HS 300 is a Premium Acrylic Sealer
HS 300 is a premium, high performance, single-component silane, acrylic 30% solids, 600 g/L, sealer designed for SureCrete overlays or other cement-based products. As with most acrylics it is vapor permeable and readily applies outside. However, HS 300 is specially formulated for extreme climates. The unique silane formulation creates the nano-sealer technology that deeply penetrates and reacts internally with cement, slowing moisture migration and efflorescence and intensifying bond capacity. Even in warmer climates HS 300’s slower evaporating solvents will not “cotton candy” before the applicator can finish a tight, smooth surface. A single coat application will provide a UV shield, enhance the beauty, and protect the surface of driveways, garage floors, patios, walkways, pool decks, and stucco.
