American Clay Penetrating Sealer

Used as a low-sheen sealer for American Clay Earth Plasters or as a pre-seal for American Clay Gloss Sealer, this penetrating sealer is a low-VOC (25g/litre) product that increases the durability and water resistance of the final plaster. A single coat imparts a low-sheen. Two to three coats produce a hard, semi-gloss finish that makes the surface easier to clean and more water-resistant. You can use it on surfaces subject to occasional moisture, such as walls behind sinks and around bathtubs, but not on walls in constant contact with direct water sprays. A slight change in colour may occur with American Clay Penetrating Sealer. We recommend testing a small area on your wall to see the colour change.

Available in 1- and 5-gallon containers.

Coverage: First coat - 150 to 200 square feet per gallon, depending on the surface texture and porosity. Subsequent coats - 250 to 350 square feet per gallon.

The Healthiest Guarantee
American Clay Earth Plasters are composed of pure clays and aggregates. The colours are derived from natural, non-toxic oxides and ochre mineral pigments. The only other ingredient is a natural mineral anti-molding agent called borax. Most chemically sensitive people can tolerate the borax.

* American Clay is not recommended for use on strand board (OSB), tongue and grooved paneling or ceramic tile.
