Why does water-based paint peel off

Many apartments use water-based paint for interior decoration. She shows herself well on ceilings and walls. If you select quality products, you can not worry about the appearance of surfaces for several years. However, sometimes after drying the paint there are various problems, such as: cracking, peeling, in some In some cases, bubbles and craters appear, and it is not always clear what to do with this and how to prevent such a phenomenon in others. rooms.

Often, the paint begins to crack and peel if it is applied too thick. The same thing is observed when the surface was painted at a high temperature, and it turned out that the upper layer dried out earlier than the lower one. If it is too damp in the room, then cracks can also appear after sudden drying. The paint falls off if the base is poorly prepared and some dirt and dust remains on it. If such problems arise, you need to remove all lagging paint with a wire brush, apply a primer and choose a better paint for repeated staining.

Paint can fall off in large pieces when poor-quality products are selected that have very poor adhesion to the surface and do not have the proper elasticity. A similar situation occurs when it is also applied with a too thick layer or is applied to a wooden surface without a primer. It is also necessary to remove all lagging material, sanded, if necessary, putty and primer, and then how to paint again. If there is a wooden surface, you must first apply a primer, then an acrylic putty.

The bubbles appearing on the walls and ceilings look rather unpleasant. This happens when moisture penetrates through the outer wall. To fix the problem, you need to remove the damaged layer, putty and cover with better paint, as well as be sure to eliminate the source of moisture.

By the way, a similar picture can appear if you purchased an old water-based paint, so be sure to you need to look at the date of manufacture and the expiration date when buying, and also make sure that the staining technique is correct. If a porous surface was painted, first a primer or putty coating will be required to level it, and then a layer of water-based paint.
