Most building substrates (some require a suitable primer), including plasterboard and other conventional and eco-walling substrates.

Description

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, allow 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.

Features and benefits:

  • 100% natural.
  • Available in classic and custom finishes.
  • Non-caustic.
  • No requirement for painting.
  • Passive regulator of humidity and temperature.
  • Recyclable.
  • Non-toxic, no volatile organic compounds (VOCs), no off-gassing.
  • Helps maintain indoor moisture levels between 40–60%, the level recommended by Allergy UK to help prevent respiratory problems and illness.
  • Helps mitigate the effects of indoor ozone and formaldehyde.
  • Suitable for insulating and breathable render carrying boards, in rooms such as kitchens and bathrooms (but no areas in direct contact with water such as splashbacks).

Application:

Most building substrates (some require a suitable primer), including plasterboard and other conventional and eco-walling substrates.
