Liquid applied water resistant barrier
I am looking for a solution for a water resistant barrier for the north and west sides of a small 120 sq. foot structure where the aforementioned sides have less air flow, sunlight and are more exposed to moisture from a nearby stream. The structure is already built to the point of being roofed in, and has plywood sheathing. The overhangs are significant, but moisture has already caused surface mold on the back north and west sides (on the plywood).
My instincts tell me that a better solution than housewrap would be a liquid-applied barrier to insure no moisture penetrates into the walls and cause internal mold issues.
My question is: Is there a product that would accomplish this and can it be purchased for only a few hundred square feet?
