to dry, wrap the pipe tightly with a cloth from bottom to top. Wind the fabric so that each turn overlaps the previous one and is saturated with putty. Finally, secure the bandage tightly with thread.

If you notice that condensation often appears on the pipes in the bathroom, do not delay in solving this problem.

Once dry, apply several more layers of insulation. The final step will be to coat the pipe with putty. Once the homemade casing is completely dry and hardened, it can be sanded and painted to match the wall.

Don't leave the problem with high humidity without attention. Not only the appearance of your bathroom, but also the integrity of the cold water supply pipes depends on this.
