How to Darken Brick

Clean the brick with a power washer to remove any loose soil or dirt. Turn the tip of the application wand to a flat spray pattern and step back at least 3 feet from the bricks while spraying them. Let the bricks dry completely.

Mix the brick stain according to the package directions. Brick stain kits usually include gloves, a liquid additive and a powder coloring agent to which you apply water. Stir the contents thoroughly.

Dip a paintbrush into the stain mixture. Paint a small area of brick in an inconspicuous test area. Let the stain dry and observe the color. To lighten the stain, add more water. To darken, add a second coat or select a darker stain. Be aware of the extra cost, however.

Paint each brick individually with the paintbrush, taking care not to paint the mortar in between each brick. Wipe any drips up immediately with a wet shop towel.
