What Is the Process for Painting Exterior Brick Houses?
Do not paint bare brick.
Before you attempt to paint your brick house, you should understand that bare brick is not conducive to paint adhesion and will shed new finishes. You must employ the proper preparation and application techniques, or your paint job will most likely fail.
- Cleaning
- Exterior brick is most often coated with unseen dust that greatly inhibits primer and paint adhesion. Use a pressure washer to eliminate this dust. Once the brick is clean, wait about four hours for the brick to dry.
Priming
- Apply a base coat of primer, prior to painting. Use an acrylic latex primer for exterior brick surfaces. Use a roller to apply the primer and a paintbrush, manufactured for use with water-based coatings, to prime the mortar between the bricks.
Painting
- Once primed, exterior brick houses will accept new paint. An acrylic latex paint is best suited for exterior brick because the paint possesses great elasticity, allowing it to expand and shrink in hot and cold temperatures. Apply the paint just as you did the primer. Multiple coats are not necessary unless the primer bleeds through.
