I have been experimenting with some dyes and stains on a glued up panel of alder. It’s about 18” x 24”. Before any experiments, my panel was flat. I tried a GF water-based dye on it about a week ago and just tonight I noticed that the panel was cupped away from the side I experiment on. Could this be from the water in the dye or just the weather (it’s been rainy lately)? It has been in my non-climate controlled garage.

What should I do to fix this. It’s going to be used for a project. Will it just fix itself if it dries for longer?

BTW, this panel is 13/16” thick!

Could be one or the other, or both. Have you applied any dye to the back side? If not, give it a try and see what happens in a days time or so…

I would venture to guess that it is a combination of both, I can’t say for sure though. I have not had this happen when using water based products before, but doesn’t mean it can’t happen. I do use a lot of alder and I have never gotten it to un-cup once the damage is done.
You could try to either clamp it down to a flat surface til it dries out, but I haven’t had any success with that.
Or cut it at the glue points, re-square the pieces, then glue it back together, but of course you will loose width and thickness.
If it is badly cupped you are most likely going to have to redo it.

Yes it was your dye and you should be able to fix it with a hair dryer. I had something similar but more spectacular happen to me. see: It shows the problem and the fix.
