Technical leaflet VARNISH-PU 2KW is a transparent, aliphatic, water-based, 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 radiation and weather conditions (rain, frost). • Resistance to detergents, oils, sea water, alkalis. • Vapor permeability. • Resistance to pedestrian and light vehicle traffic. • Ideal for indoor applications in poorly ventilated spaces, as it is water-based and thus almost odorless. Certified with the CE marking as a coating for surface protection of concrete, according to EN 1504-2. VARNISH-PU 2KW is suitable for waterproofing and protecting: • Decorative cement mortars. • Concrete. • Natural stone. • Wood. • Epoxy paints (e.g. if the final surface is desired to be mat). 2.

2. Mixing Components A (resin) and B (hardener) are packed in two separate containers, in the correct, predetermined mixing ratio by weight. The whole quantity of component B is added into component A under continuous stirring. The two components should then be mixed for about 2-3 minutes with a low-speed mixer (300 rpm). It is important to stir the mixture thoroughly near the sides and bottom of the container, to achieve uniform dispersion of the hardener. Subsequently, water may be added under continuous stirring (up to 10% by weight, depending on the desired workability). The water must...
