Why the Wall Joint Is Worth Doing Properly
A standard floor stops at the skirting and leaves a thin gap behind it. Water finds that gap, so does dust, and over a few years so does everything else, and no amount of mopping gets it back out because your mop cannot reach into it. Coving removes the gap rather than sealing it, which is a different and more permanent thing. The resin turns up the wall in a continuous curve, so the floor and the wall become one surface that a mop can actually follow.
It also changes how a room cleans. With a square corner you are working a mop into an angle it does not fit; with a cove you run straight through and everything comes with it. That is why you find coving in commercial kitchens and clean rooms as standard, and there is no reason a house should not have the same thing where it helps. In your laundry, your pantry and under kitchen units it is worth every inch it takes. The cove is the same material as the floor: here is how the layers build up.
