our logs where delivered in may ’05 and the house did not get enclosed until jan.-feb ’06. the logs have been sitting thru out the winter getting rained on and everything. we have not treated, stained ,or sealed the logs yet due to money. we have cleaned the logs with tsp, bleach, and pine cleaner. how soon do we need get the logs treated, sealed and stained before the logs will runion? and is it ok to caulk the logs before doing any of that?
