SB-6400 Wet Look Hybrid Sealer is a unique water-based hybrid blend of silane/siloxane and proprietary polymers that chemically bond to the surface and repel both water and oil. It can be used indoors and outdoors, on old and new, horizontal or vertical surfaces. SB-6400 can be applied immediately after most surface installations, as it is breathable and will not trap naturally occurring moisture or efflorescence. On new concrete, SB-6400 should be applied once concrete is fully cured (30 days after installation). SB-6400 will seal and enhance the beauty of new and old surfaces by enriching/darkening surface tone and color contrast with a natural looking matte finish. SB-6400 protects surfaces from water penetration and salt damage from the use of de-icers or exposure to salt air. Due to its superior water repellency, SB-6400 helps to reduce biological growth such as mold, moss and algae. It is non-hazardous and VOC/EPA compliant. SB-6400 has the consistency of water, is milky white when applied and dries transparent with matte finish. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).
