Troubleshooting a Blotchy Tung-Oil-and-Wax Finish
I went to look at them and it came up in conversation that the client's wife had waxed the cabinets between my oilings. With that info, they decided to try stripping the wax on one of them and re-oiling to see if that helped and that did the trick. So maybe it is something with the oil and the beeswax.
From contributor C:
Looks like mold to me. How did he store them? Have him wipe more oil on and call it a day. Why in the world would you make a mess of a finish by making a mix of all the different ingredients?
From contributor P:
It looks like the wax went nuts in the finish. I think it's separated or something and went on unevenly. Personally, I'd not re-oil a piece. If it's done well when it's built, all you ever need to add is wax maybe once a year or two. Maybe have him wipe it with acetone and see if it clears up. Then a light coat of colored wax gently buffed.
From contributor B:
Wipe it down with mineral spirits and wax only, is my idea.
From contributor J:
This finish you describe would have to be put on very thinly over previously finished wood. Tung oil frosts (turns a whitish appearance) if applied too thick, or in a manner similar to a building type finish (wiping varnish). You should be able to have the customer wipe/scrub off the whitish look with mineral spirits or naphtha.
From the original questioner:
The Land Ark finish is from a company in South Carolina of the same name, used primarily on timber frames to keep them from checking. I started using it on pieces that required oil a while ago and have had good luck. My guess is the finish wasn't properly mixed or buffed out afterward. I like the idea of removing the wax and re-oiling, or using colored wax.
