Can sheet vinyl flooring be PROPERLY installed without adhesive?
There are some “loose-lay” vinyl floors that are designed to be installed without adhesive. If your floor has a white foam or hard slippery backing it may one of these. When installing loose-lay, the tape you mentioned should be installed only in doorways, along seams, and underneath appliances. Also it should have a 1/4″ gap around the perimeter so that the contraction of your walls in the wintertime does not cause the floor to wrinkle. If the floor has a grey felt back it must be glued. And this means the entire surface. Vinyl can also be acceptably installed over old vinyl but the old must be prepped with cementatious floor patch to prevent the pattern of the old floor from showing. Definitely sounds like bad work.
