American Clay. Adding a clay plaster aesthetic to walls just got easier. With the Up & EZ! binder material, a roll-on application of American Clay plaster interior finishes is now available. The re-emulsifiable and repairable binder can be added to any color-integral American Clay Legacy product to make it a roll-on product and it also serves as a hardener. After rolling on the material with a 1/4-inch nap roller, applicators can use the trowel to create the desired texture. The product eliminates the messy hawk-to-trowel process that can intimidate users not accustomed to working with plaster. 866.404.1634.
