Detailed Product Description

UPA Base Coat 60 is a plaster-based adhesive used in the jointing of plasterboard. Joints are bedded in Base Coat 60 with tape and then a second coating is applied. Joints are then finished with topping of a finishing coat and smoothly sanded before painting. For best results, UPA recommends the use of Base Coat with all other plaster cement and adhesive products available within the UPA product range.
