STAIN-PROOF Penetrating Sealer Technology

STAIN-PROOF impregnating sealer technology is different.


The special penetrating sealer molecules are hundreds of times smaller than competitor stone sealers and penetrate much deeper into the pore structure, even dense natural stones like granite. Inside the pores our special sealing molecules bond permanently by chemical reactions , creating a substantial, deep oil and water-repellent barrier.

The deeper STAIN-PROOF barrier, not only provides great surface stain protection, but also protection against more serious common types of damage cause by water ingress (penetration), including efflorescence, salt spalling, freeze-thaw spalling, and picture framing.


STAIN-PROOF impregnators provide superior protection.

  • Super oil and water repellence = superior stain protection.
  • Deeper penetration and permanent bonding = permanent PLUS premium protection from efflorescence, salt spalling, freeze-thaw spalling and picture framing.
  • For indoor and outdoor use on residential and commercial projects on floors, patios, entertaining areas, facades, cladding, pool surrounds and walls.
  • The penetrating sealers even stand up to commercial cleaning techniques e.g. high pressure hosing and maintain the slip resistance of the surface.
  • Written 5, 15, 25 and 30 year performance warranties are available when our impregnating sealers are applied by a STAIN-PROOF Accredited Applicator.
