The utility model provides an aluminum template coating structure, which is characterized in that the outer surface of an aluminum template is coated with a demolding protective coating to replace a mold protecting agent coating and a demolding agent coating. The problem that a pitted surface appears on the surface of concrete due to the fact that a traditional release agent of an aluminum formwork adheres to slurry after losing efficacy is solved, the process of brushing two coatings of a formwork protecting agent and the release agent and the complex process that each layer needs to be manually repaired and polished are replaced, and the safety is improved due to the fact that thin coatings are solidified on the surface of the aluminum formwork. The utility model belongs to the technicalfield of building construction.
