Lightweight gypsum mortar leveling is composed of lightweight aggregate, water reducing agent, water retaining agent, gypsum, retarder, fine sand, etc. in a certain proportion. The water addition ratio needs to be adjusted during use, and the water addition amount should be increased according to the actual leveling construction conditions to ensure the workability and applicability of the mortar.
Lightweight gypsum mortar and latex paint are more beautiful. Lightweight gypsum mortar powder is mainly used to fill walls. The finished surface is smooth and flat and painted with latex paint, very nice, imitation porcelain combined with filler and paint. Until it's finished, imitation porcelain walls will have the effect of ceramic tiles, smooth but not high.
In decoration, putty gypsum powder is generally used for foundation treatment such as filling joints and correcting internal and external corners. For the first time, I found even putty on the walls of the rough house. The plaster has good adhesion and is not easy to fall off. Generally, it is not used directly to find ordinary walls. Talc powder should also be added, otherwise the construction will be inconvenient.
After the surface of the exterior wall putty is dry, it should be polished properly and watered thoroughly. General maintenance is divided into two or more times. If necessary, please use a transparent sealing primer mixed with water (1:5) as the second watering liquid, the effect will be better.
The shedding and graying of lightweight gypsum mortar powder are currently the most common problems after putty construction. To understand the reasons for the powder loss of lightweight gypsum mortar, you must first understand the basic raw material composition and maintenance principles of lightweight gypsum mortar, and then analyze the dryness, water absorption, temperature, etc. of wall putty construction, and the weather is dry.
