How much does it cost to get an epoxy or polyaspartic coating on my garage floor in Ottawa?

Garage floor coating costs in Ottawa depend heavily on the type of coating you choose, the size of your garage, and the condition of the existing concrete. For a standard two-car garage around 400 to 500 square feet, you can expect to pay between $1,800 and $3,500 for a professional epoxy coating and between $2,500 and $5,000 for a polyaspartic coating.

Epoxy coatings are the more affordable option upfront. Most Ottawa contractors charge between $4 and $7 per square foot for a full epoxy system that includes surface preparation, a primer coat, the epoxy base, and a clear topcoat. The lower end of that range typically gets you a solid color finish, while adding decorative flake or metallic pigments pushes you toward the higher end. Material costs for a quality two-part epoxy system run around $1.50 to $3 per square foot, with the bulk of your bill going to labour and preparation work.

Polyaspartic coatings cost more, generally $6 to $10 per square foot installed, but they offer significant advantages for Ottawa homeowners. Polyaspartic cures much faster than epoxy, often in a single day, which means your car can be back in the garage within 24 hours instead of the three to five days epoxy typically requires. This matters in Ottawa because our coating season is already short, and losing your garage for nearly a week during shoulder season can be a real inconvenience.

The biggest factor that can push your cost up is concrete repair. Ottawa garage floors take a beating from freeze-thaw cycles and road salt, and most floors need at least some crack filling or spalling repair before any coating goes down. Minor crack repair might add $200 to $500, but if your slab has significant damage or moisture issues, repair costs can add $800 to $1,500 or more. A good contractor will diamond grind or shot blast the entire surface to create the mechanical profile the coating needs to bond properly, and that preparation step alone accounts for roughly 30 to 40 percent of the total job cost.

Some Ottawa contractors offer package pricing that bundles preparation, coating, and a decorative flake finish together. These packages typically run $2,200 to $3,000 for a two-car garage with epoxy or $3,500 to $4,500 with polyaspartic. Getting three quotes from local contractors is always worthwhile since pricing varies considerably across the Ottawa market. Be cautious of quotes that come in well below $1,500 for a two-car garage, as that usually means corners are being cut on surface preparation, and poor preparation is the number one reason garage floor coatings fail.
