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.
