Topic tags/keywords: question

I’ve just finished my first piece of outdoor furniture and promptly put the wrong finish on it, Tongue Oil. I ran out of what I had (no mention of interior use only on the label) and bought a different brand to finish. The second brand label clearly said “indoor use” so I figured I’d put another product on top of the Tongue Oil. I tested Spar Urethane over Tongue Oil on a scrap board and it went on fine. I’ve since learned that tongue oil will repel urethanes. Great! I’ve gone from bad to worse.

So my questions are:

1. Since the urethane currently doesn’t show any sign of being repelled, will this happen over time or have I dodged a bullet?

2. Is there any solution short of stripping the wood?

Thanks in advance!

Try using dewaxed shelac as a barier between dis-similar finishes. BTW, one of the problems with clear finishes on wood exposed to sunlight is that the UV rays go through the finish and attack the wood. Then the finish peels. It takes a couple of years.
That is why an oil finish is often the best for use on outdoor furniture exposed to lots of sunlight.

Yes I would put on dewaxed shellac. But you’ve already put on urethane so It’s too late on that.
