Triple Stretch Chinking

Weatherall Triple Stretch Surface Preparation
• The logs must be clean, structurally sound, dry (23% moisture content maximum) and free from any grease, paraffins, oils, petroleum distillates, urethanes or other surface contaminants that could inhibit the ability of the sealant to bond to the wood fibers.
• Any finish, whatever the composition, may be incompatible with the sealant system if the finish deposits a heavy film on the surface of the wood.
• The sealant must be able to bond to the wood fibers; therefore, use only a penetrating water-based finish prior to chinking such as Weatherall Log Guard Interior Clear Coat, UV Guard Exterior/Interior Wood Finish or UV Guard II Exterior Wood Finish.
• Please Note: If you are about to apply Triple Stretch Textured Log Home Chinking over a preservative or wood finish not provided by Weatherall Company, Inc., or if you are in doubt as to the compatibility of a previously applied preservative or wood finish, please contact Twin Creeks or Weatherall Technical Support prior to application of Triple Stretch Textured Log Home Chinking.

Weatherall Triple Stretch Chinking Application Information
• Recommended Thickness - Finish troweled thickness should be from 3/16” to 1/4” across the face of closed cell backer rod.
• Triple Stretch Textured Log Home Chinking should not be applied when temperatures are below 40° F., or when subfreezing temperatures are expected within 48 hours of application. Avoid chinking in the rain or when rain is imminent.
• Do not chink on a hot surface. When chinking in very hot weather, it is recommended that the chinking be applied to the shaded side of the house.
• Please Note: There may be occasions when chinking in subfreezing or rainy weather is unavoidable.
• Chinking can be applied with a bulk loading caulking gun, grout bag or commercial chink pump.
• Do not thin this product with water.
• Apply bead of Triple Stretch Chinking Log Home Sealant as needed to cover the joint. The applied bead should be firmly troweled into the joint edges to ensure complete edge adhesion. Use of a 50/50 mixture of isopropyl alcohol and water in a spray bottle will act as a release agent allowing the trowel to glide smoothly over the chinking.
• Do not spray release agent directly on the wood surface.

Please Note: UV Guard Exterior/Interior Wood Finish, UV Guard II Exterior Wood Finish or Log Guard Interior Clear Coat should be applied prior to chinking for three reasons:
1. They act as a primer and create a better bonding surface on which to chink.
2. Pigmented stains subsequently applied will discolor chinking.
3. Maintenance coats of Clear Log Guard, UV Guard or UV Guard II will not discolor the chinking. Triple Stretch Textured Log Home Chinking should not be applied for at least 48 hours after application of Log Guard Interior Clear Coat, UV Guard Exterior/Interior Wood Finish or UV Guard II Exterior Wood Finish.

Applying Triple Stretch With Backer Rod
• When applying chinking to new construction or to previously unchinked structures, it must be applied over a flat-faced, closed-cell, non-adhesive backing such as Better Backer backer rod. This type of backer rod system provides several critical advantages.
1. It creates the ideal slip joint design which allows only two points of adhesion: to the wood surface at the top and bottom of the joint.
2. The edges create a wider “footprint” at the top and bottom where the chinking is in contact with the wood.
3. It provides a flat, even surface over which to tool the chinking.
4. It is water resistant and highly insulating.

Please Note: In joints less than 3/4” wide, closed-cell, polyethylene round rod may be used. In this case, it is important that a minimum chinking thickness of 1/4” be maintained over the entire surface of the joint. The effect will necessarily be a convex shape over the round rod. DO NOT cut the round rod in half and place the cut side out to simulate Better Backer. The cut face will not release the chinking which may fail at the edges.

Weatherall Triple Stretch Drying Time
• Triple Stretch Textured Log Home Chinking will be skinned over on the surface in 20-30 minutes and will be surface dry in 8-10 hours under normal conditions. It will be fully cured in 7-10 days.
• Actual times will vary depending on temperature and relative humidity.
• Chinking should be protected from contact damage for 2-3 days after application.

Weatherall Triple Stretch Clean Up
• Clean any uncured Triple Stretch Textured Log Home Chinking immediately with soap and water.
• If the material is allowed to dry, it may need to be removed with a solvent.

Weatherall Triple Stretch Storage
• Triple Stretch Textured Log Home Chinking must be protected from freezing and stored in temperatures that do not exceed 90° F.
• Opened containers may be stored by floating a thin film of water (1/16”) on the surface of the material, covering it with plastic, and tightly relidding the container.
• Do not store in direct sunlight.
