How much does a garage floor coating cost in Boise?

In the Boise area, professional garage floor coatings generally run $4.50–$8.50 per square foot for epoxy systems and $6–$12 per square foot for polyaspartic/polyurea systems. The spread comes down to the coating chemistry, how many coats, and the finish. Epoxy sits at the lower end; polyaspartic and polyurea cost more because the material is tougher, more flexible, UV-stable, and can be installed in cold weather. Decorative upgrades — full-broadcast color flake, metallic, or quartz — add to the per-foot price. These are general Treasure Valley ranges for planning, not a quote; the only way to price your floor accurately is to measure the slab and assess its condition.

Most standard two-car garages in the Treasure Valley are about 400–500 square feet, so a professional coating typically totals roughly $1,600 to $6,000 installed. A basic epoxy or single-coat flake floor lands near the bottom; a full polyaspartic flake system with thorough diamond-grinding and crack repair lands in the middle to upper range. Three-car and oversized garages scale up with the square footage, though the per-foot rate often drops a little on larger jobs because mobilization and prep are spread across more area.

Epoxy is the budget-friendly choice and looks great in the right conditions, but it's rigid, needs warmer temperatures to cure, and can yellow or get brittle over years of Idaho freeze-thaw. Polyaspartic costs more up front — usually a few dollars more per square foot — but it's more flexible, holds its color, and can be installed when it's cold, which is why it's the better long-term value for most local garages. Many quality floors combine the two: a strong base coat and a tough polyaspartic topcoat. Full comparison →

Many local installers offer financing or payment plans, and pricing is usually a flat, all-in quote rather than hourly. Ask about financing and payment-plan options when you request your quote. The best next step is a free on-site estimate so the number you get is firm — not a ballpark that changes on installation day.
