There are two types of sealants used in construction and maintenance of log homes or log siding. They are:
External Sealants - Perma-Chink, (matches the look and appearance of traditional mortar chinking) and Energy Seal (which blends in to hide wall joinery). External sealants are installed after stacking logs and are visible when construction is finished.
Internal Sealants - Stack-n-Seal (specialty sealant used between mating surfaces of stacked logs) and Gasket Tape. Internal sealants are installed during the log stacking process and are hidden when construction is finished.
