Shower Waterproofing

Hi, I am trying to tile my own shower using the Laticrete Hydro Ban system. I have never tiled before. Current plan: Wall material: Laticrete Hydro Ban Board with sealant at seams and sealant over screw holes Wall Flattening: Built with Foam Shims to plumb walls Wall tile: 24" x 12" light grey marble tiles Floor tile: White marble basket weave mosaic (1"x2" and 3/8"x"3/8) Curb: Laticrete Hydroban shower curbs (white foam like a cheap cooler). Pan: Dry packed pan using Laticrete 209, Mortar Lock Ledgers, and FloFX bonding flange I originally planned to use liquid Hydro Ban 1 (single application, troweled on) as the sole waterproofing for the mud pan (e.g. no corner fabric). Since I have never tiled before, I was drawn to liquid Hydro Ban 1 alone since it minimized build up and would make tiling tiny mosaic tiles easier. However, after reading more on this forum, I am concerned that it won't be durable enough. Q: Is liquid Hydro Ban 1 alone a bad idea? If so, how do you recommend I waterproof the dry pack mud floor? Q: Should I use the NoFlo membrane and preformed corners instead? I can't buy Hydro Ban membrane locally in small sheets. Q: Should I used the Laticrete Hydroban shower curb or use the GoBoard or Schluter curb instead? Q: Is it a good/bad idea to use the Built With Foam shims with Hydro Ban Board and marble tile? Thanks all!
