How to choose the most optimal way to remove paint from walls?

There are several factors that influence the choice of this or that method of cleaning the wall from the old paint:

• the surface on which the paintwork has been applied, and also what exactly you plan to do with it in the near future;
• the type of paint, the number of layers, as well as the strength of its adhesion together with the surface;
• tool availability;
• budget, which was planned to spend.

All the paint is divided into several types: water-based, acrylic, and also oil. The paint could be applied to wood, metal, plasterboard or concrete. The oil paint is most difficult to remove from the surface of concrete walls.

Important! You, of course, may not know what color is on the surface of the walls of your home. In this case, you, whatever one may say, will have to experiment a little with the methods of elimination on a small section of walls. To begin with, try the least laborious, as well as sparing methods.

Mechanical method

Taking into account the physical characteristics of the paint, which, during chemical as well as thermal elimination, releases strong enough toxic substances, it will be most optimal to use the mechanical method to remove the old paint from the walls.

A well-known very old grandfather's method is labor-intensive, slow, but it is also cheap, not traumatic, the least harmful is the notching of the wall surface with the help of an ax. In order to clean the old paint from the walls, you need, in fact, an ax, muscles and water.

How to proceed:

1. First, make a notch with an ax.
2. After this, carefully drizzle the wall with prepared water, wait a few minutes until it absorbs.
3. Then clean the paint with an ax.

Important! In order for the work to go much faster, more efficiently, correctly select the angle of inclination of your ax.

Most often this method is used if you plan to further wall cladding with ceramic tiles, because the adhesion of the tile together with a nonsmooth surface is ideal.

Important! Regardless of the fact that the method is somewhat laborious, and also slow, it is quite effective when it is necessary to process a small area, and also practically the only option in poorly ventilated rooms.

Mechanized mechanical methods

In order to speed up the mechanical removal of paint from the concrete surface, to make it easier for yourself to work, to increase its productivity, we advise you to use a mechanized method. You can use the Bulgarian together with a wide range.

Important! During such cleaning, there will be an incredible amount of dust: after 1 minute of work you will have to wait about 20 minutes until all the dust settles. But today there is already an excellent new equipment, which includes a vacuum cleaner, which allows you to remove the old paint from the walls as cleanly as possible.

There is another way to remove old paint from walls - a perforator with special nozzles. As a nozzle, a chain is used for the drill and grinding wheels. This method - a fairly effective and cheap option for removing paint, as well as rust from concrete, wood, metal surfaces.

Environmentally friendly ways

Relatively little dust is formed during the ripping of the old swollen coating with a spatula or other improvised device. Such mechanical cleaning requires a lot of patience and takes quite a lot of time. With scrubbing movements you can clean the surface even in the most inaccessible places - in those in which it is impossible to use other devices.

Advantages of the method:

• Minimal formation of noise and dust.
• Possibility of total application absolutely on all sites.
• It does not require additional material costs for various chemical products, or for paying for energy, as well as for the purchase of a non-expensive instrument.
• Does not require any special skills to own a device or knowledge of technology.

Disadvantages of this method:

• The time costs are quite large.
• A significant amount of monotonous physical labor.

How to remove water-based paint from the surface of walls?

Not taking into account the fact that acrylic or water-based paint is very soluble in water, after it dries, it can not be washed off with just the same tap water. And in bathrooms, on kitchens use a special water-resistant version of water-based paint.

But mankind came up with a few tricks that allow you to defeat the "stubborn enemy":

• Drain the walls with warm water, wait for a few minutes. At this time, the paint will absorb water and swell. You can easily eliminate it with a spatula.
• For soaking the ceiling, use a soft roller of sufficiently large diameter.
• During drying, the paint will peel worse, which is why during the work, always wet it with water.
• All the scraped softened paint stains the coatings quite strongly, that's why before closing the work, close the floors with newspapers or with a plastic wrap.
• If waterproof paint is used, soaking will be meaningless, which is why it is necessary to eliminate the paint on absolutely dry coating with a spatula or a sanding machine. The latter option is extremely different in the formation of an incredibly large amount of dust. This you must take into account and take various precautions, for example: wear a respirator, construction glasses, gloves, hair cap.
• A sufficiently thick layer of waterproof paint can be annealed with a construction hair dryer or with a blowtorch. With a thin layer, this method is not recommended.

Universal method for water-based paint:

1. Prepare a paste, that is, a solution of PVA glue - it must be very liquid, or take a plain wallpaper paste.
2. Lubricate the surface to be cleaned with a prepared compound and immediately fill with newspapers.
3. Wait until the glue dries, and then sandpaper together with your paint.

Important! In particularly difficult places with a strong coating, you can use a metal spatula.

Chemistry

The most harmful, associated with toxic fumes, is the use of special washings. They are on sale in the form of aerosols, liquids, gels. The release form will affect the efficiency, convenience and speed of surface treatment. Therefore, carefully read the information on the package or tube - there it is usually written for which paint is suitable solvent and for which material the basis of the walls.

Well-established in consumers such washouts:

• Docker S4, S5;
• Anti-theft;
• solvent 647 and 646;
• Fail-4.

Now you have a complete idea of ​​all the possible ways and for sure you could decide how to remove the old paint from the walls. We hope that you managed to do this quickly enough and the repair did not drag on indefinitely because of the difficulties in the preparation of the walls.
