The paper presents a short description of the model of the phenomenon of droplet spreading in presence of a liquid film, as well as the experimental facility, calculations methodology and results of experimental research concerning determination of the boundary angle at which droplet begins to slide on the horizontal or inclined surface of the plate. Values of boundary angle have been applied to estimate the microscopic dynamic advanced angle of the droplet on the flat surface in presence of a liquid film.
