Pressure Washing Brick
Brick is the classic home exterior that has stood the test of time and is as popular today as it was decades ago. Some people shy away from buying homes with a brick exterior because they don’t know how to maintain the brick. Pressure washing brick is as simple as pressure washing any other type of housing material, and with these tips you’ll be able to do it like a pro. Pressure washing will remove embedded dirt, stains and even moss, which has a tendency to grow on bricks that are in shady areas.
Inspect the bricks and replace any missing mortar between the bricks. This step is important and will prevent the water from seeping behind the brick. Making needed repairs is also a step that can’t be rushed and needs to done at least one week before you plan to pressure wash the house. The mortar needs time to harden otherwise damage can be caused by the water from the pressure washer.
Start the cleaning process by wetting the bricks thoroughly. Take your time and spray clean water on the exterior of the house from bottom to the top. Soaking the bricks with water prepares them for cleaning and makes the process easier.
Use Proper Detergent
Use a detergent that is specially formulated to clean brick. Use according to manufacturer’s directions and spray on bricks, starting at the bottom and working your way up to the top. Allow detergent to soak in for 10 minutes.
The key to cleaning brick without damaging them is more detergent, less water pressure. Start pressure at lowest setting and increase pressure as needed. Use a brush to scrub away tough stains instead of increasing water pressure.
After the detergent has had time to soak into the brick and lift out the dirt, it’s time to gently rinse all the dirt and stains away. Turn the pressure washer to a gentle spray pattern and begin rinsing at the top and work downward, moving the water wand from side to side. The gentle rinse will protect the brick from damage while rinsing dirt away.
Once the brick has been washed and rinsed, it’s time to apply brick and mortar sealer. Do this while the brick is still wet. Use an approved brick and mortar sealer and apply according to manufacturer’s directions.
