Duro Shine

686 PLUS Sealer

Ultra High-Gloss Sealer

Vibrant High-Gloss Architectural Protection

Duro Shine 686 PLUS is engineered to bring a magnificent glass-like brilliance to stone and tile projects. Powered by an advanced water-based self-crosslinking acrylic and polyurethane blend, it forms a heavy, resilient protective shield that delivers maximum wet-look reflection with outstanding chemical and scratch resistance.

Modern Lacquer Alternative: 686 PLUS is a direct upgrade to traditional oil-based lacquers. It provides the deep, dramatic wet shine you want for walkways and indoor floors without yellowing, darkening over time, or releasing harsh chemical odors.

While inferior gloss sealers use cheap wax flatteners that trap dirt and leave coatings looking cloudy after a second application, 646 and 686 PLUS formulas go on perfectly level across multiple layers. The open-pore crosslinking film maintains crucial breathability, allowing moisture vapor and hydrostatic pressure to pass safely through the stone from the earth without causing the coating to blister or peel away.
