We are having problems with water leakage on the south side of our log home. When there’s rain and wind, the water comes in every single hair line crack (and there are bazillions of hair line cracks). We’ve rechinked the inside and outside and run calk and chinking in every crack we can get to, but no avail. Is there any spray on product that can coat the entire side of the house, fill every crack, and still preserve the log look?
