Repair a chipped coating before painting

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.

Necessary material

  • Brush to rechampir
  • Knife to coat
  • Sanding wedge
  • trowel
