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. It’s obvious he…





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
