1, Liang Ming Zhu Ming is a prominent component in the building structure. Painting Liang Ming Zhu Ming and the wall with light gray can highlight the sense of lines and texture of Liang Ming Zhu Ming, and the whole space looks brighter, more transparent and more concise.

2. The wall is not cleaned: before the wall is painted and fixed, it needs to be cleaned to remove impurities such as oil, dust and water stains, so that the wall is dry, flat and smooth, so that the wall curing agent can better penetrate and adsorb on the wall and enhance the hardness and durability of the wall. If the surface treatment of the wall is not clean, the wall curing agent can not fully penetrate and adsorb on the wall, resulting in poor curing effect of the wall and easy cracking and falling off.

3. Improper materials and construction methods: the materials and proportion of wall curing agent, as well as construction methods and techniques, will directly affect the wall curing effect. Using inferior curing agent, or improper proportion and irregular construction will affect the penetration and adsorption effect of curing agent, resulting in poor curing effect of wall. Uneven and inadequate construction will also lead to poor curing effect of the wall surface, which is prone to local cracking and falling off.
