How to Apply Log Home Chinking Material

Published on | Log Home Chinking |Leroy Walker

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.

  • Ensure that your wood is clean and dry before starting your chinking job. The moisture content of your wood should be below 20%. Rain should not be in the forecast for at least 7 days. Also, make sure that your stain and chinking are compatible.
  • 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 and save you money in chinking material costs.
  • Use a bulk loading gun for chinking joints that are an average of 1'' or greater and quart size tubes for smaller joints.
  • The chinking material should be applied between 40-90 degrees. Do not apply the chinking material in direct sunlight. This could lead to blisters in the chinking material which are not fun to repair.
  • Start by gunning a 3' section of chinking material onto the wood substrate, smooth it out with a putty knife, trowel or foam brush. Do not gun to much chinking material to start with because it will skin over rather quickly and become difficult to tool.
  • If the chinking material does skin over, lightly mist it with water. This will help in spreading the material.
  • 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.
  • Make sure to get the correct depth of material when applying the chinking. A good rule of thumb is a 1/2''.
  • Use a foam brush or rag to clean up the chinking material as you are applying it. It will become a major project to wait and clean it up at the end of the day.
  • Have fun with your chinking project. The more chinking material that you apply the better you will become at chinking.
