WB Stipple primer grey is novel Environmentally Friendly stipple coating based on a highly alkali resistant binder. Due to the nature of the binder it can be applied directly to dried masonry surfaces where it fulfils both the functions of the primer and the intermediate coating. If applied by block brush it produces a highly filled coarse textured coating. A yellow stipple roller produces a heavier, slightly more pronounced stipple than what is achieved with a lambswool roller. Mostly used on exterior surfaces and internal feature walls.
