Perma-Chink chinking

Perma-Chink chinking looks like traditional mortar yet adheres tightly to logs, maintaining a flexible, impenetrable seal as logs shrink and move.




Perma-Chink chinking

PermaChink chinking is a flexible, textured chinking that seals the open gaps between logs to eliminate heat loss and air infiltration.

Even though PermaChink chinking looks and feels like traditional mortar, it’s not, it’s a pure acrylic that adheres to logs and stretches to maintain a tight seal by following seasonal log movement.

Features and Statistics

  • Eliminates air and water infiltration
  • For interior and exterior walls
  • Stays flexible to follow movement of logs
  • Suitable for all climates
  • Application Temperature 40  to 90 degrees

Application and Preparation

Note: Although PermaChink skins over in 1-2 hours, it may take 2-8 weeks for a full cure, thus don’t go poking it with your thumb to see if it’s set up…best to put some on a test item that folks can play around with

As with all chinking products, it’s best to apply PermaChink chink toward the middle of the recommended temperatures, e.g. Low temps, high humidity can take a looong time to set up and cure, whereas high temps, low humidity may set up (skin over) so quickly that it can be difficult for a first timer to get it properly troweled out.

Finally: Apply out of the rain and direct sun.
