Product Description

Keim Concretal-Lasur is a sol-silicate one-component mineral colour wash for the protection of concrete surfaces where the concrete surface texture is required to be visible and any colour differences need concealing.

Please note, you will require Keim Concretal Dilution for this product at a ratio of 3 parts Dilution to 1 part Lasur. See product data sheet for guidelines.

Keim Concretal-Lasur is ideal for both interior and exterior concrete surfaces, providing a colour wash or semi-transparent finish which gives an even colour finish, concealing any colour variations caused by stains and repairs whilst retaining the appearance of a concrete surface texture. Keim Concretal-Lasur is free from biocides, will resist mould and fungal growth and is weather resistant. Keim Concretal-Lasur is water repellent and vapour permeable.

Best Uses

A sol-silicate mineral paint system, Keim Concretal-Lasur is suitable for use on concrete surfaces to provide a colour wash or semi transparent finish. Offers water repellency, vapour permeability and forms a chemical crystalline bond with the substrate.
