[papercreters] Re: exterior color , latex paint and moisture????

I think there is a big problem with using any kind of sealing an the
outside, at least in wet climate. Normaly the outside has to be 5
times as open for transfer of moister as the inside, to make sure you
are not embedding water. The only right solution must be a layer that
drains must of the water away. This could be ceder shingles or similar
material. Betwin this "skin" and the papercrete there should be a
ventilated space on around 25 mm (one inch).
