A seamless surface, so there are no joints or grout lines collecting grease, dust or product. It cleans with a mop instead of a scrubbing brush.
Enough thickness to take the traffic. A floor that sees pallet jacks and delivery trolleys every day needs more coating on it than a garage that sees one car.
And preparation that matches the load. Cracks get repaired rather than covered, and the slab gets prepared so the coating bonds into the concrete instead of sitting on top of it.
And a UV-stable polyurethane top coat, so shopfronts and anything near a window or roller door don't discolour.
