What is the difference between StainShield-15™ and common granite sealers?
Traditional sealers anchor to the stone surface through electrostatic or Van Der Waals forces that are not stable and relatively weak compared to normal chemical bonds. This means the energy required to break down this interaction is much lower than the bonding force of a chemical reaction. The sealing function for these common sealers comes from closing or reducing the porosity by placing a polymeric layer of material.
