Subject : Removing veneer tape glue
Posted : 2007-10-09 9:44 AM

I've veneered several panels with birds eye maple with joints in the veneer taped with veneer tape. After the veneering I remove the tape by moistening with water, gently scraping it off, and a final sanding. Problem is some of the tape glue penetrates the veneer and leaves a slight discoloration. What can I do about this?

I think you need to wash more vigorously. I use water with a gray abrasive pad then wipe well with a rag. I haven't found that getting the veneer really wet hurts anything. If you've any loose spots, they will surely show up with this treatment.

Agreed.

I usually literally flood a panel with water.

This will aid in getting all the tape residue off, and if your glue up wasn't good, you'll know it when you get it good and wet.

Have you tried using clear packing tape? Try it. You will never look back.

I used to have this problem too. The stains from the veneer tape became even more obvious when I was using aniline dyes, which I use a fair bit. And it would not matter how much you scrubbed the seam, or how much water you used. And after searching the internet, I found others who had been having the same problem. So I started using a veneer stitcher. It's a significant investment, but it will pay for itself in the long haul because it is much faster than taping.

With veneer thread though, you will still have to scrub the seam to remove the hot-melt glue residue after knocking the thread off with a card scraper. I've found lacquer thinner does the trick. And again, this process of removing the thread is much faster and easier than removing veneer tape. Or packing tape either.

I wouldn't want to use packing tape on seams as it sometimes lifts pieces of the veneer when I remove it. I only use it to hold the veneer and substrate together, and only over 2" paper veneer tape.

I've never sanded through in removing veneer tape glue residue, if that's any consolation. I generally sand with 80 grit to remove most of the paper, then 150 to remove the 80 scratches, then 220. After flooding (water) with a wet sponge and letting dry, I'll sand with 220 any remaining glue residue and then wipe with a damp sponge. I'll sand and wipe again as needed until all the residue seems to be gone. However, I seldom stain the veneer. Most often I'll wipe on a thin coat of boiled linseed oil, dry 24 hours, seal with shellac, then water borne finish.

Along with all the other excellent ideas on this thread I would like to add one more, which is to glue the seams together. I don't do it all the time but in certain situation its a great option.

You simply pull the joint together with strips of masking tape and then run one long piece down the entire seam. Fold the joint back on itself like a book and run a fine bead of glue down the edge of the veneer. Fold the veneer back flat and remove the squeeze out with a chisel. Lastly, run another length of masking tape down the seam on this side. Let it sit for a least 15 minutes and then take all the masking tape off. On relatively flat veneer it works perfectly but on wavy veneer you run the risk of gluing the seams together not perfectly aligned. To avoid this problem, if necessary, just put the veneer in your press after taping and the seams will be forced flat to each other.

With this technique there is no after pressing clean up at all.

Sincerely
Darryl Keil
