American Clay creates a natural plaster product for your walls, ceilings, and even fireplaces. It's a wonderful, environmentally friendly alternative to cement, gypsum, acrylic, and lime plasters. American Clay is made in the USA from American materials including natural clays, recycled and reclaimed aggregates, and vibrant natural pigments. The look is beautiful, textured, earthy, simple, and elegant.
This is probably one of the most eco-friendly options for walls, possibly contributing up to 7 LEED credits. Sheetrock, joint compound, and paint, even if green, will not match the greenness of natural plaster.
There are over 100 color choices in three finishes to choose from — the color palette is beautiful. You may order products on their site, find local dealers, and even find out where to take a class to learn the art of applying plaster, although the site says that application is well within reach of most do-it-yourselfers.
