Crystal Seal HS

  • CrystalSeal HS is a high-solids, solvent-based acrylic sealer developed to protect decorative concrete while significantly deepening surface color and imparting a glossy, wet-look finish. This professional-grade formula enhances texture, boosts color vibrancy, and guards against UV damage, moisture intrusion, and surface wear. CrystalSeal HS is ideal for high-profile architectural surfaces and outdoor hardscapes where richness of finish and durability are top priorities.
