The invention relates to a method for correcting flaws produced in the grain layer (2) of grain leather (1) by indentations by pressing, by means of an application roller such as a squeegee, into said indentations an aqueous, optionally slightly foamed dispersed synthetic resin which contains miniscule compact particles and then drying the leather (1). The surface (4) of the grain layer (2) is then subjected to pressure and heat at a temperature of at least 100 °C by means of a pressure roll rolling off on said surface, thereby producing in the indentations a synthetic mass in which microspheres (5) formed from the compact particles are present and which completely fills in the indentations.
