RSA Patch Fine is to be used to fill minor imperfections of 1.5mm or less that may appear in concrete and masonry substrates. This product is typically used to set and ‘feather out’ in-situ formwork joints and can also be used to fill blow holes. It is to be used prior to the application of a roll-on texture or spray-on finishes and in-situ formwork.
Patch Fine is easily sanded and creates an excellent base coat ready for priming and protective coatings. It can be used as an overcoat to Patch Coarse and Patch Smooth to produce a finer finish to the substrate.
