Stopaq® Repair Filler is a unique, low-temperature and cold-applied malleable compound. It is intended to be used as a moulding and filling compound for static cracks, voids, joints, crevices, penetrations, and levelling of irregular surfaces, to form a barrier against water ingress. It adheres to wet or dry surfaces of concrete, brick, metal, and various other types of substrates and requires only minimum surface preparation.
