When choosing a paver sealer is best to understand that not all acrylics are created equal. There are many paver sealers that contain inferior acrylics that will blush to turn white in color. Notably Behr Wet Look Sealer and H&C Water-based sealer. Best for a paver sealer is one that does not seal the surface 100% but rather breathes. These sealers are less prone to trapping moisture, which may lead to the dreaded white haze. Most high-quality water-based sealers will not blush as they are thinner in viscosity. Solvent-based sealers containing a solid acrylic will have a tendency to blush/turn white. If you choose a solvent-based sealer, make sure that it is a “Styrene” acrylic as these have tiny pinholes that allow the coating to breathe.
