The gap between a DIY kit and a professional install
That 150 garage-floor kit in the big-box store is typically a water-based fortified latex paint, not epoxy. Professional systems are 100% solids with a film measured in mils of DFT — and the difference shows up in adhesion, durability, and how the floor handles moisture vapor from the slab. This deck walks the full comparison. Most homeowners who read this are comparing diy epoxy floor vs professional options around Fairfax, VA, so what follows sticks to the details that change in practice.
