- 1). Check for any efflorescence caused by water migrating to the surface of the brick and evaporating, leaving behind mineral salt residue on the surface which usually looks white. If efflorescence is present, mix a 5 percent muriatic acid and water solution, and scrub the surface with a bristle brush. Wear eye protection and rubber gloves. Rinse well with water, and allow the brick to thoroughly dry for 72 hours.
- 2). Brush or roll on a primer coat of bonding primer, which will grip tight to the surface of the red clay brick to provide a stable surface to apply the cover coat of paint.
- 3). Brush or roll a final cover coat of latex, interior paint or water proofing paint.
