Well you really should let the concrete cure for at least six months before you coat it with epoxy.
The manufacturer will tell you to wait even longer.
The truth is concrete gets harder and harder the older it is and Is in a constant state of curing.
I have never had a problem with the epoxy I use and have done many brand new homes.
By the time the home owner moves in the concrete is generally at least six months old.
Maybe this job will give me a chance to ride the famous Rowher Flats area.
Oh I almost forgot... I would highly recommend the flakes!!
Epoxy floors are very slippery when wet and the flakes help add texture to the surface.
Straight epoxy is slippery even when dry.
And it helps with imperfections on the floor itself and looks a lot better in my opinion.
