Log Jam Chinking

Flexible Synthetic Chinking for Long-Lasting Log Home Sealing

Log Jam Chinking by Sashco is a high-performance synthetic chinking designed to form a durable, flexible seal between log courses. Engineered to maintain a strong bond while allowing for natural log movement, Sashco Log Jam helps keep log homes sealed, insulated, and protected for years.

Textured to resemble traditional mortar found in historic log cabins, Log Jam delivers a rustic appearance without the cracking, drying, or crumbling associated with rigid materials.

How Log Jam Chinking Performs

Log Jam Chinking remains soft and pliable in all weather conditions, stretching up to 250% of its joint size. This elasticity allows it to move as logs expand, contract, and settle over time, helping prevent gaps, air leaks, and moisture intrusion.

Unlike older mortar-style products, Log Jam maintains flexibility season after season while preserving a classic log cabin look.

Application Guidelines

Weather Conditions
Apply during warm, dry conditions when log surface temperatures are between 40°F and 90°F. Avoid direct sunlight during application.
Sun Protection After Application
To prevent blistering, protect fresh chinking from direct sunlight using white plastic sheeting for one to two days after application.
Backer Rod Installation
Install backer rod between log joints before applying chinking. The depth of the chinking should be approximately half the width of the joint, with a minimum depth of ¼ inch and a maximum of ½ inch.
Surface Preparation
Log surfaces should be clean, dry, and free of dust to ensure proper adhesion.
