Capstone Sealer

Natural Look with Superior Protection

Use Capstone Sealer for Interior and Exterior Applications

The ideal sealer for ceramic, porcelain, all natural stone, or concrete.

High Performance | Low Sheen | Natural Appearance

CAPSTONE has an organic appearance, providing protection with a natural sheen while also allowing the natural beauty of the stone to show through.

Capstone is designed to work in both interior and exterior environments. Praetorian believes in protecting and enhancing the natural beauty of the surface, rather than changing it. This product has been formulated to provide exceptional durability and is functional on both horizontal AND vertical surfaces. Capstone is the perfect sealer to revitalize your natural stone, porcelain, concrete, and ceramic.

We have designed Capstone to be a high-solids, premier sealer that is created for high traffic areas. These areas often require quick and efficient cleaning times, with Capstone, cleaning becomes a breeze. Applying Capstone is made very easy due to Praetorian’s ability to formulate sealers with mop-on technology. One gallon of Capstone can get you up to 3,400 SF of coverage, depending on the surface.
