SMIG C50 is an extra-strong jointing compound combining power with versatility. Use it for plasterboard jointing alongside a variety of other work such as filling, patching and chasing in walls or ceilings.
With no jointing tape required, SMIG C50 is the perfect solution for drywall jointing and filling. It can be used with prefabricated or manually cut plasterboards, and is versatile enough to address cracks, scratches and other imperfections.
C50 boasts a robust compound with a strengthened polymer network, making it more resistant to sanding. When sanded, it descends vertically without lingering or generating significant airborne dust.
