Log Builder Sealant Caulk


Freeze and thaw stable; okay to leave in your truck overnight.



Log Builder is a smooth, flexible and elastic sealant for milled and hand-crafted log structures that absorbs most log movement by creating a tight seal to keep water, bugs and wind from seeping into your home. Since it stretches up to 500% of original size, it won’t crack, peel or pull away from properly prepared logs. Water based for easy application and clean-up.
