What a Floor Does While Nobody Is on It
Very little, and that is the point. It does not grow anything, it does not hold a smell, and it does not take on moisture from the air the way carpet and timber will over a long closed up summer. When you come back you are opening the door onto the same floor you left rather than one that quietly changed while you were gone. A vacuum, a damp mop, and your house is ready to live in again that afternoon.
The other thing an empty house does is get hot, and heat is where a lot of floor finishes give up. Vinyl planks lift at the seams, adhesives soften and timber moves. A polyaspartic topcoat is stable through all of that, so a closed up house in July is not a problem you have to plan around. You can shut the door in spring and open it in the fall without wondering what you will find, which for most people is the whole reason they were asking about the floor at all. Stability through a hot summer comes from the topcoat: here is what each layer is for.
