A solvent-based synthetic-resin primer, for preparation of porous substrates such as masonry and concrete to optimise the bond of cold-setting adhesive tapes, and cold self-adhesive roof underlays. Penetrates up to 3mm into the surface. Fast curing. Particularly recommended in winter! Yield: Approx. 5 m²/litre Working temperature: from – 10 °C.
UNI Primer is a quality, solvent-based synthetic-resin primer for preparation of the substrate to optimize the adhesive properties of cold-setting adhesive tapes, cold self-adhesive roof underlays etc. It can be used on all absorbent mineral substrates e.g. concrete, bricks, wood, etc. Advantages compared with bitumen primer: temperature resistance up to 100°C and can also be used at -10°C; it penetrates 3mm into the surface and forms a firm bond between material and adhesive; quick drying: in summer approx. 15 min., in winter 30- 45 min.
