[Shop-talk] How join AZEK to sheetrock

[Brian Kemp]

USG's Durock system is gray - might blend in more.  I did two showers 
with their system and it was great.  Got it through a local flooring 
supplier.  Some Home Depots carry it too.

In John's case, since the plastic wall is already there and likely to 
expand/contract differently than the drywall, I'd just cover the gap 
with some trim of some sort - something like

or

If it is just a short seam, you could also get a self adhesive floor 
tile or luxury vinyl tile and cut a strip a few inches wide to cover the 
gap.
