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 Zhaonzhong wall concrete agent. Known for its high-quality products, ample supply, and wide application, our solutions effectively address issues such as insufficient cement plaster砂浆 strength and wall sanding and flaking. The WallBoss wall hardener and Zhaonzhong wall concrete agent are suitable for cement surfaces that do not meet standard specifications, insufficient mortar strength, and leveling layers with sanding and flaking. The materials are easy to apply, requiring only a spray coating, and can increase the strength of cement plaster砂浆 by 10~60% in just 1~2 days.

How to Determine the Severity of Wall Chalking
As a key criterion for assessing the severity of wall dusting, we first need to observe whether the dust is accumulating in large areas on the walls. If the wall shows obvious dullness or yellowing, it indicates that the thickness of the dust on the wall surface has exceeded the normal range. Moreover, we can gently tap the wall, and if a large amount of dust falls off, or there are noticeable residues after touching the wall with your hand, that means the wall dusting is quite severe.
How to Clean Wall Dust
Use a soft-bristled brush for cleaning
We can use a soft-bristled brush to gently remove dust from the walls, one speck at a time. When painting, be sure to use a brush with a moderate stiffness; too stiff a brush may damage the wall. Gently hold the handle of the brush and slightly angle the bristles at the head to better clean the wall dust.
2. Wipe with a clean cloth
When cleaning off wall dust, we can also opt to use a cleaning cloth to wipe the walls. Unlike a soft-bristled brush, apply moderate pressure while wiping to avoid scratching the surface. Additionally, pre-moisten the cloth to enhance the cleaning effect.

How to Prevent Wall Chalking
Tidy up indoor dust promptly.
To prevent wall dust, it's crucial to maintain a clean indoor environment. Regularly dust rooms, cleaning floors, furniture, curtains, and other items to ensure fresh air inside. Additionally, replace the air purifier and AC filter regularly to prevent dust buildup.
2. Reduce Window Opening Time
In daily life, minimize the time windows are open, especially in areas prone to sandstorms or near roads, to prevent outdoor dust from entering indoors. If ventilation is necessary, choose periods with good weather conditions and avoid strong winds.
Four: Repaint and skim coat treatment
If wall chalking is severe enough to not be resolved through cleaning, it's necessary to re-plaster the walls. First, use professional tools to thoroughly remove the old chalking layer from the walls. Next, apply a primer to the wall to enhance its adhesion to dust and the wall surface. Finally, after the primer dries, re-plaster the wall using the appropriate tools to ensure the stability and flatness of the chalking layer.
In summary, addressing the issue of chalking on interior and exterior plastered walls requires considering four aspects: the severity assessment, cleaning methods, preventive measures, and repainting procedures. Through scientific and rational methods, along with proper operations, we can effectively resolve the wall chalking problem, creating a clean and tidy living space for our customers.
