To patch drywall, follow these general steps depending on the size of the hole:
For Small Holes and Cracks
- Widen the crack or hole slightly with a utility knife to create a clean edge and remove any loose debris.
- Brush away dust.
- Fill the hole or crack with lightweight spackle or joint compound using a putty knife.
- Allow it to dry, then sand smooth and repaint as needed
For Medium Holes (about fist-sized)
- Cut a square or circle around the damaged area to remove weak drywall.
- Cut a matching piece of drywall to fit the hole.
- If needed, install backing support inside the wall by screwing in wooden strips that extend beyond the hole.
- Screw the drywall patch into the backing supports.
- Apply drywall mesh tape around the seams.
- Cover the patch and tape with joint compound ("mud"), feathering the edges to blend with the wall.
- Let dry, then sand smooth.
- Apply additional coats of mud as needed, sanding between coats for a smooth finish
For Large Holes
- Cut out the damaged drywall into a clean square or rectangle.
- Cut a new drywall piece slightly larger than the hole.
- Attach wooden backing strips inside the wall cavity if necessary.
- Screw the drywall patch into the backing strips.
- Apply mesh drywall tape around the edges.
- Spread joint compound over the patch and tape, feathering the edges.
- Let dry overnight.
- Sand and apply a second coat of joint compound, feathering further beyond the first coat.
- Sand smooth and repaint
Tips
- Use mesh tape for easier application and better adhesion.
- Feather joint compound edges well to blend the patch into the existing wall.
- Wear a dust mask when sanding.
- For textured walls, reapply texture after patching to match the surrounding surface
This approach covers most drywall patching needs from small cracks to large holes with backing support and finishing techniques to restore a smooth, paint-ready surface.
