Product Description
American Clay Add-Mix hardens the cured plaster coat and increases 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 mi 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.
