Reattach any loose drywall to the studs using drywall screws. Work from the edge in toward the loose area.

Sand the area with medium-grit sandpaper attached to a sanding block to ensure a level surface. Follow with finer grades of sandpaper until smooth.
Paint the damaged area with two coats of oil- or alcohol-based primer. Use a brush or roller, and allow the spot to dry between coats. This seals away any residual dampness and prevents the stain coming through.
Fill in any low areas or patch holes in the repair area using a putty knife and drywall compound. Apply it directly over the primer. Sand the drywall compound with successive grades of sandpaper on a sanding block. Feather the edges until the repaired area is smooth and blends with the rest of the wall. Wipe away dust with the damp sponge. Feel the wall for dampness and visually check for signs of mold or mildew.
If either is present, wipe the surface well with a diluted mixture of water and chlorine bleach to remove it. Allow the water-damaged area to dry completely, if damp. Training a heater or fan on the spot, if possible, will speed this process. Paint over the area with a thin coat of oil- or alcohol-based primer using a brush or roller. Feather the edges into the undamaged areas with a near-dry brush to avoid leaving raised areas on the undamaged paint. Let it dry, then recoat.
Brush or roll on a finish coat of paint matching the rest of the wall. If necessary, recoat the entire wall or ceiling to ensure the new coat matches the old paint. Related Articles.
