Log Jam® Chinking

Log Jam® Chinking


Log Jam®, the standard for synthetic chinking.

Davy Crockett’s log cabin was cozy…except that it wasn’t. He spent a good amount of time plastering mortar into those chinking joints every year. Old-time mortar cracks and crumbles, allowing in wind, bugs, dust, rain and pollen. That’s why Sashco created Log Jam® Chinking, the standard in synthetic chinking. Its texture recreates that old-time mortar look while sealing your log home from vermin and wind alike. It stretches and won’t let go when your logs move. With Log Jam® chinking, you can keep the cozy feel and rustic look without compromise.
