Houses shift over time and with extreme changes in weather. Shifting can cause stress cracks in the drywall, most commonly occurring at the corners of doors and windows and extended out on the wall. If your home is in an area with shifting soil, it is almost impossible to avoid stress cracks, but you can fix drywall cracks with stress crack tape. Left unrepaired, the cracks provide an entry into your home for insects, and allow heat and cool air to leave the home.
Things You'll Need
- Utility knife
- Fine-grit sandpaper
- Soft cloth
- Stress crack tape
- Drywall compound
- Putty knife
- Wall texture
Remove the loose drywall from around the crack. Cut dangling drywall paper with a utility knife.
Sand the area around the crack with fine-grit sandpaper until you've removed all the texture from the area. Wipe the area with a soft cloth to remove sanding dust.
Place stress crack tape over the crack, and apply a coat of drywall compound over the tape with a putty knife. Allow the compound to dry completely.
Sand the drywall compound with fine-grit sandpaper. Wipe the area with a soft cloth to remove sanding dust. Apply two more layers of drywall compound to the crack, sanding after each application.
Texture the wall to match the surrounding area. You can purchase spray-on texture at a home improvement store. Allow the texture to dry completely.
Touch up the repair area with paint that matches the rest of the wall.
