SB-4400 PERMA-SEAL™ Invisible Penetrating Sealer is a penetrating, breathable silane/siloxane blend solvent based sealer that protects horizontal and vertical surfaces from water penetration and salt damage from the use of de-icers or exposure to salt air. SB-4400 has the consistency of water and is clear in appearance when applied and dries clear with an invisible finish. Some surfaces may darken slightly. It can be used indoors (with proper ventilation) and outdoors on both new and old surfaces. SB-4400 can be applied immediately, as its unmatched breathability will not trap efflorescence. On new concrete, SB-4400 should be applied once concrete is fully cured (30 days after installation). SB-4400 requires two coats. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).
Ideal for horizontal and vertical surfaces including concrete, concrete and clay pavers, grout, unglazed tile and terra cotta. Suitable for cultured and natural stone containing quartz or other silicas. Not recommended for granite, marble, limestone, slate, agglomerate tiles and surfaces with a high gloss finish as they do not absorb the sealer.
A test area is always recommended to determine product suitability and compatibility with your specific surface before use and also if desired results are achievable. SB-4400 may slightly darken some surfaces. Due to the inherent variability of natural stone and clay products, long term performance may vary. Please consult with us prior to sealing if there are concerns.

Per gallon. Two coats applied wet-on-wet at right angles to first coat. Use approximately two thirds of the estimated amount on the first coat and one third on the second, ensuring saturation. Actual coverage may vary depending on the type, age, condition, porosity of the surface, application method and other local conditions such as temperature.
