I am going to build a Square timber(5” x 8”) sauna with flat on flat joints. What would you recommend for sealing between the logs? Would have to withstand 250 degree’s F and water. would you use a EMSeal or caulk or both?
They make a stacker caulk, but not sure if it will hold up to the temp. I would not put any sort of caulk on the interior. Call Dave at 800-564-2987 for help.
