Wood preservative products are those that claim to control wood degradation problems due to fungal rot or decay, sapstain, molds, or wood -destroying insects. Both the treatment process and the use of treated -products can result in exposure to pesticides for both people and the environment. Apart from structural wood preservation measures, there are a number of different preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood , timber, wood structures or engineered wood. Classic Clear Above Ground Wood Preservative (Case of 4) for use on above-ground wood installations (especially non- pressure - treated lumber) to protect the structural integrity.

The sawdust from pressure - treated wood is an irritant to the eyes, skin, and nose. Some low level leaching (the chemical preservative leaking from the wood ) can also be a problem with indoor projects. Treated wood tests are intended to provide relative corrosion information of items in contact with preservative treated woods and typically use humidity and elevated temperature to accelerate corrosion rates. For fully exposed decks, a water-repellent sealer or a penetrating semi-transparent stain may provide the best finishing solution, even on wood that has been pressure treated with preservatives.
