If you run a kitchen anywhere in Jefferson County, the floor is part of what gets inspected. This is not a legal guide and your local health department is the authority on your specific premises, but the recurring themes are consistent and they shape the specification.
The underlying principle
Food safety codes generally require floors in food preparation areas to be smooth, durable, non-absorbent and easily cleanable.
Each of those words does work.
Smooth means no crevices for debris to sit in. Not glossy, which would be a hazard, but without gaps and joints.
Durable means it survives the environment rather than breaking down and shedding into food areas.
Non-absorbent means grease, blood and water do not soak in.
Easily cleanable means it can actually be washed properly, which is where coving comes in.
Coved bases, which is the one that catches people
The junction where the floor meets the wall is the single most scrutinised detail on a kitchen floor.
A square junction creates a corner where water, grease and food debris collect and cannot be reached properly by a mop or a squeegee. It is also where a floor covering terminates, and terminations lift.
A coved base turns the floor material up the wall in a curve, typically a few inches, so there is no junction at all. The floor and the wall base become one continuous surface, and the whole thing can be hosed and squeegeed.
Urethane cement and resin systems cove naturally, being laid in place. This is one of the strongest arguments for a resin floor over tile in a kitchen.
Drainage and falls
Water has to reach the drain. A floor that ponds is a floor that grows things.
Two problems come up repeatedly in existing kitchens. The slab was never laid to adequate fall, or equipment and fit-outs have changed since it was, so the falls no longer make sense for the current layout.
A thin coating cannot fix this, because it follows the profile of what is underneath. Urethane cement can, because it is laid thick enough to be graded and screeded to falls. That is frequently the real reason to choose the system rather than a coating.
Drain terminations matter too. The floor has to be cut in around drains and gullies with a proper mechanical key, not butted up to them. It is one of the most common failure points in cheap installations.
Slip resistance
A wet, greasy kitchen floor is one of the more dangerous surfaces in any workplace.
Grip comes from aggregate broadcast into the system at a specified grade. The balance is real: too smooth and it is a hazard, too coarse and it cannot be cleaned properly, which creates a hygiene problem instead.
Different zones justify different grades. The cook line and the dish pit want more than a dry storage room does.
Why urethane cement rather than epoxy
The specification driver in a kitchen is thermal shock rather than chemistry alone.
Boiling water, hot oil and steam cleaning hit the floor at high temperature. The surface expands instantly while the concrete underneath does not, and a rigid coating shears at the bond line and debonds.
Urethane cement has a coefficient of thermal expansion close to concrete's. It moves at roughly the same rate as the slab, so there is nothing to shear. It also tolerates a damper slab than epoxy will, which matters in an existing building where you cannot always get the concrete as dry as a datasheet wants.
It is applied considerably thicker and trowelled rather than rolled, and it looks like what it is: a functional industrial floor. Back of house, that is exactly right.
Zoning the specification
There is no reason to run the most expensive system across the whole premises.
The cook line, dish pit and anywhere near heat sources justify urethane cement. Dry storage, prep rooms away from heat, and walk-in surrounds can often take a high-build epoxy or a quartz system at lower cost, with the same coving and the same slip resistance where needed.
A sensible specification zones the building by exposure. That is a conversation worth having rather than accepting one product across the whole plan.
What existing floors bring with them
Most kitchen refits start with removal, and quarry tile on a thick mortar bed is the usual find in older premises.
That is a substantial job. Sometimes the bed comes out too, which changes both the price and the programme considerably. It needs to be in the quote rather than discovered on day one.
Vinyl sheet, old resin systems and layers from successive tenants all appear as well.
Working around service
Almost no kitchen can close for a week. Work gets phased by zone, typically overnight or across a closure day, with equipment moved and sections isolated.
Fixed equipment on legs can sometimes be worked around, though a floor cut around a fryer stand rather than laid under it leaves a joint where grease collects. Where it can be moved, it should be.
Some urethane cement systems return to service within hours, which is frequently what makes the schedule possible at all.

Common questions
Do we definitely need coved bases?
If you want a floor that can be cleaned properly at the wall junction, yes, and it is generally the first detail an inspector looks at.
Can we use epoxy instead? It is cheaper.
In dry areas away from heat, often yes. On the cook line and at the dish pit, thermal shock cracks rigid epoxy and urethane cement does not.
Our floor does not drain properly. Can that be fixed?
With urethane cement, yes, because it is laid thick enough to be graded to falls. A thin coating follows the existing profile and cannot correct it.
We have quarry tile. What is involved?
It comes up, often with the mortar bed. That is a substantial part of the job and it belongs in the quote rather than appearing as a variation.
Can we stay open?
Usually, phased by zone and out of hours. Fast return-to-service systems are often what makes it workable.
How slip resistant should it be?
Enough for a wet greasy floor, not so coarse it cannot be cleaned. Aggregate grade gets specified by zone rather than applied uniformly.
