Product Information Sheet:


ROCKBOND RESINTOP PRIMER (RB RTP) is a specially formulated two part, water based, epoxy resin system which consists of a hardener and a base, and is filler free. When the hardener is mixed with the base component, a free flowing epoxy grout is produced which quickly hardens to produce a clear, impermeable, strong bonding, high strength material. The compound is used to seal and strengthen cementitious and brick surfaces, and to bond various construction materials to concrete and steel. The resin is supplied in 4.2kg/4.5 litre packs and has a shelf life of 1 year.
