Instructions
-
-
1
Sand down the cracked wall using a sanding buffer with a medium-grain sanding ring. This smooths down edges, chipping and roughness on the wall and around the cracks.
-
2
Vacuum the wall, surrounding areas and in the cracks using a shop vacuum.
-
3
Fill a spray bottle with water.
-
4
Cut a piece of plaster gauze patch to measure the width and length of one of the cracks, then place the patch over the crack.
-
5
Spray the patch with water to dampen it. This will moisten the plaster and allows the patch to adhere to the wall. Allow the patch to dry for 2 hours. Repeat to cover all of the cracks with patches.
-
6
Spread spackle over the patches using a flat-ended trowel. Scrape the trowel across the edges of the patches to make the edges flush with the rest of the wall. Allow the spackle to dry for 6 hours.
-
7
Sand the wall patches using fine-grain sandpaper, moving the sandpaper in small, circular motions. This will allow the spackle to become even more flush with the wall.
-
8
Vacuum the wall again using the shop vacuum to remove any debris and dust.
-
9
Fill a paint tray with latex paint, then coat a paint roller in the paint.
-
10
Apply three coats of latex wall paint over the repaired wall using the roller, allowing the paint to dry for 8 hours in between each layer.
