Painting Your Brick Is a Big Decision: Here's How to Do It

It's a contentious issue. Half of the designers, paint contractors, and homeowners vehemently say that brick should be left in its natural state—unpainted. The other half says that not only can poor quality brick be painted over, but good brick will look better when painted.

Painted Brick and Its Permanence

In the end, it has less to do with the look of it than with the permanence of the project. It is difficult to remove paint from brick: sandblasting; laborious manual stripping; or pressure-washing.

Consider that painted interior brick is even more permanent because it rules out the possibility of pressure washing or sand-blasting the paint, should you decide to reverse the project.

All of those methods have serious downsides. Many homeowners like to cover over the brick with stone veneer, which is a project no less permanent but one that conveys higher property value.

Undertake this project with much consideration and care. View it as irreversible.

Tools and Materials Needed

  • Brick conditioner
  • Elastomeric exterior masonry and stucco paint
  • Hand wire brush
  • Bucket
  • Mild detergent
  • Garden hose (or power washer)
  • Chlorine bleach (optional)
  • Roller, roller covers designed for brick/masonry, and paint tray
  • Canvas dropcloth
  • Exterior grade caulk


  1. Efflorescence is that white, chalky stuff that appears on brick. If you have any efflorescence, then you need to use a hand wire brush without water to remove it. If this is exterior brick, try lightly power-washing. Carefully wash it because using too much power will etch the brick.
  2. Does your brick have large cracks? Brush them out with the wire brush so that any loose material is removed. Seal with pure acrylic or silicone/acrylic caulk designed for exterior use.
  3. Often, the mortar is crumbling or even missing. This means that you need to repoint your mortar. Deeply inset or missing mortar means that your painting job will be that much harder. So, while repointing may seem unnecessary at this point, it will save you work later in this process.
  4. Scrub down bricks with mild detergent and scrub brush. Or use a power washer, if you haven't done this in an earlier step. If you have mold and/or mildew, remove by adding one part of ordinary household bleach to three parts water. Moss is relatively simple to kill with a spray-on fluid such as Bayer 2-in-1 Moss and Algae Killer.
  5. Wait for the brick to dry. Let the bricks dry thoroughly before attempting to paint. Because brick is very porous, it may feel dry to the touch but is wet inside. You may want to let a day or two of dry weather pass before attempting to paint.
  6. Roll, brush, or spray on a coat of conditioner paint such as Sherwin-Williams Loxon.
  7. Let the conditioner dry for three hours. Be careful not to let too much time pass or the surface will get dirty and need to be recleaned.
  8. Paint with a coat of 100 percent acrylic elastomeric wall coating similar to Valspar Duramax.
  9. Let dry thoroughly.
  10. Paint a second coat of elastomeric wall coating.
