How much does a garage floor coating cost in NJ?
These are our actual starting prices, the same numbers the instant estimate uses. No “starting at $2” that turns into $7 once someone shows up.
Price per square foot, by finish
| Finish | Per sq ft | Best for |
|---|---|---|
| Full flake | $5–$7 | Our most popular. Textured, hides dirt, slip-resistant. |
| Metallic / marble | $8–$12 | Deep, liquid, one-of-a-kind showroom look. |
| Solid color | $6–$8 | Clean and simple. Workshops, utility spaces. |
Every price includes diamond grinding, the base coat, the flake, metallic or color, the clear topcoat and clean-up.
What that means for a typical garage
| Finish | 1-car garage (~250 sq ft) | 2-car garage (~450 sq ft) | 3-car garage (~650 sq ft) |
|---|---|---|---|
| Full flake | $1,250 – $1,750 | $2,250 – $3,150 | $3,250 – $4,550 |
| Metallic / marble | $2,000 – $3,000 | $3,600 – $5,400 | $5,200 – $7,800 |
| Solid color | $1,500 – $2,000 | $2,700 – $3,600 | $3,900 – $5,200 |
Garage sizes vary. Measure length times width of the floor you want coated, or let the estimate do it from the garage size. There is no minimum job, so a small one-car garage is priced on its own square footage.
What adds to the price
- Crack repair: extra, priced on site based on the condition of the concrete.
- Pitting / spalling repair: $0.5–$1 per sq ft of affected floor.
- Oil-stain degreasing: $150–$300 per job.
- Remove existing coating / paint: $1–$2 per sq ft of affected floor.
- Slabs older than about 30 years: $0.25–$0.5 per sq ft for the extra grinding and patching they usually need.
- Outdoor work (patios, pool decks, porches): $0.75–$1.25 per sq ft for the extra prep and texture.
The biggest swing we see is an old coating or garage paint that has to come off first. If your floor has been painted or had a DIY kit on it, say so in the estimate.
Where the cheaper quotes come from
A lower number usually means one of three things: the floor is acid-etched instead of ground, which gives a weaker bond; there is no clear topcoat, so the flake wears and the color dulls; or it is a single thin coat that peels under hot tires. Ask what is included per square foot and whether the slab will be diamond-ground. If the answer is “we wash it,” that is the difference.
Common questions
What does a two-car garage floor cost in NJ?
With our current prices, a typical two-car garage of about 450 sq ft with a full-flake system runs about $2,250 to $3,150 before any repair work. Solid color and metallic cost more per square foot; the table below shows each. Crack repair is extra, priced on site.
Why do online prices for epoxy floors vary so much?
Because the cheap numbers usually leave out the grinding, crack repair and topcoat, or describe a one-coat DIY kit. Ask any installer what is included per square foot.
Is sales tax charged on a garage floor coating in NJ?
A coating installed as a permanent improvement to a home is generally treated as a capital improvement in New Jersey, which is documented with form ST-8. Tom confirms how it applies to your job on the proposal.
