Honed and filled finishes are not recommended for Florida Keystone due to the large natural voids and holes characteristic of the material. Saw cut unfilled is the optimal finish for this stone.

Other thicknesses available up to 20" thick by Special Order.

Sealing Options

Classic Premium Keystone offers two distinct aesthetics depending on your sealing choice. With no sealer, the stone will gradually develop a beautiful natural patina over time, achieving the sought-after "Old Castle Look" with a weathered, organic appearance.

If you prefer to maintain the stone's original crisp white color, apply a high-quality impregnating stone sealer and reapply regularly. A white-enhancing sealer will keep the stone looking clean and bright even after years of exposure.
