7. You should be able to remove those glue globs.

How much of that is there ? Is it glue from a glue down carpet or some other flooring ?

Upstairs I had painted flooring a protective coat of some kind of crappy paint. just ruined the wood flooring.
I used a disk sander ,with a course sand paper to strip that stuff. what a job. Used paint stain remover to clean up the residue,what a mess.

I used a dark stain for a finish than decided I hate it.

So I found some really cool,good quality flooring -floating floor and did one bedroom. It looked so good I did the entire 2nd, floor.
Than I put the refinishing effort into the stair case and railing. That I liked the finish results. Next came the wainscoting on the walls.

So now we have the look of new that blends right in with the old look, our floors stay warm in the winter and it all works.

So no I don't think you will cure the glue issue by staining over it. Glue remover stripping compound or sand it and refinish it.
Or carpet it or floor over it with a floating floor.

If you can post a picture, I'll look it over -see if something comes to mind.
