Board Defense: Borate (25 Pound)

Tim-bor is the inexpensive insurance every wood homeowner needs. When sprayed on bare wood, the borates in Tim-bor form a protective shell to defend against rot and wood-ingesting insects. It’s easy to use and EPA-registered. Tim-bor will not affect the color of the wood and is chemically compatible with all of Sashco’s stain, caulking, and chinking products.
