What an epoxy or polyaspartic floor actually costs in Katy
We do not publish a per-square-foot rate, because the slab decides the price more than the size does. Here is the honest range and exactly what moves it.
Where most projects land
| Project | Most projects land between |
|---|---|
| Garage floor — flake system Indoor · 2-car through 3-car · most are 400–650 sq ft | $1,800 – $3,800 |
| Garage or interior floor — metallic system Indoor · same sizes · four coats, poured and worked by hand, two days on site | $4,500 – $7,500 |
| Patio, porch or outdoor area Most are 250–500 sq ft · moisture vapor barrier, double broadcast, UV-stable topcoat | $3,000 – $5,000 |
| Quartz — commercial and heavy-use areas Double broadcast · shops, utility rooms, locker and storage areas · most are 500–1,500 sq ft | $6,500 – $16,000 |
These are ranges for the sizes shown, not quotes. A small floor in rough shape can land above the range, and a large floor in good shape can land below it. Anything bigger than the sizes above — a four-car garage, a large outdoor kitchen, a pool deck — is quoted on its own. The only number that counts is the written one we hand you after inspecting your slab.
Why metallic costs more than flake
Same slab, same prep standard, different build. Three things drive the difference:
- Twice the coats. A flake floor is a base coat, a broadcast and a clear. A metallic floor is a primer, the pigmented metallic coat, and two clear coats over it.
- Two days instead of one. The metallic coat has to cure before the clear goes on, so the crew comes back. A flake garage is done in a day.
- It is worked by hand, and the slab has nowhere to hide. The metallic coat is poured and moved around by hand to create the pattern, which takes time and cannot be rushed. Flake also conceals minor slab imperfections; metallic shows every one, so the patching and prep underneath it has to be tighter.
No two metallic floors come out identical. That is the appeal, and it is also why we walk you through samples before you commit to it.
The four things that move your number
- Slab condition. Cracks, spalls, old paint and failing sealer all add prep and repair time. This is the single biggest swing, and it is why we will not quote from a photo alone on a rough floor.
- Moisture. A slab pushing moisture needs a vapor barrier underneath the system. Skipping it is the most common reason coatings bubble and peel a year later. We test for it instead of guessing, in three steps: an electronic moisture meter scan of the whole slab per ASTM F2659 to find the wettest areas, a sealed plastic sheet left on the slab per ASTM D4263 to indicate whether capillary moisture is present, then calcium chloride vapor emission testing per ASTM F1869 to measure how much is coming through. The results go in your written quote.
- System. Flake, metallic, solid color and quartz carry different material costs, and outdoor polyaspartic costs more than an interior build because of the barrier and the second broadcast.
- Access and layout. Obstacles, stairs, tight gates and anything we have to work around adds hours.
Why the cheap quote is cheap
If a bid comes in far under everyone else, something got left out, and it is almost always the prep. The usual shortcuts are acid etching instead of diamond grinding or shot blasting, skipping the moisture check, and burying crack repair as a change order once the equipment is already on site.
Ask every contractor three questions: how do you prepare the slab, do you test for moisture before you coat, and what exactly does the warranty cover. The answers will explain the price gap faster than any line item.
How we quote
- You send photos and rough measurements, or we come measure.
- We inspect the slab, check moisture, and note every repair it needs.
- You get a written price with the system, the warranty term and the repairs spelled out.
- Nothing changes after that unless you change the scope.
What the price includes
Every item below is in the number we quote. If a competitor's bid is lower, work down this list and ask which of these they left out.
- A slab inspection and three moisture checks before we price the job: an electronic moisture meter scan per ASTM F2659 to map the slab and find the wettest areas, a sealed plastic sheet per ASTM D4263 to indicate whether capillary moisture is present, and calcium chloride vapor emission testing per ASTM F1869 to measure the rate. The results go on your quote.
- Mechanical surface preparation to a CSP 2–3 profile by diamond grinding or shot blasting. No acid etching.
- Crack and joint repair, ground flush before coating.
- Edges cut in with a hand grinder and corners cut with triangular diamonds, so the profile runs wall to wall.
- All material and labor for the system quoted, including the moisture vapor barrier when the slab calls for one.
- Masking and protection of walls, doors, trim and anything adjacent.
- Daily cleanup and haul-off of our debris.
- A written warranty and a care guide at handover.
