Comparing Quotes
Ask every installer for the coating system and number of coats, the prep method, whether moisture testing is included, the flake coverage, and the written warranty terms. Then compare them side by side.
Frequently Asked Questions
What is the cheapest option?
Garage floor paint ($2–$4 per sq ft per HomeGuide) and sealers ($1–$3) cost least but don’t last as long as epoxy or polyaspartic systems.
Why are some quotes much lower?
Usually thinner coatings, acid etching instead of grinding, no moisture testing, or a shorter warranty. Ask each installer to list the system and prep.
Is labor a big part of the price?
HomeGuide says labor is often 50–70% of the total, and Angi puts it at 33–60%.
