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.
