Surface Preparation Guidelines
- Best results are obtained when Log Jam is applied to wood that has been previously coated with a compatible and thoroughly cured stain.
- Clean the log surfaces thoroughly to remove dirt, pollen, bird droppings and other surface contaminants.
- Check the log surface temperature. The surface temperature should be between 40˚F (4˚C) – 90˚F (32˚C). Log Jam is best-applied in moderate weather conditions, i.e., out of direct sunlight, and in dry, warm conditions.
- It is always best to use a bond breaker when prepping the log surface for Log Jam application. When chinking round logs we recommend using Grip Strip Backer Rod that has been securely stapled or nailed into place. When chinking flat logs with a milled in chinking line, use a quality masking tape centered in the milled groove. Using these techniques will provide a bond breaker that allows the chinking to stretch as the logs move.
- Apply Log Jam using a chink pump, a bulk loading gun, or a large caulking gun.
- The ideal Log Jam chinking thickness should be no less than 1/4 inch and no more than 1/2 inch.
- Mist Log Jam with a light water spray prior to finish tooling.
- Tool Log Jam with a wet foam paint brush to help ensure good contact between the chinking and the log surface. This will greatly aid adhesion of the chinking to the log.
- Keep a wet rag handy to clean up any spills or excess Log Jam.
- After Log Jam cures it is very difficult to remove spills and excess material.
