- In this study, pine and beech sapwood samples coated with 12 different waterborne acrylic resin coating systems were exposed to natural weathering in Trabzon, Turkey. The natural weathering test continued for 18 months. In these coating systems, water in different proportions, boric acid, two different acrylic resins and three different UV absorbers supplied by BASF were used. The aim was to compare the durability of 12 different coating systems in natural weathering in terms of colour change, surface roughness and macroscopic evaluation. These test methods were used to evaluate the appearance and physical properties of the coatings after the natural weathering test. The results led to the selection of the best coating formulation for wood durability in natural outdoor conditions. The appearance and physical values after 18 months of the weathering test showed that boric acid increases the durability of the coating for use in outdoor conditions. Additionally, the coating formulation containing especially acrylic resin and Tinuvin 400 DW provided the highest durability against outdoor conditions.
