    Perhaps it's our basement floor, but on concrete this wouldn't stick and made a crunchy sound underneath the planks. We used one roll and decided to forgo for the rest of the room.

    Perfect for what it’s used for.

    Just as described, went down easily.

    We have a crawl space rather than a full basement so the barrier is necessary to prevent any issues caused by moisture which could rise from the crawl space.
