I recently inherited a log cabin. Someone in the past used something (maybe regular caulk) as chinking on interior walls. It is tacky in some places and just falling out in others. I have been pulling it out with a screwdriver but in most places it is tacky enough to still stick in the wood grain itself. I am thinking I will need to sand this off before replacing it with appropriate chinking. Most of the logs are so close together there is not really any space between logs and the "chewing gum" they were using is just sitting on the surface but still sticking to the grain. They used the same material in the checks. In some places I can pull it out but in others the space is too small to reach into. I am concerned that if I don't get a clean surface the appropriate material won't stick. Any thoughts or suggestions? Am I on the right track? Thank you!
