I installed a no-wax floor 25 years ago in a small restroom with only a commode and is 3X6 in size. This floor is worn out but remains in tact and is solidly adhered to the floor. I am considering just installing a new no-wax floor over the old. This is a very small area with not more than 2 steps in either direction. Does anyone have any advice on if this will work and what needs to be done to prep the old floor. I plan to glue the new floor to the face of the old.
