Siloxane Based Sealers are Best for Poured Concrete, Brick and all Masonry Surfaces.
Siloxane, not to be confused with Silicone, is a chemical that is used to formulate siloxane based concrete and paver sealers. Siloxane based sealers can be water or solvent based although the water-based blend of siloxane sealers are lower in VOC and more compliant in certain states.
These siloxane sealers are popular among homeowners because they are user friendly and easy to apply. They penetrate into the surface and react to cause a hardened barrier within the substrate pores. They do not stay on top of the surface like other sealers
