# Painting Concrete Block Indoors
Painting concrete blocks can pose a challenge. The cement blocks often shed salts that must be removed or neutralized before the application of paint. With the proper technique, however, the painted blocks should have a finish that will last a long time.
Things You'll Need
- Paint roller with 1/2-inch nap
- Pressure washer
- Masonry primer
- Finish paint
Instructions
-
-
1
Scrape the concrete block free of any flaking paint or loose mortar.
-
2
Pressure wash the concrete block to wash away any salts on the exterior. Alternately, the block wall can be washed with muriatic acid which neutralizes the alkaline salt.
-
3
Paint the concrete blocks with a masonry primer. This paint seals the concrete preventing the salts from forming on the surface and provides a surface for the finish paint. Use a paint roller with a 1/2-inch nap. Allow the primer to dry for at least 8 hours before applying any finish paint coats.
