Why wine is hard on floors
Wine sits around pH 3.5, and its tartaric and malic acids etch the paste layer of bare concrete while the pigment follows the acid in, which is why untreated crush pads carry purple halos around every drain. Then the cleaning cycle swings the other way: caustic clean-in-place chemistry after every run. Ordinary epoxy clears dull and soften under that alternation, so the topcoat specification is where a winery floor is really decided.
The production spec
Crush pads, cellars and bottling lines take a double-broadcast quartz system with a novolac or urethane topcoat: seamless, 1/8" to 1/4" thick, slip-textured for wet boots, turned up the wall as an integral cove and detailed into the drains rather than stopped at their edges. Falls matter as much as chemistry, wash-down water has to reach the trench drain without ponding, and on older slabs re-cutting the falls is part of the job.
Where urethane cement earns its premium
Any zone that takes genuinely hot water, steam sanitising, hot caustic, wash-down near the boiler, wants urethane cement rather than an epoxy-based build. Its thermal expansion is close to the concrete below it, so the hot-cold cycling that shears standard epoxy off a slab simply flexes through it. It prices at the top of the commercial range and is cheaper than replacing an epoxy floor twice.
The tasting room answer
Front of house has the opposite priorities: hospitality, not wash-down. Polished concrete is the default, architectural, cool underfoot through an Okanagan summer, immune to UV through the south glazing most tasting rooms carry, and protected by a penetrating guard that lets spilled reds mop off. Metallic epoxy is the upgrade where the room itself is part of the brand.
When to book it
Production floor work takes three to five days including cure, and the window that absorbs it is January through June, after the vintage is bottled and before the next one arrives. Booking against harvest is how wineries end up living with a failing floor for another full year.
