Log Jam chinking keeps your home comfortable while keeping the weather where it belongs...outside. Log Jam chinking is the elastic sealant that handles joint movement up to 100%, even in joints up to 4" wide, while maintaining its original appearance. With superior adhesion and elasticity, Log Jam chinking is guaranteed not to crack, tear or peel away from logs. Plus, it's the only chinking to hold a UL one-hour fire rating: when applied in accordance with Fire Resistance Directory Design No. UL519

Log Jam chinking's six textured colors seal your home with the traditional look of mortar and are available in two convenient sizes (5 gallon pails and 30 oz. cartridges).
