Clear Coat for Oily Floor

[dorkjackson]

Guys, I'm hoping you can give me a recommendation for a winery floor. The building was a machine shop and has some oil? spots that have probably been there for 20+ years. They are still there after grinding 2mm off the concrete floor. I've tried a number of things, Behr concrete degreaser, stuff you pour on and let dry and vacuum up, Oxyclean, Dawn Dishwashing detergent, and as of this morning, Muriatic acid. The stains will go away for awhile, but a few hours later, there they are again! Soooo… The floor looks great with the exposed aggregate from the grinding. I want to clear coat it. Is there some sort of coating I can use over those migrating oil spots that will give me the following: not super slippery when wet, easy to clean, stainproof, can stand some light standing water, enhances color, durable and acid resistant. I would prefer a light gloss finish, but don't really care if it can do the rest!! Help! Thanks, Kathy

We have the right stuff.
However, I am leery about the reoccurring oil stains.

Oil will break a bond.

 

[dorkjackson]

Me too. Is there anything else I can try to remove them? I feel like I'm fighting a losing battle with them.

Which of your products would you recommend? I was looking at your HD-015 epoxy.

Good choice.
(2) thin coats is required.
Perfect for sealing raw or stained concrete.

My one concern is the epoxy is waterbased and I know oil and water don't mix!

My StonHard Epoxy rep once told me that if you were to coat the surface after cleaning but before the stain re-appeared, you would have success. The theory was that since you
removed the stain from the surface and the coating you are applying will bond to the clean surface. The reappearance of the stain is simply the residual staining material in the concrete being reabsorbed into the cleaned area. The stain is supposedly trapped under the topcoat. I believed him, and did my floor with StonHard and it was a pretty FILTHY floor. It's been there 11 years now, no failures, thankfully.

It may or may not work but is there something you could put on top of the concrete, like more concrete? Maybe put an inch of concrete across the entire floor and that would fix the oily floor problem and help to cover any cracks or low areas. Then apply your sealer on top of that.

We have an oil primer for floors that are oil contaminated and can't be completely cleaned. Like your floor.

Caveat: this product is BLACK. It will take at least (2) coats of pigmented epoxy (darker color) to cover it.
