How it goes down
The prep is the product.
Garage floors, basements, patios, driveways, walkways and pool decks, coated with a polyurea base and a polyaspartic clear top coat — not epoxy. Polyurea is 4× stronger than epoxy, stays flexible through temperature swings, shrugs off oil, gasoline and road salt, and does not yellow in sunlight.
Crews grind the slab, vacuum it, treat cracks and pitting, then roll the base coat and broadcast color flake by hand while it is wet. Once it cures, loose flake is scraped off and the clear coat goes down. The floor is dry to the touch in 12 hours — walk on it the same day, park on it after 24.

“5 stars isn’t enough to describe the service and results that I received from Shon, Tracy and Cory! I love my garage floor. I was given so many fun choices in finishes but Aurora Accent is bright and sparkly! Thank you for giving my garage a cool vibe!”
“Ethan and Shay were great with our Garage floor installation, they came out in freezing temps after it had just snowed and weren’t sure if the floor would cure in that weather but made it work and put in extra time to finish the job in one day. We are so happy with how it turned out!”
Answers
Concrete coating questions
Polyurea versus epoxy, cost, cure times and what we coat.
Is polyurea better than epoxy for a garage floor?
For a garage, yes. Polyurea and polyaspartic coatings stay flexible, resist hot-tire pickup, and do not yellow in sunlight, all of which epoxy struggles with. Polyurea also cures in hours rather than days. Epoxy remains cheaper up front, which is why it is what most big-box kits contain.
What is the difference between polyurea, polyaspartic, and epoxy?
Epoxy is a rigid, slow-curing coating that can yellow and lift under hot tires. Polyaspartic is a fast-curing, UV-stable subset of polyurea often used as the clear top coat. Polyurea is the flexible base layer. The systems we install pair a polyurea base with a polyaspartic top, which is why they can be walked on the same day.
How much does garage floor coating cost?
It comes down to square footage, the condition of the slab, and how much grinding, crack repair, and moisture testing it needs before anything is applied. A slab in good shape costs meaningfully less than one that needs repair, so the inspection comes first and the estimate is itemized and free.
How long does a garage floor coating last?
A properly prepared polyurea-polyaspartic floor lasts 15–20 years or more. Almost every early failure traces to preparation rather than product — a coating over a slab that was not ground and moisture-tested will peel regardless of what it cost.
How long before I can park on a new coated floor?
Foot traffic the same day, vehicles in about 24 hours. That is the practical advantage of polyurea over epoxy, which typically needs several days before a car can go back in.
Is coating a garage floor worth it?
It is if the slab is staying. A coating seals concrete against oil, salt, and freeze-thaw spalling, makes the space far easier to clean, and brightens the garage considerably. On a slab that is already cracking badly, repair has to come first — we will tell you if that is the case.
What surfaces can Three Stone coat?
Garage floors, basements, patios, pool decks, walkways, and commercial and warehouse floors. Vertical surfaces and stair treads can be coated to match.
