Log Builder® Sealant

Log Builder® Sealant


Log Builder sealant is specifically formulated to absorb most log movement.

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.
