Abstract

Metal or concrete surfaces are coated firstly with a mixture of hydraulic cement and a latex or emulsion of a film-forming natural or synthetic thermoplastic organic material with or without a finely divided aggregate, then with a continuous adherent layer of a film-forming thermoplastic material which is compatible with the film-forming material in the first coating, and finally with a layer of polyvinyl chloride plasticized with an organic polysulphide rubber. The final layer may be in the form of a so-called reverse-phase paint. The thermoplastic material may be polyvinyl chloride, natural rubber, synthetic rubber such as butadiene-acrylonitrile copolymer or polysulphide rubber, polyvinyl acetate or mixtures thereof. A preferred composition uses polyvinyl acetate emulsion, "Ciment Fondu" (Registered Trade Mark) and sand for the first coating, and polyvinyl acetate containing up to 20% of a plasticizer for the second. The first layer may be applied as a trowelling composition, and the subsequent layers by brushing or spraying. The method may be used for repairing corroded steel tanks by applying the coatings to the corroded parts; or for coating the interiors of concrete storage tanks.ALSO:Metal or concrete surfaces are coated firstly with a mixture of hydraulic cement and a latex or emulsion of a film-forming natural or synthetic thermoplastic organic material with with or without a finely divided aggregate, then with a continuous adherent layer of a film-forming thermoplastic material which is compatible with the film-forming material in the first coating, and finally with a layer of polyvinyl chloride plasticized with an organic polysulphide rubber.
