We have started our 2020 cleaning and sealing season rejuvenating the Gappsi showroom parking lot in Smithtown NY located in Suffolk County on Long Island. We are using hot water on low pressure and surface cleaner to remove dirt and residue of oil and other debris collected in the crevices of the pavers surface. We are also using a rotary wand to loosen the dirt collected in between the joints of the pavers. This is a large parking lot built with Nicolock pavers, and the colors of the paving stones are still very nice even after 15 years of being exposed to the elements and vehicular traffic. Nicolock manufactures high-quality concrete products that withstand the test of time. But as any other concrete products, concrete is corrosive and it weathers when exposed to the elements like the Sun’s heat, the rain and snow, and also to the calcium chloride and ice melters used during freezing times. After completing the cleaning of the entire paver parking lot, we filled the pavers joints with haze-free polymeric sand and vibrated it with a mechanical plate compactors to allow the sand to settle in and completely fill the joints. We spray water on the pavers to allow the sand to get wet, letting the water saturate the sand all the way through the bottom of the joint, and also wash off the pavers surface.
The polymeric sand comes in a few different colors, but most commonly used is beige or gray. It really doesn’t matter what color you use because over time it weathers and it will eventually turn into a brownish-gray color. The polymeric sand is a combination of medium-crushed natural sand, that is combined with color and a polymer component. It is activated when in contact with water to make it glue and eventually harden. This makes better for the pavers’ stability, makes it harder for ants to dig and nest in between the paver joints, and also makes it harder for weeds to grow through.
The next process is the installation of the sealer. We use high-quality urethane-water based sealers, which are environmentally safe and won’t harm plants, pets, or humans. It penetrates the surface of the pavers and creates a coating to protect the pavers from the elements. It also brings out and deepens the colors. Our sealer won’t yellow, and it will create a consistent tone on the pavers during wet and or dry circumstances. We allow the sealer to cure for at least 3 days before driving on it, and depending on the temperature, it could be long for the sealer to totally cure.

Cleaning and sealing limestone driveway pavers in Roslyn NY. Stones were pressure washed and joints filled with polymeric sand, vibrated wit rolling vibratory plates. Gappsi Exclusive sealer was applied to expose the color and details of the limestone pavers surface.
It is important to wait at least a year before sealing concrete pavers from the date of installation. Concrete pavers have to cure and must go through a four-season cycle of weathering. This allows most of the lime from the paver’s surface to come out. After the cleaning and pressure washing process, all the lime from the surface gets removed and the color of the stones gets exposed, this allows the sealer to capture the best of the pavers and preserve it that way. The life of the sealer is contingent to how well it has been applied. Three to five years is recommended by most sealer manufactures, and usually people reseal the driveway and pavers that often. But what’s most important is that pavers are sealed right one time and even though the sheen will go away, or some dust my sit on the surface, the sealer that penetrated the surface of the pavers has created that will be present for many years preventing the pavers from edging.
