Our cabin was built in 1968 in NC from rough hand hewn logs out of SW VA est to be 125 to 150 yrs old. I’ve had exposed logs cobb blasted and since I have sprayed with a borate and sealed. I spent 5 days caulking every joint between log and chink. What is the best product to seal the joint between the logs and chinking with a sandstone chimney. It is caulked as far you can see, but I really want to confirm the connection is waterproof. Thanks for any advice! dp
