This document provides tips for DIY drywall repair, including fixing cracks, small holes, large holes, corners, and popped nails. It recommends using a mudded sponge and joint compound to repair cracks. For small holes, use a patch and apply joint compound over it multiple times. Large holes require professional help to shape the damaged area and insert a new drywall piece. Damaged corners involve cutting out old metal bead and attaching new bead before applying joint compound. Popped nails should be removed and reinserted with joint compound applied over the nail. Professional help is preferred for extensive repairs.
