Used as a low-sheen sealer for American Clay Earth Plasters or as a pre-seal for American Clay Gloss Sealer, our 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 to our plasters. 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 color may occur with American Clay Penetrating Sealer. We recommend testing a small area on your wall to see the color change.

PENETRATING SEALER AND GLOSS SEALER: a low voc soy resin/acrylic spray on sealer which provides some increased hardness and sheen to the products. Our sealers also provide additional hardness to the final surface when MUD GLUE is not used. Penetrating Sealer is always used before the Gloss Sealer, which brings a high sheen to the plaster surface
