Epoxy Floor Oil Stop Primers

[ABQ_woodworker]

Hello,

I want to epoxy my 950 square foot three car garage. However, despite my best efforts using a variety of methods there are a few oil stains that just refuse to come out. I've tried everything with marginal success (the stains are less visible). But marginal success = failure, as water still beads. I'm done fighting the oil stains. For the purposes of this discussion, consider the stains permanent.

I found multiple "oil stop primers" on the market designed specifically to bond to concrete contaminated with oil stains, and support a later coat of epoxy. HOWEVER, each of these options state that they are designed for petroleum-based oils, not synthetics. I have no idea what kind of oil stains are on my garage floor, as I bought the house used. So...dilemma.

Any recommendations? Any actual experiences in a similar situation (good or bad)?

Thanks!

Try pour n restore as a first step, diamond grind. You may not need the oil stop.

My bet is the oil stains were not synthetic. I wouldn't waste the money on a car that needs a diaper.
