Concrete column with coating

The invention discloses a concrete column with a coating and relates to the technical field of architecture. The concrete column with the coating comprises the concrete column. The surface layer of the concrete column with the coating is sprayed and coated with a liquid rubber spray paint coating. The concrete column with the coating has a simple structure. The sprayed and coated liquid rubber spray paint coating has strong chemical resistance, strong acid resistance, alkali resistance and salt resistance; the anti-puncture performance is high; the film formation thickness is greater than 2mm and the concrete column with the coating has excellent self-recovery capacity; water is non-permeable between an adhesive film and a substrate, so that the skin-type waterproof requirement is really met; the concrete column with the coating has good ozone aging resistance and uvioresistant performance and has design life being over 50 years; the concrete column with the coating has very good affinity with all conventional waterproof materials and is totally adhered to most of base structures; the concrete column with the coating is time-saving and labor-saving and has high efficiency; and the basic construction cost can be saved and reduced.
