Over time, paint on an old radiator can crack, swell or peel off. To restore the attractiveness of their heating radiators, they need to be repainted. However, everyone faced with this task logically asks the question - how to clean the battery of old paint? In this article, we will share with you the simplest and most effective ways so that you can quickly get rid of the paintwork that has lost its attractiveness.
Tools and tools
Depending on the cleaning method you choose, you need to acquire the required materials and tools:
- Special aerosols that can be purchased at building and paint stores.
- Personal protective equipment - rubber gloves, respirator, overalls, specialized sealed goggles.
- Mechanical tools - chisels, spatulas and brushes with metal bristles, paint brush.
- Active compositions for chemical removers.
- Building hair dryer or blowtorch.
- Sandpaper.
Removing old paint using aerosol
If, in order to clean the battery of old paint, you have chosen a special spray in the form of an aerosol, then proceed as follows:
- Spray the product evenly over the product. One aerosol is usually enough to treat both the outer and inner surfaces of the battery.
- Wait about half an hour. By this time, a chemical reaction should have taken place and the paint will begin to bubble.
Important! For the full effect of the product, the ambient temperature must be at least 10 degrees C, therefore it is recommended to carry out the treatment in a well-ventilated room or in summer.
- The loosened paint layer can be removed from the battery surface with a chisel, metal brush or spatula.
Important! If it was not possible to completely remove the old paint from the battery, or if it was applied in several layers, then after a while the procedure should be repeated.
Features of the work and the choice of paint
Before painting the batteries, the old layer is removed from them with a brush or chemical remover.
In the course of painting radiators, the old coating is removed, the surface is prepared and a new layer is applied. For processing, the following paints and varnishes are often used:
- Acrylic based. Such paints do not have a pungent odor, are easy to apply, and retain their brightness for a long time. To obtain the required shade, a pigment is added to the base.
- Alkyd paints. The finished coating is more durable, but it can turn yellow if the batteries are painted white or light.
- Based on heat-resistant varnish. Such paints are relatively inexpensive, resistant to strong temperature changes.
- Silicone compounds. They cover the radiators themselves and metal heating pipes.
Thermal cleaning method
You can remove old paint from the battery by exposing the radiator to high temperatures. To use this method, you may find the following tools useful:
- building hair dryer or blowtorch, with the help of which the product will be heated;
- metal brush with a sufficiently high rigidity;
- metal spatula;
- rags.
Cleaning work is recommended to be carried out in the fresh air, which is associated with the danger and toxicity of substances that are released when the paintwork is heated.
Important! If you nevertheless decide to carry out work in the apartment, then you must use a building hair dryer, which does not carry such a danger as a blowtorch.The walls in the room must first be covered with a protective layer of cardboard.
Instructions on how to remove old paint from a battery using temperature exposure are as follows:
- Using your chosen equipment, heat the surface of the painted product until the coating starts to bubble.
- Hot paint, without waiting for it to cool, is cleaned from the radiator with a spatula or removed with a rag.
- This kind of work is carried out until the entire surface of the battery is rid of the obsolete paintwork.

There is a special construction hair dryer for removing paint. Or liquid, it is true, very caustic
Better to change them right away, there will be less problems
With a spatula, and then a foot. Sausage to metal is not necessary. The main thing is that the surface is evenly displayed.
in hardware stores (or construction) metal brushes are sold, for a battery it is better to take with a long "nap". the sound will be unpleasant, but the effect is obvious.
In household goods, old paint remover is sold - on acid Very caustic thing. The effect is 100% of the current, you need to be very careful, following the instructions and without children in the room where this cleaning

An industrial hair dryer will help you. Exactly! Good luck!
make a fire, paint and scorch. In general, put aluminum in it like - EARTH AND SKY
Until the batteries are turned off with a construction thermal gun and remove the paint, since a lot of energy is spent on heating the cast iron. Thermo gun, narrow, hard spatula. And when they turn off the sandpaper, go for a walk and you will be happy. A Bosch or Makita thermal gun - you need a temperature of the order of 650-700 degrees. Ask around at the box office.
It will be very difficult to remove it more or less qualitatively. The geometry of the radiator is rather complicated - it is difficult to paint it, let alone remove old layers of enamel. The technology is not easy. And there will be a lot of fuss. And do you have a hair dryer? Such advice is not suitable for everyone, you know. We painted our radiator directly over the old paint, good imported enamel, suitable for painting radiators.
I do not recommend burning the radiator with a hairdryer. The gaskets will burn. Then you have to regroup the entire radiator. Kmslotoy poisoning is also risky for the same reason. leave it as it is or throw it away.

It's impossible to answer better than Kostya Komar's answer! This is exactly the case when "our sorrowful work" will be lost. Whatever it concerns, in the end it is cheaper and more aesthetically pleasing to replace it with a new one (of course, if it is not a rarity).
Old paint remover can be used. It is used in car repair. Apply with a brush and stand for some time according to the instructions, then easily clean it off with a narrow spatula. The smell is not very pleasant. You need to ask the seller that the product does not contain paraffin, if paraffin is present, none of the paint will fall on top.
Chemical wash
One of the traditional and simplest ways to remove old paint from a battery is to use a chemical cleaner and brush. However, this method has a rather serious drawback - sometimes it is very difficult and inconvenient to apply the active compound and remove paint from the inner surfaces of the radiator.
Important! When choosing a chemical remover, give preference to water-based formulations, because they practically do not flow down vertical surfaces and lie fairly evenly on the surface.
The washing process itself is carried out in accordance with the following algorithm of actions:
- The substance is drawn directly from the factory container onto the brush.
- The composition is applied to the surface of the radiator with wide strokes.
- Depending on the life of the coating and its layering, a chemical reaction takes place within 5-15 minutes.
- Without waiting for the paint to dry, it must be removed from the surface with a spatula or a brush with metal bristles.
- The surface of the cleaned battery is washed with soapy water at room temperature.
Mechanical cleaning
If you decide to use a mechanical method to clean old paint from the battery, be prepared for the most time consuming. However, its cost is also minimized.
Here, the basic rules are as follows:
- You can remove large cracks and bubbles using a perforator on which a nozzle in the form of a hammer or spatula is put on.
- For cleaning the rest of the surface, use tools such as sandpaper, files, metal brushes, etc.
Important! To achieve the desired result, you can also clean the surface using a grinder with a brush or a sander.
After the end of the procedure for mechanical cleaning of the battery from the old paintwork, it is imperative to treat the surface with a solvent, which will ensure an excellent overlay of new paint layers.
Basic security measures
Since in most cases the removal of paintwork is carried out using strong chemicals, you need to worry about observing the basic measures for safe work:
- Carry out cleaning work in a well-ventilated area or outdoors.
- Protect the surrounding interior items from chemical splashes, especially plastic and rubber products.
- Protect your hands with rubber gloves when performing work.
- Use special glasses with a high level of tightness to protect the mucous membranes of the eyes from the corrosive effects of chemicals.
- Wear protective clothing to prevent poisoning and remember to wear a respirator to keep your respiratory tract from irritating.
Types of paints
The end result largely depends on the choice of material. Use metal paint for high temperatures. Otherwise, the coating will crack or come loose from the battery, or it will smell of paint and varnish reagents when heated. The choice of paints suitable for working with cast iron radiators is wide enough.
Alkyd enamels form a high-strength layer on metal surfaces that will last for many years without staining. Alkyd compounds are also not afraid of high temperatures. The disadvantage of such paints is that they emit a strong odor when working with them, and also at first when the radiators are warming up.
Acrylic enamels are made using organic solvents. They are durable and form a shiny glossy finish. When dry, they emit a specific odor. When the radiators are first heated, acrylic enamels do not smell as strong as alkyd enamels.
Water-based paints intended for painting batteries dry quickly and do not emit an odor. In addition, they retain their properties when exposed to temperature and serve for a long time, maintaining the integrity of the coating.
Traditional oil paints are used less and less. They are being replaced by quick-drying and more convenient paints and varnishes. As for nitro paints, they are too toxic, therefore, they require the use of personal protective equipment when carrying out painting work.
Remember that paint does not conduct heat well. For this reason, it is not recommended to apply it in a thick layer on batteries, otherwise their heat transfer will decrease. In this regard, metallized paints are the best (the well-known "silver" belongs to them), which least of all affect the characteristics of heat transfer of cast iron.
Of course, radiators should be painted before the start of the heating season. But what if the repair had to be done in the fall or winter? And here there is a solution: special heat-resistant paints that can be used "hot". These include formulations made with the addition of silicone resins and aluminum. This type of paint conducts heat well and stays on metal for a long time.
