The short answer: $5 to $7 per square foot installed
Arrowhead Coating Co. prices professionally installed Simiron polyurea and epoxy floor systems at $5 to $7 per square foot in the Springfield area. That's an installed price — grinding, crack and joint repair, base coat, decorative chip broadcast, polyaspartic topcoat, cleanup and the lifetime residential warranty are all inside it.
Where you land in that range depends mostly on slab condition and finish. A clean, sound, new slab with a standard chip blend sits at the bottom. An older slab with spalling, previous paint, cracked control joints or a metallic finish sits at the top.
- $5/sq ft — sound, uncoated slab, standard chip blend
- $6/sq ft — typical older slab with normal crack and joint repair
- $7/sq ft — heavy repair, old coating removal, coved edges, steps or premium finishes
What that means for a typical garage
Square footage is the biggest single factor, so it helps to work from real garage sizes. These are the dimensions we measure most often in Greene and Christian County homes.
- One-car garage, about 12 x 22 ft (264 sq ft) — roughly $1,300 to $1,850
- Two-car garage, about 20 x 22 ft (440 sq ft) — roughly $2,200 to $3,100
- Three-car garage, about 30 x 22 ft (660 sq ft) — roughly $3,300 to $4,600
- Large shop or detached building, 1,000+ sq ft — $5,000 and up, with better per-foot pricing at volume
What actually moves the price
Two garages the same size can quote differently, and it's almost always one of these five things.
- Slab condition — spalling, pitting, oil saturation and cracked control joints all add prep labor
- Existing coatings — old paint or a failed epoxy kit has to be ground off completely, not covered
- Finish choice — a standard chip blend costs less than a full metallic polyaspartic pour
- Extras — coved edges, coated steps, thresholds and door transitions add material and time
- Access and size — small, tight or awkward spaces cost more per foot than open ones
Why a DIY kit isn't the cheaper option
A big-box epoxy kit for a two-car garage runs a few hundred dollars, which looks like an enormous saving until you account for what it doesn't include. The kit relies on acid etching instead of diamond grinding, so the coating bonds to the surface skin of the concrete rather than an opened profile. On a hard-troweled Springfield-area slab that bond usually fails within a season or two, first as hot-tire pickup and then as sheet peeling.
The expensive part isn't the failure — it's the removal. Grinding a failed DIY coating off before a real system can go down adds labor to the eventual professional job. Paying $5 to $7 per square foot once is generally cheaper than paying for a kit, a weekend, and then full prep plus the professional install.
How to get a firm number
We don't quote garage floors over the phone beyond the range above, because the slab decides the price. An on-site visit takes about twenty minutes: we measure, check moisture, look at the cracks and control joints, note any previous coating, and talk through finishes. You get a firm written price before anything is scheduled, and the estimate is free.
