You Will Need
- Joint compound
- Putty knife
- Utility knife
- Mesh tape
- Fine grit sandpaper rated for drywall
- Wooden block
- Contractor (optional)
Clean the area
Clean the drywall area and remove any loose bits of plaster, spackle, and grit, depending how wide the crack has gotten. Remove old tape, textures, or popped nail heads.
Cut a trench wider than the crack with your utility knife to get more surface area for the compound to adhere to.
Use mesh tape
Lay mesh tape in angled and deep spots that require too much compound to patch. Be sure to attach it an inch over either side of the crack.
Scoop out compound liberally with your knife and apply it to the area. Sweep the knife back and forth diagonally, angling it so the compound spreads and fills evenly. Use slow, careful pulls, feathering the compound.
Allow to dry
Allow the first layer to dry following the compound manufacturer's instructions.
Sand with the wooden block
Wrap the sandpaper around a small block of wood to get a flat surface and sand the area. Pass a damp sponge over the area after it is dry to inspect it for grooves and blemishes.
Skim on second coat
Skim on a second, thinner layer of compound. Dry and sand again, without being too aggressive. Paint the wall and no one but you will ever know.
