A method for repairing and lustering defects on a hydrophilic coat surface is reported. The method comprises the steps of applying a buffing composition on a hydrophilic coat surface; and buffing the hydrophilic coat surface to which the buffing composition has been applied. The buffing composition is an aqueous composition which comprises water and a water-soluble high-boiling- point liquid organic compound, and further comprises either a combination of abrasive particles and a dispersant, or lustering agent, or the both. The method allows for the removal of defects on a hydrophilic coat surface with good finish after repairing and without deteriorizing the antifouling function of the hydrophilic coat against urban fouling substances.

L'invention concerne un procédé de réparation et de lustrage de défauts sur une surface de revêtement hydrophile. Le procédé consiste à appliquer une composition de polissage sur une surface de revêtement hydrophile et à polir cette surface sur laquelle la composition a été appliquée. La composition de polissage est une composition aqueuse qui contient de l'eau et un composé organique liquide hydrosoluble à point d'ébullition élevé, et qui contient également soit une combinaison de particules abrasives et un agent dispersant soit un agent de lustrage ou les deux. Le procédé permet l'élimination de défauts présents sur une surface de revêtement hydrophile, bénéficiant d'une bonne finition après réparation sans détérioration de la fonction anti-salissante du revêtement hydrophile au contact de substances salissantes.
