Well I certainly don't work for EpoxyCoatr else I would never reccomend the stick measuring method. I should clarify that Christine definitely told me that the EpoxyCoat alone could withstand a fairly high moisture level without blistering so they don't reccomend a primer unless absolutely necessary. But if I wanted to use a primer, "Other EpoxyCoat customers have had good luck using DryLok." Also DryLok comes in water based and traditional "bad chemical" varieties.
That said I was skeptical of the bond with a primer so I didn't do it. The problem with the fish eyes for me was they didn't show up until several hours after I put it down....when I was sleeping....so I missed my opportunity to fix before they hardened.
Family:
You did a great job and your floor looks very nice.
Must interject here as you are giving out bad information to people who may use it....
Primer is primarily used to seal the floor so that the coating does not get sucked into the floor and look uneven.
Extra benefits are: reduced chance of bubbles, better penetration into the slab (100% solids don't penetrate as well as a good thin primer), blockade between things that cause fish-eyes and your base coat, etc..
and I repeat, you won't find one pro installer on this site that applies this material without a primer in a garage application or possibly any.
Lastly, dry-lock is not an acceptable primer for any epoxy system. You must use a two part epoxy that is compatible.
