Description

Always read and follow all label directions. For Exterior Use Only. Tenino Copper Naphthenate contains 2% copper as metal as an oil-borne solution labeled for General Use. Ready-to-use solution one gallon will provide coverage of 100 - 300sq ft. It is both toxic and repellant to termites, and provides protection against wood decay with superior water repellent qualities of an oil-borne wood preservative. Commonly used to treat pole voids, bolt-holes, end-cuts and pole tops it requires no mixing or dilution and may be applied by brush to almost any wood product that needs to be protected from the elements. Tenino meets AWPA Standard M-4, and should be used to fulfill field treatment requirements of IBC 2303.1.9, and IRC R317.1.1 whenever pressure treated lumber is cut, or drilled. The limited warranties of many pressure treated lumber products are only valid when end-cuts and drill holes have been treated with Tenino. Protects bridge timbers, barn timbers, Glu-lam beams, salt storage domes, protector boards and highway railings and sign posts (Use in any DOT right-of-way as mandated by AASHTO). Tenino is best used to supplement pressure-treated preservative wood protection in aggressive hazard class environments envisioned in AWPA Use Category 4, 4B,4C.
