Situations where it is required to clean the walls of paint, are often encountered. And if the process of applying coloring substances is not a complicated matter, then the process of removing them is much more difficult. Remove old paint in various ways: using a chemical, mechanical means, a construction hair dryer, a perforator. Each case requires its solution. And the first thing you need to determine what kind of paint will have to be removed.

Types of paints

The division of paints into types takes place according to the principle of their designation. There are for exterior surfaces, there are for interior, there are universal. All of them have different properties, have different characteristics, respectively, require a different approach to work.

Modern paint paints are divided into:

  1. dry building;
  2. oil;
  3. enamel;
  4. water-dispersion;
  5. water-based.

Choose a way with which you can remove a layer of old paint easily and simply, it is impossible without defining its appearance. This is the main question that should be considered before starting work.

Methods for removal of old colorants

Having determined the type, it is possible to begin to choose the way of its removal from the surface. Typically, experts identify 4 ways that will help get rid of the old coating layer:

  1. chemical;
  2. thermal;
  3. manual( mechanical);
  4. electromechanical.

The chemical method involves the use of a special flushing mixture, which contains corrosive chemicals. They spread an unpleasant smell and it is impossible to work with them without a gas mask. The washing mixture can only be used for powder paints. The mixture is evenly distributed over the surface, left for a while and removed together with the paint with a conventional spatula.

The thermal method is based on heating processes. For this purpose, use a simple blowtorch or construction thermofan. The surface is heated and the warm paint is scraped off by hand. But the method is very dangerous, and not in all cases effective. For example, it is easy to remove a heated layer from a tree, then it is much more difficult to heat and remove paint from concrete.

The mechanical or manual method is the simplest. It can be done with an ax, scraper and spatula. A sharp-pointed ax is made by small notches at a short distance from each other. With the help of a scraper or spatula, the layer is pushed and removed as scales from fish.

Electromechanical way strongly resembles manual. Only at the same time an electric drill or a Bulgarian is used. A metal hard brush is attached to the tool and the surface is cleaned. This method will help clear any kind of staining, so before you remove the paint from the wall, you can not think, and immediately use power tools.

As a rule, when removing oil paint, the thermal method is particularly effective. In this case, it will be better to remove the paint with a hair dryer, which is used in construction. Two people work: one heats the surface, directing the hot air flow to the desired place, the other quickly removes the softened composition with a spatula. The main thing in this process is not to overheat the layer, which will lead to charring of the substance and to remove it will be much more difficult. But this is not the only way to remove oil paint. This can also be done with a conventional iron and foil. A large-sized foil sheet is attached to the surface and ironed by iron. Immediately after this, the paint is scraped off using a scraper or spatula. It is possible to use liquid glass by covering the surface with it. When dry, it deforms and the process of peeling the film together with the paint takes place. Another solution is potassium carbonate: 0.5 kg is bred with 1.2 kg of quicklime, brought to a slightly thick consistency and applied to a painted wall or other surface. After 12 hours, the paint can be removed freely.

What to do if the surface is painted with water-based paint

This type of paint is the most unstable in relation to moisture. Its basis is polyvinyl acetate, which is very simply washed off with water. That is, before removing water-based paint from any surface, you need to buy only soap and sponge. The surface is wetted with water, the sponge is soaped and you can start rubbing the paint.

What to do if the surface is painted with acrylic paint

Acrylic paint is much more stable and it can not be washed off with a simple soap solution. It is much more effective to resort to mechanical means of removal - the disk of an angle grinder or a spatula. Still, in order for , how to remove acrylic paint, you can use old newspapers. They pasted the area to be cleaned and wait for complete drying, after which the paint is easily cleaned together with the newspapers.

It is possible to remove the paint layer even with a conventional chisel. Of course, it is boring and tiresome, but effective. Not good to get rid of the old paint will help wash the mixture and construction hair dryer. From all of the above, than to remove the old paint, you must choose based on the situation. Only the right approach will help to solve the problem quickly and effectively.
