Here's the issue.
I used an epoxy floor system for my floor and everything worked out perfect for me with it.
I am trying to help out the supplier I bought this product from that had a customer's job that went very bad.
It's a 3 to 4 step system (over 3-4 days) on concrete that has been prepared with a diamond grinder.
The first step is a clear epoxy primer (100% solids) applied at 5 mils.
The second step (day 2) is a colored epoxy (100% solids) applied at 12 mils.
The third step (day3) is a clear 90% solids 2 part urethane top coat applied at 4 mils.
The fourth step is optional and is a second 4 mil coat of the clear urethane. (I did this on mine.)
This customer had parts of the floor delaminate between the primer and the color coat. But, it did not happen until the day after he applied the urethane in step 3 (which it also looks like he doubled up and piled on too thick).
Here's what he did way different than me:
After day 1 and his application of the clear coat, he noticed several imperfections (bubbles) caused by some gassing out from the concrete because of temperature. (In the summer, the directions say to apply this in the afternoon or evening (to eliminate that problem) and he started in the morning.)
Anyway, he decides to sand the areas to clean up the bubbles. Then, since he has walked on the floor, he says he degreased the entire floor with denatured alcohol. (I think this is where he went way wrong.) He gives it time to dry (the alcohol) and then applies his color coat (step 2) and calls it a night.
On day 3 he says everything looks good and dry and goes ahead with step 3 (however, like I said, he piles it on too thick. At this point he says everything looks OK but he didn't think the clear leveled out well.
On day 4 he wakes up and sees this:
The whole floor didn't do this but probably 30 to 40% of it did.
What do you think guys, was it the denatured alcohol? Bad mixing of the color coat? Piling on the urethane thicker than directions? Combination? Did he lie and use lacquer thinner instead of denatured alcohol?
And, btw, the manufacture tracked batch numbers of the product that this guy used and no other customers using that same batch reported any problems.
