How to paint gas pipes outdoors: quickly

Paint selection

The choice of paint composition primarily depends on what material the chimney is made of, because paint for bricks will not be able to fully protect the metal from adverse conditions. Therefore, before purchasing a paint and varnish product, you should carefully read its characteristics and find out what materials it is intended for. But there are also uniform requirements for all paints and varnishes:

Drying time. A very important parameter for outdoor work, because with a long drying time, the applied coating can be damaged by weather conditions.
Temperature range. It is necessary to take into account the approximate temperature of the gases passing through the pipes and the minimum temperature drop in the region.
Conditional viscosity. The optimal indicator would be 36 conventional degrees.
Validity. It is determined how long the protective qualities of the dye are maintained.

If all indicators are selected correctly, then a dense thermal and moisture-resistant film is formed on the pipe surface, which will last for a long time.

Popular paints and varnishes have the following properties:

resistance to degradation caused by oxidation;
resistance to aggressive atmosphere;
low surface tension;
water-repellent ability;
corrosion resistance;
heat resistance.

The maintenance-free service life increases to 15 years thanks to these indicators. It is for this reason that paint and varnish materials are used to protect many objects:

household and industrial heat exchangers;
pipelines with superheated steam;
chimneys;
collectors.

All heat-resistant paints and varnishes in liquid form are highly toxic, and when applying them you must use protective equipment (respirator, gloves and clothing covering the skin).

A good composition for strengthening the surface are organosilicon materials with high moisture-repellent properties, which also have good adhesion to various building materials.

To paint the outside of chimneys, the following coatings are suitable:

The best option for priming the surface is gray enamel KO-8111, which has increased heat resistance.
For bright signal painting, OS-12-03, red and white paints are usually used.

KO-8111 paint perfectly withstands temperatures up to 620 °C, so it is often used when painting pipes of boiler houses and other industrial facilities. It is ideal for external anti-corrosion work on heating and water supply pipelines. This enamel is also used for painting steam lines and other process pipes.

KO-8111 enamel has good moisture resistance and is also resistant to temperature changes. As the temperature increases, the paint applied to the surface even becomes stronger.

For bright signal painting of pipes, red and white paint is applied to the dried, primed surface. This composition is applied in two or three layers, and the paint layer is 35-55 microns thick, with a consumption of 125-160 g/m2 per layer.

Organosilicon paints and varnishes are also considered a suitable material for painting. They have a lot of advantages:

Synthetic polymers have high durability and resistance to damage and abrasion.
The use of this material guarantees increased durability of the coating, since organosilicon paints are unique in their heat resistance. They are able to withstand long-term operation at temperatures up to 720 °C.
This paint and varnish material has low surface tension. It forms a coating that has high weather resistance as well as reduced retention of dust and dirt.

These materials are used to paint:

car mufflers, various engine parts and even jet engine nozzles;
heat exchangers, manifolds and pipelines;
metal and brick pipes of stoves in houses, saunas.

Once the silicone paint dries, it forms a very durable coating. It is fire resistant and has many other protective properties.

Now there is an abundance of silicone paints and enamels for metal and brick pipes

When choosing coatings, it is important to understand their protective capabilities

Types of paints for batteries

Today, many manufacturing companies offer a fairly wide range of products such as odorless paint for radiators. Thanks to this, buyers have the opportunity to choose the most suitable type for themselves:

Acrylic enamel;
Alkyd enamel;
Oil enamel;
Water based.

All types differ from each other in production technology, composition and characteristics.

Acrylic enamel

Acrylic paints:

have no characteristic odor and are excellent for interior work.
Their widespread use in everyday life is also due to the fact that they dry quickly enough,
are characterized by increased moisture resistance,
uniform application on any surface,
and are also absolutely safe for people.
Due to the fact that the substance contains special additives, the paint layer does not begin to crack and turn yellow when the temperature of the radiator or battery increases.
In addition, it should be noted that manufacturers offer a huge range of colors, so acrylic paint for heating radiators is often used in the artistic design of surfaces.

As for the disadvantages, the most significant of them is the high cost. However, it fully corresponds to the good performance qualities of the paint.

Alkyd enamel

Alkyd paints, manufactured using the latest technologies, have the following advantages:

A surface coated with a layer of such a substance is resistant to elevated temperatures - it does not crack when heated to 120C;
High strength;
Homogeneous layer structure during application;
Good resistance to abrasion when operating radiators and radiators;
A wide range of colors allows you to choose almost any color;
The layer maintains its integrity for a long time.

However, in addition to the advantages, there is also a disadvantage - for several days after painting, an unpleasant odor persists, which may subsequently appear if the heating is strong enough. In addition, some brands sometimes fade a little and may also change shade.

Water based enamel

Odorless, water-dispersion paint for hot radiators is an excellent option for coating radiators. It differs from other types in a number of features:

It is made from ordinary water, so it is absolutely safe for people and the environment;
Special dispersed particles are not harmful;
There is no unpleasant odor;
It takes very little time to dry completely;
Apply easily and evenly;
Thanks to the water-repellent effect, painted batteries can be washed without destroying the layer;
Suitable for use in a wide variety of spaces.

The disadvantage is that the color range is not very diverse, because it is mostly only white.

Oil enamel

Oil products are in quite high demand due to a number of their advantages:

No sharp and unpleasant odor after application and further heating of batteries and radiators;
They are divided into colored and colorless;
Easy to apply to metal surfaces;
Form a uniform layer;
Excellent for use inside both residential and non-residential premises;
Low cost compared to other types of battery paints;
Can be used for artistic decoration of surfaces - applying patterns and complex designs.

The downside is that it takes a very long time to dry completely. This is due to the fact that a solvent is added to the paint.

Rules for painting outside and inside the apartment

GOST 14202-69 defines exactly what color and with what identification marks a pipeline for any purpose should be painted. Thus, both the team arriving for repairs and people living nearby can immediately determine which communications have been damaged and what danger they pose.

Gas pipes are designed to transmit different gases and are marked accordingly:

the natural gas pipeline is painted yellow without additional rings;
pipes for acetylene transmission are painted white;
oxygen supply products are blue;
compressed air is indicated in deep blue;
carbon dioxide transfer is indicated in orange.

Painting of a gas pipe running along the facade of a building and on the street is rarely done along its entire length. Firstly, the highways are too long, and secondly, multi-colored segments spoil the appearance of the facade. As a rule, individual areas are painted in order to designate the system.

It is recommended to paint metal gas ducts on the façade of a building in colors that reduce the thermal effect of sunlight.

Identification staining is used in certain areas: at junctions during branching. Painting gas pipes on the facade of a house that pass through a wall must include an appropriate color marker. Painting a pipe passing through a wall.

Inside a building or home, gas pipes are painted in accordance with the requirements of the interior. As a rule, the basic coloring of linear meters of a gas pipeline is white. A gas pipe passing through a wall is not specially marked. Painting services are provided by the builders themselves.

What color should you paint gas lines?

According to GOST, gas pipeline pipes are covered with 2 layers of yellow paint, while painting the valves blue is allowed.

Gas systems installed on the facade camouflage them with the color scheme of the building. Inside the premises, the appearance of communications is brought into line with the style of the interior. Standard painting involves the use of a white solution.

Painting pipes in an apartment yourself - quickly and easily

3 Painting gas pipes

It is impossible to imagine modern residential buildings and industrial structures without all kinds of communications: water pipes, gas pipelines, cables, and so on. Currently, many pipelines (for example, cold and hot water supply) are made of plastic. However, metal pipes continue to be used. To increase service life and improve appearance, these pipelines need to be painted.

As a rule, the reasons for deciding to paint pipes are:

Unsatisfactory condition of the pipe surface.
Corrosion protection.
Improving the interior of the room.

Preparation

The choice of painting method and type of paint depends on the material from which the pipes are made, as well as on their operating conditions. For example, communications located in the open air should be painted with red lead, due to which a mask of iron oxide and lead is formed on the surface. This mask is able to protect pipelines from the destructive effects of the environment.

The following products are usually used for painting pipelines:

alkyd enamel;
water-dispersion paint;
acrylic enamel;
Oil paint.

Acrylic enamel is resistant to high temperatures (up to 1000 degrees). It is also resistant to significant temperature changes. The advantages of water-dispersion paint are fast drying speed, high quality of adhesion to the surface and environmental friendliness. Pipes painted with water-dispersion paint can be used for many years. Such paint, in turn, is divided into two types: for cold and hot surfaces. That is, painting heating pipes will require the use of paint intended for hot surfaces.

Acrylic enamel has the ability to retain color for quite a long time (it is resistant to ultraviolet rays). In addition, this paint makes the surface glossy. Before using this type of paint, the surface must be treated with a primer. And finally, oil paint is suitable for processing almost all types of pipes. However, over time, the original color is lost.

For example, to paint a rusty metal pipe, it is best to use paints from the enamel group. Within a day, the painted surface will be dry. This paint will protect the pipe from corrosion for 7 years. For plastic pipes, the best option would be water-based or oil-based paint.

For painting we will need the following:

brush;
dye;
sandpaper;
gloves;
rag;
primer;
cuvette;
ladder (when working at height).

Before you start painting, it is advisable to clean the surface of the pipes from old paint. After this, you need to thoroughly clean the surface with sandpaper. There should be no rust. All cracks and irregularities must be repaired using putty. Before painting plastic pipes, they need to be washed with warm water. After this, you need to give them time to dry.

The old paint does not need to be removed if the surface of the pipe has no defects: damage, bulges, cracks. Otherwise, it is better to remove the old layer of paint.

Now we determine how much paint is needed. Here are some recommendations on this matter:

For hard to reach places you will need more paint.
The first coat requires more paint than the second.
A smooth surface will require less paint than a rough surface of the same area.

Painting

Before painting, it is recommended to protect the floor under the pipes with film or newspapers. We start painting from the top of the pipes and move towards the bottom. This way the layer will be even. We apply the first layer of paint to the entire surface - do not miss anything. Only after applying the first layer to the entire surface can the second be applied. Applying two layers allows you to get a perfectly painted, smooth surface.

How to quickly paint pipes? To save time, you can use a spray can or spray gun. In addition to saving time, this will give us a high-quality painted, smooth surface. When working with a spray can, you need to hold it at a distance of 30 cm from the surface and make zigzag movements from top to bottom. When using a spray gun to paint the battery, it is recommended to remove it in order to properly treat all hard-to-reach places.

After painting, you need to wait a certain time for the paint to dry and thoroughly ventilate the room.

Types of paint for pipes

The pipe can be painted with anything. For example, the same painting of a cold water riser is done with oil paint, nitro enamel, water-based emulsion, and any other medium. Only if you choose “any other environment”, then the effect of painting the pipe can be anything: positive, neutral, or negative. Therefore, pipes are painted only with the right paints. Which paint will be “correct” depends on the specific pipe and specific operating conditions.

For external pipelines, red lead is the best option. This paint oxidizes the outer metal layer of the pipe, forming a hard film of lead-iron oxide. Such a film prevents further oxidation of steel both under the influence of the atmosphere and under the influence of water.

The enamel group of coloring media is not the worst option for pipe paint.

The average service life of an enamel coating is 5-8 years. Well, if you increase the number of layers, the service life of the painted surface will increase significantly. Moreover, the paint consumption for each layer will only decrease - the surface painted with emulsion no longer absorbs paint.

Internal surfaces are treated with paints with slightly different physical and chemical properties. 100-degree temperature changes in the room are out of the question. Direct exposure to water is also rare.

Therefore, the main option for pipes inside the house is oil paint or water emulsion.

The latter option is attractive due to its complete absence of odor. After all, water emulsion involves dissolving the coloring pigment in water, and not in acetone or drying oil. And the source of the stupefying smell of paint is the solvent.

Painting hot surfaces

For painting hot surfaces, only oil paint is ideal. It tolerates fairly high temperatures. When heated above 250-300 degrees Celsius, oil paint turns into real armor, covering the entire surface of the pipe with a durable crust.

In addition, on hot surfaces, oil paint can last for 10 and 15 years. Just choose the color of the dye. After all, under the influence of a hot environment, it fades in a matter of years and bright colors are not appropriate here.

How to paint pipes?

Painting pipes does not require any special skills. Even a beginner in the field of painting can do this job. However, there are still some subtleties in this procedure.

Therefore, before painting the pipe, you better listen to the following recommendations:

Do not paint the pipe over the remaining layer of old paint. It is better to remove all traces of the work of previous painters to the surface of the metal. As a last resort, it is allowed to leave intact those layers that are no longer separated from the surface of the pipe. However, all bubbles, scales and loose areas must be removed mercilessly.
hold off on painting the cold pipe. After all, moisture always settles on the surface of such a pipeline - condensation.

Always prime the pipe surface. Yes, for this you will also have to buy a primer. But when you see how much paint can go on a pipe without a primer, you will simply be horrified! So primer is not an additional expense, but a means of saving!
use different tools. Don't settle on just one option: just a brush or just a roller. After all, the same paint for hot pipes is best applied not with these tools, but with a spray gun. So just buy a brush, a roller, and a sprayer. In any case, they will be useful to you. After all, this is not the last time you paint a pipe.
apply layers in different directions. That is, if you applied the first layer along the movement of the liquid in the pipe, then the second layer must be applied across the flow of the transported medium.
Do not start painting without calculating the volume of paint itself. Especially if you use a non-standard color scheme obtained by mixing several colors.

Based on the last point, the most important intermediate step preceding the dyeing procedure is calculating the volume of purchased dye. Therefore, we will further study this point in a little more detail.

Color solution

What color should you paint gas lines?

According to the source of information (Safety Rules for the Gas Distribution System), painting occurs as follows:

1. A gas pipeline passing above the ground must be painted with two layers of yellow paint. Varnish and enamel of a similar color are also allowed. The dye must meet the requirements of the substance for work on the outside of the product. Color marking is necessary to identify an object.

2. The gas system, which runs over the facades of the structure, may have the color of the structures that enclose it.

Painting of internal gas pipeline structures inside residential premises and the color scheme for them are not provided at all.

Owner search

Who is responsible for painting the gas pipe?

Many people ask this question. Unfortunately, the person responsible for such a process has to be found separately in each individual case. In such cases, you must be guided by the gas pipeline line maintenance agreement.

In certain areas, responsibility is distributed in this way

1. In apartment buildings, pipeline lines inside each apartment must be painted by the owners of the apartments. Those gas pipes that run along facades, entrances or streets must be painted by the gas supply companies or local utility service (the terms of the service contract must contain such obligations). To divide the zone, you must be guided by the walls of the apartments

It must be taken into account that such duties relate only to painting pipes. But maintenance actions regarding the shut-off elements of the valves should be performed only by the gas service. 2

In private houses, the gas pipeline located on a private plot is painted by the owners of the house. The gas pipeline located in a public area was painted by representatives of the gas service. A gas pipeline that runs through the private territory of a house may be controlled by an organization that supplies gas, but then such an authority may require house owners to pay for the service of painting gas pipeline structures

A gas pipeline that runs through the private territory of a house may be controlled by an organization that supplies gas, but then such an authority may require home owners to pay for the service of painting gas pipeline structures.

How to calculate paint consumption?

Paint consumption rates can be determined using one of two popular methods:

determining the rate of paint consumption for painting pipes using an online calculator;
determine the standards using the hint on the label, which determines the consumption of a specific amount of paint for a certain area.

To calculate the amount of coloring composition using an online calculator, you need to know the following geometric parameters of the pipe:

section index (mm);
length (m).

You also need to select one of the options for applying the compositions and the online calculator will give you the approximate amount of paint that will be required to paint the pipe in one or two layers.

Paint for pipes: how and with what to paint communications?

A good pipe paint can do a lot! It can enhance the corrosion resistance of the product, extending the service life of the pipeline. It is capable of turning a terrible pipe into a completely tolerable, if not presentable, product. It makes it possible to cool the transported medium, reducing the temperature on the surface of the pipeline. In short, pipe paint solves many problems.

That’s why the pipes have been painted, are being painted, and will continue to be painted, always and everywhere! And given the popularity of this finishing operation, every plumber, plumber, installer or any other piping specialist should gain knowledge about the process of painting pipes. Therefore, now we will figure out how, and, most importantly, what pipes are painted with.

Types of paints for external and internal gas pipelines

Almost any external compositions that can provide reliable anti-corrosion protection are suitable for external gas pipeline structures.

Alkyd enamels (PF-115). A classic option that has been used for many years. The advantages of alkyd enamels are that they are resistant to weathering. After drying, they form a dense layer, the service life of which is at least 5 years.

Polyurethane coloring compounds. Provide good adhesion to the pipe and have a high coefficient of elasticity. The service life of these compounds ranges from 10 to 12 years.

Two-component epoxy compounds. They are resistant to wear and less elastic than polyurethane coatings.

Dispersions of aluminum or zinc powder in varnish, represented by organic material. They are the most resistant to corrosion compounds. The service life of a pipeline structure that has been painted with this composition can reach several decades.

Paint for internal gas pipes should not be vapor permeable to ensure the pipe is insulated from water vapor and oxygen. Almost all types of paint compositions are suitable for painting internal gas transmission lines (for both external and internal work).

Special attention should be paid to fire-resistant coatings, which, when directly exposed to high temperatures, turn into carbon foam. This coating can protect the pipeline from exposure to flame for 45 minutes

Composition selection

To ensure the best effect from using paint for heating pipes, when choosing a composition in a store, it is better to purchase paint with the inscription “for heating radiators” or a similar mark. Such a coloring mixture will be resistant to high temperatures, and when heated it will not change its color. One of the budget options is PF-115 enamel, which meets almost all the basic requirements given above. Heat-resistant paint KO-168, which has a silicon base, is also very good.

It is better not to use oil paint for pipes heated to high temperatures, since the oil composition will certainly fade or turn yellow after some time. In addition, oil dyes have an unpleasant, persistent odor during painting and drying.

Alkyd enamel for heat-conducting pipes

This enamel consists of alkyd varnish (pentaphthalic, glyphthalic) with the addition of vegetable oils and a solvent (white spirit). It has high elasticity and is quite durable. Currently, these enamels are popular and are used in many areas of painting.

The advantages of alkyd enamels include:

However, alkyd paints have not only advantages. The disadvantages include:

There is a pungent odor because the composition of these enamels includes white spirit. The smell lasts for several days. It is also possible for it to appear after the first start of the heating system.
Long time for complete drying (24 -36 hours), which increases the time for painting work.

Alkyd enamel PF-223 is quite suitable as a paint for heating pipes; PF-115 can also be used for heating systems.

Heat-resistant acrylic enamel

Odorless pipe paint is acrylic enamel. Due to the fact that it does not have a pungent odor, this enamel is an ideal paint and varnish material for work carried out inside residential premises. The painted surface becomes absolutely smooth and tactilely resembles plastic.

Since not all acrylic enamels are heat-resistant, when purchasing, you must carefully read the information regarding the temperature range of its use. The minimum value for using these enamels is 80 ºС.

A significant advantage of these paints is their drying time - for the first layer the value ranges from ten minutes to one hour, and from one to two hours for the second. To achieve a high-quality result, it is necessary to prime the surface to be painted. When carrying out work, it is necessary to avoid contact with moisture on the surface to be painted.

The consistency of acrylic resembles medium-thick sour cream; it does not spread, which eliminates the possibility of smudges. As stated above, this enamel should be applied to a previously primed surface in two layers. Violation of painting technology entails a significant deterioration in its quality.

The only drawback of using this material is its low resistance to mechanical loads.

Silicone and powder paints for metal

These two types of paints are the most resistant to high temperatures.

If the heating system is systematically exposed to overheating, then silicone paint is exactly what you need to paint the heating pipes with. After all, this coating is guaranteed to withstand heating up to 350 ºС. This paint consists of silicone resin with the participation of aqueous solvents. Semi-matte shine is a characteristic feature of the dried layer of this paint.

Silicone paint is unpretentious when painting - it does not require priming and is applied directly to the metal. Resistant to external influences. Durable. The disadvantages include the high price.

Powder paint is the most stable and durable of paints and varnishes at present. Used in industrial conditions.

Before you start painting the gas system, you need to sand it down to remove any old coating or rusty inclusions. Next, you need to free the pipes from dust accumulations and contaminants. After which, the gas pipes must be covered with a primer material intended specifically for metal products. But after all the work has been completed, the communications begin to paint.

According to the requirements of the state standard, gas lines must be highlighted with yellow paint. This is done so as not to confuse the gas networks with other pipes in the room. Painting is permitted with any type of paint that is suitable for metal products and is suitable for both external and internal work.

how to paint a gas pipe in the house

Previously, pipes on the street were painted red. In most cases, the pipes located in the room acquired the color that matched the interior or was liked by the residents. Pipes in a room can be painted with inexpensive paint, saving money. It will last a long time.

But if the gas system is installed outdoors, then it is necessary to choose a coloring agent that can ensure long-term coverage. It’s better if you first clean the pipes from rusty formations, prime them, and only then paint them, so the coating layer will last longer.

what paint to paint a gas pipe on the street

Material selection

When choosing a primer you need to be careful

You need to pay attention to what is written on the can; you should purchase a primer that is suitable for application over rusty areas

In addition, soil liquid also comes in several versions, namely in different colors, from black to green and blue. Having made a choice of color, you need to calculate the required volume.

It is recommended to buy one liter of varnish and two liters of soil liquid using this formula. It is worth purchasing the varnish that is suitable for coating metal products.

This is necessary so that, due to the porosity of the soil liquid, the wet environment does not get on the metal pipe, as rusty spots will subsequently form.

For this reason, it is worth adding a good quality varnish to the soil mass, which will ensure:

1. Pores will not form;

2. There will be no rust;

3. The pipes will have a glossy appearance for a long time.

After the choice of materials is made, you need to mix them and before applying the mixture to the surface of the pipe, you need to wipe the pipes with a rough sponge. Then, lubricate the gas line evenly, without missing a single centimeter. This can be done directly over the rusty areas. After completing this work, you will immediately see how the appearance of the gas system will change.

Of course, it is worth paying attention to special types of paints that are designed for metal products. Before purchasing, you need to read the information on the jar label, it should say, for example, has anti-corrosion properties, is intended for metal products, may have the inscription 3 in 1

how to paint a gas pipe

In addition, it can quickly ignite, so when choosing it, you should be careful. The main thing is that from the information received it can be concluded that the dye will transform the rusty sections of the pipes, then the painted layer of the gas line will be enough for a long time.

In accordance with building codes and regulations, paints and varnishes are used that can withstand changes in environmental temperatures and the influence of rain, snow, hail and other things.

The main thing to remember is that the coloring agent must be one of the types of oil or nitro-enamel waterproof products. The surface of the pipe must be painted yellow; the valve can be painted blue.

how to coat a gas pipe The state standard determines the colors for painting pipes, depending on the liquid being transported:

1. Pipes transporting water are painted green;

2. In a steam system, the pipes should be painted red;

3. Air ducts in blue;

4. Gas lines are assigned a yellow color;

5. Networks conducting acid should have an orange color;

6. The wire supplying alkali is purple;

7. Lines supplying liquids, both flammable and non-flammable, must be brown;

8. Pipelines transporting other substances have a gray appearance.

Paint for metal products can be found in any construction department.

o-trubah.com

What is stated in the regulations?

They indicate the color that gas pipes should be painted. In accordance with the color standard cards, they must have yellow color N205-206 (GOST 14202-69).

Street sections of the gas pipeline must be painted one yellow color. Gas pipes may be painted to match the color of the house façade if the appropriate permit is obtained from the organization servicing the gas pipeline. The color of pipes inside housing is not regulated by regulations.

Special requirements for the color of pipes are not a special whim of gas workers. This is a special coloring that shows what substance is transported through the laid pipes. With its help, if a gas leak occurs, emergency service specialists will quickly find the problem and fix it, which will allow them to prevent a strong gas explosion or fire.

If the pipe is painted any other color, then in an emergency when the owner of the house is not present, emergency service specialists will be disoriented and will not be able to quickly fix the problem, which can lead to tragic consequences.

The “Safety Rules for the Gas Distribution and Gas Consumption System”, clause 2.3.9 PB 12-529-03 also states that paint must be applied to pipes in two layers. In this case, they must first be coated with a primer and other preparatory work must be done.

First of all, you need to protect the wall from possible contamination. Place a sheet of newspaper behind the pipe and secure it, for example, with masking tape. Put on a disposable glove from the supermarket and take a thin strip of foam rubber. Well, then, you understand. I just grab it by the pipe and pull the foam along the pipe.

For such purposes, special brushes are sold, with a thin and curved handle. There are different sizes. Ask around in stores that sell paint or at the market, it’s always cheaper there. I bought several for myself, and I can paint pipes and batteries anywhere.

Choosing paint for painting gas pipes

Alkyd paint is most often used to paint gas pipelines, as well as other metal surfaces. Name according to GOST - PF-115. Since it is made from resin, the paint is viscosity and thickness.

It should be noted that it has an unpleasant, pungent odor that takes a long time to dissipate. Another disadvantage is that paint is flammable, and gas is a flammable element.

Among the main advantages of alkyd paint: high strength and resistance to precipitation. It can also be applied to hot surfaces. Another advantage is low cost.

It is not recommended to use alkyd paint in cold weather, since there is a high probability that it will not dry on the surface, but will freeze

When choosing which paint is best to paint the surface of a gas pipe within an apartment, it is not necessary to purchase only the recommended options.

You can use other coloring compounds:

polyurethane paint - has an elastic structure, good adhesion and durability;
epoxy - characterized by durability, but not elastic;
electrically conductive substance - recognized as the most reliable coating due to its high anti-corrosion properties and durability.

Despite the fact that there are paints that can be applied to rust, it is recommended to pre-treat gas pipes: clean the surface of old coating and rust, degrease the prepared surface, and then coat it with a primer.

To paint pipes indoors, it is allowed to use interior paints. The only thing is that the coating should not be vapor-permeable, because the main task of the paint is to insulate the surface of the pipes from oxygen compounds and moisture

Modern dyes intended for gas pipes have specific names. Most often, the word “paint” itself is not on the label, so the average person faces difficulties at this stage.

To apply a protective and decorative coating to a metal pipe, special compounds modified with anti-corrosion additives are used.

The most popular paints for gas pipes today:

Epostat is an epoxy primer-enamel for metal with anti-corrosion properties, heat- and frost-resistant, quick-drying;
Zinconol - protects metal in any climatic conditions, has excellent adhesion and protects against corrosion;
Nerjachim - protects metal, can be applied to rust, protects against corrosion, dries quickly;
Polyurethol - does not require preliminary priming, is resistant to acids, water, and petroleum products.

The technology for applying paint to a gas pipe is no different from painting any other metal material. The only caveat is that when removing old paint, it is prohibited to use heating devices.

Features of dyeing technology

Before painting these pipes, it is necessary to carry out preparatory measures.

First you need to clean them of old paint and rust with a wire brush. The use of solvents facilitates this procedure. To protect your respiratory system from harmful fumes, you must wear a respirator.

After cleaning the pipes, their surface must be thoroughly degreased. The consumption of the degreaser per 1 m² can be found on its label. Next, you need to apply two layers of primer to the pipes. This should be done with a brush.

Then you need to wait for the primer to dry, which takes 24 hours. If the room temperature is less than 15°C, it will take longer to dry. Then you need to apply paint evenly to the pipes so that drips do not form.

It needs to be applied in a thick layer. After the paint has dried, you need to apply the next layer. This painting technology allows for maximum protection of metal structures from corrosion.

Gas workers recommend painting gas pipes with yellow paint. True, this does not apply to pipes located in apartments and individual houses. They can be painted to match the design used in the home.

The pipe must be painted with a soft brush, and the coloring composition must be applied in small portions so that drips do not form. In this case, the brush must be held perpendicular to the surface to be painted. To apply paint to hard-to-reach areas of the pipe, you need to bend the brush. It is better to paint the pipe before wallpapering the walls or finishing with other materials.

When painting with alkyd paint, the second layer must be applied after 4-6 hours. Modern paint compositions can dry faster, so you need to look at their packaging for the exact time.

How to paint a gas pipe in an apartment. Painting gas pipes

A common occurrence in our homes is communication pipes. And if some of them can be closed, for example, in a gypsum plasterboard box, then this number will not work with gas pipes. Gas services require that their communications be open so that gas leaks can be detected and measures taken.

There are, of course, ways to get around this rule, for example, by hiding the tubes behind a removable grille. But mostly gas pipes are open. A rusty pipe in the middle of a renovated room does not look very impressive, so something needs to be done, and more specifically, paint the gas pipe. About paints Gas pipes, like any other metal surfaces, are painted with alkyd paint. In appearance, it differs from any other paint in that alkyd is more viscous and thick. This is because this paint is made from resin. You need to work with it extremely carefully: Firstly, it is flammable; Secondly, if such paint gets on the skin, it will not be possible to clean it with soap and water; Thirdly, alkyd paint has a very specific odor, so the room in which it is done painting must be well ventilated. But alkyd paint has plenty of advantages, it is very durable, and in addition it can be applied to hot pipes. In the cold season, this paint can be used, but there is a chance that it will freeze faster than it dries. Therefore, if external work is expected, it is better to carry it out not in severe frost. We are all accustomed to seeing yellow gas pipes on the street, this is also a requirement of gas workers. But there is a caveat: if the pipes go along the facade of the building, they can be painted in the color of the facade. In an apartment, you can paint the pipes in the color you want. Due to the fact that the gas pipe is open, it can be painted in the color of the interior so that it does not catch the eye. Although the more traditional color is white. There are paints that can be applied directly to rust. But still, before painting gas pipes, you need to make the necessary preparation. The pipe must first be sanded, partially or completely removed the old paint, and then degreased. Don’t be too lazy to do this, and then the pipe will be even, smooth and will look quite nice. How paints behave when painted You need to paint with a small brush, and to avoid smudges, it is better to apply it in small doses and perpendicular to the pipe. If the pipe runs along the wall, the brush can be curved to paint the back. But in any case, it is better to paint before further finishing is done on the walls, because it is very difficult to remove alkyd paint, for example, from wallpaper. If you can’t paint the pipe well in one go, you can repeat the procedure after waiting a certain amount of time, sometimes 4-6 hours, and sometimes a day, depending on the manufacturer. This paint is also called radiator paint, that is, it is suitable for heating radiators. Another common paint is called PF-115, this is the name according to GOST. Many manufacturers produce this paint.

No. 6. Pipe in a box - is it possible or not?

The methods listed above only allow you to decorate the gas pipe, but not hide it. If you really don’t want to tolerate gas pipes in plain sight or if it’s completely impossible to fit them into the interior, you can build a decorative box in which to hide the pipes, but in this case two conditions must be met:

at least part of the box must be removable; if necessary, access to the pipes must be obtained as soon as possible;
the box must have ventilation in the form of perforations or grilles. Otherwise, even with a small leak, the gas will gradually accumulate and eventually provoke an explosion.

Many people ignore these two requirements, simplifying the process of building a box. Some people believe that a 2-3 mm thick steel gas pipe cannot pass gas at all. Unfortunately, such misconceptions can sometimes be very costly. In addition, at the first inspection, the gas service will detect a violation, issue a fine and oblige you to release the pipes from the blind box. It’s better not to take risks, not to create unnecessary problems for yourself and immediately arrange everything according to the rules. We will need to create a removable ventilated shield in the box, and its decor can be anything.

If you need to close both the pipes and the meter, then it makes sense to build a box from plasterboard. This is not difficult to do - the principle of working with drywall has long been clear to everyone. Sequence of work:

make markings and determine where the metal guides will be located. The width of the box must be sufficient for equipment maintenance;
installation of the frame using a level;
measuring the resulting structure and cutting drywall to the required size;
installation of drywall. It is better to cover part of the structure with a lattice decorative panel, which can be easily dismantled if necessary.

If we are talking only about a pipe, then the task is significantly simplified. Guides can be built parallel to it on both sides from a metal profile or wooden beam. You can attach any material to them that suits you in appearance, provides ventilation and can be dismantled in a matter of seconds using a screwdriver or screwdriver. You can use polycarbonate. A fragment of the required width is cut from the sheet along the rigidity lines. The segment is bent along the fold lines until a U-shaped overlay is formed. Holes are drilled in it for future installation. The box is attached to the previously installed guides using dowels. In the most inconspicuous places, you can drill several holes on the polycarbonate for better ventilation.

Instead of a polycarbonate sheet, craftsmen also use perforated plywood, cardboard sleeve, bamboo trunk, and other materials. The operating principle is unchanged. You can use frosted glass, plastic, lining, wood and more - the main thing is that the decorative panel can be easily removed. In addition, you can find ready-made designs made from different materials and different colors on sale. They are easy to install and disassemble. It is better if the chosen decor is supported by other elements in the kitchen.

The main advantage of a well-organized box is the ability to hide the pipe from view, but in some cases you will have to say goodbye to a certain amount of useful space.
