MSA Varnish with UVLS (Gloss, Satin, Matte) is a Mineral Spirit based Acrylic resin system that forms a tougher, less permeable film than water­borne acrylic varnishes and can be applied to acrylic, oil and alkyd painted surfaces. It reduces dirt penetration and surface marring, offering an ex­treme­ly level film with less foam and fewer pin­holes. Available in Gloss, Satin and Matte, it is removable with Mineral Spirits after drying and is recommended for interior or exterior use. Not for use by children.
