by American Clay
American Clay's Add-Mix is added to the plaster to harden the cured coat and increase its durability. This makes it an excellent additive for plasters installed in damage-prone rooms and commercial applications. It is added directly to the plaster while you mix it_substituting it for up to 50% of the water. The degree of hardness in the plaster increases with the concentration of Add-Mix. A slight change in color may occur with American Clay Add-Mix. We recommend testing a small area on your wall to see the color change. Available in 1- and 5-gallon containers. Coverage: Varies with concentration.
