Perma-Chink is a flexible and textured log home 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. Like all of Perma-Chink products, Perma-Chinking is easy to apply and comes backed by the support of our knowledgeable of our friendly staff. When you use Perma-Chink, helpful advice is never more than a phone call away. Application can be done by the homeowner or a professional contractor.

Areas to Use Perma-Chink:
• On the Interior and Exterior.
• On chink-style log homes and to replace old, crumbling mortar on older and historic log homes.
• To create a chinked look on a wood sided surfaces such as our log siding. 

Application Methods:
• Chink Pump.
• Bulk-loading gun and follow plate available here.
• Application bag.
• Single Caulking Tubes 

Measuring Your Chinking Project:
• The width and the cumulative length (linear feet) of the gaps or joints that you want to seal are the 2 measurements that you'll need.
• Width: If the chink joint is on a squared log, it is the distance between gap of the upper and lower log surfaces. With a round log chink joint, you first have to insert a length of proper size backer rod and measure the distance between the top and bottom logs about 3/8 of an inch in front of the surface of a backer material such as Grip Strip
• Figuring the Cumulative Length: Start by measuring the length of the wall. Then count the number of joints between all the log rows that you need to seal. When you multiply these two numbers together you have the total linear feet of sealant needed for that wall.
• The depth is an average depth across the joints.

Chinking Application Tools:
• Application bags, caulking gun or bulk loading caulking gun.
