    The company's Wolmanized L3 outdoor wood preservative is non-metallic and carbon-based. The biocides used in the preservative are known to degrade in soil, so they do not accumulate, the manufacturer says. Applied to wood, the treatment resists termites and fungal decay, and comes with a limited lifetime warranty. In addition, wood treated with Wolmanized L3 retains its natural color with no green tint. Wolmanized L3-treated wood is appropriate only for out-of-ground use. 678-627-2000. www.wolmanizedwoodl3.com.
