Water-based preservatives like copper azole leave wood with a clean,         paintable surface after they dry. Copper Azole is registered for treatment         of millwork, shingles & shakes, siding, plywood, structural lumber, fence         posts, building and utility poles, land and freshwater piling, composites,         and other wood products that are used in above-ground, ground contact         and fresh water as well as in salt water splash (marine) decking applications.
