Some of you commercial guys have probably used this stuff. I am watching it being installed as a brick/splitface block substrate on a local hotel project, and wondering what that “yellow stuff” was. Close look revealed it was a gypsum-based product.
So, GP says that this stuff has a 6-month exposure warranty and a limited-lifetime warranty for whatever else. Question is, is this something that I can attach to the foundation of my house (over ICF’s, above grade) and stucco it or attach cultured stone? If so, I’d rather use it than Durock, which is a pain in the arse to cut and install. I posted about using Hardibacker a couple months ago in the same application, decided against it, but this is something that seems especially suited for my application.

Hi Jon
We have used Densglass alot in the tropics. It holds up well as long as it never gets soaked. I wouldn't use it near grade. It works like sheetrock but the fibres in it will itch you like insulation does. It is way easier to deal with than durock but probably not as durable.
Why are you not just coating the ICF's with Accrocrete or other elastomeric plaster products?

I want something that is durable, can withstand minor impacts, and can be used as a substrate for a future stone veneer. I really don't know what's available. If I can't find a better option, I'm going to attach pieces of Durock to the ICF's and stucco/plaster over them.
