Installing a pre-slope for a shower pan. If you have a tile shower and it never seems to dry out and always has mildew, it's because this wasn't done before the shower pan was installed. Without doing this first, the shower pan is basically just a big holding pond. For the bedding mud I use (1) bag quikcrete sand topping mix along with (1/2) bag quikcrete all purpose sand mixed in. Makes it easy to work with. Have to trowel out a layer of thinset on the floor first to give your mud something to stick to.
