Perma-Chink Medium Gray - (1) 30 oz. tube
Price: $ 39.95
Perma-Chink is a flexible, textured chinking that seals the open gaps between logs to eliminate heat loss and air infiltration. Even though it looks and feels like traditional mortar, it's not. Perma-Chink is a pure acrylic that adheres to logs and stretches to maintain a tight seal by following log movement.
