1 You can simply lay your vinyl floor on top of the subfloor. Just unroll, cut the floor to size and itâs done â easy!  Medium room ( < 25m2) Semi-loose installation will do. Use double faced duct tape around the room to secure the flooring.
Option #1: Tile Directly Onto Vinyl. 1  Check that the subfloor and underlayment total at least 1 1/4.

Apply tile to the vinyl with thinset.
