I feel like I'm gonna need a few pallets worth of caulking to seal up my cabin. What brand have you all found matches the mortar best? I used premixed bags for my chinking.

I know they sell a mortar caulk for cracks in brick mortar etc, but that doesn't have any sand or texture to it, which I think would be nice to have on the inside at least.

Also something that would stick to the wood well and be flexible I think is important no?
