What is Paver Brick Sealing and Pressure Cleaning?
Paver bricks are made of porous clay and contain seam lines between bricks, as well. Paver Brick Sealing is the process of applying a water-based or solvent based sealer to the surface of your paver bricks which helps protect the bricks from the elements as well as stains that form from tires or dirt. Prior to sealing, paver bricks must first be pressure cleaned to remove any existing surface stains.
Why is Paver Brick Sealing and Pressure Cleaning Important?
Paver Brick Sealing is important because it prolongs the useful life of the bricks as well as prevents future stains and “wash outs” from occurring. A “wash out” occurs when a great deal of water penetrates between the seams of the pavers and flushes the sand underneath them away, creating a void under the pavers which will eventually sink from their flush state. This most commonly occurs when there is a poor drainage plan for an area, or if a pipe bursts that runs underneath the pavers.
Paver Brick Pressure Cleaning is important because it removes any of the surface stains from your pavers. Over time, dirt, rubber tire marks, tree sap, and other natural materials may accumulate and mar the look of your pavers. Regular pressure cleaning prevents these stains from becoming permanent
How is Paver Brick Sealing and Pressure Cleaning Performed?
Paver Brick Sealer is applied with either a squeegee, a roller, or a spray wand, depending on the size of the area and the type of sealer applied. Water-based sealers can be applied to damp pavers, making them the ideal solution for pavers which were just pressure-cleaned. Solvent-based sealer can only be applied to pavers that are completely dry, so they are not recommended unless the pavers were freshly installed. The sealer is applied in a thin coat with uniform coverage. The sealer then cures over 24-48 hours forming a protective layer on your paver bricks and seams
Paver Brick Pressure Cleaning is performed using a pressurized water tank which pumps water through a nozzle onto the surface of the water. The temperature and pressure can be controlled so that the water penetrates the surface of the pavers and lifts up any stains. Additionally, different chemicals can be applied to the surface of the pavers prior to pressure cleaning to help aid in the dissolution process of tougher stains. A test area is always utilized to determine if any of the chemicals will have a negative effect on the pavers prior to being used. A small amount of the sand in between pavers may become dislodged during the pressure-cleaning, and will be replaced once the pavers are allowed to dry
