Rated 5 out of 5 by from Piece of cake This underlay made laying a boen oiled oak floor a breeze. It's a bit more expensive but it's a great quality product and actually per meter a very good price. Do not hesitate. Only reason not to give reliability a 5 star is we only laid at the weekend! So to early to really say
