Topic tags/keywords: veneer finish oil blotch mineral spirits

I recently veneered a piece of MDF with mahogany veneer using yellow glue. It glued up fine and I gave it a light Sanding after it was dry. I the wiped the dust off using a clean rag and some white spirits. It looked fine but when it dried I had what looked like some oily blotches on it. Any ideas what could have caused this? Seems crazy.

Thx
Chris

Without seeing a picture, it’s hard to say for sure, but I’d guess that your problem stems from the glue that may have gotten onto the surface when you were doing your glue up. On the bright side, you discovered the problem early, before you applied your finish. I often use mineral spirits or naphtha to disclose problems like the one you describe. There are a few ways to correct the problem. In order of preference, I’d first try to strip the glue with lacquer thinner, acetone, toluene or xylene. Failing that, you’ll have to sand or scrape off the glue spots. Just be careful not to burn through the veneer. Apply the white spirit again to see whether or not these measures have eliminated the problem. Best of luck and practice patience. Glue spots, if that’s what they are, can be a real pain in the neck!

Thx for the reply. I always look fir glue spots using white spirit. The panel was clean when I wiped it down. It was only when it dried that the darkened areas remained.

Have your say...
