I have recently noticed water puddling outside my above ground pool. I investigated inside the pool near this area and see a small L shaped cut in my liner and the patch I applied to a similar cut about 4 years ago is starting to come undone. I removed the old patch and have tried unsuccessfully to apply a vinyl patch with a basic pool patch kit by hth. I tried a few different patches but none of them adhered. The liner is wrinkling in many spots throughout the pool and is particularly wrinkled in the area of these 2 cuts. I can't flatten the liner and apply the patch at the same time. Does anyone have any other solutions or am I looking at having to replace my liner?
