Finishability of CCA pressure-treated wood

Informally Refereed

Abstract

Thus, a need arose for the development of surface finishes for CCA-treated wood that could address the special requirements of this substrate and provide protection against the ravages of water, sunlight, mildew, and other aspects of weathering and wear. Initially, this need was not addressed, most wood preserving companies had little expertise in surface finishes and most coatings manufacturers saw the CCA-treated lumber market as too narrow to justify major product development efforts. As a consequence, "all-purpose"-type products were sometimes shoe-horned into the CCA deck category with less than optimum performance results. In the past few years, however, the dialogue between the wood preserving and coatings industries has improved significantly. and there are now several quality finishes on the market designed specifically for use on CCA-treated lumber. The challenge today is to communicate to consumers. contractors. and architects the special requirements of coatings for CCA-treated lumber and the proper techniques for their application.
