How to Seal Brick Veneer
- 1). Clean the brick veneer with fresh water and a brush to remove surface debris. Turn off any garden sprinklers that could spray on the brick veneer. Wait at least 24 hours, until the brick veneer is completely dry, before continuing.
- 2). Pour a small quantity of sealant into the sprayer reservoir. Cap the sealant container immediately to prevent drying, evaporation or contamination.
- 3). Spray a liberal coat of sealant over a small test patch of brick veneer. The goal is to saturate the area in one or two coats, rather than to build up thin layers of light sprays.
- 4). Wait three hours. Test the sealant with a drop of water. If the water absorbs into the brick veneer, darkening the surface, you must apply a thicker coat or additional coats.
- 5). Spray the remainder of the brick veneer with a thick, event coat of sealant. If you must apply a second coat, wait at least three hours.
- 6). Clean the paint sprayer with lacquer thinner to avoid clogging.
