So you guys are saying not to get the self sticking, underlay or tape?
All I used was flooring that already had an underlay on the underside of each piece. No tape, nothing else. I wouldn’t go with the kind that sticks, as others have stated. I know they do make waterproof laminate flooring, but I don’t know if that stuff needs tape or a sealant in between the pieces. Ask the Lowe’s or HD employees about that if you go look there.
