Step 1: Select a patch and prepare the wall Place a drop cloth beneath the area on the wall to catch dust and debris. Select a patch from the textured patch kit that will cover the damaged corner entirely. Mark where the patch will go on the wall and lightly sand the texture off the surface area under the patch. Wipe the area clean with a damp sponge.
Select a patch that matches the texture and covers the damaged corner completely.
Step 2: Apply the patch When the wall area is sanded, clean, and completely dry, you are ready to apply the patch. Peel the backing off the back of the patch and press the patch in place, pressing firmly around the edges without pressing on the section over the damaged area.
Press the adhesive patch over the damaged area, applying pressure around the edges but not over the damaged section.
