Some of our most frequently asked questions.
Permalac will not yellow from sunlight.
Yes, Permalac can be applied over painted surfaces as long as the paint is acrylic, solvent-based or latex-based for the most part. Permalac cannot go over enamels or oil-based paints due to chemical incompatibility.
Permalac provides exceptional protection against sunlight, moisture, and salt.
Permalac is a very versatile coating. It can be applied to metal, masonry, and wood. It can also be applied over paints (acrylic, latex, and solvent) and patinas. Substrates need to be clean and dry before applying Permalac.
Permalac should be applied at temperatures above 50°F. In hot conditions, a slow thinner such as #69 should be used.
Permalac takes between 24-72 hours to fully cure. We recommend waiting the full 72 hours before any substrates coated with Permalac are installed or transported.
Permalac typically lasts up to 10 years on indoor structures and approximate 3-5 years on outdoor structures with a single application (3 coats minimum indoors and 4 coats minimum outdoors). Our formula has not changed, though the design of our cans has. Permalac spray cans have a shelf life of 3 years from the date of manufacture, after which they should be safely discarded. Quarts, gallons and larger sizes have a shelf life of 2 years from the date of manufacture. You should have the same lacquer, but all of our products now come with a specific designation as to which finish it is.
A second coat can be applied as soon as the first coat is touch dry, usually in 15 minutes.
A single gallon of Permalac will cover 400 square feet.
Permalac works best when a minimum of 3 coats is applied for indoor applications or 4 coats for outdoor applications. It is best to stick to these numbers when possible to assure good product performance.
For outdoor applications, the Permalac lifespan averages out to 3-5 years. For indoor applications, Permalac lifespan is about 8-10 years. It is recommended to perform normal maintenance and reapplication every 3-5 years to keep your substrate protected!
Surfaces should be free of grease, dust, and moisture. Make sure to keep the surface of your substrate degreased and dry by wiping it down with lacquer thinner or acetone (only when applicable).
Permalac can be sprayed, brushed on, or dipped. It is available in convenient spray cans for smaller jobs. Cans are available in many different sizes. See our store for all of the options!
Fresh Permalac can be applied over old Permalac, even years later.
Permalac clear coat is water clear and will not alter the color of a substrate. Applied over polished metal it is very nearly invisible, over metal patina it will cause a slight darkening.
