[papercreters] Re: papercrete on Faswall blocks

Thanks, Ernie.

I am not sure about the practicality of using papercrete on the
exterior as the house is in coastal Washington so lots of moisture.
What is the consensus on using papercrete in such areas and how best
to waterproof it while still letting it breathe. What would be the
best recipe for the exterior in such a location?
