The HYDROFLEX joint filler is a plasterboard putty obtained from a selected mixture of gypsum, aggregates and
chemical additives that give the mixture a plastic appearance, easy to use and with low water absorption and excellent adhesion to the substrate.
It is specifically designed to be used in grouting joints between HYDRO plasterboard sheets, for grouting fixing screw heads, for repairing damaged small HYDRO plaster or plasterboard parts. Thanks to its excellent adhesion to the substrate it can also be used on particularly difficult surfaces such as slabs with
veil fibre glass surface.
