Exempt Solvent-Based, Pigmented Cure & Seal for Exposed Aggregate Concrete

BROWNTONE CS 350 is an exempt solvent-based acrylic polymer blend that cures, seals, and enhances the appearance of exposed aggregate concrete surfaces. BROWNTONE CS 350 is specially formulated with earth-toned pigments that highlight the natural color of the aggregate, making exposed aggregate surfaces look more even in color and richer in appearance. BROWNTONE CS 350 also provides protection against the damaging effects of traffic, weather, and de-icing salts. Although especially formulated for exposed aggregate concrete, BROWNTONE CS 350 can be used on any concrete surfaces - new or old - where a translucent brown tint is desired.
