Résumé : |
To quantify the effect of preweathering of new wood surfaces on subsequent finish performance, unfinished wood siding was exposed outdoors for four or eight weeks. Following this preweathering, the specimens were finished with a variety of finishes and placed outdoors again for several years (weathered). The finished specimens were evaluated annually to determine the effect of preweathering on finish performance. The durabilities of 30 different finish systems, consisting of six finishes and five substrates, were evaluated over a five-year period. The wood species were primarily hardwoods and dense softwoods. For these dense species, which weather slowly, a few weeks of preweathering decreased paint performance. The effect of preweathering varied depending on the lenght of time the siding was preweathered, wood species, surface roughness, and finish. The results of the weathering were compared with the results of adhesion testing of similar panels preweathered before finishing. |
