Log Jam Chinking is an acrylic elastic chinking joint sealant. Log Jam Chinking will give your log home the traditional, historic look of mortar chinking. Log Jam Chinking stretches and compresses as logs shrink and swell, up to 100% of its original joint size. Log Jam Chinking has excellent memory. That means it can absorb movement over and over again without tearing, pulling away, or looking "Stretched Out." And, because the majority of the movement log homes experience occurs during the first few years, Log Jam Chinking is guaranteed to absorb log movement for 10 years. Log Jam Chinking tightly grips to all species of wood (including oily woods like cedar) and most stains. Log Jam has a 1 hour fire rating and is the only chinking product on the market that is UL approved. Log Jam Chinking is recommended for use with Backer Rod.
Application Temperature: 40°-90° F. Clean Up: Soap and Water.
