Cast Stone

TSSPRO SEALANT PRODUCTS FOR CAST (MAN-MADE) STONE

CAST STONE: Cast stone is a concrete masonry form of artificial stone which simulates natural-cut stone. Cast stone can be made from white and/or grey cement, manufactured or natural sands, crushed stone or natural gravels, and may be colored with mineral coloring pigments. Cast stone can be seen in tiles/pavers, columns, cast stone veneers, balustrades, window and door surrounds, many forms of fountains, statues, lawn ornaments, etc. Cast stone is made from concrete and is very porous; it should be sealed to preserve the appearance and prevent deterioration.

Considerations for choosing a sealer: The following are all factors for selecting a sealer. The sealer descriptions below will mention which attributes they have to help in your selection; color enhancing/color change, adding a wet look, minimizing cooking area stains, salt-water erosion resistance, efflorescence resistance, preventing oil (cooking/motor) stains, preventing discoloring mold/algae, preventing deterioration/flaking, adding slip resistance, VOC compliance, general stain resistance, general protection.

Coverage, Number of Coats: Cast Stone/Artificial stone is porous and will absorb sealant; generally, two coats are recommended. Coverage will vary with the sealer selected but will be from 175 sq ft / gallon to 200 sq ft / gallon. The second coat will generally get greater coverage.
