How to Cover Exterior Brick With Texture Paint
- 1). Put on rubber gloves and goggles. Mix 1/2 cup of trisodium phosphate (TSP) and 1/2 cup of laundry detergent into 1 gallon of water in a bucket. TSP is quite caustic, so you should always wear goggles when using it.
- 2). Spray the wall with a garden hose to knock off big clumps of dirt. Ideally, use a high-pressure nozzle to really give it a good pre-cleaning.
- 3). Apply the TSP detergent solution with a brush. Work it into the grout and along the brick. Trowel Trades recommends using a "long-handled, stiff fiber brush" for this purpose.
- 4). Spray the wall again to wash off the cleaning solution.
- 5). Paint the wall with a latex-based primer designed for exterior brick. Hometips.com recommends using a 1-inch nap roller.
- 6). Use a paintbrush to go back over the wall and work primer into any areas you missed. Allow the primer to dry for as long as specified on the container.
- 7). Paint the house with textured paint specifically designed for masonry. Apply it with a roller, and retouch it with a paintbrush, as with the primer.
- 8). Allow the paint to dry. Apply a second and third coat as you wish.
