The trend towards high-quality living surfaces is steadily increasing in structural timber constructions, especially when using cross-laminated timber. In order to keep the visible surface permanently crack-free, a correspondingly low target moisture level must be set in the wood during manufacture. However, the one-component polyurethane adhesives used for production require a certain amount of water to cure. Surface conditioning attempts to compensate for the lack of moisture and the associated effects being scientifically investigated and optimized in the course of the research project OptiPUR.
