Pur Concrete strengthener

Application

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.
