Subject : Rermoving veneer tape
Posted : 2008-08-12 12:46 AM

I'm veneering lots of maple veneer panels where I tape up the veneer sheets with veneer tape. When they come out of the press I sand off the tape, really quite a bit of sanding, until no tape is visible. Then I stain the panels. At that point the glue that was on the tape is faintly visible. I've tried soaking with water rather than sanding to remove the tape. But a vigorous soaking loosens the glue. Any ideas how to deal with this problem.

I was also having the same problem, as I use a lot of figured maple in my work with aniline dyes. Darryl recommends scrubbing the seam with, I believe, some mildly soapy water and a brush. Needs to be quite vigorous. But I found that this didn't eliminate the problem that you are also having. Worked fine if I wasn't dying but the dye really makes the veneer tape shadow stand out. Eventually switched to using the veneer thread. While the threader has its own problems, it certainly solved this one and as an added bonus it makes it much faster to do a layup.

That's the firet I've heard of veneer thread. What is it? How do you use it? Where do you get it?
Thanks,
Rob

I usually soak the project in water...and don't be afraid to really drown it.

Any problems with the adhesive will show during this stage.

After it's been soaked, I use a cabinet scraper. It's much more precise than sanding.

I think that when Enrico says a veneer thread, he is referring to what I call a veneer stitcher. I could be wrong, however.

I've never used one of these, but look ingenious...but pricey.

"soak the project"? "drown it"? I would really hesitate to introduce that kind of moisture into my own panel work. It just seems like you would be asking for trouble. But, to each his own. No doubt, you've had good results or else you wouldn't continue to do this. We use a combination of a finely sharpened and tuned scraper (removes excess tape rapidly) and a random orbital sander (120 to start to 180-220 to finish). I very rarely, if at all, have any shadowing from the tape. Yes, one has to be careful with the random orbital sander but common sense and a light touch seem to work fine here. I'm not sure this is related but I also know "Distilled" water is recommended for applying veneer tape ( although I don't use this). I've read that sometimes minerals in the water can play havoc on certain veneers. Is that related to the problems mentioned? Maybe, maybe not.

When I say drown, I don't mean submerge. And I avoid the substrate edges if they are exposed.

I will get my projects very wet, and let it soak in for a while before scraping.

If you've done a good job with your adhesive, your project will always hold up to this. And if you haven't, then you'll find out then, rather then a year down the road.

Try it next time. You might be surprised. The veneer tape comes off much easier.

Veneer tape shadow gets us all. I generously wet the veneer and lift off the tape with thin putty knife. After the veneer dries, I'll ROS sand with 150 and 220. Then I'll wet the surface again and let dry. This seems to highlight any veneer tape residue, and I'll touch those areas with scraper or 220 again. I keep repeating until no more residue is highlighted (usually no more than one or two iterations). I've seldom been asked to stain the veneer, but often I will wipe a thin coat of linseed oil on the sanded veneer, and haven't had veneer tape residue show after oiling. Maybe I've just been lucky.

It's only when using dyes that I've had a persistent problem, and it didn't matter how much I scrubbed or sanded ... it was like the glue from the tape reacted with the urea resin bleeding through, which the dye highlighted. Without dye I wasn't having much of a problem.
In any case, an investment in the veneer stitcher was a good thing, as it is significantly faster to lay up and to take off.

Interesting advice, and thanks. Most I have tried withoit luck. I'm especially afraid of the water flood approaches because in my experience they can loosen the veneer glue.

I'm thinking of coating my veneers with sanding sealer before taping them up. Anybody tried this?

And yes, this problem is most evident when staining.

Give the sanding sealer a try, but I suspect you'll find applying sanding sealer to only one side will create curling, buckling, et cetera. Wouldn't risk adhesion issues by applying sanding sealer to the glue side.
