How to Repair Brick Veneer Tile

Paint over minor cracks or chips using brick-red paint and a brush. From a distance, this will be indistinguishable from the surrounding brick, which varies in color slightly anyway. For slightly larger cracks, fill with masonry sealant, allow to dry according to manufacturer's instructions and then paint.

Chisel out severely cracked or crumbling tiles and accompanying grout. Chip them away carefully to avoid damaging the wood underneath.

Grind away the dried cement underneath with the grinder. Again, be careful to remove only the cement so you don't damage the wood underneath. Removing all of the dried cement makes replacement and fitting of the brick veneer easier.

Apply a new layer of brick cement with trowel or putty knife to the spot where you removed the tile or tiles. Use the cement recommended by the brick veneer manufacturer so it'll support the weight of the tile.

Place a new brick veneer tile over the cement. Press the tile against the wood until it takes hold. Follow the established pattern, if any, or select tiles close in color to existing work so the repairs blend in.

Dry for 24 hours or longer if recommended by the cement manufacturer.

Apply brick cement between tiles with putty knife to fix the brick veneer tile in place. Wipe off excess on the brick immediately, before it dries.
