Most homes less than 50 years old have drywall. Drywall is also known as Sheetrock, gypsum board, or wallboard.
Drywall repairs are pretty simple to do, but they take some time because you have to wait 8-12 hours between steps. Obviously, it might be best to do your drywall repairs in the evening so you can let the material dry overnight. It's also a good idea to wait until your walls are in need of a new paint job because you'll have to paint over the repairs anyway.
To complete the repairs you'll need...
- A clean cloth or sponge
- A utility knife
- Some sanding block or sandpaper (80 to 100 grit and 120 to 150 grit)
- A putty knife
- Some joint compound
Step 2: Use the 180 to 100 grit sandpaper and lightly sand the dent to remove any small flecks of drywall or paint chips that are still hanging on to the surface.
Step 3: Using your utility knife, gently cut away any torn pieces of drywall that are still attached to the area.
Step 4: Wipe the dent with a damp sponge or cloth to remove anything that might still be there.
Step 5: Use your putty knife to fill the dent area in with joint compound and smooth the area down. Wipe off the putty knife and allow the repair to dry (about 8-12 hours or overnight).
Step 6: When the repair is dry, sand with the 120 grit sandpaper.
Step 7: If the surface still looks bumpy or rough, you need to do another cycle of applying joint compound and letting the area dry. when you're finally happy with the repair job, use your damn cloth to wipe the area off. Now your ready to repaint the wall.
