Chinking joint depth should be 1/4'-1/2'. The depth of chinking joints less than 1' wide should be half the width but no less than 1/4'. For chink joints 1' or more, the depth of the joint should be 3/8' to 1/2'. Mortar is fire resistant! A very important consideration. Chinking joint width of your logs should be between 1/4' and 2' and four times the anticipated movement. On a conservative estimate, chinking lasts about 40-50 years. Today’s synthetic or “elastomeric” chinking materials are more flexible – so as logs shift and settle, they are far less likely to tear or come loose. Of the two most common ones which is the best, mortar or synthetic chinking? This internal movement means the chinking is stressed and it must be able to flex and not break or split apart. Log home chinking, repair of log cabins, log staining, media blasting, rotten log repair. Log walls expand and contract with heat, cold and varying moisture conditions. In addition, the logs must be free of any factory applied oil-based mildewcides, non-penetrating surface finishes, and oil-based finishes. The logs must be at a moderate temperature, between forty and eighty degrees Fahrenheit, to avoid excessive evaporation. It must be sufficiently elastic to handle the normal expansion and contraction that wood experiences over time. There are four basic methods for applying chinking to log cabins.

More specifically, chinking can boost the R-value of log joints to almost the R-value at the log’s center. Any droppings on the logs may be wiped off with water and an old rag. Chinking is the sealing material that fills the gaps between the logs in a log home.Ĭhinking drastically improves a log home’s energy efficiency by reducing heat loss where the logs meet.
