What is the price per gallon for commercial-grade hundred-percent-solids epoxy in Ottawa?

Retail pricing for commercial-grade 100 percent solids epoxy by the gallon isn't really the right lens for evaluating your project costs in Ottawa — and here's why that matters for your budget planning.

How Epoxy Flooring Is Actually Priced in Ottawa

Commercial-grade 100 percent solids epoxy is sold through industrial coatings distributors, not retail hardware stores, and the product cost represents only a fraction of what you actually pay for a completed floor system. In Ottawa, contractors typically source from suppliers like Sherwin-Williams industrial division, Tremco, or specialized epoxy distributors. Raw material pricing for commercial-grade 100 percent solids epoxy runs roughly $80 to $200 per gallon depending on formulation, colour, and order volume — but that number is largely irrelevant to a homeowner planning a project.

A single gallon of 100 percent solids epoxy covers approximately 160 to 200 square feet at a standard application thickness of 8 to 12 mils. That sounds like a lot of coverage, but a proper floor system involves surface preparation, a primer coat, one or more body coats, decorative broadcast (if using flake or quartz), and a clear urethane or polyaspartic topcoat. Each layer has its own material and labour cost, and the preparation work — diamond grinding, crack repair, moisture mitigation — often costs as much as the coating materials themselves.

What actually matters for your budget is the installed cost per square foot. In Ottawa for 2025 to 2026, professionally installed 100 percent solids epoxy runs $6 to $12 per square foot for a standard garage floor. A typical two-car garage of 400 to 600 square feet therefore costs $2,400 to $7,200 fully installed, depending on floor condition, decorative choices, and whether moisture remediation is needed. Add a decorative vinyl flake broadcast system and a urethane topcoat, and you're comfortably in the $8 to $10 per square foot range for a high-quality residential finish.

Ottawa's climate adds real cost pressure here. Spring snowmelt and the city's high water table mean moisture vapour emission testing is almost always necessary before application. If a contractor finds elevated moisture — which is common in Ottawa basements and older garage slabs — a moisture-mitigating primer adds another $1 to $3 per square foot to the system cost. Skipping this step to save money is one of the most common reasons epoxy floors fail within the first year.

If you're trying to evaluate contractor quotes or understand whether a bid is reasonable, the per-square-foot installed price is the number to focus on. Three written quotes from different contractors will give you a much clearer picture of fair market pricing for your specific floor than the raw gallon cost ever could.

For browsing flooring contractors in the Ottawa area, the Ottawa Construction Network directory at justynrookcontracting.com is a free resource where you can find professionals who work with commercial-grade epoxy systems. Getting at least three quotes is always the right move before committing to any floor coating project.
