This research is a comparative analysis of the surface gloss of concrete depending on the coating material added to the cast, and includes analyses of the surface gloss of specimens made of cement mortar, with and without the addition of superplasticizer. In terms of coating material, the 7th material, which is part of a liquid packaging material, was shown to have the highest gloss, and was followed by the 3rd material, which uses transparent film. As the level of gloss is shown to vary depending on the material used for the coating film, it can be interpreted that the surface gloss can differ depending on surface particles and chemical composition factors. To make a concrete surface smooth, it is more effective to use a coating material with impermeability and a highly dense surface.
