100% natural clay plaster.
Most building substrates (some require a suitable primer), including plasterboard and other conventional and eco-walling substrates.
Clayworks Clay plasters include blends of unfired clays mixed with minerals and pigments to provide healthy, breathable finishes for internal walls and ceilings.
As well as being 100% natural, the clay plasters are also high performance. The plaster regulates relative humidity, allowing buildings to breathe, and absorb toxins, odours and acoustics. They can also passively regulate temperature.
The product offers a seamless finish, ready mixed in a wide range of naturally pigmented colours and extraordinary textures, from luxurious silkiness to deeply coarse and rustic.
