Topic tags/keywords: inlay finishing finishes ca glue turquoise walnut claro walnut fogging lacquer

I have recently tried my first inlay in a bowl. It is a Claro Wolnut bowl with turquoise filling the natural voids. I have applied two coats of Watco Butcher Block oil and just sprayed my first coat of lacquer. My question is, has anyone had any problems with lacquer fogging up on the CA glued areas? I am hoping that it is just the humidity causing it, but it is really just fogging up on my inlaid areas. Any suggestions on what I should do? Should I sand it all off and go to a poly finish? Any and all input is always appreciated.

I’m not an expert on lacquer, but my first thought is that this has something to do with the oil. That butcher block oil will soak into the wood, but it’s going to sit right on top of the glued inlay areas. I would think the CA areas would have to be wiped clean with a solvent before spraying.

All that is purely a guess. I’m interested to see what the experts weigh in with.

It most likely isn’t a good idea to apply lacquer over any oil based finish. I have had varnish and laquer turn milk white over repaired ca glue repairs, but in almost all cases a second coat removed the white. Make sure you scuff sand the laquer first before you apply your second. If it doens’t, scuff sand the laquer and take an “Oil based” colored pencil and color the area the color it should be, I use Prisma pencils and they do a wonderful job of hiding knots and odd repairs like yours. Hope that helps.

Here’s a little update. I sanded the bowl back down and wiped the glued areas with denatured alcohol. Prolly didn’t need to after sanding but I did anyway. I re-sprayed it and put it in our climate controlled basement/recording studio. It appears to be fine now. Now the problem is I don’t know what lesson I learned, haha. Was it the oil residue on top of the glue or did the glue and lacquer react differently in a humid environment. I’ll definately wipe the glue down with a solvent before my first coat of finish from now on and I guess I’ll have a smelly studio from time to time also. Thanks for the input fellas. I hope some more LJs will shed some more light on this subject.

I think Charlies guess was right on target. For that matter, so was Hacksaw’s. Laccquer over oil base is not a good idea. Oil-based stain however will work under lacquer, but it must dry completly first. I have seen it turn milky if you rush putting on the lacquer.

It is very likely that you had blushing from the humidity also—a common problem with lacquer.

Personally, I doubt it was the CA glue. I have spayed lacquer over Ca without issues, but it was very small cracks that were filled with it. I am not sure about larger amounts.
