Response from Rust-Oleum... (archive)

The complete automotive resource for buyers, sellers, and owners like you.

I basically sent their info line a copy of my original post. This was the response I just got back from them.

Thank you for your email. There could be any number of possibilities why this is peeling. To start, though, this product is used in heavy
industrial areas and does not have a problem with hot tire (or wet tire) pick-up. That's one reason it is used so often.

1. How much material is on the floor? If the product was spread too thin, that may make it easier to come up from hot tires.

2. Even though air temperature was in the low 70's, the concrete would have been much cooler (especially overnight). Because this is a chemically cured product, not air cured, the product may have stopped its crosslinking
process if it got too cool. So it may not have gotten a good bond as a result.

I'd be happy to send another kit to touch up those areas but temperatures aren't getting any warmer now and you definitely would have a drying
problem. The mats may have to do for now. And the rest of it should be fine as long as you have mainly just foot traffic. Keep in mind that it
may not be as chemical resistant either.

"1. How much material is on the floor? If the product was spread too thin, that may make it easier to come up from hot tires."

The garage is about 20'x24'. Each coat used roughly one package ( 1 gallon of epoxy, 1 gallon of activator).

It handled the tires fine when dry and I even had the tires on my car sliding over it (they are stickier tires then the ones that pulled it when wet) from jacking the car up/down without a problem. I just had the problem with the wet tires.

"the product may have stopped its crosslinking process if it got too cool. So it may not have gotten a good bond as a result."

Will it continue to cure slowly over time if the temp warms up or is it done forever now. I could try heating it in areas with hot air if it would help.

"I'd be happy to send another kit to touch up those areas but temperatures aren't getting any warmer now and you definitely would have a drying problem. "

I'd appreciate that. Will the product bond to the existing floor+coating OK? If it will work I could touch up the pulled areas of the floor next spring.

"The mats may have to do for now. And the rest of it should be fine as long as you have mainly just foot traffic."

I put down carpet runners for the tires on the one side to prevent it from getting worse. Is the coating possibly still curing? And if so will it strengthen over time?

Thanks for the information. I really do love the look of the floor with the coating on it but it just doesn't yet seem very strong to me.

So it not being fully cured is a possibility I guess. The istructions say it is good for vehicle traffic in 4 days though for temps of 50 degrees and up. I waited 6 before driving on it and it was on the 9th day when it pulled from being wet.
