Log Builder Caulk


The Sealant Made for Log Structures

Log Builder is specifically designed for the continuous motion inherent in log structures. With the ability to stretch up to 500% of its original size while maintaining strong adhesion to the wood, Log Builder is the ideal sealant for log homes.

Given that most logs experience movement during the initial years after construction due to moisture loss and shrinkage, it’s imperative to begin caulking your log home with the appropriate product. Log Builder adapts to the movement of logs, remaining elastic and ensuring long-lasting protection against the elements and insects for your log home.
