Unika Colorfill worktop joint sealant for the installation of mitred worktop joints. It is designed to colour match to worktops to create an almost invisible joint. Colorfill worktop joint sealant bonds the joint together, seals against water and domestic detergents, as well as repairing scratches and chips in laminate and melamine surfaces. It is supplied in a handy 25g tube, which is enough for one worktop joint.
