My 1000 sq. ft. log home is about 8yrs old and sits on concrete slab. I have found drafts between the bottom log and concrete. I originally used silicone chaulk a few months ago but with the cold winter there was movement of logs causing 1/4” air drafts in a few areas. I know I must scrape out the silicone and chaulk or chink but which one? Will one adhere better between wood and concrete? Is there anything that improves conrete adhesion other than clean and dust free? I am a new log home
Chink is used when the gap or chink line is 3/4” or greater. Caulk is used for smaller lines. I would recommend the chink and get a good size line run. Unfortunately, silicone leaves a residue that can sometimes cause the chink to not adhere properly. You will want to make sure that you clean it off completely before applying the chink. Silicone should never be used on wood. It will not chemically bond.
