The Sealant Made for Log Structures

Logs are in constant dynamic motion. That’s why there’s Log Builder, the sealant made for log structures. Stretches up to 500% of the original size, while still maintaining tenacious adhesion to the wood.

Since most logs move within the first few years after building due to moisture loss and shrinkage, it is crucial to start out caulking your log home using the right product. Log Builder stretches and compresses as logs move and stays elastic, ensuring that the elements and insects stay out of your log home for years to come.
