I am having my garage floor done with an epoxy system. The contractor is using Corotech (Benjamin Moore) V155, V430, full broadcast flakes and V540 topcoat. I asked about V500 but he is saying that the catalyst is unavailable. Will 2 coats of the V540 be adequate for a residential garage? I know it is a waterborne product so somewhat inferior to the standard solvent based urethanes.
