Product Description

American Clay earth plaster is a unique blend of clays, aggregates, and natural pigments ideally suited for interior walls and ceilings in residential, commercial institutional, hospitality, and heal/spa applications.

A More Cost Effective Choice

Compared to other unique wall covering materials, earth plaster saves labor, is reusable, stores forever and has a direct impact on energy consumption.

Three Unique Finishes

Our three plasters each offer their own distinct finishes and textures while achieving superior bond and durability.

  • LOMA™: Our original smooth finish, creates a soft, even finish that can be worked to a matte look or an almost unlimited number of textures.
  • PORCELINA™: Super-smooth for a more polished appearance, PORCELINA creates a harder Venetian veneer at a fraction of the cost. Its remarkable character is achieved by using kaolin – no acrylic, lime or cement necessary.
  • MARITTIMO™: Featuring a seashell aggregate, MARITTIMO produces a uniquely smooth yet faceted effect – a natural sheen with additional hardness.

Apply With Ease

American Clay with the addition of Mud Glue™ will bond directly to a variety of substrates including drywall, masonry, plasterboard, cement coatings, gypsum and lime based plasters and existing painted walls. Mud Glue provides increased durability and impart resistance when used in the top coat. Proper wall preparation is required for various substrates. And to make your application process even easier, American Clay offers a selection of compatible products including Sanded Primer, Penetrating Sealer, Glass Sealer, and Dura-Mix.
