Our first concern is the use of the epoxy. Although you have may had success with this process previously, we do not recommend the use of Enduro-Var with epoxy or any oil based products. Enduro-Var works well on its own or with GFs water based finishes. There is a great possibility that future finishes can fail.

Yes! But you must follow ONE simple rule to ensure the best possible finish: the underlying finish must be absolutely dry.

Yes! But you must follow a few simple rules to be sure you achieve the best possible finish.

Enduro-Var sprays beautifully if the gun is absolutely clean and does not have any other finish residue. Proper cleaning with acetone followed with hot water should purge the fluid passage. Enduro-Var itself will not cause gun failure.

Another possibility is the power of the gun. Some of the lower quality guns can overheat causing the product to cure in the gun - they need a rest once in a while if you are using them all day.

Also note that Enduro-Var ADHERES WELL only over WATER STAINS, DYE STAINS, and RAW WOOD.

Interior wood stains are formulated for interior use and do not contain UV absorbers, mold retardants or HALS (Hindered amine light stabilizers used to protect the polymers from the effects of photo-oxidation.) Waterbased interior stains are much more likely to fail.

You could try this look on an exterior door that will not receive a lot of sun, but be prepared for more maintenance than usual. It is not recommended.

Everyone should note that all exterior finishes need to be maintained at some point - MOTHER NATURE wins the longevity war

First, test your surface to get a sense for the color present in the wood. To do this, wipe the surface down with mineral spirits (if you are expecting to use an oil finish) or plain water (if you are expecting to use a water based finish). See the following GF video demonstration for a better understanding of this process.

Next, apply product. Here are two recipes for a lightly stained look:

We recommend waiting 5-6 days to let the finish cure a bit before putting outdoors. The finish will continue to harden for approximately 20-21 days.
