Wood is an irreplaceable structural and biodegradable material, which is subject to swelling, shrinkage, significant deformation of structural elements, and products when its moisture content changes. This paper proposes wood surface modification with reactive copolymers based on glycidyl methacrylate and alkyl methacrylates to impart superhydrophobic properties with initial contact angles up to 166 degrees. Scanning electron microscopy and energy dispersive X-ray spectroscopy were used to study the features of polymer coating formation and to determine the modifier penetration depth, which was more than 1000 mu m. It has been shown that copolymers do not fill the initial capillary system of wood. Modified wood is characterized by stable water-repellent properties with low-water diffusion rates, with the water absorption rate reduced by more than three times compared to that of initial wood. Polymer coatings provide water repellency, retain the appearance of original wood, and provide increased buoyancy.
