Pricing sources & methodology
Where the numbers come from
CoatQuote ships with US, 2026, installed national-average defaults so a contractor is calibrated on day one. Those defaults are benchmarked against the public contractor and cost-guide sources below, then handed to you as a starting point — not a fixed price.
All figures are US, 2026, installed national averages drawn from the sources on this page. They exist to seed a model, not to set your prices. Calibrate every number to your real material costs, crew production rates, and local market before you send a quote.
Per-square-foot system pricing
Installed $/SF ranges by coating system (solid, flake, quartz, metallic), used to seed per-SF mode.
| System | Benchmark installed range |
|---|
| Solid-color epoxy | $3–6 / SF |
| Decorative flake | $5–8 / SF |
| Quartz broadcast | $7–14 / SF |
| Metallic / designer | $8–15 / SF |
| Polyaspartic | $5–12 / SF |

Material coverage & spread-rate math
The cost-up engine converts coverage to material quantities using published product specs.
Manufacturer technical data sheets (TDS)
Published per-product: volume-solids %, recommended mil thickness, theoretical coverage (SF/gal)
Coverage, volume-solids, and waste factors come from manufacturer TDS for each product in your catalog — calibrate these to the exact products you buy.
Methodology
How these sources become the numbers in the tool.
We collect published installed-cost ranges and national averages across the sources above, take a defensible mid-2026 US national average for each system and prep tier, and load it as an editable default. The engine's job is the structure — coverage math, prep-tier resolution, and margin protection — not the price itself. Every figure is meant to be replaced with your real material costs, crew production rates, and regional multiplier before you send a quote.
