StainShield-15™ Sealer Technology

There are many sealers on the market to protect granite surfaces from staining and to reduce porosity. StainShield-15™ uses technology that anchors the sealer to the stone surface matrix through a chemical reaction. This means that the sealer and the surface will have a strong bond requiring high energy to break down. The sealing of the natural stone comes from changing the capillarity structure of the surface which changes the surface tension.

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.

The surface interaction of anchoring by chemical reaction marks the difference between the long-term protection of StainShield-15™ and other standard sealers that only provide short-term protection.
