Log Jam - large tubes

Fundamental Chinking Application Guidelines

Proper substrate preparation and application are imperative for product longevity. Read this Information Sheet, LJC 002, before applying any product.

1. Best results are obtained when Log Jam is applied to clean, dry, stained wood. Make certain there is compatibility between your stain and Log Jam. Call Sashco for guidance if in doubt.
2. Check the weather forecast. Finishing products are best applied in moderate weather conditions, i.e., out of direct sunlight, dry conditions and warm.
3. Check the log surface temperature. The ideal application range is between 50-90°F.
4. Install a bond breaker before Log Jam is applied. Backer rod, Grip Strip, and bond-breaking tape perform this function well. If Log Jam is applied over white styrene bead-board, it is best to cover the bead-board with polyester tape (to prevent adhesion to the beadboard). We do not recommend the use of blue or pink extruded polystyrene board.
5. Gun the chinking over the backing material. Ideal sealant depth is 1/2 of the joint width, but no less than 1/4", nor more than 1/2".
6. Tool Log Jam to ensure good contact with the log surfaces, especially to the upper log; this will greatly aid adhesion.
7. All chinking products may occasionally "blister". To avoid blistering:
   • Do not apply in direct sunlight.
   • Protect from direct sunlight for 1-2 days after application with white plastic sheeting tacked over the fresh chinking.
   • For detailed information, read Sashco's Savvy Bulletin, "Preventing Blisters".
