Woodworkers struggle to achieve correct viscosity when diluting water-based oil-modified polyurethane finishes

Professional and hobbyist woodworkers frequently encounter confusion about the proper dilution ratios and techniques for water-based oil-modified polyurethane, leading to application failures, wasted materials, and ruined projects. Current product instructions are often vague or incomplete, and online resources provide conflicting guidance, forcing woodworkers to rely on trial-and-error experimentation that damages their work and increases costs.
