Caulk & Stains

Sashco Caulk

The Sealant Made for Log Structures

No matter what it encounters, wind, rain, sleet, sun or snow, Log Jam chinking effectively holds its seal.
Whether you’ve just built the log home of your dreams, or purchased an existing log home, you need to know that your investment is protected from the elements. Nature is harsh as wind, humidity, insects, and UV rays all constantly attack the logs of your home.
Ordinary caulks crack and peel away from logs. Not Log Builder – it creates a lasting seal, preventing gaps and cracks.
