American Clay

American Clay Natural Earth Plasters bring the appealing finishes of Nature to your Home, Office, School, Business, anywhere you want to add healthful beauty to your interior walls and ceilings. Manufactured in and using materials from the United States, American Clay uses natural clays, recycled and reclaimed aggregates, and vibrant natural pigments in each of our three beautiful finishes: LOMA, PORCELINA, and MARITTIMO.

Loma provides the unique clay texture to the final surface of your walls, while also providing the basecoat for our other two dramatic finishes: Porcelina and Marittimo.

Porcelina gives your surface a satin smooth finish, which is highly sought after in the Venetian Plasters of Italy.

Maritimo is the newest finish - born from the Mediterranean tradition of crushed shells mixed with clays and color to create a magnificent wax-like patina.

Their signature Destination Colors were created to combine the remarkable properties of our finishes with the rich hues of nature. Enjoy an adventure in light and color.

American Clay Earth Plasters surround your family or workplace with the warm beauty of soothing texture and rich color - far exceeding the interior surfaces produced by traditional paint, stucco, or other finishes. Earth Plasters are non-dusting, mold and fade resistant, repairable and moisture controlling.

Natural Earth Plasters from American Clay are easily adapted to Do-It-Yourself projects. The Traditional and Classic method of creating American Clay surfaces is non-toxic, easy to repair, easily reworked, and exciting to learn.

American Clay Earth Plaster is a practical, environmentally friendly alternative to cement, gypsum, acrylic, and lime plasters. It is compatible with the “breatheable” construction recommended for both historic and new buildings.

American Clay Earth Plasters will cover most wall surfaces. However, we do not recommend application on oriented strand board (OSB), tongue and grooved paneling, and other materials prone to expansion and contraction with changes in temperature and moisture. Our plasters are also not recommended as a finish over ceramic tile.

Our plasters have a far longer working time than other plasters—up to several days if you need it—so you can take your time and work with confidence that the surface won’t “set” before you’ve achieved just the finish you want. Besides, there’s no waste. You can reuse any excess plaster—even after you’ve mixed it and it’s dried. Just break it up and rehydrate it. Our plasters can be troweled on like traditional plasters, but you can also spray them on with a drywall hopper.
