Solvent-based, deeply penetrating primer with consolidation effect on existing coats of paint. For exterior use.

Field of Application

High-quality, transparent special exterior primer for pre-treatment of critical/problematic mineral substrates, as priming coat before applying coats of paint and exterior render. Also suitable for consolidation of sanding, porous renders and concrete surfaces, cement-based Disbocret mortars and fillers/surfacers or substrates where paint has been removed by mechanical means.

The surface of adherent, chalking existing paint coatings is strengthened with Dupa-grund, while non-adherent coats of paint peel off and are easily removable by mechanical means. Do not use the product on ETICS/EWI systems with polystyrene boards and on polystyrene containing renders.
