PERMA-CHINK - Log Home Sealant

Since 1981, Perma-Chink Log Home Sealant has proven itself on thousands of chinked and chinkless style homes to become the most widely applied chinking in the world. It's simply the best chinking by every measure: longevity, appearance, performance and ease of application.

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. 

Application can be done by the homeowner or a professional contractor. We stock a full line of application accessories or can refer a professional applicator in your area.
