I will tell you that the acid washed floors I have seen have had peeling problems with them because the epoxy cannot chemicaly bond with the concrete. The diamond ground floors however get rid of the whole surface and it's contaminants thereby allowing for a great surface to bond to.

Mine has been done for just over a year and I love it, but I diamond ground it before I epoxied it.
Just my 2 cents.
