  1. Hi what is the proper way to waterproof a tile shower? every contractor i talk to has a different answer and me and the wife are lost to what is right and what is wrong. We have had a leak for ages and we are scared of spending all the money and not get the result we want.

    • Hi Lewis, thanks for the questions. Depending on where you live us being in Perth, Western Australia every country has a different waterproofing method as well as individual people. Australia waterproofing standards are not very high for different reasons. Really before 2000 it was the wild west of waterproofing with the standard being whatever works for you. The reality is we have a few key methods that are crucial. Preparing the area now that means removing anything that would affect the membrane including dust, priming the area to allow whatever waterproofing to hold is crucial you don’t want it coming away, application of at least two coats of the waterproofing at a high level that allows for where water will practically go in the shower the floor being the crucial spot, lastly dry allow it to dry and dry and dry if you don’t you will have a breach and be back to square one. Hopefully, those keep aspects of waterproofing help Lewis
