Job Site Storage and Handling
As with untreated wood, it is necessary to keep Advance Guard® Borate Pressure Treated Wood products dry by covering the material or storing the materials under shelter and elevating the material above the ground to allow for air circulation.
Sheathing should be covered as soon as practical after installation. If wetted during initial construction, allow materials to properly dry before permanently enclosing with felt, wallboard, etc.
After working with the wood, and before eating, drinking, and use of tobacco products, wash exposed areas thoroughly.
