Prosoco SingleStep WB

SingleStep® WB is a water-based acrylic-silane blend for curing and weatherproofing new concrete in one easy step, inside and out. SingleStep® WB quickly penetrates to form a water-repellent gel in the pores and a semi-glossy film on the surface. This film helps keep concrete moist until it reaches maximum hardness. The cured concrete resists damaging water penetration, salts, and de-icer chemicals. Quick-curing SingleStep® WB beads are water after 24 hours. Water repellency of treated surfaces will increase for up to 72 hours.

Water-Based Acrylic-Silane Cure & Seal for Concrete

Product Description

SingleStep WB is a white, opaque, water-based acrylic-silane blend for curing and weatherproofing new concrete. In a single application, it forms a water-repellent gel in the pores and a semi-glossy film on the surface. This protective layer helps concrete retain moisture during curing and shields the surface from water damage, salt intrusion, and de-icing chemicals. The film begins repelling water within 24 hours, with full repellency developing by 72 hours.
