I applied oil-based stain to my foyer floor a while back, and now I'm in a bit of a bind. I originally planned to use oil-based polyurethane for the finish, but it turns out I won't be able to let it cure properly due to foot traffic coming in just four days. I read that I might have better luck with water-based polyurethane, but I've also heard that using shellac as a barrier is a good idea when switching from oil to water-based products. The stain has been drying for over two weeks, so I'm wondering if it's safe to go ahead with the water-based polyurethane now without risking any issues like blotching or adhesion problems. I'd like to get several coats on within the next couple of days before the floor needs to be used again. Any advice would be greatly appreciated!

If your stain has fully cured, you could be fine using water-based poly. Most brands will say it's okay to apply over dried oil stains, but check the specific instructions for the product you're using. Some manufacturers even warn against shellac layers, so it's worth looking into. Also, testing a small, hidden area before you commit is always a smart move.
Honestly, mixing water over oil is generally advised against, so I'd be cautious. Check your oil stain can for how long it needs to fully cure because some of them can take longer than two weeks. Also, sealing with shellac might trap in any partially cured oil, which could really slow down the drying process. If the floor is as it is and has dried for a bit, maybe consider putting a rug over it until you can finish the job properly after the visit?
Make sure to follow the product directions closely. Your timeline is tight, so consider that. When it comes to shellac, it dries super fast—like within 15 minutes—so you won't have to wait long if you decide to use that. But for a first shellac project, maybe avoid using it on a floor? Also, posting this in specialized flooring forums might get you quicker responses from seasoned pros!
That makes sense! I really don’t want to risk messing up the finish, but I’m stuck with the timeline I’ve got. I'll have to put a rug on it for sure.
