Our product quality is highly praised, with abundant supply and a wide range of applications. We specialize in solving problems such as insufficient strength of cement plaster mortar and wall sanding and flaking. Changxin Building Materials' wall hardener and morning concrete agent are suitable for cement plaster mortar layers and cement products with substandard cement grades, insufficient mortar strength, and raised sand and dust on leveling layers. The material is easy to apply, requiring only spraying, which can increase the strength of cement plaster mortar by 10~60% in 1~2 days.

In construction projects, concrete wall plastering is a common process. However, sometimes we encounter issues with sanding off after plastering. This not only affects the aesthetic appeal of the wall but also leads to waste of wall materials. This article will discuss the problem of sanding off in concrete wall plastering from four aspects.
I. Selection of Construction Techniques
In most cases, the reason for concrete wall plaster chalking is due to improper selection of construction techniques. Before starting the plastering work, it's essential to moisten the concrete wall to enhance the bond between the wall and the plaster material. Secondly, opting for early-strength plaster mortar can be effective, as it forms a gel more quickly during cement hydration, thereby increasing the bond strength between the wall and the plaster mortar. Additionally, choosing the right flexible adhesive is also an effective method to address this issue.
Section II: Selection of Wall Materials
The choice of wall materials is crucial for solving the problem of sanding off on concrete walls. Firstly, we can opt for adhesives and waterproofing agents with good bonding properties to enhance the adhesion between the wall and the plaster material. Secondly, considering the characteristics of concrete walls, choosing alkali-resistant and moisture-proof plaster mortar is effective, as it can significantly reduce moisture penetration through the wall, preventing the sanding off issue. Moreover, selecting plaster mortar with fiber-reinforcing materials is also an effective solution; these fibers can increase the bonding strength of the mortar and prevent cracking of the wall.

III. Improvement in Construction Techniques
Improvements in construction techniques can address the root cause of the sanding problem in concrete wall plastering. Firstly, we should ensure that wall preparation before construction is thorough, such as cleaning walls and repairing defects, to maintain the wall's flatness and smoothness. Secondly, construction workers should master the correct plastering techniques, ensuring the plastering material is evenly applied to the wall and proper measures for controlling the plastering thickness are taken. Additionally, avoiding extensive continuous work during construction can reduce the shrinkage and cracking of the mortar, thereby reducing the sanding on the wall.
Section 4: Wall Maintenance Measures
Wall maintenance measures are crucial for preventing the recurrence of sanding issues on concrete plastered walls. Firstly, after plastering, we should promptly moisten the wall to promote the hydration reaction of the plastering material. Secondly, preventive measures should be taken after plastering, such as applying a protective film over the plastered wall and attaching a mesh fabric, to protect the wall from external damage. Additionally, regular inspections for cracks and peeling on the wall, followed by timely repairs, can effectively extend the lifespan of the wall.
Summary:
Dust falling off concrete wall plaster is a common issue in construction. To address this, it's necessary to consider multiple aspects, including the selection of construction techniques, wall materials, improvement of construction methods, and maintenance measures for the walls. By choosing appropriate construction techniques and materials, enhancing the construction methods, and implementing proper wall maintenance, the problem of concrete wall plaster dusting can be effectively resolved, improving the quality of construction and the lifespan of the walls. It is hoped that the solutions provided in this article will be helpful in dealing with the issue of concrete wall plaster dusting.
