MSA (Mineral Spirit Acrylic) 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.
