has anyone tried adding a waterproofing agent such as Sylasec to papercrete?
somewhere i found out that if you add it to cement regular cement, it makes it waterproof?
otherwise that particular product seems designed to make a waterproof concrete paint
by mixing it with portland. i haven't had a chance to test it yet but wonder if anyone else has?
i am trying to get my head around the idea of where permeability is 'useful' and how to apply that-
as in traditional hogan roof ,which i understand, uses layers of different clays, using the varying
water absorption properties as an advantage...i am looking at a ferrocement shell with papercrete render
but whether it would be best on the inside or the outside is the question?
