Inside corner cracks in your drywall are surprisingly easy to fix. All you need are some basic supplies and a little patience. Here’s what you’ll need to make your repair:
TOOLS & MATERIALS
- Utility Knife
- Mud Pan
- Drywall Joint Knife
- Drywall Compound
- Drywall Paper Tape
- Sanding Block
- Paint Brush or Roller
When taking on this DIY task, be sure to equip yourself with the proper safety gear.
For hairline corner cracks, apply a thin bead of paintable latex or paintable silicone caulk over the crack. Then use your finger to smooth the caulk into the corner. For cracks larger than a hairline at corners or ceilings, first cut through the existing seam and trim away any loose drywall or tape. Cut a piece of paper tape to size and hold it along the middle crease. Apply joint compound to the corner. Then apply the new piece of tape to the area, using your joint knife to smooth it into place. Allow the area to dry. Then apply compound to one side of the corner. Once the first side is dry, apply compound to the other side of the corner. Let dry per manufacturer instructions and sand and paint as needed.
Your drywall repair is now complete!
