The invention relates to the technical field of building construction, and discloses a gypsum-based light plastering material, which comprises the following raw materials in parts by weight: 400-600 parts of natural white gypsum powder, 150-200 parts of heavy calcium powder, and 200 parts of white sand. -400 parts, 1-2 parts of retarder, 1-2.5 parts of thickener, 1-2 parts of plasticizer, 5-10 parts of anti-cracking agent, 0.1-0.3 parts of air-entraining agent, and 1-3 parts of pigment. It solves the problems of traditional plastering plaster that cannot be delivered at one time, the bonding strength is insufficient, the color is uneven after molding, the surface is rough, the coating rate is low, and the surface layer strength is insufficient. |
