Densifier, Sealer, and Dust Proofer for Concrete

ULTRASIL LI+ is a water-based lithium silicate solution used to densify, seal and dustproof concrete surfaces. ULTRASIL LI+ penetrates and chemically reacts within the concrete surface, producing extremely hard and dense calcium silicate hydrate (CSH) in the pores. The result is concrete that is more durable, easier to clean, and more resistant to damage from water and mild chemicals. Because the product of the lithium silicate-concrete reaction is formed internally, the protection of ULTRASIL LI+ never peels or flakes off, is unaffected by moisture, and lasts much longer than surface sealers and coatings.
