There is a chance that after a few weeks or months pass, a white haze may appear on the surface of the pavers. This is known as efflorescence. It may appear randomly or in certain areas and will be more pronounced on dark colored pavers. The white haze may give the impression that the color of the pavers is fading. When wet, the white disappears, and the color of the pavers is enhanced. When they dry, the white haze reappears.
Paver sealant is an important maintenance tool to keep paver patios, walkways, driveways and pool decks looking as beautiful as they day they were installed.
Concrete is porous and will absorb stains if not sealed. Sealants can also protect paver color from fading.
