New epoxy coating/parking on it?

[Darren1320]

Having some problems with an epoxy coating I had a contractor put down. The slab is about 8 months old. When it was fresh I sealed it. Couple weeks ago had a contractor come in and put down a Corotech waterbase epoxy. He sanded the floor, acid washed it, let it dry for a couple days then rolled the product on. Waited a week then I pulled the race car into the shop a parked it. About a week later I came out moved the car and areas of the epoxy stuck to the tires and peeled off of the concrete. The car does have slicks on the back but has regular BFG TA radials on the front. Tires could be a little more sticky than a regular tire has they could have some of the sticky compound on them from the race track surface.

My question is though should this not happen. I spent the extra money going with epoxy thinking this would not happen. How can it be fixed? Contractor mentions touching up the spots where it peeled off. I would think it would all have to be redone?

A pro "residential garage" epoxy-system should look like this:
Grind the floor
Make repairs, if any
Epoxy Penetrating Primer
Epoxy Base Coat (100% solids)- flake if desired
Optional: urethane topcoat with non-skid.

If you have special tires then a non-skid may help but we have contractors pulling dump trucks, 18 wheelers and fire-trucks on our materials without issue. It's all in the prep/primer.

Repairs will be noticeable. IF you want it done proper, grind the floor and start from scratch. Dont settle for sanding the floor, and re-coating.

You're tires are not crazy sticky, it was poor prep.

noted the OP said "Corotech waterbase epoxy"

maybe the epoxy is not as good as the other ones ppl use

and of course if prep is correct then you will have problems

If the prep was done correct, the floor should not have peeled.
Your contractor should have prepped the floor by using a diamond grinder or shot-blasting. I have never heard of a contractor using the acid etching method. That method of prep is more for a DIY application.
When there is a sealer on the floor, it has to come off of the floor to allow the coating to bite onto the concrete. A sealer on the floor will not allow a prime coat or floor coating to bond with the concrete.
I would contact the contractor, honestly. I'd hate to tell you that the whole thing needs to be redone, with a diamond grinder this time. But that is honestly the only way to achieve the best results with no flaking/peeling/hot tire pick-up in the future.
Best of luck to you. Hopefully the contractor will work something out with you.

Oops, forgot to mention. Even when you are DIY applying, and there is a sealer, you will still need to diamond grind.
