Garage Floor Coatings: What Makes One Last for Years and Another Peel in One

The three things that decide it

1. 1The bondDiamond grinding removes the weak top layer of concrete and opens its pores, to a profile of about CSP 2–3, so the base coat soaks in. Etching or just washing leaves a surface a coating can only sit on.
2. 2The buildA full base coat, a full flake broadcast and a real topcoat add up to a thick, tough layer; polyaspartic coats go on at about 6–12 mils dry each. A single thin roll-on coat is what hot tires peel up.
3. 3The slabMoisture coming up through the concrete, oil, old sealers and settled sections all need handling before coating.
