How much does epoxy garage floor coating cost in New Brunswick?

Professional epoxy garage floor coating in New Brunswick costs $4–$8 per square foot installed, putting a standard two-car garage (400–500 sq ft) in the $1,600–$4,000 range. DIY epoxy kits available at NB hardware stores cost $150–$400 in materials for the same area — but the results and longevity differ considerably.

Professional coating systems use commercial-grade two-part epoxy or, increasingly, polyaspartic coatings that are more durable and cure faster. The labour-intensive part is surface preparation: the concrete must be mechanically ground (not just acid-etched) to open the surface pores and ensure proper adhesion. Without adequate surface prep, epoxy peels within months. Professional crews use floor grinders and apply multiple coats — a base coat, colour flakes (optional), and a clear topcoat. The result is a seamless, durable surface that resists oil, salt, and abrasion.

NB garages create specific challenges for epoxy coatings. During winter, vehicles bring in salt-laden slush from NB roads, and that chloride-rich water sits on the garage floor while cars drip. Salt attacks epoxy coatings from below when moisture in the concrete drives upward pressure (hydrostatic vapour). New concrete must cure for at least 30 days before any coating is applied — many homeowners make the mistake of coating a new garage floor immediately and the coating bubbles and peels.

Polyaspartic coatings ($6–$12 per square foot professionally installed) are now the preferred choice over traditional epoxy for NB garages because they cure in hours rather than days, handle temperature extremes better, resist UV yellowing, and are less susceptible to moisture vapour transmission. The higher upfront cost is generally worth it for a garage floor that will see NB winters year after year.

DIY epoxy kits are a reasonable option for homeowners who are meticulous about surface preparation and have a dry, warm (above 15°C) week for application and cure. Read the moisture test instructions on the kit — applying over a damp slab is the single biggest cause of peeling.
