For the patch you would use a Vinyl pool kit, you can get them at Home Depot, walmart, or a pool store easily.Well, I find myself having to do this mod to my pool this year. The original liner is bleached out completely, and the bottom has a rough texture to it (the pool was given to me by someone that used pool store shock granules, and didn't pre-mix them with water). This is more of a maintenance and ascetics thing (trying to prolong the need for a replacement pool and make the liner look better).
I think that I am going to cut the drains flush on the inside (preserving the reinforcements around them). I have an old intex pool liner from an old quickset pool that I am thinking of cutting a 12" square patch from to apply to the inside of this pool where the drains have been cut out of. I am hoping that this will be an improvement so my replacement liner doesn't even TRY to bulge through the hole from the old drain. If I understand it correctly, the intex liner is a type of PVC, so I was wondering if anyone would know if a regular PVC cleaner/cement combo (the same as is used with pipes) would work for this purpose, or should I use a different adhesive?
This is a 24' X 52" Metal frame pool that I bought an overlap liner for.
I am also thinking of trying to fold the liner back on itself, and tucking it back to the inside of the pool (trapping the overlap between the new liner, and the old), and running a soft 1/4" rope through the fold to give the tarp clamps something to grip to (since the clamps the OP showed are no longer being sold). What are your thoughts on this?
