Blue Water Power Washing is trained and a Certified Applicator from Deco Product s to clean, sand and seal. We follow their recommended process when cleaning to prepare for sanding and sealing. The process takes multiple steps to achieve a professional result. -First we start by applying an algaecide to kill all organic growth to make cleaning the pavers with higher pressure easier. -Next step is to use a high pressure turbo nozzle tip from a safe distance to blow out all the old sand in between the pavers to get rid of any unwanted moss and weeds but without damage to the stones. -We then follow up with a professional grade surface cleaner to ensure a uniform clean on all the paver stones. -Next is to apply a neutralizer to rebalance the pH of the stones, followed by more heavy rinsing -Our preferred method is dry sanding, so after 24-72hrs of cleaning the stones we will return to complete the sanding and sealing -We use ASTM-C144 joint sand. We broom in the sand (color of customer choice) and follow up with a leaf blower to get an excess sand out and make sure there is about 1/8' below the chamfer of the stone. -After all sand has been replaced and leveled, we use a joint stabilizing sealer to protect the pavers from moisture getting in and stabilizing the joints by creating a rock hard seal that won't allow the pavers to move due to natural erosion. This process should be completed every year or two to maintain the integrity of an outdoor paver area. However yearly clean and seals are much less expensive then having to relevel a whole paver area after years of erosion have washed away sand creating a ungulated area
