Wiped off the stain and ended up with these areas where the stain didn’t soak in. Was just sanded today and there was no oil on the wood at all. The top is plywood.

Thanks…...John

Might be the glue used that migrated through the layers as the plywood was manufactured. If it is you’ll have to use an alternate methor to finish. I will let others discuss those.

Looks like you may have sanded too much and removed the bulk of the finish veneer and are left with veneer that has absorbed glue and isn’t porous enough to take the stain. You cannot sand finish veneer very much or else you’ll go through to the next layer.

Thanks for the feedback guys. I sanded very lightly as the old finish came off very easily. I guess the prior owner, or the maker of the chest got pretty aggressive.

Big time plus 1 for Tom. Having refinished pro for 12 years, I went through a couple of veneered surfaces in the beginning before I really realized I have maybe, maybe 10 thousandths of an inch of veneer to work with.

At this point, you have basically two options:
1. You can tint the plywood or possibly paint it by blending it in with your fingers and a soft brush, let it dry and try to continue.
2. You can discover where the veneer stops, and the plywood begins, and cut back, and reinsert veneer and glue it down. This time around, make sure you don’t sand through the veneer, and good luck color matching.

We actually used to keep cheap old furniture parts lying around the shop for this very purpose – when a piece came in with a piece of veneer missing we would scrap a chunk off an old furniture part because it looked more similar than new veneer. Or, either me or my partner got just a little too aggressive with the sanders, which after the first year or so never happened again.

Either way, it is a pain.

NOW, if you are SURE the whole top is plywood, ignore the above. In this case, the glue or bonder used in manufacture has seeped through. You can try to sand off the glue down to the next available wood, but beware, there may not be more wood as the bonder would have seeped right through to the second layer. But to my eye, that is not the case. What you’ve done is sand through the thin veneer on top.

Another alternative would be try some dyes and/or gel stain to bring up the match the areas, then use a shading technique with your finish. Multipal applications may be necessary and drying between applications…...As above “it is a pain.”

Maybe a varnish stain can rescue the project. I’d try to get all the finish & stain off to a more or less uniform appearance. Then apply the varnish stain. This sits on top rather than sinking in. It might just do it.

+1 to Tom. however, the whole project would have to have all the finish & stain off on the top as well as the table base to have the project match. Still a pain.

It is probably much more than you bargained for, but you could veneer the entire top and have a fresh surface to work with.

Thanks again for all the feedback guys. I am going to re-sand and veneer over the top. This all started out as a freebie gun chest that I was going to turn into a toy chest for my grandson. I ended up going through all the joints, fixing hinges, and replacing the feet. I could have built one from scratch in 1/2 the time.

But you all know how woodworking and refinishing goes some times…...eh? :)

Doesn’t matter…......... any time is good time out in the shop.

Thanks again…........... John
