I didn’t realize the Fast Drying Poly I bought was oil based until a few minutes ago. I just painted a table with a Black Eggshell water based paint and I don’t want to ruin it by using the wrong Polyurethane. I don’t think the Eggshell will stand up to abuse without a sealer.

yes
You can use oil over water with polyurethane, but not the other way around. Using water based poly over oil stain causes it to pop off. Hope this helps.
You can use the fast drying over the latex paint. Don’t work the poly too much though. Try putting it on evenly and not work it too much.Just make sure it’s completely dry before adding another coat.
I painted a concrete floor to look like wood and used latex paint. I sealed it with poly.
