Cosmetic makeup sponges are an effective way to repair and restore walls. The ability to modify their size to match the specific imperfection makes them very practical.
Once the cosmetic sponge is cut to the desired size, simply insert it into the hole snugly. Once in place, spackle the drywall, covering the sponge and surrounding area.
To minimize the need for excessive sanding, carefully glide the putty knife at an angle to remove any excess spackle and wipe the surrounding area clean.
Allow the spackle to dry completely, then sand the surface until it is smooth and wipe away any residual dust. Apply a fresh coat of paint to finish the drywall repair.
