The invention is related to a method for coating a roll, in particular of rolls in size presses and coating machines, in which method a resilient polymer coating is fitted onto the roll frame. A polymer or a mixture of polymers is used as the matrix material far the coating material. Before the material is fitted onto the roll frame, oxides and/or carbides and/or sulphates are mixed into the matrix material to improve the wear resistance and the process-technical properties. Various fillers and admixtures are employed to improve the manufacturing-technical properties. The substantially homogeneous coating material thereby formed is spread onto the roll frame as a substantially even and homogeneous layer. The invention is also related to a roll coating.
