Womersley’s Wet Clay Undercoat Plaster

Womersley’s Wet Clay Undercoat Plaster is a blend of clay, sand aggregates and hemp straw. Supplied as a wet coarse backing coat. For internal use on masonry, render carrying boards, laths, brick and earth blocks, or strawbales, after they have been primed with Wet Clay Slip.

Clay plasters not only look beautiful but have brilliant eco-credentials for a sustainable and healthy home.  Clay Plasters harden by drying and, as no chemical reaction takes place, they remain workable for a lengthy period and can be reworked with the addition of water.
