In the spring of 2005, Plastering by Nealeigh, Co. introduced a "Green Tree" product, American Clay Plaster System. Slaked lime, marble dust, quartz aggregates, and natural pigments from the earth produce natural finishes that have an iridescence that makes the finishes look richer with the depth of color saturated throughout your project. Superior crack-resistance, and mold and mildew resistance provides a warm, inviting look that can be applied over new or existing drywall as well as any substrate suitable for traditional plastering, at comparative prices.
