  • Breathable – allows water vapor to escape, helping to prevent damaging moisture buildup inside the treated material
  • Suitable for indoor and outdoor use
  • Water-based and low VOC
  • PFOA and PFOS-free

Waterbased Penetrating Sealer Technology

Waterbased Penetrating Sealer is a technological step forward, providing a superior level of protection for a competitive price:

1. Deeper penetration = deeper barrier of protection

Waterbased Penetrating Sealer's sealing molecules are engineered to be much smaller for better penetration, even into dense materials, such as granite.

2. Stronger bonding = longer lasting

Waterbased Penetrating Sealer's smaller molecules wedge themselves better into small nooks and crevices (stronger mechanical bonds). The hydrophylic atoms, which enable the molecules to adhere to the treated surface, are better arrayed for superior adhesion. These 2 factors also give Waterbased Penetrating Sealer a longer lifespan than common penetrating sealers.

3. Superior stain protection

Waterbased Penetrating Sealer's deeper protective barrier stops water traveling right up to the surface where it might cause visible damage. Waterbased Penetrating Sealer's liquid repelling atoms are also arrayed for maximum repellence, providing superior stain protection.
