Chinking a log home requires patience and an artistic touch. It is typically done by professional chinking contractors but can be accomplished by homeowners. Follow the guidelines below for a successful job.

1. Start with clean, dry and sound wood. The moisture content of your wood should be below 20% and rain should not be in the forecast for at least 7 days prior to your start date.

2. Check with the chinking and stain manufacturers to ensure that your finishing products are compatible with each other. It is always a good idea to use a stain and chinking from the same manufacturer in order to avoid any unnecessary problems down the road.

3. Install some form of backing material before applying the chinking material. This will allow the chinking material to expand and contract like a rubber band. Also, it will save you money in chinking material costs.

4. If the width of your chinking joint is greater than 1” it is recommended to use a bulk loading gun. If the width of your chinking joint is smaller than 1” it is recommended to use quart size tubes.

5. Do not apply chinking material in direct sunlight. For more information regarding this problem see our “Chinking Blisters” article.

6. Chinking material should be applied between 40-90 degrees.

7. Start by gunning out a 3′ section of chinking material.

8. Work the chinking material into place with a putty knife, trowel or foam brush. Do not gun out too much chinking material because it will skin over rather quickly and become difficult to tool.

9. If the chinking material does skin over, lightly mist it with water. This will help in spreading the material.

10. Make sure to get good adhesion to the top and bottom of the chinking joint. This can be accomplished by using the right amount of pressure with your tooling instrument.

11. Make sure to get the correct depth of material when applying the chinking. A good rule of thumb is a 1/2”.

12. Have fun with your chinking project. The more chinking material that you apply the better you will become at chinking.

Chinking material has been around for centuries. It has seen many changes over time. Typically chinking material is designed to keep the elements outside of a log structure. Also, it can be used solely for aesthetic purposes.

Who makes chinking? Well, there are 3 main chinking manufacturers that supply the majority of the chinking for the current log home industry. These companies are Sashco, Weatherall and Permachink.

Sashco is located in Brighton, Colorado. Sashco has been in business for over 75 years. Permachink is located in Redmond, Washington while Weatherall is located in Charlestown, Indiana. It is unclear and widely disputed who first introduced synthetic chinking to the log home industry. At this point it doesn’t really matter. What does matter is finding the right company that is going to stand behind their chinking material. Additionally, all three companies manufacture log home stains. I mention this because your log home stain and chinking must be compatible to avoid any adhesion problems. Typically, if a company manufacturers both chinking and caulking then it is a pretty safe bet that their products are going to be compatible with each other. Check with each product manufacturer before applying either material.

Chinking for log homes can be purchased in 5 gallon buckets of quart size tubes. Chinking colors range from white white, mortar white, buff, tan, woodtone cedar, gray, light gray, khaki and pecan. Chinking material is typically purchased by contractors but is available for sale to homeowners. We recommend using Log Jam chinking for the following reasons.

• It is the only chinking that has a 1 hour UL fire rating.
• It is the only chinking material that is freeze thaw stable.
• It is the only chinking material that offers a lifetime warranty.
• It is highly elastic and outperforms almost any other product on the market.
• It is the choice of most chinking contractors.
• It is available in 7 standard colors and any custom color can be created.
