Unusual use of RainSlicker plus Typar: backwards?
I asked a question on this forum about some masonry details, and it suddenly occurred to me that I need a bit of advice on another aspect of my wall.
With a masonry/air-gap system, I am going with a 3d drainage mat in between two water-resistive barriers. The first is already on the sheathing, in the form of a liquid-applied membrane (StoGuard.) To complete the WRB system, I figured I’d use a product that integrates the drainage mat and a second WRB–HomeSlicker Plus Typar.
Trouble is, this requires installing the HomeSlicker BACKWARDS and UPSIDE DOWN, so that the Typar is on the outside. Is this absurd and can’t possibly work, or is it brilliant? Will the Typar flaps work adequately in shingle-lapped style to shed water down the surface? It’s meant to be butt-jointed at vertical joints and lapped with a separately-attached piece of Typar, so how would that work?
