Use Log Jam® Chinking inside and out:

• On chink-style log homes
• To replace old, crumbling mortar on older and historic log homes
• To create a chinked look on a wood sided surface
• • Rustic look without the rustic application: The textured formula is easy to apply, even for a novice, for a Daniel Boone-approved mortar look. 
• • Keeps the weather where it belongs - outside: Moves with your logs to create a permanently waterproof and weatherproof seal. 
• • Helps you avoid repeated repairs: Just say no to crumbly mortar or cracked chinking. Stays soft and elastic over time for a long-lasting seal. 
• • Easy to clean up: Easy to smooth and clean-up with water. 
• • No special chemicals required
