Clay finishing plaster

Clay finishing plaster is used to fill and level the unevenness of the base plastered surface or to achieve a structural finish.

UKU finishing plaster can also be used as a base plaster on surfaces where the thickness of the plaster must remain minimal.

Clay finishing plaster is a universal plaster that is suitable for many different jobs

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 air humidity in the room, accumulates heat, neutralizes electromagnetic pollution, suppresses echo, inhibits the formation of molds and is suitable for allergy sufferers.
