Why Your DIY Drywall Repair Doesn't Look Professional

You patched the hole, painted over it, and you can still see exactly where it was. That's the most common result of a DIY drywall repair, and it's almost always down to a few specific steps. Here's what usually goes wrong and how to get it right.

Using spackle on anything bigger than a nail hole

Spackle is fine for nail holes and small dings. Larger repairs need joint compound (drywall mud) and, for holes, a patch or a new piece of drywall. Spackle shrinks and cracks when it's built up thick.

Skipping or choosing the wrong tape

Cracks and seams need tape under the compound, or they come back. Paper tape is stronger for seams and inside corners; mesh tape is easier for small patches. Tape that isn't fully embedded in compound bubbles and peels later. See why drywall tape peels.

Piling on compound in one thick coat

A professional repair is several thin coats, each one feathered out wider than the last and allowed to dry. One thick coat takes forever to dry, shrinks, and leaves a hump you can see from across the room.

Oversanding

Sanding too hard cuts through the compound and scuffs the drywall's paper face. The fuzzy, roughed-up paper shows through paint. Sand lightly, with a fine grit, just enough to smooth the edges.

Skipping primer

Joint compound absorbs paint differently from the wall around it, so an unprimed patch looks dull or shiny compared with the rest of the wall, even in the same color. This is called flashing. Prime the patch before you paint.

Not matching the texture

Most Central Florida walls and ceilings have knockdown or orange peel texture. A smooth patch on a textured wall stands out no matter how well it's painted. Matching texture takes practice: the size and spacing of the pattern, and how flat it's knocked down, all have to match. See texture and finishes.

Painting just the patch

Even with the right color, touching up a small spot often shows, because the old paint has faded. Painting the whole wall, corner to corner, is often the only way to make a repair disappear.

Fixing the symptom, not the cause

A crack that keeps coming back, a stain that returns or a sagging spot all point to something behind the drywall: settling, a leak or loose fasteners. Patching over it without fixing the cause means doing it again. See types of drywall cracks and their causes.

Cutting into the wall without checking first

Before you cut out damaged drywall, check for wires, pipes and ductwork behind it. A small cut can become a much bigger repair.

When to call a pro

Small nail holes and dings are a good DIY project. For larger holes, ceiling repairs, water damage, or when the finish needs to be invisible, a professional repair usually costs less than redoing a DIY attempt.
