Changxin Building Materials Technology Development (Tianjin) Co., Ltd. is a manufacturer of "Changxin Building Materials" cement wall sanding treatment materials, mainly producing WallBoss wall hardener and Zhaoming wall concrete agent. Our product quality is highly praised, with ample supply and a wide range of applications. We specialize in solving issues such as insufficient strength in cement plaster mortar, and wall sanding and flaking. Changxin Building Materials' WallBoss wall hardener and Zhaoming wall concrete agent are suitable for cement plaster mortar layers and cement products on walls and columns with substandard cement grades, insufficient mortar strength, and sanding and flaking on leveling layers. The materials are easy to apply, requiring only a spray application, which can increase the strength of cement plaster mortar by 10~60% in 1~2 days.

I. Cause Analysis and Preventive Measures
Wall sanding refers to the phenomenon of mortar peeling or bulging on walls, which affects the aesthetics and service life of the walls. To address this issue, we first need to analyze the cause of the sanding and implement corresponding preventive measures.
1.1 Weak foundation
A primary cause of sanding on wall mortar is an unstable base layer. To address this issue, first ensure the flatness of the wall base, remove loose mortar layers, and make repairs. During construction, it's also important to select appropriate exterior insulation materials and install them strictly according to the construction specifications. Additionally, reinforcing the wall can be achieved by using the sand-filled compacting method, where a certain proportion of cement and mortar is mixed and filled onto the wall to enhance the bonding strength of the structure.
1.2 Construction quality does not meet standards
Another cause of wall sanding is substandard construction quality. To enhance the wall's strength, we should pay attention to every detail during construction. Firstly, ensure the mortar bond between the wall and bricks is secure, using mortar with appropriate water-cement ratio and particle size. Secondly, pay attention to the thickness of the mortar pour, avoiding too thick or too thin. Thirdly, apply even pressure and angle when plastering the wall to ensure consistency and flatness of the mortar. To guarantee construction quality, carefully review the specifications for wall insulation construction and reasonably analyze the usage methods.
Wall Sanding Repair Liquid
2.1 What is wall sanding repair liquid?
Wall sanding repair liquid is a special paint that forms a protective film on the surface of walls, enhancing the bonding and compressive strength of mortar to prevent sanding. This repair liquid is extremely convenient to use, as it can be directly sprayed onto the wall after the wall construction is completed. Once dried, it forms a hard and smooth protective layer.
2.2 Composition and Characteristics of the Repair Liquid
The wall sanding repair liquid is mainly composed of resins and fillers. The addition of resins enhances the bonding and hardness of the repair liquid, while the inclusion of fillers improves its pressure resistance and wear resistance. Moreover, the repair liquid dries quickly, is odorless and non-toxic, posing no harm to workers or the surrounding environment.

2.3 Application Method for the Repair Liquid
The repair liquid spray application is very simple; just pour the repair liquid into the spray application equipment and then evenly spray it onto the wall. Due to the high viscosity of the repair liquid, it can effectively fill in the microscopic pores and fine cracks on the wall surface, enhancing the wall's compressive strength.

III. Methods for Handling Low Surface Strength of Mortar
3.1 Increase the bonding strength of the mortar
To enhance the surface strength of mortar, we can increase its bonding strength. A common method is to add a suitable bonding agent, such as polymer and fiber materials, to the mortar. These additives can fill the gaps between mortar particles, improving the bonding strength and durability of the mortar. Additionally, adjusting the mortar's mixture ratio to achieve proper moisture content can enhance its bonding power and hardness.
3.2 Enhance the compactness of the mortar
Another reason for low surface strength of mortar is insufficient density. To increase the density of mortar, a densifier can be used. The densifier enhances the particle filling within the mortar, making it more uniform and compact. Additionally, densifiers offer waterproofing and mold prevention, protecting the mortar from the effects of moisture and oxidation.
IV. Conclusion
Wall sanding repair liquid is an effective solution for wall sanding issues. By applying the repair liquid, the surface strength of the wall can be enhanced, preventing the occurrence of sanding. Moreover, to improve the surface strength of mortar, we need to address aspects such as the base layer's stability, construction quality, mortar's bonding strength, and compactness, and implement corresponding preventive and treatment measures. Only by combining construction quality and application techniques can the wall sanding problem be better resolved and the service life of the building extended.
