I don't post here very often, but one of the best research tools for a flooring question is
The Garage Journal They have an entire sub-forum dedicated to flooring and the various products.
I used Wolverine epoxy and it has been down for about 4 years now. There are no slippage , lifting, peeling, or staining issues at all. The wolverine epoxy is 100% epoxy, with a low VOC. What is applied to the floor stays on the floor, with very little evaporation or gas-off.
As others have said, prep is everything, and the front half of my project was (is) 35 years old,
oil soaked to the hilt, and the back half was new concrete. I rented a clarke floor buffer and then used a combo of simple green, and then chased it with muratic acid. It took over a week to dry out before I could do the coating.
One of the major drawbacks with any epoxy is that you cannot weld on it. The sparks and slag will burn it in a heartbeat. Other than that, I do not use my creeper any more, it is very easy to just slide on the floor. And since the floor is sealed, there is very little dust from the floor that gets onto the cars. The entire garage is a lot easier to keep clean. It is also impervious to any chemical, and the weight of the tool box or engine hoist dosen't phase it. I rent the clarke once a year to buff the floor, and also keep a wet mop handy to take care of any spills.
Cost was approx 1.50 per foot.
like I said in the beginning, go to
The Garage Journal and read their flooring pages.
