Pur Concrete strengthener

Pur Concrete strengthener


Primer to strengthen and impregnate mineral substrates, concrete and cement screeds on walls and floors, e.g. in garages, warehouses and workshops. Particularly suited for priming critical or highly absorbent mineral substrates, subsequently coated with Jansen Aqua 2-component floor sealer, Aqua Methacryl floor sealer, Liquid plastic and Aqua Floor varnish. PUR Concrete strengthener must fully soak into the substrate. Glossy areas will act as a separating layer. Never prime sealed surfaces.
