Tenax Proseal is a solvent-based, oil proof and waterproof penetrating sealer used for in-depth protection of granite, marble, limestone, sandstone and terracotta. It is generally recommended for quartz-based materials and stones containing a mix of silicates and carbonates. The product is suitable for both indoor and outdoor applications and performs well on polished, honed, sandblasted and flamed surfaces. It provides an average coverage of 20 to 30 square metres per litre depending on the surface.
