Looking to restore your pavers on your driveway, walkway, stoops, or backyard and pool patios, Gappsi provides cleaning & sealing of paving stones for both nassau & suffolk county long island, NY. In the following video you can view a step by step process of cleaning & sealing paving stones. Starting with pressure washing of pavers with high volume low pressure hot water, this cleans and removes dirt & grime that has collected between the joints throughout the years, preparing the surface of the pavers to be sealed. The next step is to refill the joints with polymeric sand and vibrate with a specialized machine, which petrifies when comes into contact with water, which we mist with a garden hose. Next we apply a urethane based sealer. This product is specially formulated to never yellow, fade or peel from pavers. The special sealer gives the stone colors a deeper tone but not a shiny look. We provide sealer installation services as well as retail, where you can buy our paver sealer to apply yourself.
