When mixed with water, KOSTER MF1 forms a white cementitious paint which may be used on interior and exterior applications. After curing, KOSTER MF1 displays its typical matte and cementitious finish. The product is not film forming as with traditional paints, and has very good water vapor permeability. Used inside, it ensures a natural room climate and is algae, mold and fungi inhibiting, even though it does not contain fungicides. KOSTER MF1 should only be applied on crack-free building structures.
