MastaTape-In Joint Compound Siniat

MastaTape Universal is an air drying compound for bedding tape into recessed edges and butt joints for plasterboard systems. It is also suitable for second coating joints, for internal and external angles as well as fastener heads. MastaTape Universal is ideal for use with mechanical taping and setting tools, minimising time spent cleaning and mixing. Perfect for projects where access to water is limited.

MastaTape Universal is the compound of choice for OPAL plasterboard.

MastaTape Universal saves time by reducing mixing required and minimising the need to clean tools after each gauge. Smooth, creamy and ready to use, MastaTape can be easily adjusted to the desired consistency by electric mixer. It flows freely from mechanical tools for fast tape application, and effortless second coating.
