I’m building a bulletin board for my sons’ room to replace an old piece of crap. It feels so good to throw something away when you can replace it with a new project. Its’ rolled cork glued to 1/2″ drywall, I’ll paint the edges with elmers glue to seal it good. Did one in walnut for my daughter a couple of years ago.
Anyway, It’s white oak, I have two coats of Minwax (Provincial) stain on it and was going to start the poly yesterday or today. But I noticed yesterday its all splotchy (is that a word) on one side. The other three sides look fine. The darn thing looks like someone drapped a wet towel over it. It was stored in a vertical position up off the cold floor.
Never seen that before! What do you think happened. My shops warming up right now and I’m going to try a third coat of stain late this afternoon.
Enjoy, Roy

Roy -sounds like the stain bled from the pores while drying. If you use a wet coat of penetrating oil-base stain on oak, the stain will fill the pores and then as it dries it will seep back out and cause dark spots around the pores. The more stain you use, the larger the spots. Standing the boards while drying will enlarge the spots as the stain will run a bit as it seeps back out. Oil finishes, like Watco, do the same thing.
What to do is up to you. You can use lacquer thinner and steel wool/scotchbrite to rub out the board removing the spots in the process, or you can sand them out, or you can leave them.

Did you happen to get glue on the blotchy side? Even if you wipe it off, it will retard stain penetration. sanding is the best solution. Wiping with mineral spirits will show where you have glue to clean up before staining.

Thanks Paul and Bill for the reply's. It wasn't pore bleeding, althought there was some in a few places, I let the stain soak a long time and reapplied before wiping it off. It was more blotchy, had kind of a sunburned look in places. It wasn't glue either, too much area affected to be that, more than half the surface had the problem.
I lightly sanded the entire front with 400 and did a third coat of stain. I checked it last night and most of the problem is gone, only one small area remains affected. I may repeat the sanding or just go for the shine of the poly masking it.
I'm thinking contaimination of some type. I sanded and stained the frame in a single afternoon but may have grabbed the wrong cloth. I went through the shop and trashed all suspected soiled cloths. Doh, there were several. May have not played it careful enough because it was a small job.
Enjoy, Roy
