Cracked paint is sometimes called "alligatoring."

Cracked paint can definitely be an eyesore in an otherwise well-decorated room. Cracked paint is a phenomenon also referred to as "alligatoring," and it happens when you apply a second or third coat of paint before the first coat has dried thoroughly. If your painted walls are in such a state, you don't have to live with them as-is. A few restorative strategies, along with a fresh coat of properly applied paint, can get rid of your cracked paint.

Step 1

Put on your goggles and nose and mouth mask. Run the electric sander along the surface area of the cracked paint. You might need to use a step stool or ladder if you're dealing with higher sections of a wall.

Step 2

Brush down the entire surface area of the space after you've sanded it. It's important that you thoroughly brush away all the dust. Apply a single coat of high-grade undercoat with a roller or paintbrush. Allow the undercoat to dry completely according to the manufacturer's instructions. If you're not sure of the timing, just give the undercoat 24 hours to dry.

Step 3

Apply a single coat of the paint of your choice with a roller or paintbrush. Make clean, uniform strokes when applying the paint.
