Hydroban liquid membrane and screeting shower walls
I am a DIYer working on two new construction showers where the contractors did the framing of the shower and used Glasroc as the substrate. I plan on using hydroban liquid membrane as the primary waterproofing as well as their antifracture membrane in the corners/changes of plane then screeting the walls to get everything square and plumb.
I have some concerns about the layering of hyrdroban (antifracture fabric) > thin set(screeting layer) > hydroban (waterproofing the field) > thin set> tile. I assume its better to have fewer layers of different materials binding to one another. My question is whether I should hydroban the whole shower(for waterproofing the field) before screeting or after.
Lastly, thanks so much for the videos, information and forum to help DIYers get this work accomplished. I really appreciate how Isaac explains the nuance of tile setting and his values around helping people. Itβs obvious heβ¦





We have had to reframe. Remove drywall and reinstall in order to make our tile assembly look flawless. I know it's extra work. I would still consider removing that board or like you said adding enough to get a FULL tile at the knee wall. Drywall is a pretty easy fix, that tile assembly is forever. Do what you can to make it right
