A device applies a coating to a surface of an turbomachine annular casing, wherein the casing has an abradable layer obtained by polymerising a resin. The device includes first support means and, optionally second automated means movable relative to the first support means. The automated means includes means for depositing said resin on the surface of the casing. The automated means further includes means for spreading the resin on the surface of the casing, and means for unwinding a plastic film that is intended to be interposed between said spreading means and the resin.
