Floor area in, kits and cost out — DIY breakdown and pro installed price side by side. Then send it straight into a quote.
Ballpark, not gospel. Kit coverage and pro rates vary by product and region — verify with your supplier before quoting.
Straight answers, no fluff. Then run your own numbers above.
DIY with quality kits runs $500–$1,000 for a 400–500 sq ft garage. Pro-installed epoxy costs $3–$12 per sq ft — $1,500–$5,000+ for the same garage — depending on prep work and coating system.
Divide your square footage by the kit's coverage (usually 200–300 sq ft). A 450 sq ft garage needs 2 kits at 250 sq ft coverage. Buy the same batch for color consistency.
Pro-installed 100% solids epoxy lasts 10–20 years with normal use. DIY water-based kits last 2–5 years. Prep is everything — grinding beats etching every time.
Stains need degreasing and etching first; cracks need filling. Oil-soaked concrete may never bond properly — that's when you quote a grind-and-seal or a polyaspartic system instead.
