High Grade Clay Paint

Auro 331 is a new clay paint for living spaces. It is splash water resistant and therefore well suited for application in kitchens and bathrooms. The biogenic binding agent REPLEBIN®* guarantees professional product features, e.g. a good abrasion resistance (class 3, DIN 53778) and opacity (class 2).

AURO High-grade Natural Clay paint is the first ready-to-use clay paint on the market that has no preservatives at all. It is MI and BI free.

Wonderfully creamy white matt finish.
Thanks to Auro's ecological choice of raw materials and compliance with the strict AgBB criteria on emissions (a German evaluation scheme for VOC emission from construction products), this product is a special recommendation for use in living areas. It has a moisture regulating effect and is open to water vapour diffusion and highly breathable. It is especially recommended for use in sleeping rooms because the paint can store the humidity emitted during the night and release it again therefore improving air quality in the bedroom.
Roller application produces a fine and smooth coating because the light clay used in the product is not granular or sandy.
Thick coverage with great covering power and a very low tendency to drip or spatter. Suitable for most interior wall surfaces.
