MastaLite Joint Compound Siniat

MastaLite is a premixed all purpose, lightweight jointing compound that is suitable for bedding tape, second and final coating of plasterboard joints, angles and fastener heads. It is a lightweight compound and is ideal for use with mechanical tools. MastaLite is the perfect solution for finishing plasterboard joints when superior coverage and finish are desired for any commercial or residential project.

MastaLite is recommended for finishing Stratopanel joints after applying Uniflott for easy sanding and smooth finish.

With exceptional body and ease of trowelling for both hand and mechanical tools, MastaLite will maintain body when mixed or worked on the hawk. It provides the perfect amount of time to obtain good thin edges when feathering as it does not dry out too fast. MastaLite has a very light colour when applied, drying to a clean white professional finish.
