Cost by garage size
Square footage drives price more than anything else. Here's how common Treasure Valley garage sizes tend to price out for a full-broadcast flake floor:
- 1-car garage (~250 sq ft): about $1,200–$2,200 — small jobs cost more per sq ft because setup and equipment are the same
- 2-car garage (~400–480 sq ft): about $2,000–$4,000
- 3-car garage (~600–750 sq ft): about $3,200–$6,500 — common in newer Meridian, Eagle, Kuna and Star homes
- Shop or RV garage (1,000+ sq ft): often toward the low end per sq ft — see shop & RV floors
For a worked example with 400 sq ft, 24x24 and 1,000 sq ft floors, read what a 2-car garage costs to epoxy in Boise.
What changes the price
- Coating system: solid epoxy < flake epoxy < polyaspartic < metallic
- Concrete condition: cracks, spalling near the door, oil-soaked areas and old paint or epoxy all add prep time
- Moisture: slabs with high moisture vapor need a mitigating primer
- Stem walls: coating 4–6 inches up the walls gives a finished look and adds cost
- Topcoat: thicker or UV-stable polyaspartic topcoats cost more but last longer in sunny garages
- Access and clearing: we quote assuming the garage is emptied; help with moving items can be arranged
Watch for low quotes that skip grinding. The cheapest bids often acid-etch or just clean the floor and roll on a thin coat. That's where peeling under hot tires comes from. Ask every installer how they prep the slab — see concrete repair & prep.
DIY kit vs professional install
Big-box epoxy kits in Boise stores run roughly $120–$450 for a 2-car garage, and multi-part 100%-solids or polyaspartic kits can run $1,000 or more in materials. Add grinder rental, crack filler, flake and a weekend or two of labor. DIY can work on a sound slab if you rent a grinder — but most failed floors we hear about were kits rolled over unground concrete. Full comparison: DIY epoxy kit vs professional.
Cost FAQ
What is the average cost to epoxy a 2-car garage floor in Boise?
A typical 2-car garage is roughly 400–480 sq ft. At typical Treasure Valley prices that's about $2,000–$4,000 for flake epoxy and about $2,400–$4,800 for a polyaspartic flake system. Solid-color epoxy can come in lower; heavy repairs add more.
How much would it cost to epoxy a 24x24 garage?
A 24x24 garage is 576 sq ft — larger than many 2-car garages. At $4.50–$8 per sq ft for flake epoxy, that's roughly $2,600–$4,600, or about $3,200–$5,800 for polyaspartic flake. Your exact price depends on concrete condition and the system.
How much does 1,000 sq ft of epoxy cost?
Larger floors usually come in toward the lower end of per-square-foot ranges. As a rough guide, 1,000 sq ft of flake epoxy might land around $4,500–$8,000, and solid-color epoxy around $3,000–$6,000, before heavy repairs.
Is there a minimum job price?
Most installers have a minimum because grinding equipment, materials and setup cost the same on a small floor. Small spaces like a single-car garage or a laundry room often cost more per square foot than a large garage. We'll be clear about this at your estimate.
What's included in the price?
Our quotes include diamond grinding with dust extraction, minor crack and chip repair, base coat, flake or color, clear topcoat, and cleanup. Heavy spall repair, old coating removal, stem-wall coat-up and moisture mitigation are itemized separately so you can see exactly what you're paying for.
