How to repair small drywall cracks
In nearly every inspection we always see a few small scuff marks, stains, scratches and small cracks in drywall. Generally this isn't a concern unless it's accompanied by other factors like foundation movement, door and windows being stuck, deflection, or larger gapped cracks. However we if your drywall is cracked, there are a few steps you can take to repair it:
Clean the area around the crack: Use a dry cloth to dust off any debris or loose drywall compound around the crack.
Sand the area: Use a fine-grit sandpaper to smooth out any rough edges around the crack.
Apply drywall compound: Use a putty knife to apply a thin layer of drywall compound over the crack. Wipe off any excess compound with the knife.
Sand the repaired area: Once the compound has dried, use a fine-grit sandpaper to smooth out the surface.
Prime and paint the area: Once the repaired area is smooth, apply a coat of primer and then paint to match the surrounding wall.
If the crack is large or there is a significant amount of damage to the drywall, it may be necessary to cut out the damaged section and replace it with a new piece of drywall. This is a more involved repair process and may require the assistance of a professional.
