Technical leaflet Description VARNISH-PU 2K is a transparent, aliphatic, two-component polyurethane varnish. The membrane it forms is watertight and resistant to UV radiation; it does not turn yellow and has very good mechanical and chemical resistance. It offers the following advantages: • Easy application. • Resistance to UV and weather conditions (rain, frost). • Resistance to detergents, oils, sea water, alkalis. • Vapor permeability. • Resistance to pedestrian traffic and light vehicle traffic. Certified with the CE marking as a coating for surface protection of concrete, according to EN 1504-2. VARNISH-PU 2K is suitable for waterproofing and protecting: • Decorative cement mortars. • Concrete. • Natural stone. • Wood. • Metallic surfaces. • Epoxy paints (e.g. as protection of EPOXyCoaT-S inside swimming pools). It provides resistance to chalking and discoloration, caused by the UV radiation. Viscosity (gloss): Density (A+B satin): Viscosity (satin): Mixing ratio (A:B): Pot life: 2.

Substrate preparation The substrate must be dry, clean, free of grease, loose particles, dust etc.

2. Mixing Components A (resin) and B (hardener) are packed in two separate containers, in the correct predetermined mixing proportion by weight. The whole quantity of component B is added into component A. The two components should be mixed for about 2-3 minutes, using a low-speed mixer (300 rpm). It is important to thoroughly stir the mixture near the sides and bottom of the container, to achieve uniform dispersion of the hardener. It is advised to let it rest for a few minutes after mixing, in order to help entrapped air to escape. 3. Application - Consumption VARNISH-PU 2K is applied by roller...
