What type of epoxy system works best for a restaurant kitchen in the ByWard Market

Best Epoxy System for ByWard Market Restaurant Kitchens

For a restaurant kitchen in Ottawa's ByWard Market, the best choice is a 100 percent solids epoxy base with a quartz broadcast and polyurethane topcoat — also known as a quartz epoxy mortar system. This combination delivers the slip resistance, chemical resistance, thermal shock tolerance, and cleanability that commercial kitchens demand. Budget $14 to $18 per square foot installed for a proper restaurant-grade system in Ottawa, which for a typical ByWard Market kitchen of 400 to 800 square feet puts the total project at $5,600 to $14,400.

Restaurant kitchens are among the most demanding environments for any floor coating. Your floor faces constant exposure to hot grease, acidic food spills, caustic cleaning chemicals, boiling water, and heavy foot traffic — often all in the same shift. A standard garage-grade epoxy will break down within months under these conditions. The quartz broadcast system works because the embedded quartz granules provide outstanding slip resistance even when wet with grease and water, which is critical for kitchen safety and meeting Ontario health and safety requirements. The quartz also adds substantial thickness and abrasion resistance to the system, typically bringing the total film build to 60 to 125 mils compared to 10 to 20 mils for a standard commercial epoxy.

Thermal shock resistance is a detail that many restaurant owners overlook. When a pot of boiling water hits a cold floor, or when a kitchen goes from cooking temperatures to a cold overnight shutdown — especially in a ByWard Market building where older construction and Ottawa's minus 30-degree winters create dramatic temperature swings — the coating must flex without cracking or delaminating. Polyurethane topcoats handle thermal shock far better than bare epoxy, which becomes brittle under rapid temperature changes.

For ByWard Market restaurants specifically, there are a few extra considerations. Many ByWard Market commercial spaces occupy older buildings with limestone foundations and aging concrete slabs that may have significant moisture issues. Moisture testing before coating is absolutely essential — you need a vapour emission rate below 3 pounds per 1,000 square feet per 24 hours. Older slabs may also require extensive crack repair and levelling before the coating system can be applied. Additionally, Ottawa Public Health inspects restaurant floors as part of their food safety assessments, so the finished surface must be seamless, non-porous, and easy to sanitize — all characteristics of a properly installed quartz epoxy system.

Installation timing matters for ByWard Market businesses. Most contractors can complete a restaurant kitchen floor in 3 to 5 days, but full cure requires 5 to 7 days before heavy traffic. Many restaurant owners schedule the work during a planned closure or renovation period. Look for flooring contractors experienced in food-service environments through the Ottawa Construction Network directory at justynrookcontracting.com — commercial kitchen floors require specialized knowledge that not every epoxy installer has.
