Monte Carlo simulation of the drop formation has been carried out for one-component and binary systems. A model of lattice liquid with vacancies was used. Activation energies for the interexchange between the atoms and the vacancies were calculated after counting all the nearest neighbors of both. The shapes of drops and wetting angles were studied for different interactions of atoms of the main component and an added component with the substrate. An active added component improves wetting but a very active component impedes spreading of liquid along the substrate. Some solutions were obtained for the cases when crystallization of one component or dissolution of the substrate took place. A crystal phase appearing on the substrate detains liquid spreading. A partially dissolved substrate does not restore its shape after crystallization.
