Fiberglass repair
« on: October 12, 2018, 03:04:22 PM »
Hey -- I'm clueless here.  I don't really want to repair -- I want to cover the drain in the bottom of the hot tub.  It's got more of a drip leak than I want and we don't use the drain anyway.

So what shall I do to seal it up/cover it so it's sorta smooth enough for our tender feet?  I can't get underneath the tub - need to do it from the top. :? :?

Slim,

A quick search on ebay under plexiglass, ABS or Delrin sheets turned up some promising results. 1/8" plexiglass in a 10" circle for about 5 bucks. Get some silicone RTV and glue it to the tub over the drain. Quick and easy and no splinters...

Beat me to it Woody! SSS, if you got the tape version you could call it NASCAR "Bear Bond".

How about 4000 urethane (i think it is 3M).  I used to use that (or 5000) on various Sailboat projects  including a polyethylene water tank that fractured in some rough seas.  Fixed an 80 gallon tank with 4000 and it never failed even when green water was rolling over the cabin top and I was snapped onto my safety lines trying to figure out how I can make really dumb decisions!

If I remember right, the guys at West Marine told me "4000 for most underwater projects, or 5000 if you really hate the next guy that has to try to get it apart".  The cure time is truly as long as it says on the tube, but it wont eventually let go like the silicone sealers do.
