Log Jam Chinking - Water-Based Log Home Sealant

Since its introduction in 1985, Log Jam chinking has been the recognized industry standard in elasticity, adhesion and durability. Also, Log Jam is still the only chinking to hold a UL fire-resistance rating. Log Jam stretches and compresses as logs shrink and swell—up to 100% of the original joint size (+/- 50%). Yet it maintains the traditional look of mortar, without “stretching out,” so it still looks good after years of log movement. Better yet, Log Jam sticks! When other chinking products pull away from logs, leaving your home vulnerable to weather, air infiltration and insects.
