Increasing the Durability of the Exterior Coating System by Surface Sealing
Original language description
This study focused on assessing how treating oak wood by the technology of sealing surface pores with epoxy resin affects the performance of transparent coating systems when exposed to outdoor conditions. Over the exposure period, various parameters, including color, gloss, surface wetting, and both macroscopic and microscopic surface features, were consistently monitored. The samples were divided into two sets: one underwent pre-treatment and the second did not. Subsequently, four different coating systems were applied to the samples, consisting of two solvent-based coatings and two water-based coatings. The experiment lasted for two years and relied on natural weathering methods within the grounds of the Czech University of Life Sciences in Prague. The epoxy resin pre-treatment exhibited improved resistance across all coating systems. Analysis showed a significant divergence in gloss and color after 12 months of exposure to weathering, with little impact on surface wetting and sealing. However, after 24 months of weathering, no substantial differences were observed between sealed and unsealed surfaces. The most effective pre-treatment was rated in properties was seen in the water-based coatings.
