Universal Bonding Compound is a gypsum-based adhesive for interior fixing of plasterboard with or without insulation. It also allows filling of gaps between boards. This plaster-based powder filler contains calcium carbonate and various additives, resulting in a white mix. It can be used with any type of plasterboard with a paper face, with or without insulation (such as glass wool, rock wool, or polystyrene), as well as with concrete, cement filler, render, cellular concrete, and clay brick.
