Sta Brite® R Wood Protector

House treated with CuSol-5

Specially formulated pesticide for exceptional exterior wood preservation.

CuSol®-5 is our newest water-borne, copper-based preservative for general wood preservation and cedar shake shingles, but without the offensive odor of copper naphthenate.

In fact, it’s designed for all exterior wood exposed to moisture or weather, including window frames, wood shake and shingle roofs, doors, siding, fencing, arbors and many more applications. After treatment, CuSol-5 helps protect wood from attack by termites and powder post beetles. It also helps control decay fungi and destructive rot-causing organisms. Plus it has low phytotoxicity, so it’s suitable for wood in greenhouses and nursery flats.
