Mosses are small plants that thrive in damp, dark areas. Bricks in shady areas are susceptible to moss not only because of the shadiness, but also because the pores in bricks retain water. Some people may find that moss adds a touch of elegance, but others may disagree. Also, moss can pose a threat on walking surfaces as it can be quite slippery. Moss removal from bricks can easily be done without any prior experience. In many cases, all it takes is a matter of minutes to have it off of the bricks.
Power-wash the entire moss-covered brick area. Make sure the nozzle is set so the water is widespread, rather than a thin stream. Also, do not let the pressure exceed 3000 psi as it could break chunks out of the brick. The power washer should take care of most moss problems, but stubborn moss may take a little extra work.
Mix 1 part bleach to 10 parts water in an empty spray bottle. A good amount for the average spray bottle is half a cup of bleach and 5 cups of water.
Put on safety glasses and rubber gloves for protection from the bleach. Spray the bleach mixture on stubborn moss and let it sit for two to three minutes.
Scrub the moss with the stiff-bristle brush. Rinse the bricks with water once you are finished scrubbing.
Repeat as often as necessary.
