As a surface exposed to the exterior, brick walls are vulnerable to outside elements including sun, rain, snow, mould, mildew, algae, smoke, bird droppings, sand and dust. If these are left to sit on the surface over long periods of time they will not only make such structures old and unsightly, but they will also cause material erosion. The longer you wait, the harder it becomes to remove such debris. Pressure washers are used to eliminate water stains, salt spots, mould, mildew, dirt, wasp nests, and debris left after construction (construction cleaning).
Often times when brick and concrete are involved, the rules change. Brick companies tell you to use low pressure when washing brick. They state around 500-1000 PSI should be sufficient enough and they also insist to never go over 1500 PSI. If you just blast the brick wall with 5000 PSI you will scar up the bricks and cause a lot of damage. This is the major reason why brick cleaning jobs should be left to professionals.
Home builders are very familiar with how important it is to properly conduct post construction cleaning. A large part to pressure washing brick depends on how clean the bricklayers are. If they are sloppy or if they have been laid when it has been rainy, then the brick will be smeared and harder to work with. It also matters what type of mortar was used when the walls were built. There are two main types, type N and type S. In most cases type N is used for brick and type S for block. The difference is that type N has a compressive strength of 850 PSI and type S 1500 PSI.
Perform brick cleaning and pressure washing on a new building, before we start to pressure wash brick, we need to scrape the wall. These techniques are also good for after construction cleaning. We need to get off all the excess mortar left on the wall. We never just blast it off! A general rule when we cleaning brick is to pre-soak the area first and then apply BIO-Cleanse cleaning solution. Our chemicals are biodegradable liquid and is excellent for removing water stains, salt spots, mould and rust, which are very common on brick surfaces. It is absolutely safe around plants and grass, and as such, it is superior to other cleaning brands. Once the surface is wet we are ready to pressure wash. Start at the bottom of the house/wall and work across to the end of the wall, and then back to the bottom for a second run!
