What Is Urethane Cement Flooring?
Urethane cement — also known as polyurethane mortar or cementitious urethane — is a three-component floor coating system consisting of a polyol resin, an isocyanate hardener, and a Portland cement aggregate. The cement component is what distinguishes this system from standard liquid coatings: it produces a mortar-like consistency that can be trowel-applied to thicknesses of 4–9mm, creating a floor system that behaves more like a reinforced concrete topping than a surface coating.
The combination of polyurethane chemistry with Portland cement aggregate produces a coating system that is fundamentally different from epoxy in its thermal, mechanical, and moisture-handling properties. Where epoxy is a relatively rigid, thermally sensitive material, urethane cement is elastomeric, thermally stable from -40°C to +120°C, and moisture-tolerant during application — meaning it can be applied to green concrete or damp substrates where epoxy installation would fail.
At ProEpoxy, we install urethane cement in the commercial environments where standard epoxy simply cannot perform: commercial kitchens, food processing facilities, breweries, pharmaceutical plants, and cold storage facilities across Toronto and the GTA. These are environments where thermal shock from steam cleaning, boiling water discharge, or rapid temperature changes would crack or delaminate any standard epoxy system within months of installation.
Why Urethane Cement Outperforms Epoxy in Commercial Environments
The fundamental limitation of standard epoxy in demanding commercial environments is thermal expansion mismatch. Epoxy has a coefficient of thermal expansion significantly higher than concrete. When the floor surface experiences rapid temperature changes — boiling water discharge in a commercial kitchen, steam cleaning, hot equipment spills — the epoxy expands faster than the concrete slab below it. This creates shear stress at the bond line. Over hundreds of thermal cycles, the stress accumulates and the coating delaminates. It is not a matter of if — it is a matter of when.
Urethane cement's thermal expansion coefficient is much closer to that of concrete. The cement aggregate in the mixture physically ties the chemistry to the concrete matrix, reducing the differential movement at the bond line. Combined with the elastomeric flexibility of the polyurethane binder, this produces a floor system that handles thermal cycling — including sudden temperature changes from -20°C cold storage to +80°C steam cleaning — without delaminating.
Additionally, urethane cement is inherently more moisture-tolerant than epoxy. Standard epoxy installations require the concrete moisture vapor emission rate (MVER) to be below a threshold — typically 3 lbs/1000 sq ft/24 hours — or a moisture mitigation primer must be applied. Urethane cement can be applied over substrates with significantly higher moisture content, making it suitable for basement commercial kitchens, facilities with water tables, and situations where concrete drying time cannot be accommodated.
Ontario Regulatory Compliance for Food-Service Floors
Ontario's Food Premises Regulation 493/17 requires that food premises floors be constructed of materials that are smooth, non-absorbent, easy to clean, and in good repair. For environments where food is prepared or processed, the floor must be seamless (no grout lines, no tile joints), impervious to liquids and microbial penetration, and capable of withstanding the cleaning chemicals and temperatures used in commercial sanitation protocols.
Standard tile with grout joints fails this requirement — grout is porous, harbours bacteria, and cannot be sanitized to food-safety standards. Standard epoxy can meet the requirement when freshly installed, but thermal shock cycling and chemical attack from cleaning agents degrade it over time, creating micro-cracks and surface damage that compromises the seamless, impervious requirement.
Urethane cement installed as a seamless, troweled system meets the Ontario Food Premises Regulation 493/17 requirements and maintains that compliance through years of commercial kitchen operation. The surface can be steam-cleaned, treated with commercial sanitizers including quaternary ammonium compounds, and exposed to hot water rinses without degradation. Where required, we also install anti-slip aggregate and integral coved base to complete the health code compliant floor system.
Thermal Shock Resistance: -40°C to +120°C
The thermal performance specification that separates urethane cement from every other floor coating system is its resistance to thermal shock across a range of -40°C to +120°C. In practical commercial terms, this means the floor can handle: cold storage that drops to -30°C or colder; boiling water or steam discharge at 100°C+; immediate transition from one to the other without cracking, debonding, or surface damage.
This is not an incidental property — it is the primary reason food processing facilities, breweries, pharmaceutical production spaces, and cold-chain logistics facilities specify urethane cement as their floor coating system. The floor will not fail from thermal cycling. It is designed for the environment.
Ideal Applications for Urethane Cement in Toronto
- Commercial kitchens and restaurant kitchens: Steam cleaning, hot water discharge, grease, and cooking acids make commercial kitchens the most demanding floor environment in the hospitality industry. Urethane cement is the correct coating — epoxy is not.
- Food processing plants: High-pressure water washing, strong sanitizing chemicals, thermal cycling from production equipment, and USDA/NSF inspection requirements all point to urethane cement as the standard specification.
- Craft breweries and beverage production: Wort spills, cleaning-in-place (CIP) chemical exposure, CO2, and constant hosing make breweries extremely aggressive floor environments. Urethane cement with coved base detailing is the industry standard.
- Pharmaceutical and laboratory facilities: Chemical resistance to solvents, acids, and pharmaceutical compounds, combined with seamless cleanability and NSF compliance, make urethane cement the preferred specification for pharma production floors.
- Cold storage and refrigerated warehouses: Thermal cycling from ambient to refrigerated temperatures and the condensation patterns in cold storage environments require a coating with urethane cement's flexibility and moisture resistance.
- Meat processing and protein facilities: Blood, organic acids, and aggressive cleaning protocols in protein processing environments require maximum chemical resistance and seamless surface integrity.
Slip Resistance and Anti-Slip Options
Wet commercial kitchen and food processing floors are a significant workplace safety hazard — and one of the leading causes of WSIB claims in the Ontario food service industry. Urethane cement troweled finishes naturally produce a textured surface with meaningful wet slip resistance, but for environments with continuous water, oils, or other slippery substances, we offer enhanced anti-slip aggregate options.
Aluminium oxide or silicon carbide aggregate can be incorporated into the urethane cement topcoat at broadcast rates calibrated to the specific environment. These aggregates produce a durable, high-grip surface that retains its slip resistance through repeated cleaning cycles — unlike surface-applied anti-slip treatments that wear off over time. We specify slip resistance to the relevant section of the Ontario Occupational Health and Safety Act and can provide SCC (Slip Coefficient of Compliance) documentation on request.
Coved Base Installation for Health Code Compliance
Health codes and food safety regulations in Ontario require a seamless, sanitary cove detail at the floor-to-wall junction in food preparation areas. Standard square floor-to-wall transitions trap debris, moisture, and bacteria in the joint, creating a chronic sanitation problem that cannot be resolved by cleaning alone.
Our urethane cement installation includes integral coved base detailing — a rounded, seamless transition from floor to wall installed as part of the same urethane cement system. The cove is typically 100–150mm in height and is formed using urethane cement mortar against a pre-formed backing rod. When complete, there is no joint, no edge, and no debris trap at the floor-to-wall junction. The entire assembly — floor field plus coved base — is a single, continuous, seamless surface that can be cleaned and sanitized to food-safety standards.
Installation Process: How Urethane Cement Is Different from Epoxy
Urethane cement installation follows a different process than standard epoxy, with key differences at the surface preparation and application stages.
- Surface preparation: Shot blasting or diamond grinding to ICRI CSP 5–7 — a more aggressive profile than standard epoxy installation, because the thicker urethane cement mortar requires more surface texture for mechanical keying.
- Moisture tolerance: Unlike epoxy, urethane cement can be applied to concrete with surface moisture present — an important advantage in many commercial kitchen and food processing installations where the floor cannot be fully dried before coating.
- Mixing and application: Three-component mixing (polyol, isocyanate, cement) is done on-site with controlled ratios. The mixed mortar is trowel-applied in a single pass to specified thickness (typically 4–6mm for floor field, 6–9mm for coved base).
- Cure time: Urethane cement achieves foot traffic in approximately 12–16 hours and full chemical resistance in 7 days. This is faster return-to-service than many floor systems for commercial applications requiring minimal downtime.
- Topcoat options: Urethane cement can be installed with or without a liquid topcoat. A clear polyurethane or polyaspartic topcoat is often applied to enhance gloss, reduce porosity, and improve chemical resistance for particularly aggressive chemical environments.
Urethane Cement Flooring Cost in Toronto
Urethane cement installed in Toronto commercial facilities typically ranges from $8 to $15 per square foot, depending on the system thickness, anti-slip requirements, coved base linear footage, and the extent of surface preparation required. This is the premium end of the commercial flooring range — but it is the correct specification for demanding environments. Facilities that install the wrong product to save money on the initial installation typically pay more in total cost of ownership through repeated repairs and premature replacement of inadequate coatings.
