In the 1970s, log home owners everywhere were discovering that logs are in constant dynamic motion. They came to Sashco for help, and a few years later, Log Builder® sealant was born. It’s the sealant specifically formulated to absorb most log movement. For over 20 years, Log Builder® has been the trusted sealant included in many manufacturer’s log home kits and packages. Its superior elasticity creates a tight seal that keeps out water, dust, bugs, and wind.
