Softub Liner Sealer?

[arcticman]

I live in the Northwest Arctic, Alaska and shipping is very expensive. I bought a used Softub from someone moving away, but found it has numerous cracks in the wrinkled plastic floor, so it leaks quite a bit. Otherwise, the rest of the liner and pump work well. Anyone ever tried some kind of spry on coating to seal this/ I was looking at spray on duct tape and PLasti Dip spray as possible options. A new liner is about $450 and then expensive to ship.

Any thoughts or experience?

After $450 plus shipping, you then have to install the liner. Installing these liners takes great care and precision. One false move and your $450 liner is junk. On the other hand, I have not seen any product yet that will seal a wrinkled up and cracked liner. One or two small leaks can frequently be patched, but not a lot of wrinkle cracks.

What about the rubber pond liner that they use for garden ponds? Maybe that would work?

Shower pan liner from the big box store and Noblesealant 150 (tile supply house) may do the trick for at least a season. If you got kids or have risk of a patch being pulled up, use noblesealant to bond the membrane across the cracking surface and 1" or so into the perim, and silicone to edge bond the perim of the patch to try to keep the edges from lifting (good luck though). Or go pond liner across the whole bottom and nobleseal the perim/silicone the perim where the walls turn up. Whole lot cheaper than a new liner, but it won't last forever. But $15 for sealant and a piece of liner isn't a lot of $$ to blow on the experiment.

We've used 150 on several shower pan installs bonding pvc and cpe sheet material and it's pretty amazing stuff. Consistency of thin taffy, sets up like chewing gum. But it doesn't have a lot of strength against peeling / delam (remember it's to be used under heavy mortar beds). Thus the hybrid- 150 for waterproofing, silicone to edge bond and try to control delamination.

Hi, I was curious if you were able to fix the leaks from the bottom of the softub liner? And if so, what did you try? I'm in a similar situation, but it was weeds that pushed through the liner in several spots. I pretty much need to seal the whole bottom floor. Thank you.
