How to Paint on Patio Bricks

A brick patio is an attractive addition to a home. If you want to freshen up the look of your patio or make a decor statement, consider painting the bricks for a unique and stylish patio. Proper preparation and the right materials are key to doing a good job on your painting project.

Remove any efflorescence from the surface of the bricks. Efflorescence is a chalky white buildup that appears on brick because of chemicals leaching out due to the presence of water. Brush any affected spots with a wire brush to remove the residue.

Brush out cracks in the bricks with a wire brush to remove any dirt and debris. Leaving the dirt and debris in place will impede the painting process and promote the growth of mold and mildew, even after you’ve painted the bricks. Fill the cracks with a silicone caulk designed for all-temperature outdoor use.

Scrub the bricks with a mixture of 1 part bleach to 3 parts water to remove any mildew or mold. Mix the bleach and water in a plastic bucket and use a stiff-bristled nylon brush for this step. It may be necessary to do some sections several times to remove all mildew and mold if the bricks have a thick coat of mold or mildew. Rinse with water between applications.

Give the bricks one or two days to dry thoroughly. If you proceed while the bricks are damp or wet, you won’t get satisfactory adhesion of the paint or conditioner. This can cause flaking of the paint later on.

Paint the bricks with a coat of brick conditioner. This is available at paint supply stores. Apply the conditioner on small areas at a time, and strive for even coverage. Let the brick conditioner dry for 2 to 3 hours.

Apply your coat of paint. Use an elastomeric exterior masonry paint and apply with a brush or roller. Apply the paint to small areas at a time, and strive for even coverage. Bricks are porous, so be fairly liberal in your application of the paint. Apply a second coat if necessary for good coverage.

Warning

Wear gloves and use caution when using bleach.
