Hi Kathy...I'm all ears!
Where are you building ?
If you send me your e-mail address I will send you some detailed info on how to prep and stain logs and log siding exterior and interior including some excellent suggestions on design, layout, interior finih products. I am not a builder and I do not sell products. I am a log home owner.
Also, check out gemini-coatings.com as an additional option when selecting stains for your huge investment. Be sure you do as much research as possible before building. Design your home with the first row of logs up at least 24 to 30 inches above final grade, large overhangs - at least 30 inches on the side and 6 to 8 feet on the ends. Install rain gutters and do everything you can at the design level to keep the logs dry once the home is built.
Threat all wood, OSB, 2x4's 2x6's, 2x12's plywood, everything with Timbor or Borada-D ( borax salt ) to deal with insectrs, wood rot, etc.
Send me your e-mail address and I will forward additional info to help you become more well informed.
