American Clay Black Soap Finish

Designed primarily for use with American Clay Porcelina, this black soap finish is a gelatinous castile soap infused with potash that produces an amazingly rich colour with a soft patina, a surface thatŐs not only stunning but also easily repairable.

Available in 500 gram (about 1 pint) and 500 kilogram (about 1 gallon) containers.

Coverage: 1000 to 1750 square feet per gallon over American Clay Porcelina.


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.
