Hot Tub Buying Guide
Repair your cracked hot tub
You have noticed a small crack in the acryclic of your hot tub. Or maybe you have a leak that you have traced back to a small crack. You will want to repair the crack before it becomes a larger crack and a larger problem. Be sure to check your warranty. A quick call to the local spa dealer may fix it with a nice visit from their tech who will repair it for you. If you are no longer under warranty, you can still make a call and have someone come repair it for you or you can fix it yourself.
Check underneath the tub beneath where the crack is and determine if the crack is through and through. If the tub is lined with fiberglass you can purchase a fiberglass patch kit to fix that damage, if indeed the fiberglass is damaged. Follow the directions closely on that patch kit.
To repair the crack in the shell, drain your tub. Clean and dry the crack and the surrounding area well. Shell repair kits are available for purchase and this is a great way to go. You can find them at your local spa dealer or online. Clear silicone (not caulk) can be put into the crack. This will degrade and discolor over time due to the chemicals in your tub and the heat, but it will keep the crack from growing and leaking for a while - keep an eye on it and replace when needed. Another option is fiberglass resin or acrylic repair products. Follow the instructions carefully and be sure to let it cure completely before adding water back into the tub. Your crack repair may be more extensive than this and may require you to seek more in depth information.
