No problem with this product. No defects. Just a simple roll of foam. I suggest you buy less expensive spray adhesive at home depot. I sprayed only the top 6-834; inches and the full seam. Save bucks and don't spray the whole wall, as you don't need to. 6-834; from the top will securely hang your foam till you get your pool filled.
