Last week I delivered a 8ft long bar to a night club in Sarasota, they called me this week to say that on the inside of the piece, the “veneer” is coming away/separating from the wood. Now, I haven’t seen the problem for myself yet so I don’t have any better description than that. I’m going back Monday to take a look at it, but I’ve never come across this problem before and I’m not sure I know how to fix it. Anybody have any thoughts?
Here are the specs:
A2 3/4 Cherry Ply
1 coat of sprayed dye (thinned with lacquer thinner 50%) *
1 coat of wiped stain
3 coats of sprayed post conversion lacquer (Scuff sanded between coats)
The finish products are used were all M.L. Campbell – production cabinet quality finishes, but it was the first time I used them. (www.mlcampbell.com)
*I’m thinking this might be the problem? Could the thinner have soaked through and disolved the substrate glue?
Any thoughts much appreciated.

Black & Decker BDERO600 5-in. Random Orbit Sander
- Fair stock removal and dust collection without a vacuum - Fair stock removal and poor dust collection with a vacuum - Sander has a regular pulse in use - Paddle switch was awkward, but the on/off lock was handy - Comfortable, but cramped waist made holding there often uncomfortable - Slow to stop
Triton TPT125 Planer
Accessing the knives on the Triton for changes was not difficult, but getting the knives out was tricky, because no magnetized handles were provided to lift the knives off the cutterhead. There is a 2-1/2-in.-dia. dust port, and chip collection was good when hooked up to a shop vacuum. The housing has an open top and just one return roller on top, making it impossible to stack boards there in between passes through the machine. Also, there is no gauge that indicates how much material you are removing in a pass, making it one of four planers that don’t offer this feature.
Double Sided Tape
A thin woven core makes XFasten tape strong yet not too thick (0.008 in.), and helps it hold powerfully without being difficult to peel off.
Shop Fox W1826
The thick, felted bag on this Shop Fox is a plus and a minus. On one hand, it makes the unit much less expensive than collectors with canister filters, and also lighter and easier to hang on the wall. Without a separate plastic bag to catch chips, however, they stay in the felt bag, and the shortish zipper on the bottom makes it tough to shake them out. Otherwise, the W1826 is an excellent value.
Makita SP6000J1 Track Saw
With enough power to slice through thick hardwoods, the Makita makes smooth, chip-free cuts in all materials.

I would say that there's an excellent chance that the veneer is delaminating - or there is a void under the veneer.
A couple of months ago, I made a paint-grade mantle for a customer using 1/2" birch ply. I primed it and left it to dry overnight and the next morning I had some "bubbles". As it turned out, the ply had a fairly large void under the veneer which wrinkled due to the moisture in the primer. I cut away the veneer and filled the void with epoxy then sanded and re-primed. Unfortunately, the repair was still visible in the right light and I wound up having to replace the bad piece of plywood.........a major PITA!!!
Good Luck
