How To: Paint Brick
Painting brick involves a special approach that differs slightly from that used to coat drywall or wood.
Painting bricks requires some special considerations. Wet down the surface first to ensure better paint adhesion. Use a latex-based masonry paint and apply with a very thick-nap roller. Apply the paint generously allowing the excess to fill all the nooks and crannies found in most masonry surfaces. Overlap your strokes to ensure complete coverage.
