Kalmatron-Akrilast — cement-polymer coating waterproofing

Cementitious coating waterproofing

The one-component dry mix with a redispersible polymer binder is mixed with water only; no second component is needed. The compound is suitable for bathrooms, pools, foundations and basements: it is applied with a spatula or wide brush onto concrete, brick, screed, moisture-resistant plasterboard and plaster, followed by finishing and tiling. The light grey coating shows watertightness of at least W14, tensile strength of at least 3.0 MPa and bond to concrete of at least 1.5 MPa.
