Bor8 Rods (previously known as Impel Rods) are a highly effective preservative system for the prevention and control of fungal decay (log rot) and many destructive insects in wood structures. When moisture contents reach levels suitable for decay (i.e. around 25%), Bor8 Rods slowly dissolve and begin to diffuse throughout the wood. Under 25%, the preservative becomes dormant.
Directions: Drill appropriate sized holes to accommodate the predetermined number and size of Bor8 Rods required; Insert the suitable size and number of Bor8 Rods into the holes; and seal the hole with a treated wooded dowel, wood filler or caulk. Drill holes 1/16" greater in diameter than the preservative rods to result in a snug fit. This will ensure proper
diffusion in all directions from the rod. In addition, leave a minimum of 1/8" of head space between Bor8 Rods and hole plug to allow for expansion. After installation, paint or any other type of surface coating may be applied to the wood if desired. Install Bor8 Rods in the general vicinity of where the potential for decay is greatest or where decay exists. Bor8 Rods can be inserted through any wood surface depending on access, in either
a staggered, linear or angled pattern. Start at 1" from a joint or the
end of the wood and cover the entire affected length. Linear spacing
along the grain should not exceed 12" and spacing across the grain
should not exceed 3" on the center. Cannot be sold or shipped to Canada
