As well as being 100% natural, Clayworks clay plasters are also high performance. Regulating relative humidity naturally, they allow buildings to breath while absorbing toxins, odours and sound. They also help to regulate temperature passively and are easily repaired. Application requires the same skills and tools as other wall plasters.
