I built a table in Maple, then applied Pre-Stain Conditioner and then applied Minwax stain. I got these areas where the stain is much lighter and it looks really bad. It wasn’t visible in the wood before I stained. What did I do wrong? Is there anything I can do now? See photo. thanks!

DTrak,
How long did you wait after applying the conditioner before applying the stain? I don’t have any experience staining maple in particular, but I know my first few jobs turned out splotchy because I waited too long after applying the condiitoner. Per a demonstration I saw from a professional finisher on an episode of Ask This Old House, he was adamant about waiting no longer than 90 minutes post application, ideally targeting only half an hour.

I waited about 10mins before applying stain which is what instructions said (“5-15 mins”).

Im assuming you used MW solvent conditioner. It looks more like glue residue vs a conditioner or stain issue. If those light areas had conditioner applied somehow just before stain, that might be it. Here is some info on blotch control.

That’s glue contamination. Most of the spots are near joints. It will have to be sanded back to bare wood and refinished.

Next time wait until the glue is rubbery and scrape it off with a chisel. Avoid wiping the glue with a wet rag (as I was taught to do as a teenager), because it actually causes this problem.

Good luck with it.

I used, “Minwax 13407 Pre-Stain Wood Conditioner, 1/2 Pint” .

I’m still trying to understand the glue contamination. You are right, I made the mistake of wiping with a wet rag, but I sanded thoroughly after. Did the glue seep into the wood somehow, and if so, waiting until it is rubbery would give it more time to seep in and the chisel would just scrape the surface, no?

Also, some spots are not close to the joints. I circled them in red.

I can sand all that down and stain again, but I am afraid I will get the same result.

How long did the glue dry before you sanded it? If it was still damp the sanding didnt accomplish anything. Whatever the case, the piece will have to be stripped/sandedto get even penetration and coloring. This may sound ass backwards to you, but after stripping it down, i recommend glue sizing, thinned wb finish, or one of the commercially available conditioners I discuss in my blog vs the MW solvent stuff. It will take quite a bit of sanding to strip the glue and stain.

I’ve been wiping glue with a wet rag my whole career and never have that problem. Maybe it’s a matter of using a clean rag and keeping it rinsed and making sure you wipe the area well.
To each there own, but like I said, never has been a problem for me.
