why use them in a shower or all wet areas that is the worst advise i have ever heard im 40 and have been tiling from 18 man and boy some advice on here just doesn't fit im sure bal & mapie & ardex would like to hear their products are not water proof
so you have wasted 22 years of your life then deno? if in that time you havent learnt that grout is not waterproof..merely water resistant then you are the one giving bad advice to your customers my friend.
im sure mapei and bal and ardex are quite aware there products are not waterproof this is why all these companies make,supply and sell tanking kits:mad2:
