This collapsed ceramic can occur in any type of hot bathtub. Usually, this happens when the application of cement and sand dough is not good. To fix this, remove the ceramic and add a new cement mixture to make the ceramic surface parallel to the other ceramics. Fill the grout using white cement and glue. Meanwhile, if you want to avoid the bothersome repair process entirely, we suggest you only buy the most durable hot tubs.
If you have coated the hot tub with a waterproof liquid, wait for 3 to 4 days for the patch to dry. After the stucco is completely 100% dry and hardened, coat the entire hot bathtub interior with a waterproof coating. For the bottom edge and corner of the hot tub or large enough cavities, use fiber fibers. Wait again for 2 days until it dries, then repeat the coating once more.
The thing that should not be missed after patching a leaky hot bathtub is tidying it up. Prepare the cutter or tool used for smoothing the cement or glue. Usually, after the process of patching up a leaky hot bathtub, there will be several protrusions which can be an eyesore. Cut out some of those protruding parts and flatten each section so that the patched hot tub doesn’t look any messier and tidier. Because a tidy bathroom is key to building a comfortable bathroom.
After the patch in the bath is dry, check if there are still any leaks or the patching process is not yet complete. If the process of patching a leaking hot bathtub is still not perfect, for example, such as plaster that is not 100% dry, there must be a leak in the corner that we are patching in the form of water seepage. Seepage of stagnant water is very dangerous, so when designing a bathroom, it is recommended to use anti-slip bathroom tiles. It’s a good idea to make a drain hole at the bottom so that draining the hot tub becomes much easier. Avoid using a hard brush when cleaning the bathroom to prevent leaks.
