How to water seal a shower
There are many ways to seal a shower, but it pays to know which ones will stand the test of time.
Common sealants include products like silicone, which can be found in any hardware shop. Silicone is handy for a quick, cheap repair to a spot problem or re-caulking, but it will eventually peel and inevitably you will get water leaking behind the area, and mould. This can cause major issues later on, such as rotting floors, damp walls and even create nice damp conditions for termites in the frame of your house. The other problem with spot sealants such as silicone is that you might miss smaller leaks that you can’t see, but nevertheless could compromise your home.
There are more advanced sealants that can seal your entire shower recess. The huge benefit for these types of sealants is that you can be sure you have sealed even the smallest of cracks in grout and tiles, even if you can’t see them. Sealants such as Megasealed also come with a 25-year product warranty, so it’s a better long-term solution.
DIYing your shower sealing can save you some dollars up front, but you might want to consider getting in a professional. They can assess whether you have any further problems before sealing the bathroom, such as fixing grout or tiles if needed, and making sure there is no damage to the structure of your home from existing water leaks. They can also do the job quickly. Megasealed is usually applied within 3-4 hours and your bathroom is ready to use the next day.
