Is it feasible/recommended to remove about ten worn out 15.5 inch vinyl tiles and replace them with 10 year old unused spares from the original installation? Tiles are grouted and color match is good.
If that is not the way to go, can I lay and glue new vinyl tiles on the entire floor, on top of the aesthetically worn but otherwise serviceable tiles? I assume the underlayment is good. I would avoid lining up the seams.
