MichaelReed Posted January 29, 2019 Report Share Posted January 29, 2019 I have a Tiger River Manora hot tub that has developed a fairly large, horizontal crack in the tub liner, between the light & the filter well, about halfway up the side. I'd sure appreciate any suggestions as to repairing it. I realize replacement is inevitable, I jus wanna buy some time. Quote Link to comment Share on other sites More sharing options...
Cusser Posted January 30, 2019 Report Share Posted January 30, 2019 I'd try marine epoxy, should be waterproof. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted January 30, 2019 Report Share Posted January 30, 2019 If the tub is acrylic/fiberglass, we've had success using Fiberglass repair resin, the same stuff you'd use on a car. It'll look like hell, but at least it will create a watertight seal. First, rough up the surface with sandpaper. I usually drill a 3/6" inch hole at each end of the crack - it's supposed to stop the crack from growing. Cut a fiberglass patch that will overlap the crack. If possible, but the patch on both the back and front of the tub shell. The front for water tightness, the back for strength. Mix the resin and hardener - you can add color but good luck on getting anything that will match. I use tongue depressors to push the resin into the patch and holes. Out of the can, it dries to an ugly, yellowish plastic sheen, but it will be watertight. Dave Quote Link to comment Share on other sites More sharing options...
