It is common for a wall coating to peel off, especially as a result of water damage. It is not necessary to remake it completely if a sufficiently large part adheres properly to the wall.

Resumption on friable wall
1. As a result of water damage or infiltration, the wall may remain brittle even if it is completely dry. It is then not possible to coat it properly, the coating can not adhere to the support. Apply a coat of paint to the area to be repaired. Allow it to dry completely before coating.
2. Apply the repair plaster with a wide painter's knife. Smooth as best you can. Let it dry completely before sanding (use a sanding block).
Lay a corner reinforcement
1. Apply the plaster generously on one side of the corner. Let dry.
2. Apply plaster on the other side of the corner to reshape the edge of the corner.
3. Place a metal profile on the corner. Press the profile so that the coating flows back through the perforations. Let take the coating.
4. Cover the metal profile with a few centimeters on either side of the profile.
5. To remove the level difference, apply a new coat of plaster on each side of the edge.
Restore a chipped edge
1. Dust the chipping with a paint brush. Moisten the masonry to prevent it from drinking the mixing water from the plaster.
2. Apply the cutter to one side of the wall as formwork. Apply the coating. Do the same on the other side of the edge of the wall. Let dry and sand (be careful not to break the edge!).
