I have a log home in Vt which was built in the 70’s. It appears that it was never stained but natural. It has a lot of dark brown to black weathering. I would like to preserve it. Should I power wash it? Blast it or can I just wire brush it. Then what treatments should I do to preserve the natural color?
I would recommend corn cob blasting it. You may have to grind it afterward. There is nothing that will really preserve the ”natural” look. You need to put some sort of stain on it that has pigment to help stop the UV from breaking it down. Do not use any CWF or Thompsons Weather Seal. It can promote black mold to grow on log homes.
