For any apartment renovation, one of the points is to paint the radiators. What kind of paint to take, what parameters to focus on, how to clean and paint the batteries?
first, you need to remember what properties should paint have for radiators:
- 1-heat resistance (withstand high temperatures)
- 2-high adhesion to metal
- 3-anti-corrosion qualities.
Most of the paints and enamels offered for sale have the listed features. They are resistant to temperatures up to 90 degrees, but the painting process is recommended to be carried out outside the heating season, that is, on cold batteries. The reason for this is the lack of evenness, a decrease in the quality of the coating when the heating is turned on, shifting, and cracks are likely when drying.
Now on the market of building materials, there are varieties of enamels that allow you to paint heating systems at high temperatures. We are talking about heat-resistant species that do not lose their properties after drying, retain the quality of the coating and color.
How to choose paint?
You should focus on the composition, choosing the appropriate material.
1) alkyd enamel has a strong specific smell. Using this type, you will have to provide intensive ventilation. One layer dries in two hours.
This enamel is highly resistant to household chemicals, so it is often used in painting works in the kitchen.
Perfectly combined with paint surfaces, perfectly fits on such coatings.
2) Acrylic paint is ideal for painting batteries in rooms with high humidity, for example, in the bathroom.
This variety has high heat resistance, is applicable to a large temperature range, is famous for its excellent water resistance, and does not have a pungent smell.
Dries on average one hour, the next layer is allowed to apply only after this time.
1 – SELECTION OF THE DESIRED PAINT
During the heating season, with hot radiators, you should initially make sure that the paint does not exclude the possibility of applying at high temperatures. Most of the coloring agents are designed for painting on cold surfaces. If you miss this moment, you may be disappointed with the result when there are irregularities, spots, or cracks.
The coating, which is not intended for use on hot radiators, often dries very quickly and unevenly, which does not allow the paint to fit in a uniform layer.
2-CLEANING THE PAINTING AREA
Before starting work, the heating elements must be cleaned, degreased, and dried.
If this is the first application to the battery, there is no old paint, it is recommended to decrease,” walking ” on the radiator with sandpaper, remove dirt, apply a layer of primer. It is important to take the primer as directed by the manufacturer of the dye.
If there is old paint, then you can do the following:
– view the status of the previous coverage. If there are cracks, chips, or detachments, it is advisable to remove the previous layers. Then comes a plan of action similar to that for unpainted batteries.
– if the condition of the previous staining is good, even, there are no cracks and flaking, just refresh the color. To do this, you will need to clean the object with sanding paper to a matte finish, remove dust, and degrease.
3 – THE PAINTING PROCESS
Elements of the heating system are painted in 1-2 layers using a paintbrush. Less often use a paint sprayer. A roller is an unsuitable tool, as it creates inconvenience when applying.
The brush is selected in advance, taking into account the parameters and location of the surface to be painted. Someone is more convenient to work with a wide brush, someone narrow, long. With the purchase of this tool, there will be no questions, there is a huge selection available in construction stores for every taste.
If you decide to apply the paint in 2 layers, then first you need to sand the first layer that has dried.
Using these tips and applying the entire algorithm of actions, you can quickly and easily restore the heating system, giving it a beautiful and well-groomed appearance.
