How to wash off paint at home? Any repair in the room begins with the preparation of surfaces, with cleaning the walls of old paint. This is not an easy task, which is associated with the creation by manufacturers of new stable and durable coatings. However, there are different ways to remove any kind of paint with your own hands. How to do this, the article will tell.

Why flush old paint

In order to start cleaning surfaces, it is necessary to understand that the main reason that serves to timely remove the old coating from the walls is to ensure the future, full adhesion of their base with the new material applied to it. Old paint significantly reduces adhesion, which does not depend on the finishing methods used.

Some, in order not to remove the old coating, leave it, others are limited to half measures:

• New compositions are applied to the walls, for example, "Concrete contact", But its effectiveness will only be with deep absorption of paint into the wall. If it begins to exfoliate, the use of such a primer does not make sense. A roughness will appear on the upper layer, but this will not increase its resistance. Moreover, if reinforcement is located close to the wall surface, such aggressive compounds can provoke the appearance of metal corrosion.
• They make deep grooves or notches on the walls with any sharp tool: a chisel, a durable spatula, an ax. Notches can increase the adhesion of the surface and the new material, but they must be applied very efficiently: make them deep enough and very much, which is quite difficult.

Tip: Do not leave paint! At any time, a new coating may peel off the wall and fall.
