I. Cause Analysis: Why does the wall plastering layer develop sanding issues?
The problem of sanding on wall plastering commonly occurs on rough and loose plaster layers. The reasons for this issue mainly include the following aspects:
The base treatment of the plastering layer is not solid enough. If the wall base has not been sufficiently reinforced, such as lack of sanding, incomplete cleaning, or absence of undercoat application, the plastering layer will struggle to adhere tightly, leading to the occurrence of sanding issues.
2. Utilizing substandard plastering materials. If inferior plastering materials are chosen, they typically have poor adhesion and stability, leading to sanding issues upon use.
3. Improper construction operations. Failure to properly mix the material ratios and apply the correct plaster thickness during the plastering process, insufficient density of the mortar, or uneven pouring and construction of cement mortar can all lead to sanding issues.
Solution 1: Pre-strengthen the wall base layer to enhance the adhesion of the plastering layer.
To prevent the occurrence of sanding issues on the plaster layer, we must first strengthen the treatment of the wall base. Here are several methods to reinforce the wall base:
Prepare wall base: Remove oil stains, dust, and other debris from the wall base, ensuring the surface is dry and level.
2. Base Coating Treatment: Perform a scraping treatment before applying the plaster layer on the wall base to enhance the adhesion between the wall and the plaster layer.
3. Wall Coating Binder: Utilize wall binder to enhance the compactness and adhesion of the wall base, preventing the occurrence of sanding issues.

III. Solution Two: Selecting the right plastering material to enhance the stability and flexibility of the plaster layer
Choosing the right plastering material is crucial for addressing the issue of sanding. Here are a few points to consider:
Choose reliable plastering materials: Opt for quality-assured, widely-used plastering materials and ensure the materials' certification and supplier's reputation.
Mixing ratio for jointing plaster materials: Mix the jointing plaster materials accurately according to the manufacturer's specified ratio to ensure the stability of material properties.
3. Utilize enhanced flexibility plastering materials: Opt for plastering compounds with added fiber materials to enhance the flexibility and stability of the plaster layer, preventing the occurrence of sanding.
Four: Solution Three: Proper construction and maintenance to extend the lifespan of the plastering layer.
Proper construction and maintenance measures are crucial for extending the lifespan of plaster layers. Here are some points to consider:
Pay attention to the thickness of the plaster layer: Reasonably control the thickness of the plaster layer as required to avoid excessive thickness causing wall sanding.
2. Mortar Curing: After the plastering work is completed, timely curing is essential to prevent the mortar from drying too early, which may affect the adhesion of the plaster layer.
3. Strengthen Construction Process Quality Inspection: Throughout the construction process, enhance supervision and quality checks of the construction personnel to ensure the standardization and rationality of construction operations.
In summary, to address the issue of sanding on wall plastering layers, we must focus on reinforcing the base layer, selecting the right plastering materials, proper construction, and maintenance. Only by employing these methods comprehensively can we maintain the stability and flexibility of the wall plastering layer, prevent the occurrence of sanding, and extend the service life of the plastering.
