Sandstone Sealer 331 

Sandstone Sealer 331 is specifically formulated to enhance and protect sandstone and porous natural stone surfaces. It dries to a high gloss ‘wet look’ clear finish and provides a smooth washable surface, protecting from stains, spills and reducing the ability of moulds, algae and lichen to discolour the surface. It is a UV stable acrylic solution with excellent optical clarity and is designed to provide many years of service.

If you're sealing around wet ares, eg, a pool or spa, some sealers may become slippery when wet. You may need to add some anti-slip powder to your final coat. Click here to view the anti-slip powder page for more information.
