Armor Clad and Epoxy-Coat are both 100% solids epoxy with an average dry film thickness of 10 mils with better abrasion and wear resistance.
The RockSolid polycuramine garage floor coating is about 3 mils thick. In our opinion it's a better DIY kit than the typical home improvement low solids epoxy paint kits such as EpoxyShield, but it can't compare to a quality 100% solids coating.
