Will sunlight cause Permalac to yellow?2018-07-06T19:24:12+00:00

Will Permalac work on painted surfaces?2021-05-18T14:49:43+00:00

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.

Why am I noticing white spots when spraying Permalac?2023-04-02T18:20:57+00:00

There are a few things that can cause you to see white spots when spraying Permalac. 1) If you are spraying Permalac using an aerosol can, sometimes the matting agent in the formula will not disperse well enough if not shaken properly. Shake the can for a good 1-2 minutes prior to applying the Permalac to fix this issue. If this doesn’t fix it, be sure to check the batch number on the bottom of the can to make sure it hasn’t expired. Also be sure to inspect the can for signs of damage which could also cause this issue. 2) If you are spraying Permalac using a spray gun, make sure to check that stirred the Permalac well and that the solution hasn’t dried up due to having been unused for some time. If this is the case, add some lacquer thinner, acetone, or xylene solvent to reconstitute your formula and dissolve the excess flattening powder back into the solution.

What will Permalac protect against?2018-07-06T19:22:57+00:00

Permalac provides exceptional protection against sunlight, moisture, and salt.

What types of paints and/or coatings is Permalac compatible with?2023-04-11T21:27:33+00:00

Permalac is compatible with acrylic paints and solvent-based paints. This means you can apply Permalac over most types of acrylics and solvent-based coatings without any issues. Permalac is NOT compatible over top of enamels or oil-based paints (many of them at least). Please proceed with caution and test a small area prior to applying the product regardless just to be careful.

What type of surface will Permalac work on?2021-05-18T14:29:44+00:00

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.

What temperature is it safe to apply Permalac?2018-07-06T19:21:57+00:00

Permalac should be applied at temperatures above 50°F. In hot conditions, a slow thinner such as #69 should be used.

What is the cure time for Permalac?2021-05-18T14:31:49+00:00

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.

Is the lacquer formula still the same?2021-05-24T18:02:34+00:00

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.

How soon can I put a second coat on?2018-04-23T20:30:51+00:00

A second coat can be applied as soon as the first coat is touch dry, usually in 15 minutes.

How much of an area will 1 gallon cover?2018-04-23T20:35:30+00:00

A single gallon of Permalac will cover 400 square feet.

How many coats should I put on?2021-05-18T14:44:44+00:00

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.

How long will the average application last?2021-05-18T14:47:08+00:00

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!

How long should Permalac be allowed to lock and seal?2023-04-02T18:15:49+00:00

Allow a minimum of 72 hours prior to installing or exposing the Permalac-coated surface to wear and tear. This will ensure your substrate is fully cured and ready to take on the elements.

How do I prep the surface?2021-05-18T14:53:56+00:00

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).

How do I apply Permalac?2021-05-18T14:50:24+00:00

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!

Do I need to remove the first Permalac application before I reapply in years to come?2018-07-06T19:21:21+00:00

Fresh Permalac can be applied over old Permalac, even years later.

Can you see Permalac once it’s applied?2018-07-06T19:25:18+00:00

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.

Can I apply Permalac in sunny locations?2018-07-06T19:23:33+00:00

“The product was infallible. Permalac not only acts as a fungicide that resists mold, it positively repels it. Mold simply can’t and won’t grow on it.”

Aside from protecting the carefully finished metal surface, Permalac has the advantage of being invisible. Unlike other lacquers it doesn’t give architectural coatings a plastic coated appearance and sheen.

“Permalac is extremely easy to use, cures in about 2 hours, and can be sprayed vertically or horizontally without drip formation. Permalac just melts into itself, but even if a texture did develop, we just spray a little more Permalac and we obtain that smooth-as-glass finish our customers require.”
