Can Permalac Be Used on Wood?

What Is Permalac?

• Permalac is a durable lacquer coating that is applied to materials and air dried for a tough and long-lasting finish. Permalac contains UV-resistant and anti-corrosion ingredients that make it a good choice for materials that remain outdoors. The coating can resist damage from salt spray and acid rain as well, according to the Permalac website. It is available in gloss and satin finishes. Permalac can be purchased in 12-ounce spray cans, quarts, 1- and 5-gallon cans, and 55-gallon drums. Permalac also is available in a formula that contains low volatile organic compounds for those who prefer a less hazardous, more environmentally friendly material.

Permalac Uses

• Permalac is used for many products and purposes. In marine environments, Permalac provides protection against the harsh effects of intense sunlight and salt spray on light fixtures, decorative brass objects and windshield wipers. It also can be used to protect architectural designs, outdoor art objects and other items. On wood items, Permalac provides protection against UV rays, which can dry and fade materials, as well as providing a tough lacquer finish that resists moisture.

Using Permalac on Wood

• Permalac is applied to wood items much as other lacquer finishes. The surface must be clean, dry and free of other varnish or lacquer coatings. Remove all sanding grit and chemical residues from stripping products. Permalac, like other lacquers, must be used in a well-ventilated area. Wearing a respiratory mask and goggles is recommended to prevent eye, throat and lung irritation. Permalac is dry to the touch in 5 minutes and should be allowed to dry overnight for full curing.

Lacquer Problems

• Permalac can be applied to wood as a spray or with a brush. Like all lacquer products, certain environmental conditions can create problems with the lacquer finish. “Blushing,” a cloudy appearance on the lacquer that forms from moisture condensation, can be avoided by applying the product only when the humidity is low. Blistering and bubbling of the surface can occur when the temperature of the item is too high. Avoid exposing the the piece to direct sunlight while wet. Oils left on the surface of the wood can cause “fish eye”-shaped dimpling on the surface. This problem can be prevented by cleaning the wood surface carefully before attempting to apply Permalac lacquer. Dust in the work area can cause a gritty look under the lacquer. Apply Permalac immediately on entering wood areas before the shop dust becomes airborne, according to the WoodCentral website.
