The problem with additives: The most commonly used fiber in putty is cellulose ether, which mainly serves to retain water. When adding cellulose ether, the quality and reliability of cellulose ether should be selected. Poor quality, poor putty moisture content, and difficult scraping. The viscosity of cellulose ether is also moderate. If the viscosity is too high and the batch weight is too heavy, it is difficult to work. If the viscosity is too low and the water retention is insufficient, it is easy to dry. Mix 200kg of calcium ash putty powder and 3-4kg of 40000 hydroxypropyl methyl cellulose with viscosity. In addition, we can consider adding wood fibers, which are cheap, water, and thickeners, and adding a small amount of starch ether to increase construction. Batch shaving is light and sticky.

The rapid drying of putty powder on walls is mainly influenced by external factors, internal factors, and batch scraping thickness. The main external factors are the dryness and wetness of the walls, as well as weather conditions such as temperature, humidity, and sunlight. The main reason is the ratio of raw materials and additives, and the thickness of the ingredients also affects the drying speed of the putty wall.

Wall too dry: If the wall is too dry, it will absorb a large amount of moisture from the putty, and the putty will quickly dry out after the putty wall. In this case, check the moisture content of the wall before spraying putty on it, as there is no clear water before construction.

High temperature: High temperature, strong light, fast evaporation rate of water, dry putty behind the wall. Especially in summer, it is important to avoid the high temperature and light intensity of putty and choose to work at low temperatures in the morning and evening. In addition, when adding raw materials, the amount of cellulose ether should be slightly increased to increase water retention and reduce excessive evaporation of water.

Quality issues with putty: Some manufacturers use cement and lime in putty to save costs. The application of high alkali cement in putty can cause excessive hydration rate, resulting in rapid plastic loss and shortening the construction period. Calcium silicate has a high water absorption capacity. If a large amount is added, it will cause dry putty on the wall. Therefore, when configuring raw materials, reduce or avoid using high alkali cement and decrease the content of calcium ash. If there is no special purpose, in general, ordinary putty only needs to add 150-200kg of calcium ash.
