Yes, you can.
Yes. With either an oil based paint over a high adhesion primer, like XIM, a single part epoxy or a multi-part epoxy.
I wouldn't. I would try to get the first one to cure somehow, possibly by warming that area.
You can definitely use latex paint over epoxy. In fact, it is recommended to use latex over epoxy by the paint manufacturers, rather than using epoxy over epoxy. The latex adheres better and if you then want to use epoxy next time you paint, you have a nice coat of latex between the layers. If you use epoxy over epoxy, often the paint will just peel off in layers once some time passes (and sometimes right away).
Yes you can.
Yes, but it may not stay on very well. Besides, epoxy paints are very hard and wear resistant, while latex paints aren't. If the epoxy paint was needed the first time, repainting with something much less durable might not be such a wise move.
You should remove the oil based paint before applying the epoxy. Many epoxies will actually act as a remover when put over oil-based paints.
Best to remove the epoxy first, otherwise you could experience some peeling issues. If you insist on not removing the epoxy, be sure to remove any grease or oil, clean and sand the surface flat so the floor paint has a solid surface to gain a tenacious bond.
Yes, you can.
I wouldn't if it was my driveway. I'd power wash it off first then the driveway coatings would stick better.
I,v got over 20 years inpainting. application, you know...learned it the hard way. painting over epoxy is always tricky.( I,m talking about the two part epoxy) if you start with epoxy and stick with epoxy, usually you'lldo just fine. any kind of latex paintwill lift off of epoxy. oil paint will stick a bit longer, but that's coming up to.thewhole point of epoxy is to have nothingstickto its surfaceso thatit cleans easy.you can try and strip it, messy and time consuming. now your mixing chemicals. one tip.. take a piece of sand paper, sand a small area. if what you sanded leaves dust.. I would paint that. if balls up or rolls? its the same as painting over rubber. hopes this helps.
Not directly. You will need to use a primer made to adhere to oil and will accept a latex topcoat.
Latex paint will go over WD40 but will not adhere. I work at paint stores and we spray our mixing tables with WD40 so that the paint cans will slide easily and any spilled or splashed paint will peel off if dried.
