How to remove old paint from walls: ways and tools

Getting rid of unnecessary paint on the walls is a difficult task. It has to be faced often, because for a long time in our country it was a favorite material (because of cheapness and availability in stores). Most problems are caused by oil paint. It is very resistant and difficult to remove. In this article, let's try to figure out how to remove the old paint from the walls, and which compounds are best used.

On what does the complexity of work depend?

The severity and durability of the process will depend on:

• The composition of the paint;
• The number of layers deposited;
• Surface on which it was applied.

Strangely enough, to repair the walls of the house and remove the paint is easiest if it is applied in several layers. The most difficult variant is a coloring material on a surface that has not been plastered beforehand or applied to concrete.

Ways to get rid of the old paint: safe and not very

For each surface will suit its own means. Today there are several options, how to remove the old paint from the walls:

- method of chemical exposure;

- mechanical;

- heat treatment;

Electromechanical method.

How to get rid of the old paint on the walls with the help of chemical treatment?

This method consists in coating the surface with the removed paint with a special compound. Wait for the recommended time and clean the wall. The liquid for removing the paint can be different. For example, liquid glass, quicklime and even calcined soda.

On the one hand, everything is simple: apply a product, wait and clean. But this method has a few not very nice properties. This, above all, high toxicity of chemical compounds. This method is not very effective with a thick layer of paint, besides such compositions work well with powder paints, oil can not succumb.

The surface treated in this way requires obligatory washing, not once. When working, it is necessary to use special protective clothing, to protect against harmful chemical composition of face and hands, since the liquid for removing the paint is very aggressive against the skin and mucous membranes. For the time of work with such funds from the premises, it is necessary to remove people who are not engaged in repairs, flowers, animals. The room in which work is carried out should be constantly ventilated.

Liquid glass when frozen on the paint forms a silicate film, which is easily removed together with the old paint.

Calcined soda and quicklime will help to get rid of paint with minimal effort and time. 400 grams of soda should be mixed well with 1400 grams of lime and applied to the wall. In twelve hours the wall will be easily cleaned.

How to remove old paint from walls with high temperatures?

Heat treatment consists of heating the old paint with a blowtorch, iron or building hair dryer. Under the influence of high temperatures, the colorful composition softens and is easily removed. The main thing is to warm the surface well enough.

In the case where there is no construction hair dryer or blowtorch, you can use the iron. Warm the paint through a sheet of foil or a tin plate. The softened layer can be removed with a spatula. Experts, despite the simplicity of the work, do not recommend using this way, because:

- there will be a strong smell in the room (you can get poisoning);

- You can melt the decor elements (skirting boards, panels, polyurethane stucco, etc.);

- there is a risk of damage to the electrical wiring.

The way is far from the best. You can use it if the room is small or you need to remove the paint from a small section of walls or ceiling. As in the previous method, professional means of protection are needed.

Mechanical method

This treatment option is considered the safest and most affordable. Although it is quite laborious, but in this case, it justifies itself. Especially if it's a wooden wall, the paint is old oil, and the room is poorly ventilated.

The main tools that will be required for cleaning walls: a scraper, spatula, cutting tool, water or a special non-toxic compound. The initial stage of the work is cutting. Then the surface is wetted with water, and a non-toxic paint remover for walls is also suitable, so that it is well absorbed. When the surface of the substance to be removed gave cracks, it is possible to take a scraper or spatula and proceed with the removal of the paint.

The work progresses slowly and hard, but it's safe. That's why this method is very popular.

How to remove old paint from walls with the help of electrical appliances?

The method of machining painted walls. Stripping is carried out with the help of a grinder with a special nozzle or drill. Excellent results can give a wide range or a nozzle with a stiff bristle on a bulgarian or perforator.

Disadvantages of the method are only two: noise and dust, or rather, its immense amount. Many repair teams use this method to clean the walls of the substances to be painted. Although it is worth noting that this method is rarely used in indoor rooms. It is more suitable for outdoor work or for partial surface treatment. Today, there are devices with built-in vacuum cleaners that capture up to 95% of flying dust. A drill or a Bulgarian requires personal protective equipment, especially a respirator and special glasses.
