Basics of Chinking Application
1.The first step in good chink joint construction is to make sure that the surface is clean, dry and free of contaminates. Oil based stains and sealants, along with dirt, loose wood or bark can affect the bond of the chinking to your logs.
Application of bond breaker tape to a log wall. 2.Then when applying a synthetic chinking product like Log Jam it is important to obtain two point adhesion. This is achieved by first applying either a bond breaker tape such as shown in the photo at the left or by the use of backer rod as shown in the photo below right.
Backer rod or bond breaker tape should be used any time a joint exceeds 1/4" in width to achieve proper joint construction with two point adhesion.
The diagram below shows how to properly construct a chink joint, to allow for two point adhesion. Two point adhesion allows the chink joint to stretch without tearing. Tearing most often occurs when the joint is restrained across the entire surface of the joint. Applying backer rod to log corner stack.
A properly constructed chink joint with two point adhesion. 3.The next step in the process is the application of the chinking product, this can be achieved by use of a mechanical or pneumatic caulk gun, grout bag, a chink pump such as the Snorkler or a putty knife or spatula. Use the method that best suits your speed and ability.
4.After the application of the chinking material, some smoothing will be required. Again, selection of the tools used in smoothing the chink joint are up to the applicator. Some common tools include; trowels, putty knives, spatulas, spoons or foam brushes. Application of chinking with a caulk gun.
Do not apply more chinking than you can get tooled before it skins over, usually 15 to 30 minutes depending on the environment. Temperature and humidity greatly effect working time.
Smooth the joint using the tool of your choice. To extend working time many applicators will use a spray bottle of water to lightly wet the joint and aid in tooling to the desired finish. Some applicators insist on a perfectly smooth joint, while others prefer a rougher more rustic finish. Be careful when using water not to over do it, a light spritzing is all that is required.
Can you do your own chinking? That question, you must answer for yourself. The application of chinking is more of an art than a science.
Many factors must be considered, your ability, scale of the project, speed in which the project must be completed and other conditions determine if you should undertake the project yourself or leave it to a professional. Remember, as with most finish and sealing applications, proper joint construction and surface preparation are the key to the longevity of the project. A spray bottle and a light application of water will aid in extending workability of the chinking.
