The Complete Contractor Guide to Pricing Epoxy & Polyaspartic Floors Per Sq.Ft.
Why do busy 1-rig installers work 60 hours a week yet end the season with an empty bank account? Because most calculators ignore the 6 hidden costs of concrete coating.
1. Why You Must Charge for Your Warranty
Resin manufacturers only warrant liquid defects in the bucket—never hydrostatic moisture vapor, hot-tire pickup, diamond segments, or your crew's labor to strip and recoat a 400 sq.ft. 2-car garage. Setting aside 3%–5% of every jobbuilds a dedicated self-insurance pool so honoring a 10-year warranty never wipes out a week's pay.
2. Equipment Servicing, Insurance & Winter Days
Planetary grinders eat bearings, belts, dust skirts, and metal-bond diamonds, while commercial truck/trailer policies and heated resin storage bill 12 months a year—even when snow shuts down unheated garages. Divide 12 months of overhead by realistic billable days (140–150 days in Canada/Northern US, not 365).
3. Charging Market Price to Fund Expansion
Smaller shops pay higher per-kit prices than pallet buyers, while larger fleets carry heavier overhead—which is why GTA & major metro market prices settle around $7.00–$9.50/sq.ft. Charging healthy market rates and allocating 6%–10% annually to marketing and equipment is the only mathematical path off a single grinder.
