There are cracks in the fine stone concrete after solidification. The construction progress is slow, the labor intensity is high, the ground is difficult to level, and the weight is heavy. It is easy to cause serious pollution to other products during the construction process, contaminate the wall during the construction process, and it is difficult to protect the finished product during the construction process. Lightweight gypsum mortar is two-thirds of the weight of concrete.
Mix the lightweight gypsum mortar and let it sit for 15-20 minutes. During this process, the additives in the lightweight gypsum mortar can be completely dissolved. After dissolving, it can be painted on the wall to avoid color difference and bubbles. If the gypsum mortar does not fall off, it means it is a high-quality lightweight gypsum mortar, otherwise it is an inferior lightweight gypsum mortar.
If it is an unknown lightweight gypsum mortar, I cannot guarantee its quality. Some toxic substances may be added during the production process. Although it does not have formaldehyde, it does contain other toxic substances, so I do not recommend that you buy this lightweight plaster mortar.
Adding water-retaining agent to light gypsum mortar has good water-retaining effect. When gypsum dissolves in water, it locks in a lot of moisture. At this time, a large amount of water condenses into water masses. With stirring, a large amount of water is separated out, so a common problem is that the more you stir, the thinner it becomes.
Mortar is a surface filling material used to pretreat building surfaces before latex paint or wallpaper construction. It is constructed over latex paint. The main purpose of mortar is to fill the pores on the building surface, correct the curve deviation of the building surface, and lay a good foundation for obtaining a uniform and smooth working surface.
