The use of wood outdoors as a construction and decorative material is increasing, requiring wood with high durability and more intensive treatment to extend its service life, one of which is the application of a finishing coat. This study aims to evaluate the quality of commercial superhydrophobic finishing materials, namely Woca Denmark's Exterior Wood Shield and Propan Ultran Lasur Laser EL-501, on teak (Tectona grandis Linn.F) and mahogany (Swietenia mahagoni Jacq) wood. The study was conducted using an experimental method with a completely randomized factorial design with two factors, namely wood type and finishing material type. The parameters tested included water absorption, wood dimensional stability (expansion and shrinkage), and wood surface wettability. Water absorption was tested based on the percentage of water uptake, dimensional stability was determined through the tangential/radial (T/R) expansion and shrinkage ratio, while surface wettability was tested using the sessile drop method through water contact angle measurement. The results of the study show that the application of finishing materials affects the improvement in the quality of teak and mahogany wood. The Propan Ultran Lasur Laser EL-501 finishing material produced the lowest water absorption value compared to Woca Denmark and the control. All treatments produced a T/R ratio value of less than 2.0, indicating that the stability of the wood dimensions was stable. In addition, wood that was finished showed lower moisture absorption properties compared to untreated wood.
