I live in a rural area without attic and only some walls with R13 insulation.
I am considering NSF certified elastomeric paint to cover shingles for the purpose of collecting rainwater for potable uses. It serves to cover toxic shingles, acts as a cool roof as well as a vapor barrier.
I am also planning on 2-3 coats of latex paint for the interior walls and ceilings of the kitchen and bathroom. This should also act as a vapor barrier.
I'm wondering if any building science folks might comment on the potential for mold potential between 2 vapor barriers.
