Waterproofing both under and over screeds
There was a time when we used to just waterproof under a screed, tiled on top of those screeds and then found that the screed would get all wet, and even though the substrata would be protected, we'd have a mushy screed and that was retaining moisture in there, which is not a good thing, and that causes things like efflorescence very often on external balconies.

And somehow it found its way into waterproofing applications as a substrate for tiling and membranes in wet areas.

This one is very, very dear to me and I talk about it a lot when I do talks to applicators, and in trainings, and our staff continue to do this, and it's in all our data sheets, yet it amazes me how many times we still see issues out in the marketplace, where applicators get it wrong, and I'm not sure why that is.
