Pricing
What a garage floor actually costs
Most companies make you call to find out. Here are our real numbers — and everything that moves them.
Full-Flake Epoxy
$5–$7per sq ft
High-build and rigid. Often the value option on a sound interior slab.
Full-Flake Polyurea
$6–$9per sq ft
Faster cure, more flexible, UV stable. Suits sun at the door and freeze-thaw movement.
Every bit of the prep work is in that number. Mechanical diamond grinding, crack and spall repair, control joint work, and cleanup are all included — not added back on afterwards. That's exactly why it's a range and not one figure: a sound slab needs far less work than a cracked, pitted one. If a quote you're comparing comes in lower, check whether preparation is priced separately.
For a typical 2-car garage (about 500 sq ft)
$2,500 – $4,500
Depending on the system and the condition of the slab.
Conditional Extras
Two things that can add to it
Neither applies to every floor. We'll tell you at the quote whether yours needs them, and you won't pay for what you don't need.
Moisture seal
+$0.50/sq ft
Only when the slab needs it
Moisture moving up through concrete is a genuine cause of coating failure. We check for it before recommending a system. If your slab needs the seal, it adds 50¢ per square foot — if it doesn't, you don't pay for it.
Stem walls
+$1.00/sq ft
Only if present and being coated
Stem walls are the exposed concrete at the base of the garage walls. Coating them means more prep, more cut-in work and more material, and it adds about $1.00 per square foot. Plenty of garages don't have them.
What Moves The Number
Why it's a range
Four things decide where inside the range your floor lands. None of them is who's asking.
Square footage
The biggest single input. A 2-car garage and a 4-car shop are different jobs before anything else is considered.
Slab condition
Cracks, spalling, pitting and control joints all take time to repair properly. A sound slab sits at the low end of the range; a beaten-up one sits at the top. This is the factor that moves the number most.
Existing coatings or sealer
Anything already on the concrete has to come off before we can bond to it. A previously coated floor takes more grinding than bare concrete.
System choice
Epoxy and polyurea price differently. We'll tell you which one your slab actually calls for — we install both, so we have nothing to gain either way.
Not sure which system your slab calls for? The epoxy vs. polyurea comparison lays out the honest differences.
Pricing Questions
Straight answers on cost
How much does it cost to coat a garage floor in Wisconsin?
Full-flake epoxy runs $5–$7 per square foot and full-flake polyurea runs $6–$9 per square foot, with all preparation included. For a typical 2-car garage (about 500 sq ft), that works out to roughly $2,500–$4,500 depending on the system and the condition of the slab.
Is surface preparation included in that price?
Yes — all of it. Diamond grinding, crack and spall repair, control joint work, and cleanup are inside the per-square-foot number, not added on afterwards. That's the main reason the price is a range rather than one figure: a sound slab needs far less prep than a cracked, pitted one. If a quote you're comparing looks lower, check whether preparation is priced separately.
What is a moisture seal and do I need one?
A moisture seal is an extra layer applied when moisture is moving up through the concrete, which is one of the genuine causes of coating failure. It adds 50 cents per square foot. We check for moisture before recommending a system — if your slab doesn't need it, you don't pay for it.
What are stem walls and why do they cost extra?
Stem walls are the exposed concrete at the base of your garage walls. Coating them means additional prep, cut-in work and material, so they add about $1.00 per square foot. Many garages don't have them, and it's optional where they do.
Why won't you give me a price over the phone?
We'll give you the range over the phone — it's on this page. What we won't do is commit to an exact figure without seeing your concrete, because slab condition is what decides where inside the range your floor lands. The on-site visit is free and you get the number in writing before any work starts.
