Smith Paints Poly-Seal Gloss (Clear) Waterborne Polyurethane Sealer for Concrete (5 Gallon)

Smith’s Poly-SEAL Gloss (Clear) is a single component, fast drying, waterborne polyurethane polymer fused with a cross-linking acrylic which achieves a tenacious bond to approved substrates, with very good resilience, longevity, U.V. stability and wear.

Smith’s Poly-SEAL may be used as a primer for interior and exterior direct-to-concrete applications prior to Smith’s Poly-WB topcoat, as a seal coat to lock down Vinyl Chip prior for residential garage floor systems, finish for Terrazzo as a replacement for traditional floor wax in addition to a standalone architectural and decorative concrete sealer for concrete overlays, Stucco, pavers and more.
