Why putty the walls?

An even and smooth base will make the application process easy and the result excellent. If you apply paint to an unprepared wall, then all the bumps, irregularities, cracks will be perfectly visible after the repair is completed.

In addition to the aesthetic function, the putty is also responsible for durability. It strengthens the walls and makes the coating more durable.
