Smooth Lime Plaster

By Unearthed Paints


Unearthed Plasters provide a unique and elegant natural wall finish.  Smooth Lime Plaster is a thin top-coat plaster that is typically applied in thicknesses of 1 to 2 mm (about 1/32" to 1/16").  Maximum thickness per layer is 2mm (1/16" inch).  In most cases, only one layer is required.  It may be directly applied over drywall. Unearthed Mix-Ins can be added to the plaster to customize the look. Unearthed Lime Plasters are ideal for humid rooms such as bathrooms, kitchens, and basements or in humid climates because the naturally high alkalinity of lime inhibits fungus and bacteria growth.  Made with natural, nontoxic ingredients and 100% VOC-free.
