Changxin Building Materials Technology Development (Tianjin) Co., Ltd. is a manufacturer of "Changxin Building Materials" cement wall sanding treatment materials, mainly producing WallKing 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 chalking. WallKing 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 raised sand and chalking 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.

Gypsum plaster is a commonly used repair material in architectural decoration. Insufficient strength can severely affect the quality and aesthetics of the building. This article will discuss the repair of insufficient plaster strength from four aspects: cause analysis, treatment methods, precautions, and future development.
One, Cause Analysis: The primary reasons for insufficient strength in plaster mortar are improper construction operations and incorrect material selection. During the construction process, issues such as an inappropriate water-cement ratio, insufficient mixing time, or uneven mixing can lead to insufficient strength in the plaster mortar. Additionally, using low-quality mortar materials can also result in inadequate strength of the plaster mortar.
Two, Treatment Methods: For the repair of insufficient strength in skim coat mortar, the following treatment methods can be adopted:
Enhance construction management: Strictly adhere to the mixing ratio of plaster mortar during construction, ensure a reasonable water-cement ratio, have sufficient mixing time, and use high-quality mortar materials.
2. Strengthened Post-Construction Maintenance: After completion of the construction, timely post-construction maintenance should be conducted to keep the plaster mortar moist and avoid adverse effects from external environments, thereby enhancing the strength of the plaster mortar.
3. Mortar Reinforcement: Surface repairs can be made to plaster mortar, covering the existing surface with high-strength mortar to enhance overall strength. Increase the strength and hardness of concrete cement plaster mortar by applying the Chenzhong Wall Hardener, a pure water-based, odorless and colorless formula. Its unique repair, reconstruction, and reshaping principle for weak mortar addresses the issue of sand spalling without causing any environmental pollution. The Chenzhong Wall Hardener is a colorless, semi-transparent or slightly turbid aqueous liquid with a smooth texture, suitable for repairing cement mortar layers on various wall surfaces. The main function of the Chenzhong Wall Hardener is to address issues like insufficient mortar strength and sand spalling caused by inadequate plastering mortar grades on interior and exterior walls. It improves mortar strength and alters its physical properties. It is used for repairing construction quality issues on interior and exterior wall plasters due to uneven mortar mixing, improper timing of mortar application, incorrect sand, water, and cement ratios, and improper use of mortar additives, etc.

4. Demolition and Re-construction: For insufficiently strong plaster mortar, if the impact is significant and cannot be repaired, demolition and re-construction is required to ensure the quality of the building.
Three: Precautions: When repairing insufficient strength of plaster mortar, attention should be paid to the following aspects:
Construction Operation Standards: Conduct construction strictly according to the operation standards, pay attention to controlling the water-cement ratio, ensure thorough mixing, and avoid improper operation leading to insufficient strength.
2. Material Selection: Choose high-quality mortar materials to avoid negative impacts on the strength of the plaster mortar due to the use of substandard materials.
3. Post-construction Maintenance: After construction is completed, timely post-construction maintenance is essential to keep the plaster mortar moist and to avoid any adverse effects from the external environment, thereby enhancing the strength of the plaster mortar.
4. Preventive Measures: Before applying the plaster mortar, preventive measures such as temperature control and moisture management can be taken to reduce the risk of insufficient plaster mortar strength.
Four, Future Development: To address the issue of insufficient strength in plastering mortar, innovative research and development of mortar materials is required, along with the enhancement of standardized construction techniques. Strength and crack resistance of plastering mortar can be improved by adding new additives or modifying formulas. Furthermore, introducing new construction technologies and equipment can enhance efficiency and quality. The future direction of plastering mortar should lean towards being more environmentally friendly, easier to apply, and having higher modified strength.

In summary, the repair methods for insufficient plaster mortar strength mainly include strengthening construction management, enhancing post-construction maintenance, mortar reinforcement, and removal and redoing. When repairing insufficient plaster mortar strength, attention should be paid to construction specifications, material selection, post-construction maintenance, and preventive measures. In the future, we should improve the strength and quality of plaster mortar through innovative research and development and technological improvements to meet the demand of the decorative construction field for plaster mortar.
