Concrete polishers: per-sqft quotes that price the finish, the prep, and the passes. Free, no signup.
Starting point. Flat $/sq ft quotes die here: a gloss finish takes far more passes than grind and seal. Adjust for your machine and concrete.
Concrete polishing dies on the flat per-square-foot quote. A $4 number looks fine until the finish tier, the coating removal, the crack repair, and the passes multiply the hours. Start with your bar (75), profit margin percent (20), minimum job fee ($500), and weekly take-home goal ($3,000). Pick a finish preset: Grind and seal, Honed 800, or Polish 3000, each filling square footage, grind minutes per square foot, diamond tooling, densifier, and sealer as editable starting points. A gloss finish takes far more passes than grind and seal, and the presets reflect that. The prep card prices what nobody prices: old coating removal as a checkbox with extra minutes per square foot, crack repair in linear feet with cost and minutes per foot, and flat patching. The materials card takes tooling, densifier, and sealer cost per square foot plus equipment wear. Results show the breakdown, the recommended quote (the greater of the minimum fee and true cost times one plus margin, rounded up to $25), dollars per square foot, effective hourly rate, and the verdict. The gut check grades your instinct price per square foot, and the week planner turns the goal into jobs.
Example only, not typical pricing. Honed 800 defaults at a $75 bar with 20 percent margin: 800 square feet at 1.6 minutes each = 1,280 grind minutes; 30 feet of cracks at 3 minutes each = 90 minutes; 40 drive plus 90 setup. Own time is 1,500 minutes = 25.0 hours. Materials: tooling 800 x $0.35 = $280, densifier $200, sealer $160, equipment $100, crack materials $195; vehicle 30 x $0.67 = $20.10. True cost = 25 x 75 + $955.10 = $2,830.10. Recommended quote = ceil(2,830.10 x 1.20 / 25) x 25 = $3,400, or $4.25 per square foot. Effective rate = (3,400 - 955.10) / 25 = $97.80 per hour, above the bar, so the verdict is PRICED RIGHT. A $4 per square foot gut quote pays $89.80 per hour and leaves $200 on the table. The week planner turns a $3,000 goal into 5.3 jobs at $569.90 profit each, 131.6 hours, and flags it: over 50 hours a week.
Why does the finish tier change the minutes per square foot?
Because each tier adds passes. Grind and seal presets start at 0.6 minutes per square foot; Honed 800 runs 1.6; Polish 3000 runs 3.0. The presets set tooling and densifier too, and you adjust for your machine and concrete.
How is crack repair priced?
Two lines: materials are linear feet times cost per foot plus a flat patching amount; time is linear feet times minutes per foot at your bar. Both land in true cost and in the quote.
What triggers the coating removal line?
The checkbox. When it is on, square footage times extra minutes per square foot counts as prep labor at your bar. Old adhesive or epoxy is the job that turns a one-day grind into two days.
What does CLOSE, BUT LEAKING mean here?
The effective rate clears 80 percent of your bar but not the bar. The quote covers true cost, yet you are working under your own rate, usually because prep or materials ate the margin.
How does the week planner use my goal?
It divides your weekly take-home goal by profit per job, then multiplies by your committed hours per job. Over 50 hours and it warns that the goal needs a higher price or bigger jobs.
