How to Price an Epoxy Garage Floor Job to Win the Bid and Still Profit

Most garage floor coaters underbid. Not by 5% — by 25-40%. They quote based on what they think the customer will pay rather than what the job actually costs to do right plus a real margin. The result: thin gross margins, no buffer for callbacks or warranty work, and a treadmill of needing more jobs to make the same money.

Here's the cost-plus framework that produces 45-55% gross margins on residential polyaspartic full-flake — and the communication moves that prevent price objections.

The cost-plus formula

Quote price should always equal: (Materials + Labor + Overhead Allocation) ÷ (1 − Target Gross Margin %). For a 50% gross margin target:

Most coaters don't do this math because they don't track their true job cost. They guess based on what feels reasonable, and they leave 20-40% on the table per job.

What goes into "job cost"

Materials

• Primer (epoxy or polyurea primer): $40-$80 per 2-car garage
• Color flake broadcast: $80-$180 depending on flake density (1/4" to 1" depending on system)
• Polyaspartic topcoat: $280-$420 per 2-car garage (the expensive ingredient)
• Concrete repair / patch (cracks, spalls): $20-$80 per job
• Diamond grinding pads (amortized): $30-$60 per job
• Misc consumables (rollers, brushes, tape, plastic, mixing tools): $30-$60 per job
• Materials subtotal: ~$480-$880 for a 2-car polyaspartic full-flake

Labor

• 2-person crew × 8 hours × $35/hour fully-loaded labor cost = $560 per crew-day
• Polyaspartic 1-day install = 1 crew-day = $560 labor
• Pure epoxy 2-3 day install = 2-3 crew-days = $1,120-$1,680 labor
• Labor subtotal for 2-car polyaspartic: $560

Overhead allocation — the forgotten 25%

Allocate to each job:

• General liability insurance: ~$8/job (assumes $4k/year, 500 jobs/year)
• Workers comp insurance: ~$25/job ($12k/year)
• Vehicle costs (lease, fuel, maintenance): ~$35/job
• Equipment depreciation (grinder, vacuum, ramp, etc.): ~$12/job (assumes 5-year amortization)
• Phone, software, payment processing: ~$15/job
• Admin time (scheduling, invoicing, follow-up): ~$45/job (1 hour @ $45/hour)
• Marketing allocation: $80-$200/job (depends on blended cost per acquisition)
• Overhead subtotal: $220-$340 per job

Total job cost for a 2-car polyaspartic full-flake: $480-$880 (materials) + $560 (labor) + $220-$340 (overhead) = $1,260-$1,780. At 50% gross margin target: quote $2,520-$3,560. At 55% margin: quote $2,800-$3,956.

The pricing communication that prevents objections

Most customer objections happen because the price feels like a number pulled from the air. Always frame your quote in terms of the variables that move it:

"For your 440-square-foot garage, polyaspartic full-flake runs $6-$11 per square foot installed depending on three things: condition of the existing slab (a few cracks add about $300, major spalling adds more), the flake density you want (standard 1/4 inch coverage vs full 1 inch which is denser visually), and whether you want a clear cove base treatment. Based on what I saw today, your job lands at about $7.50 per square foot, which is $3,300 for the whole garage."

This works because it shows the customer the math is real, not arbitrary. They can see what changes the price up or down. They feel respected as a buyer rather than pitched.

Common underbidding traps

• Quoting based on competitor pricing — your competitor might be losing money
• Forgetting drive time + load/unload time in labor calculation
• Not building in a contingency line for unexpected slab prep
• Skipping the overhead allocation entirely ("the truck is paid off")
• Discounting on the first call to "win the bid" — sets the wrong precedent
• Quoting before seeing the slab — moisture testing, cracks, spalling, condition all move price significantly
