Description:
Log Jam is the only chinking material that is guaranteed not to crack, tear or peel away from your logs. It keeps the inside of your home comfortable while the wind, rain, snow and bugs are kept outside. Log Jam will maintain its' original appearance even after joint movement up to 100%.  Since its introduction in 1985, Log Jam chinking has been the recognized industry standard in elasticity, adhesion and durability, and Log Jam is still the only chinking to hold a UL fire resistance rating.   When other chinking products pull away from logs, leaving your home vulnerable to weather, air infiltration and insects, Log Jam is still maintaining a tight seal.

Chinking Installation Tips:

1. Start with dry logs. Their moisture content should be below 20%.
2. Apply log stains before installing the chinking material.
3. Clean your logs prior to applying any chinking material. Any loose debris, dirt, dust or grease could adversely affect the adhesion of your chinking.
4. Install backer rod before applying any chinking products. Backer rod is available in closed cell and open cell forms.
5. Select a chinking material that is going to be compatible with your log home stain. If you are unsure about the compatibility of your log chinking and your log home stain then speak with the manufacturers of both products.
6. Do not apply chinking in direct sunlight. This could lead to blisters in the material.
7. Apply 2 to 3 feet of material at a time and then work the material with a foam brush or trowel.
8. Use a spray bottle to mist the chinking if it dries too quickly.
9. Clean as you go. Soap and water can be used if the material has not dried.
10. Chinking should be installed to a depth of 1/4”.
11. Avoid chinking in the rain or when rain is imminent.
12. Chinking should not be applied when temperatures are below 40° or when subfreezing temperatures are expected within 48 hours of application.

What is the difference between chinking and caulking materials?

Chinking is an elastic sealing material that has a coarse surface which is designed to look like old-fashioned mortar and is typically used on larger joints. Caulking is a highly elastic sealing material that has no surface texture and is mainly used in smaller joints.

Color
Mortar White, White White, Buff, Tan, Gray, Woodtone Cedar

Packaging
5-gallon straight-sided white pails and 29 oz. fiber cartridges

Water Resistance
Log Jam forms a water-resistant skin in 1-4 hours after application. This resistance depends on bead size, humidity and temperature. If applied in cool or humid weather and rain is imminent, covering the chinking with a plastic sheet may be necessary.

Service Range
-30°F to 250°F

Paintability
Paintable with oil or latex stains after 1 week cure time. If giving chinking a facelift with Brush Over, make sure chinking is cured.

Compatibility
Compatible with most sealers and preservatives, including linseed oil, borates, pentachlorophenol and copper compounds. NOTE: Some coatings contain wax or other chemicals, making adhesion difficult. Call Sashco for more information.

Shelf Life
18 months from date of packaging.

Discoloration - Passes ASTM C834-00

Snow
Be cautious of areas where snow builds up around the structure and remains for extended periods of time. Snow removal is recommended for these areas to ensure the ultimate adhesion of Log Jam.

¹ Ultimate adhesive strength attained in 3-6 weeks depending on bead size, temperature and humidity.
² Dry adhesion is tested after 28 days room temperature cure. The average of several tests is reported.
