What You Can Realistically DIY
Small holes up to about an inch — nail holes, screw holes, small anchors — are manageable with minimal materials and skill. For anything larger, especially anything requiring texture matching, the results are usually visible through paint.
Materials for a Small Hole Repair
Lightweight spackle or joint compound. Putty knife. Fine-grit sandpaper (120–220 grit). Primer. Matching paint.
The Process
1. Clean the hole — remove any loose paper facing or debris. 2. Apply compound — press spackle into the hole, slightly overfilling. 3. Feather the edges — smooth so it blends into the surrounding wall with no hard edges. 4. Let it dry completely — lightweight spackle dries in a few hours; joint compound overnight. 5. Sand smooth — flush with the surrounding wall. 6. Prime and paint — spot prime before painting; unprimed compound absorbs paint differently.
When to Call a Professional
Holes larger than an inch, water-damaged areas, textured walls where matching matters, and high-visibility locations where a visible patch isn't acceptable.
