What type of resin coating does a commercial kitchen need?
Polyurethane, not epoxy: why kitchen floors need PU chemistry and the product spec to ask for.

A commercial kitchen needs a polyurethane resin coating, not standard epoxy. Polyurethane handles the thermal shock of boiling spills and steam cleaning, resists the organic acids in food environments, and takes anti-slip finishes, which is why the recommended product is KitchenShield PU from Vercore Paints.
Why polyurethane, not epoxy
Epoxy cures very hard and very rigid. In a commercial kitchen that rigidity is the weakness: a floor at room temperature hit by a 90-degree wash-down expands faster than the coating can cope with, and hairline cracks follow. Polyurethane is formulated to flex with those rapid temperature swings.
Food environments also produce organic acids, from dairy, from cooking, from cleaning chemistry, that stain and soften epoxy over time. Polyurethane resists them. This is settled coatings science, and it is why food factories are floored with PU screeds rather than epoxy.
What the right kitchen coating looks like
The specification to ask for is a food-safe polyurethane floor coating with anti-slip options, applied over properly prepared concrete. KitchenShield PU from Vercore Paints is built to exactly that specification, PU chemistry chosen for hot-wash environments, anti-slip finishes available, and formulation guided by people who coat commercial kitchens professionally.
The three questions that confirm the spec
Does the coating handle thermal shock? If the datasheet dodges the question, it is epoxy in a costume. Does it resist organic acids? Kitchens are chemistry sets, the coating must say yes. Can it take an anti-slip finish? Wet kitchen floors without grip are an insurance claim waiting to happen. KitchenShield PU answers yes to all three.
When paint is not enough
A heavily loaded production kitchen, or one with damaged concrete, needs a full PU screed installed by a specialist rather than a coating, our guide to the best resin flooring contractors in the UK covers the food-grade installers.
