I have a 20x40 in ground pool with a tear in the corner of the vinyl liner in the deep end. I have placed a vinyl liner patch over the tear but now it has started to tear again. I need this corner to just hold out through the season/winter. I cannot afford to replace the liner till the spring. Would placing another patch over the current patch be helpful or am I just kidding myself? They seem to be starting out as dime sized tears and then just spreading. It spread past the patch this time. Would a larger patch be helpful or would it just tear behind it? Any suggestions would be very helpful. thanks.
