What Exactly is Permalac

That’s one of our favorite questions to address. There are so many definitions floating around on the Internet that it’s best if heard direct from the source.
Permalac is an air-dry lacquer and coating for metal, stone, and wood. It’s primarily designed for protecting exterior surfaces like bronze, copper, steel, silver, and aluminum. Additionally, Permalac has been used in many other applications such as stone surfaces like masonry, stone monuments, terracotta, concrete surfaces such as floors, even antique interior wooden chairs. Painted or unpainted wood substrates are easily protected with Permalac.

From our Website:

Unlike most other protective clear coatings Permalac can be applied to most surfaces directly without the use of a primer. That is why it’s called a Direct to Substrate (DTS) coating. You can apply Permalac to most metal, wood, or stone surfaces whether the surfaces are bare or painted on.

Permalac protective clear coatings can be sprayed or brushed on. It air dries to the touch in less than 5 minutes and dries to a virtually indestructible finish in less than an hour. When retreatment is indicated, Permalac can be easily and completely removed by wiping the surface down with acetone.

Once Permalac protection has been applied, you can count on many years of service before re-coating is required.”


Most failure of clear coatings over copper, brass, bronze and steel are not due to the failure of the coatings itself but rather to progressive staining and tarnishing of the metal underneath

Permalac inhibits UV and corrosion of properly prepared surfaces. Typically exterior metals like copper gutters might develop a patina beneath the lacquer’s surface, not as a result of Permalac failing.

Permalac Do’s

  • Do spray Permalac or brush on properly prepared surfaces
  • Do ensure that surfaces are thoroughly cleaned and dry prior to application
  • Do apply Permalac directly on prepared surfaces without the need for a primer

  • Do expect Permalac to be effective against Ultra-Violet Light, Salt (and salt air), and acid rain.
  • Do spray large surfaces for speed of production if needed
  • Do use Permalac on jewelry, dipped is the best outcome but it can be sprayed or brushed
  • Do immediately wash affected skin to be cleaned with soap and water
