7 Drywall Repair Mistakes That Show Through Paint

The patching mistakes that become painfully obvious once the paint dries.

1. Using too much mud

Several thin, wide coats are easier to hide than one heavy coat.

2. Rushing between coats

Compound that is still damp can shrink, crack, or pull loose when you sand or recoat it.

3. Not feathering wide enough

Each coat should extend farther than the last. A narrow patch creates a ridge or shadow after painting.

4. Sanding through the drywall paper

Seal fuzzy or torn face paper before adding more compound.

5. Not matching the texture

Practice first on scrap drywall or cardboard, then blend without leaving a halo around the repair.

6. Skipping primer

Joint compound absorbs paint differently than the surrounding wall. Primer helps prevent flashing and uneven sheen.

7. Judging only from straight on

Shine a work light across the wall from the side to expose ridges and hollows before painting.
