Did it ever harden? And how long did it take?
Funny you should ask. No, it has not hardened completely yet... I emailed Epoxy-coat yesterday but haven't heard back yet. It's hard enough to walk on and I'm storing stuff out there with no problems (shelves are up, etc). However, I had a little mishap when trying to park a car on it for the first time...
Here's the details of what happened:
I rolled my floor down November 20th (base coat) and 21st (clear coat). It was hard the next day, but not "rock" hard or fully cured by any means. I waited a week and I noticed that I could still leave a blemish with my fingernail. I called and spoke to someone at Epoxy-coat on the phone last week, and the person I spoke with said I should wait another week and then it should be cured. I did the fingernail check a few times and it seems to be getting harder to leave an indent in the coating. At one point on Friday I wasn't able to leave an indent.
Monday came around and I decided to park on the floor for the first time. My tires were cool and dry when I pulled it in (car was parked outside all day) When I pulled out of the garage later that night, I noticed that there were very noticeable tire marks in the clear coat (see attached image).
I'm certain that my mixtures were right. I meticulously prepared the floor, and am even more certain in my mixes for the clear coat than the base coat as I had already done it once the day before. Temperatures here have varied since but on application days it was mid 70s during the day and high 50s at night. Since then it has dropped lower than 50 for only a few days (last weekend, one week after application), but most days have been in the 60s or low 70s with nights dipping down into the 40s and 50s. The floor temperature has seemed to stay relatively close to 60 degrees in temperature since application.
When I got home from work yesterday, I was chatting with a neighbor who asked how the floor turned out (he is thinking about purchasing an epoxy-coat kit as well). I told him it looks great but that it hasn't cured yet and went to show him the marks from the the tires where my Jeep was parked on it. To my surprise, the same mark in the attached picture is 95% gone. I could not believe that it "healed" itself so well. Both marks seemed to have "healed" up enough that no repair will be necessary provided the floor eventually gets hard. You would have to really look or know that I parked the car there to see the marks. I even have a had a hard time finding them today.
The million-dollar question now is, what's going on and when is this floor going to finally cure?
