Perma-Chink Chinking 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 Chinking 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. Features & Benefits:• Eliminates Air and Water Infiltration• Remains Flexible to Allow for Log Movement• For Exterior and Interior• Suitable for all Climates Coverage Rate Chart: • Coverage Chart refers to linear feet per 5 gallon pail of Perma-Chink. • Perma-Chink should be applied 3/8" thick• 1 Pail = approximately (55) 11 oz. tubes• 1 Pail = approximately (20) 30 oz. tubes Color Chart: Where to Use Perma-Chink:• Interior and Exterior• On chink-style log homes• To replace old, crumbling mortar on older and historic log homes• To create a chinked look on a wood sided surface Application Methods:• Chink Pump• Bulk-loading gun and follow plate• Ratchet caulking gun• Application bag How to Measure My Chinking Project:• There are two dimensions that you need to know in order to determine how much product you will need: the width and the cumulative length (linear feet) of the gaps or joints that you want to seal.• Figuring the Width: If it is a chink joint on a squared log it is the average distance between upper and lower log surfaces. If it is round log chink joint you first have to insert a length of proper size Grip Strip and then measure the distance between the top and bottom logs about 3/8 of an inch in front of the surface of the Grip Strip • Figuring the Cumulative Length (Linear Feet): It is best if you break it down to one wall at a time then add all of the walls together it becomes much simpler. Start by measuring the length of the wall with a tape measure. Then count the number of joints you need to seal. Usually it is the number of log courses minus one. When you multiply these two numbers together you have the linear feet of sealant required for that wall.• Keep in mind that the depth is an average depth across the joint. We tend to think of the depth in the middle of the joint where it is actually the thinnest. If your estimations are generally short, check to see that you use average joint depth.
