What is the price per square foot for a urethane topcoat on commercial epoxy in Ottawa

Urethane Topcoat Pricing for Commercial Epoxy Floors in Ottawa

A urethane topcoat applied over commercial epoxy flooring in Ottawa typically costs $2 to $5 per square foot as part of a new epoxy system, or $3 to $7 per square foot when applied as a standalone maintenance recoat over an existing epoxy floor. The price depends on the type of urethane, the number of coats, the condition of the existing floor, and the size of the project — larger commercial spaces benefit from economies of scale that bring the per-square-foot cost toward the lower end of the range.

There are two main categories of urethane topcoats used on Ottawa commercial floors, and the distinction matters for both performance and price. Aliphatic urethane is the standard commercial choice — it provides excellent UV resistance (it will not yellow under fluorescent or natural light), good chemical resistance, and a durable glossy or satin finish. Aliphatic urethane topcoats cost $2 to $4 per square foot for materials and application as part of a system install. Aromatic urethane is less expensive at $1.50 to $3 per square foot but will amber or yellow over time when exposed to UV light. Aromatic urethane is suitable for warehouses, mechanical rooms, and spaces without significant natural light, but should be avoided in retail, showroom, or office environments where appearance matters.

For a standalone recoat — applying a fresh urethane topcoat over an existing epoxy floor that is still in good condition — the cost runs higher per square foot because of the preparation work involved. The existing surface must be lightly abraded using a floor buffer with a maroon or green abrasive pad to create a mechanical bond for the new topcoat. Any damaged areas need spot repair first. The floor must be thoroughly cleaned and degreased. This preparation work adds $1 to $3 per square foot to the material and application cost, bringing the total for a maintenance recoat to $3 to $7 per square foot in Ottawa.

To put these numbers in context for common Ottawa commercial spaces: a 3,000-square-foot retail showroom getting a two-coat aliphatic urethane topcoat as part of a new epoxy system would add approximately $6,000 to $12,000 to the project cost. A 10,000-square-foot warehouse getting a single-coat aromatic urethane topcoat might add $15,000 to $30,000. A maintenance recoat on a 5,000-square-foot gym floor with surface preparation would run approximately $15,000 to $35,000.

The urethane topcoat is arguably the most important layer in a commercial epoxy floor system. It is the sacrificial wear layer that protects the more expensive epoxy beneath it. Without a urethane topcoat, the epoxy base coat is directly exposed to foot traffic, chemical spills, UV degradation, and abrasion — and once the epoxy is damaged, repair requires grinding and recoating the entire system. A urethane topcoat can be reapplied every 3 to 7 years at a fraction of the cost of a full floor system, effectively extending the life of your epoxy investment by decades.

Ottawa pricing for urethane topcoats tends to run 10 to 15 percent below Toronto rates for comparable products and application quality, reflecting lower commercial overhead costs in the Ottawa market. However, prices have increased approximately 8 to 12 percent since 2024 due to rising raw material costs for isocyanate-based products. Get a minimum of three quotes from commercial flooring contractors, and make sure each quote specifies the exact urethane product, number of coats, and mil thickness being applied.
