Cleaning Tire Stains from Epoxy Floor

[72Anthony]

Looking for advice on cleaning tire stains from a U-Coat It epoxy floor (two coats of epoxy and clear urethane top coat). The floor was painted six years ago and the stains are from a Corvette (soft compound tires) that is a low mileage weekend car that tends to sit in place for a week or two at a time.

Thanks,
Anthony

Here's an article with some tips. Tire stains can be stubborn and depending on the quality of the top coat or epoxy, sometimes they just won't come out.

That stain is a reaction between the coating and the tire. More than likely will have to sand them out and add another clear coat.

reaction between tire and coating? to me that would raise the question, what coating is that? As I'd never want something that reacts to tires if at all possible. I can understand markings from turning, but not from just contact and sitting.

Plasticizers from soft compound performance tires or certain all season tires tend to bleed or leach out of warm tires. When you park on a coated surface, these plasticizers can migrate into the top of the coating. Lower performance coatings have less dense cross-linking when the coating cures and can allow these plasticizers into the upper surface of the coating. Higher performance coatings have a much more dense cross linking and does a much better job of resisting plasticizers.

If the tire marks can't be removed after utilizing the various tips and tricks that sometimes work, then the only way to get rid of them is as Scotty said. Sand them out and add another coat of clear.

Shea nailed it 100%. One other cause could be a coating that does not cross link all the way. This could be from site issues(moisture, cold temps, etc...) and very unlikely but possible, a bad batch of product. Good QC helps to prevent this from happening.

Another cause could be that ucoatit may blow. I had it say ten years ago and it eventually stained all over and they wouldn't come out. Formulation could be different but that was my experience.

Shea nailed it and yes you may end up sanding. This has been a major industry issue which is mitigated but not 100% resolved with a good urethane.

Agree with above, the compounds in certain tires can stain virtually anything. We have had projects that one car'side was pristine, and the other side had stains, hence proving it was the tires, and not the coating.

A high performance urethane helps greatly to prevent this, or if it does start, get parking pads to park on.
