Before starting to paint the walls, experts conduct an inspection to identify poor adhesion of old paint. The next step is preparation in order to remove the falling-off layer and soak the walls with a special, protective solution. After reading this article to the end, you will learn how to prepare the walls so that the paint does not peel and does not fall off during painting work.
Preparatory stage
The most important stage in this work is preparation, because the quality of this measure was made, future repairs will depend. Before painting the walls, you should tap and clean the surface with a brush with steel pile. If the old paint was water-based, it means it will work well. But with oil paint you have to suffer.
Oil paint from concrete walls does not come off well, so there are two options:
- Clean off the paint with a spatula or using a drill and a special circle with metal hairs. The work is painstaking and dusty, it is recommended to work in goggles and a mask.
- There is no desire and ability to clean off to the end, then you should do so. If the paint adheres firmly to the surface, then it is possible to putty with oil putty, having previously untreated the walls, for reliable adhesion between the wall and the putty.
After filling, when the putty is dry, all the relief must be cleaned up with sandpaper with a small fraction. Soak the surface again with a deep penetration primer and you can start painting the walls.
Life hack how to paint the walls correctly
After thorough preparation, you can proceed to painting the walls. In order not to wash away paint, floors and doors, it is recommended to close them with oilcloth. You need to start from the corners around the perimeter of the wall. To do this, paint with a brush all the places where the roller is missing. Until the paint has dried, you need to quickly paint the wall, from corner to corner without interruption. Otherwise, a run on dried paint will stand out, as it turns out that this is a different layer.
Important! If you started to paint a wall or ceiling, then do not break in half and do not wait for it to dry, as the connecting place of dry and wet paint will stand out in a strip that will be difficult paint over.
It is convenient to paint using an extension cord for the roller. No need to get up on a stool or staircase. To paint on the roller stacked evenly, roll the roller on the plywood or purchase a special bath-cuvette.
