A solvent-free, water-borne hybrid polyurethane concrete primer.

Product Features

• Due to low viscosity Fontefloor PU Cem Primer penetrates well into substrate. • Adheres well to concrete and secures the adhesion of the subsequent layer. Adhesion to concrete is 2.7 N/mm². • Used as a primer in Fontefloor PU Cem systems.




Under cover and free of the ground, in dry conditions above +5°C and below +25°C. This is particularly important for the part C. Protect from frost even during transport.

Application Conditions

The relative humidity of the concrete should not exceed 97%. Residual moisture content should be below 4 weight-%. The temperature of the ambient air, surface or coating should not fall below +15ºC during application or drying. Relative humidity of air should not exceed 80%.

Surface preparation

Always remove all grease, oil, and other impurities with Maalipesu detergent before grinding. Remove laitance or old peeling paint layers by power grinding, milling, or vacuum grit blasting. Choose the method best suited for the premises. Clean out pot holes removing all loose or brittle material. Open cracks with e.g. an abrasive tool. After mechanical pre-treatment remove all loose material and dust carefully with a vacuum cleaner. The substrate must have a tensile strength above 1.5 MPa. For application on cementitious leveling screed: check compatibility with the leveling screed manufacturer.

Painting Cleaning of tools

Cleaning of equipment with Thinner 1061. Equipment should be cleaned immediately after use before the primer has dried.
