how much overlap with underlament

Actually this product comes with a built in "lip and tape" so you would be overlapping that film and using the built in tape strip to seal.
Was this Answer Helpful ?Joints are butted together at ends and sides,not overlapped. Seal with tape to hold in place. Overlapping may cause a slightly uneven floor.
