Clay finishing plaster is used to fill and level the base plastered surface's unevenness and achieve a structural final finish. It can also be used as a base plaster on surfaces where the thickness of the plaster must be kept to a minimum. Suitable for plastering various surfaces in dry interiors.

The clay finishing plaster consists of high-quality clay and sand carefully selected according to a special sieve curve, to which the fiber of the cattail has been added. UKU clay finishing plasters have been tested in accordance with the German clay plaster standard DIN 18947: 2013-08 and belong to the higher strength class S II.

Clay plaster with a sufficient layer thickness (1-2 cm) regulates the humidity in the room, accumulates heat, neutralizes electromagnetic pollution, dampens echoes, inhibits the formation of mold and is suitable for allergy sufferers.
