How to seal bottom edge of rim joist?
Marine Zone 4. I’m in process of sealing and insulating my rim joists. The process is straightforward but I cannot for the life of me seal the bottom edge of the rim joist. I just can’t get my caulk gun in there because the back end of it hits the ceiling (subfloor) and the tip doesn’t get to the bottom corner. I tried an extension tube but all that accomplished was making a big mess.
Should I just forget about it and rely on the rigid foam and canned foam combo for air sealing?
