Can I paint hot batteries with paint or enamel?

The acquisition of new radiators can be called an expensive pleasure. But if in your apartment or house there are cast-iron batteries, then they can be given an attractive appearance by painting the surface. Do this work better in the summer, when the smell of paint can be quickly removed by opening the windows and doors. In addition, after the end of the heating season, the surface of the battery will be cold, which can be called ideal conditions for such work. If you still wondered whether it is possible to paint hot batteries, then it is necessary to take into account some nuances.

Recommendations for painting hot batteries

If you decide to paint the radiator in the heating season, then you need to choose the right equipment. To do this, it is best to use a nebulizer, with which the application of the composition can be carried out quite neatly and quickly. The layer of paint will form a thin even layer. The lower part of the battery is usually treated with a brush.

When choosing a paint, it is necessary to pay attention to its properties and quality. The desired composition must undergo a temperature increase. If you are faced with the question of whether it is possible to paint hot batteries, then you should take a more serious approach to choosing a colorant. For example, alkyd enamel is excellent for this. However, when used, it will emit a pungent odor, and with time and at all can change the color, acquiring a yellowish tinge.

The most advantageous option for dyeing hot batteries is acrylic paint. It dries in a short time, and there is no smell when applied. It is not affected by the temperature jump. If you have wondered if it is possible to paint hot batteries, then you should know that these works require the need for training. The surface of the radiator should be cleaned of grease, dust and contaminants. You can do this with a soda solution. Anointing will remove the old paint layer. After the surface is sanded, it should be primed.

Recommendations for the preparation of a radiator

If you are faced with the question of whether it is possible to paint hot batteries, you should become more familiar with surface preparation technologies. The first involves the use of a chemical method, while the second involves a mechanical one. The chemical method of treatment is expressed in the use of substances that dissolve the old layer of paint. After using such a composition, the surface can be easily cleaned.

It should be remembered when performing these manipulations on safety measures. The master should wear protective goggles and gloves. If you do not want to spend money on chemicals, you can use a mechanical method. It consists in the use of scrapers, sandpaper, as well as drills with special nozzles.

If you, too, decide the question of whether it is possible to paint hot heating batteries, then you should know that when carrying out such work, you should refrain from painting the cranes. If this recommendation is ignored, then the use of stop valves may be accompanied by difficulties. But the radiators themselves should be painted in two stages, carrying out the application from the top down.

Carrying out the primer

To implement the primer, you can use the domestic composition GF-021, which is combined with enamels MA and PF. If you plan to use imported dyes, then for the priming you should purchase the material of the same manufacturer. Oil paint, applied in one coat on the primer, can increase the heat dissipation of the battery by 5%. If more than three layers are applied, the heat transfer will decrease by 1%. A dye based on lead and aluminum will also help reduce heat loss.

Coloring recommendations

Now you know whether it is possible to paint hot batteries with paint. If a convector is installed in your apartment, then its invisible elements and pipes should not be painted to increase its heat transfer. This recommendation should also be applied to convection aluminum plates. They are located on the pipes and easily clogged.

Removable body should be painted, for this purpose, the paint perfectly odorless. Solving the question of whether it is possible to paint hot batteries with enamel, it is necessary to pay attention to the material of the radiator. If it is cast iron, then from the surface of the structure it is necessary to remove the dust, and then rinse it with water and degrease. To do this, use a one-percent solution of ammonia.

If the surface is chipped, then they must be treated with a primer with anti-corrosion properties. At the next stage, the surface is covered with putty and ground. It is worth considering that the paint for hot radiators will cost more than others, so you need to assess the situation, deciding whether you can wait until the end of the heating season. It is recommended to apply paint as thin as possible.

Recommendations for the painting of bimetallic and aluminum radiators

Bimetallic and aluminum radiators are painted in the plant conditions by powder composition. It will be extremely difficult to achieve such a surface on your own, but if you decided to update such a device, its working surface must be prepared according to the technology described above, and then covered with a primer and a layer of alkyd enamel.

In the presence of strong defects, the coating should be removed to the metal, a grinding machine is ideal for this. Next, the master will have to coat the surface with a primer. Only after you can proceed to staining.

Use of alkyd paints

If you decide whether it is possible to paint hot heating radiators with paint, then consider as an example an alkyd composition that is capable of operating at temperatures up to 150 ° C. Manufacturers ensure that light colors do not turn yellow if the temperature does not rise above 120 ° C. Alkyd paint after application for some time will give off an unpleasant smell, but it quickly enough weathers. At each start of heating the smell can appear again, but for a short time.

Conclusion

Home masters often wonder about whether it is possible to paint hot batteries with acrylic paint. It almost does not smell, and is also the most popular because of the affordable cost. The base enamel is a product with a white structure. In order to change the shade, a tinting pigment is added to the ingredients. For such coatings, the temperature threshold is somewhat lower than that of alkyds and is 80 ° C. However, in practice it turns out that this is quite enough.
