Description
Overview
Duro Shine 646 Plus is a water-based, film-forming sealer for porous stone and masonry. Its low-gloss satin finish suits projects where a protective surface coating is wanted without the stronger shine of 686 Plus. This listing offers a quart or 1-gallon container.
Features
- Self-crosslinking acrylic and solvent-free polyurethane blend.
- Non-yellowing finish with early water and stain resistance.
- Formulated for hot-tire resistance and a high melting point.
- Breathable coating; can also help stabilize compatible grout and sand joints.

Applications
Use on suitable porous clay tile, concrete, masonry, slate, flamed granite, brick, pavers and other porous stone. The finish is intended to remain at the surface rather than function as an invisible penetrating treatment.
Selection and Use
- Test the actual material first to assess adhesion, appearance and absorption.
- The manufacturer excludes ceramic tile, porcelain tile, polished marble and polished granite from 646/686 coating applications.
- For a higher-shine finish, 686 Plus is the corresponding high-gloss option; do not assume the two products produce the same appearance.
- Hot-tire and stain resistance are product attributes, not guarantees against every exposure. Follow the container directions for preparation, coats and cure before service.
