Level V Wall and Ceiling Primer/Surfacer with M2Tech® is a high quality PVA product applied in a production spray application to create a smooth wall finish that also gives mold resistance. It takes a level 4 finish to a level 5 without the need to skim coat by hand. Level V allows the paint to absorb at the same rate over the entire gypsum surface by sealing the porosity between the joint compound and the wallboard paper surface which provides a uniform finish coat.
