Across the Valley, professionally installed flake floors run about $6 to $9 a square foot, and full polyaspartic or polyurea systems $5 to $11. Metallic floors run $8 to $15. A DIY kit is $100 to $300 in materials and a weekend, and in an Arizona garage it usually lasts a year or two.
By garage size
Most price pages call a 400 sq ft garage a “2-car.” Most new 2-car garages in the East Valley are closer to 576. Drag through the sizes:
Big 2-car · up to 600 sq ft
$3,490full-flake floor, all in
As low as $162/mo with Wisetack (sample terms) · $5.82 a sq ft
Up to 600 sq ft. Most new builds, and the one we do most.

Plain epoxy is cheapest up front, but it yellows near the door and can lift under summer tires. A polyaspartic clear coat is the line between a floor that lasts and one you redo.
What raises the price
- Stem walls over 8 in. or a full wall wrap: $6 a linear ft
- Crack repair past the first 20 ft: $8 a linear ft
- Pit and spall patches: $35 each
- Garage steps, coated to match: $95 a step
- Moisture-blocking primer, only if your slab tests high: $1.50 a sq ft
- Grinding off an old coating: $1.25 a sq ft
- A custom blend (two house blends mixed): $150 flat
A good quote lists these before install day. A surprise on the invoice is the most common complaint about floor companies.
What cheap bids leave out
- The grind. Acid etching is faster and cheaper, and it’s the top reason floors peel.
- A full broadcast. A “light” or “medium” broadcast uses half the flake and shows the base coat.
- The clear coat. Some bids are a single coat of epoxy with flakes on top.
- Stem walls. Often extra, sometimes skipped.
- A warranty with the exclusions written down.
Kits vs a pro floor
A big-box kit is thin water-based epoxy over an acid-etched slab. It looks good for a season. Summer tires, the afternoon sun through the door and monsoon grit find every weak spot, and grinding off a failed kit adds about $1.25 a sq ft to the next floor.
How to compare bids
- Ask every company how they prep: grind or etch.
- Ask what the base coat and the clear coat are made of.
- Ask for the square footage they priced.
- Ask for the warranty in writing, exclusions included.
- Ask who will be there on install day.
