The Plight of Annoying Floors: Dusting and Sanding
In daily life and work environments, the issues of dusting and sanding on old concrete floors are very common, and the resulting troubles cannot be underestimated. Walking into the workshops of some old factories, as machinery operates, dust and sand particles constantly rise with the vibrations and fill the air. This not only makes the workshop look dirty and messy but can also affect the operation of precision instruments, increase equipment wear and failure rates, impact product quality, and lead to a higher defect rate. If there are forklifts or other handling equipment in the factory, the sanding floor becomes loose, and forklifts can easily slip while driving, posing a severe threat to the safety of operators. Furthermore, to cope with the dust and sand, the workshop requires frequent cleaning, which not only increases maintenance costs but also distracts employees and reduces production efficiency.

Looking at residential communities, the floors of some underground parking lots also suffer from severe dusting and sanding. When vehicles enter and exit, the friction between tires and the ground quickly kicks up dust. Car owners have to cover their noses and hurry past, fearing they will inhale too much particulate matter. For residents living on the ground floor, indoor floors may face the same problem. No matter how clean you just swept, dust reappears shortly after. Hair, dust, and sand mix together, making it difficult to clean thoroughly, turning daily cleaning into a headache.
What exactly causes these annoying phenomena? From the characteristics of concrete itself, its internal porous structure makes it prone to generating dust and sand. During construction, if the process is not standardized—for example, improper concrete mix ratios, insufficient cement, or an excessively high water-cement ratio—it will lead to a loose concrete foundation and insufficient floor strength. After a period of use, the surface wears easily, exposing the concrete substrate and resulting in dusting and sanding. Moreover, construction dust falling on the ground also increases the likelihood of dusting.
Improper use and maintenance of the floor are also important factors. In industrial settings, floors bear heavy loads and mechanical friction for a long time, exceeding their load-bearing capacity, which gradually destroys the floor and causes dusting. If the floor is constantly in extreme wet or dry environments, moisture erosion during wet periods and shrinkage cracking during dry periods will exacerbate the problem. For instance, in some food processing workshops, floors are frequently washed with water, but poor drainage leads to long-term water accumulation. In some high-temperature workshops, moisture evaporates rapidly without timely moisturizing measures, accelerating floor damage.
Faced with such a tricky problem, is there an effective solution? While there are countless treatment methods on the market, BANDě Dust Preventer, as a liquid-penetrating inorganic material, has gradually come into view, bringing new hope to solving this problem.
Tracing the Source: Why Do Floors Dust and Sand?
(1) Material “Root Causes”
Cement, as the key binding material in concrete, directly determines the foundation of floor strength. Low-grade cement has relatively few active components. During the hydration reaction with water, it produces insufficient binding substances, making it difficult to tightly bond the sand and gravel aggregates. When subjected to external forces, such as pedestrian traffic or vehicle friction, the surface layer easily loosens and falls off, triggering dusting. It’s like using poor-quality glue to stick items; over time, they easily fall apart. In some small construction projects, substandard cement may be chosen to cut costs, laying hidden dangers for future floor problems.

Sand also plays an important role in concrete. Excessive mud content and overly fine particle sizes are detrimental to floor quality. High-mud sand has mud powder coating the sand grains, hindering the effective bonding between cement and sand, reducing overall strength. Mud powder also absorbs more water, causing an unstable water-cement ratio and further weakening the floor structure. Fine sand has a large specific surface area, requiring more water to coat the grains under the same cement volume. This increases the risk of a high water-cement ratio and reduces concrete density and wear resistance. In rural self-built homes, unfiltered river sand with high mud content is often used, easily causing dusting.
The water-cement ratio is a crucial factor affecting concrete performance. A ratio that is too high means excessive water. During hardening, excess water evaporates, leaving numerous pores that greatly weaken density and strength. Conversely, a ratio that is too low makes the concrete too dry to vibrate densely. On-site, workers randomly adding water for convenience is a common cause of water-cement ratio loss of control.
(2) Construction “Blunders”
Vibration is a critical step to remove internal air and densify the concrete. Insufficient vibration leaves internal voids, reducing strength like a sponge. If these voids concentrate on the surface, it leads to sanding. Over-vibration causes aggregates to sink and cement paste to float, creating a thick, uneven surface layer prone to cracking and sanding.

Over-vibration causes aggregates to sink and cement paste to float, creating a thick, uneven surface layer prone to cracking and sanding.
The timing of troweling is also vital. Troweling too early, during the initial setting stage, disrupts the microstructure and causes bleeding, reducing strength and wear resistance. Troweling too late, after final setting, makes it hard to achieve a smooth finish and may damage the formed structure. Rushed schedules often lead to inaccurate timing judgments.
Early-age freezing is a major taboo in concrete construction. In low temperatures, water freezes and expands. Ice crystals destroy the microstructure and reduce bonding force. Upon thawing, voids are left behind, making the structure loose and weak. Without proper insulation during winter construction, concrete is highly susceptible to frost damage.
(3) Post-Construction “Hardships”
Curing is essential for floor “growth.” Concrete needs sufficient moisture for hydration. If curing is neglected and moisture evaporates quickly, the reaction is incomplete, and strength fails to meet design requirements. Such floors are like underdeveloped children with weak resistance. Standards require 7-14 days of moist curing, but some contractors only cure for 1-2 days to rush schedules, severely damaging quality.

In industrial plants and warehouses, floors endure frequent rolling from heavy machinery and dragging friction. These forces exceed normal capacity, gradually wearing away the surface and exposing aggregates. Without effective protection, long-term exposure to UV rays, rain erosion, and chemical corrosion accelerates aging and dusting. For example, chemical plant floors in constant contact with corrosive substances suffer severe degradation.

Upon contact, active inorganic silicon dissolves in water, forming a highly reactive solution that easily penetrates pores and capillaries like tiny “engineers” reaching every corner.
During penetration, active inorganic silicon reacts with free ions to generate hard crystals. Highly stable and strong, these crystals act as “rebars” inside the concrete, tightly binding loose particles and greatly enhancing structural strength. They also fill internal pores, making the floor denser and effectively stopping dust generation. Special additives regulate the reaction speed and promote crystal growth, ensuring optimal performance under various concrete conditions.
(2) Deep Penetration and Strengthening Principle
The core of BANDě Dust Preventer’s ability to thoroughly solve dusting lies in its deep penetration and strengthening principle. Applied evenly, its small molecules utilize capillary action to penetrate 3-8 mm deep into the concrete, like water soaking into a sponge.

As it penetrates, active ingredients undergo complex reactions to form a 3D network structure inside the concrete. This highly strong and stable structure acts as a solid “skeleton,” tightly connecting aggregates and cement paste, significantly boosting overall strength. It also blocks the intrusion of moisture, air, and harmful substances, protecting the concrete from external erosion and achieving permanent hardening, wear resistance, dust prevention, and anti-seepage effects. Treated floors can reach a Mohs hardness of 7-8, with wear resistance multiplied several times compared to untreated floors, greatly extending their lifespan.
