Use borate based wood preservatives like Bor8 Rods or CobraRods to protect your logs and timbers from the inside-out, and Armor-Guard, Boracol, PeneTreat, or Shell-Guard RTU to treat from the outside-in. To protect your log ends use our End Grain Sealers. Use Sapstain Controls to protect your newly cut logs from blue-stain fungus. Pentacryl is used to stabilize and keep green wood from cracking (great for furniture makers). If you are looking for the gray rustic look use LifeTime or Sansin Wood Sealer to turn bare wood gray. We also carry wood primers for Perma-Chink stains (Prelude). For log home stain additives, click here.
