I just finished my bathroom but when i used the oil based kilz there was a little spray back that landed on the tile floor.
Depending on the type of tile you might be able to use a sharp knife (exacto or paring knife) and gently remove the spots. If you have any kind of ceramic tile that would work (in my experience) except perhaps on the grouted areas. If you have grout and the Kilz is in/on the grout you might have to actually scrape some of the grout off and then reseal the grout. Good luck. It's laborious work but it should work. If you have linoleum tile I wouldn't do that because it might remove the finish. The next time you go to the paint dept. at the store ask them how to do it if you haven't solved the problem
