Industries — Commercial Kitchens
Commercial kitchen and restaurant flooring
No floor in a commercial building works harder than a kitchen floor. It is soaked from prep to close, hit with oil at fryer temperature and water near boiling, scrubbed with aggressive chemistry every night, and expected to be dry, safe and inspection-ready by morning. Tile grout gives up first; painted concrete never had a chance; and ordinary epoxy — the product most often sold into kitchens — has a documented failure mode called thermal shock that shows up precisely where the hottest water meets the floor.
The system that survives this room is urethane cement: a dense, trowelled mortar that tolerates heat, moves with the slab, and carries a cove up the wall so the whole floor washes down as one sealed surface. It is what we propose for wet, hot kitchens, and we will tell you plainly when a cheaper system is honestly enough — a dry storage room does not need the same floor as the dish pit.
The failure everyone has seen
Heat, water and the wrong chemistry
The typical kitchen flooring failure is not mysterious. Hot liquid hits the floor and the coating surface expands while the concrete an inch below stays cool. The two materials are bonded, one is moving and one is not, and the stress lands on the bond line. Cycle it twice a day for a year and the coating releases — usually first at the fryer line, the dish pit and around the drains, exactly the places the floor matters most.
Urethane cement resists this because its thermal behaviour is closer to concrete's, and because it goes down as a thick mortar rather than a thin film. The same properties carry it through steam cleaning, organic acids from food waste, and the quaternary and caustic cleaners used in nightly sanitation. Manufacturer lines we install — including MAPEI's Mapefloor CPU range — publish service temperature limits per system, and the specification is checked against how your kitchen actually operates, not against a brochure kitchen.
The floor is only part of the assembly. The cove base, the falls to the drains, the sealing at door thresholds and the detailing around equipment legs decide whether the room passes inspection and stays dry underfoot. A perfect floor with a failed junction is still a failed floor — how the resin chemistries compare more broadly is in our coating systems library.
Working around service
Installed between close and prep
Restaurants do not close for flooring, so the flooring works around the restaurant:
- Assessment during service hours.
We see the kitchen working — where water actually goes, which zones take heat, where the slab ponds — before anything is specified. Substrate moisture is measured at the same time.
- Zoned overnight installation.
The kitchen is sectioned so cooking capacity is never fully lost. Fast-setting urethane cement systems are designed for return to service within tight windows, conditions permitting. Where the window is tighter still, MMA cures in about an hour.
- Preparation despite the schedule.
Overnight work is not an excuse to skip grinding. The old coating comes off, the substrate is profiled, and repairs go in before the mortar — compressed hours change the sequence, not the standard. See surface preparation.
- Coving, falls and details.
Cove base trowelled at the walls, falls corrected toward the drains, thresholds and equipment plinths sealed. The details are the hygiene case.
Questions we get asked
Kitchen flooring FAQs
Why do epoxy floors fail in commercial kitchens?
Thermal shock. A fryer drained toward a floor drain, a steam kettle emptied, or a nightly hot-water wash-down heats the coating surface far faster than the concrete beneath it. Epoxy and concrete expand at different rates, and the repeated cycling breaks the bond. Urethane cement moves more closely with the slab, which is why it is the standard specification in wet, hot kitchens.
Can a kitchen floor be replaced without closing the restaurant?
In most cases the work runs overnight between close and prep, in sections, with equipment moved zone by zone. Fast-setting urethane cement systems are formulated for exactly this window. The sequencing is planned at assessment around your service hours and your health inspection schedule.
What is coving and why does it matter?
A cove is the floor material carried up the wall base in a curve, eliminating the 90-degree seam where water sits and bacteria harbour. Health authorities look for a cleanable, sealed floor-to-wall junction, and a trowelled cove in the same material as the floor is how a resin floor provides it.
Do you slope floors to the drains?
Falls to drain are built with the mortar underlayment where the existing slab ponds. A kitchen floor that drains fully is a safety feature as much as a hygiene one — standing water is the slip hazard, not the floor finish itself.
