I'm building a tiny home on a trailer. I want the walls to breathe but still be waterproof beneath the cedar siding. This product seals too strongly for that correct? What would you recommend? I might be driving in the rain at times so water intrusion will be higher than a standard build. SAMPLE - AFM SafeCoat, DynoSeal Concrete & Masonry Sealers

AFM Dynoseal is designed for below grade foundation walls, roofing, fence posts and raised garden beds. Two coats creates a waterproofing membrane that does not breathe. If you wish to seal the exterior sheathing beneath the cedar siding our AFM Watershield would be a suitable product that is breathable and designed to block moisture intrusion.
