Durock for siding?

john e k

Has anyone any experience using durock for exterior siding, with an elastomeric stucco top coat

Instead of a brown coat?
Sounds kinda crazy to me.
Maybe you could tile the outside?
That would look rad.
What do you have now, osb?
I really doubt if it could handle the elements.
But let's wait for someone in the underlayment section to respond because I'm not sure about such things.

durock isnt what you want for your base. standard practice around here is a layer of denshield over the studs then 2" of foam.. from there the finish coat know as dryvit or elastomeric stucco..... however if you live in a freeze thaw environment you may want to rethink using such a product.. its doesnt hold up at all.. there are many commercial buildings that gt that treatment but within 3 or 4 years the finish is failing

Durorock will work on the outside, but I am with Kirk on how to do this.

the difference between denshield and durock is that the denseshield is water proof. where the durock is just mold proof and not water proof
