If you have a round pool, you should have no problem as there will be little to no pulling force on the adhesive. If you have an Oval pool, the adhesive will likely pull away from the straighter sections of the pool where the sides go from concave to convex. Tried Gorilla tape but this couldn't hold the cove in place reliably. ANSWER: Get some two sided carpet tape. I purchased a 15 foot roll ( Roberts Double-Sided Carpet Seam Tape - Home Depot ) and this stuff is very very sticky on both sides. Held the cove in place perfectly. Apply a 5 - 6 inch length where needed to the exposed adhesive backing of the cove. Be careful as once applied, it wont come off without tearing the foam. Then peel the 2nd side and press onto to pool siding. Original Doughboy cove had both an adhesive backing and a plastic guide/support that fit into the bottom rail of the pool siding. That combination worked very well, but then the Doughboy cove is 2X+ more expensive.
