    skimmer crack repair

    I have a crack inside the skimmer wall. The previous owner repaired the crack, I can see white putty like material along the crack line. The skimmer is leaking now again. I searched the board and found out that I can repair the crack with 2-part epoxy. My question is that how do I figure out if the previous owner used 2-part epoxy. If so, do I need to get the old epoxy cleaned up before applying new epoxy? Can I just sand off a thin layer of the old epoxy. Does epoxy bond well with old epoxy? I will take pictures once I get home. Thanks.

    I would get the previous stuff off the crack with some fine sand paper to get it cleaned up the best you can. Then use the epoxy.

    JB weld might also work but I can't remember for sure if its ok for plastic. You could check and see if it is.

    took a picture of the crack. Looks like the crack was caused by concrete/soil movement. In this case, can I sand off the white putty and seal it with silicon sealer? How long will silicon sealer last under water?

    No one can tell you how long silicone will last but I can tell you for certain it is not as good as epoxy.

    You could try the silicone and, if it fails too soon, then use the epoxy.

    Polyurethane caulk will do a better job than silicone (but it's harder to work with) and neither one is as good as epoxy.

    The upper part flex a little, I can push it in with a finger a bit. In this case, can I still use 2-part epoxy to seal the crack?

    got rid of the previous putty and found the gap is fairly big, a little bigger than the thickness of skimmer wall. Can epoxy hand the wide gap like this?

    I found JB Weld at home depot, is JB Weld the same as 2-part epoxy? It works on fiberglass, PVC plastic and metal. How do I tell if my skimmer PVC is plastic?

    Re: skimmer crack repair

    I had to repair a crack in my skimmer. I used marine epoxy and a piece of flat plastic I got from Lowes. The plastic had to be cut and trimmed to fit with a dremel. The crack had to sanded a little to rough up the surface. Then I coated the plastic with the epoxy, placed it over the crack, and put three bricks on top to apply some pressure. All this was done under water and so far (1 year) it has held up and shows no sign of coming loose or leaking.

    Re: skimmer crack repair

    I can either get the JB WaterWeld or the original JB Weld that come with 2 tubes. I have pool drained to below skimmer now, so I can use either one. Which one is better?

    I am opening my above ground and I just noticed I have a leak in my skimmer. I must have cracked it when I pushed the hose on. I tried putting that vinyl pool patch on it and that didn't work. Now, I'm draining the pool to the crack and I'll let it dry and use epoxy.

    It is a better first try rather than replacing the skimmer.
