The inner wall is made of gypsum mortar fiber, which can be washed with water without dust, falling, slight impact and no dust. It decomposes at room temperature or high temperature, is non-toxic and has high chemical stability. Mix the light plaster mortar with water for about 10 minutes and let it sit. After 5 minutes, you can scrape it onto the wall in batches. Usually shave twice. When scraping for the second time, you must wait until the first wall is dry before scraping.
The plaster layer and the base layer are firmly combined without hollowing, hydration micro-expansion, crack suppression, rapid hardening, and the strength of the hydration process increases, and Easy to mechanize plastering. It has the advantages of convenient construction, high efficiency and less floor dust. It has respiratory function, is non-radioactive, antibacterial, non-toxic, and is a green building material.
The construction environment temperature of plastering projects should generally be above 0℃. When the ambient temperature is below 0°C, heating, insulation or antifreeze measures should be taken, and a winter construction plan should be formulated. When the indoor ambient temperature is below 0℃, construction is prohibited. During winter construction, a dedicated person should be responsible for the opening and closing timing of doors and windows to enhance ventilation and dehumidification effects.
In the plastering operation of light gypsum mortar, the main basis is to determine the plastering sequence from the side of the door to the entire wall, first up and down. Regular concrete ceilings can be plastered in one go. Depending on the flatness of the bottom of the wall, set signs or reinforcement bars. The spacing between vertical bars should be 1.2-1.5m and the width should be 0.03-0.05m.
Unreasonable proportions of lightweight gypsum mortar formulas for interior and exterior walls and interactions between admixtures and other components in the formula can also lead to powder removal. Here, we must choose manufacturers with rich production and research experience. During the production process, uneven mixing is also an important reason for the desalination of lightweight gypsum mortar for interior and exterior walls.
During the construction process of building exterior walls, the quality of gypsum will change due to incorrect construction methods and methods of gypsum. If the waterproof coating is not applied immediately or the production date of the waterproof material is far from the time of entry, the following quality changes may occur. </p
