Permalac Original is a protective, water-clear, fast-drying, solvent-based lacquer coating. It is a direct-to-substrate (DTS) coating, meaning it is designed to be applied to a myriad of surfaces directly without the use of a primer. Permalac’s state-of-the-art UV and corrosion inhibitors, as well as wide-ranging temperature stabilizers, assure endurance in the harshest conditions ranging from arctic freezing to desert heat, to beachfront salt air to acid rain. You can apply it to most metal, wood, or stone surfaces whether the surfaces are bare or painted. Permalac can behave as both a sealer (in case you decide to paint over it) or as a highly resistant topcoat, providing protection from all types of environmental corrosives. It has outstanding adhesion to a variety of substrates, including patinated and polished metals (copper, brass, bronze, steel, aluminum, zinc, etc.), hard woods, fiberglass, and masonry or stone products in both land and marine applications. On metals, Permalac is flexible and does not separate when the metal is bent. It also provides absolute protection for circuit breakers and other electrical components from molds and mildew, helping to avoid short-circuiting and other disruptive difficulties. Permalac can be sprayed or brushed on and, can be used in interior or exterior applications. It is available in either satin or matte sheens. Coverage is 400 square feet per gallon in a single coat.
