Weird stain problem


I'm staining a couple of new oak stair treads. I sanded down to 320, and filled the grain with Behlen water-based filler. I waited over night, then sanded it back to 320 (Behlen says to wait overnight before using solvent-based finishes). I applied Minwax Provincial stain, waited a few, and wiped it off. So far so good - looks nice, good grain pattern, even-ish color (the treads are edge-laminated, and the wood color varies some).
After a couple of hours I went back downstairs to do something else, and to my horror, there are beads of drying stain all over the surface. It looks like the stain is welling up from in the wood in spots. I used a clean rag to wipe the surface, smoothing it out and blending the color again, but even before I finished doing the second tread the first one was beading again.
What the heck did I do? The workshop is at a normal temp & humidity - about 75 degrees, inside-of-the-house conditions.
Thanks, PK

Hi Pk, That is not that unusual in oak for certain stains if the pores are not completely filled. Some people watch the item for an hour or so wiping the stain off as the stain leaves the pores. If you search the site below using " oak bleeding" you will find some discussion of the problem or you can register and ask your question directly. Generally get very good answers. Cheers, JG

It finally stopped after 18 hours of wiping periodically. Now I just have to wait for it to completely dry before the poly.
Thanks!
