Renovation process rejects dust hazard
Air quality has become a major concern for everyone in recent years. High PM2.5 levels have made people more aware of the importance of clean air for health. However, dust and smog are not only outdoor issues — they can also be generated during home decoration. Indoor dust spreads easily, posing health risks to workers and residents, while increasing cleaning efforts. In severe cases, it can even create hidden dangers for the entire renovation project. Controlling dust during the process is not just about keeping the environment clean; it’s also an essential indicator of the quality of the work.
**Protection Recommendations**
**Sealing the Ground to Prevent Dust**
In many new homes, the ground and walls aren’t fully prepared before painting, which can lead to hollowing, cracking, or sanding — all sources of dust. For example, if a concrete floor has running sand, it becomes loose and hard to clean, causing floating dust that pollutes the environment. This dust can stick to surfaces during later construction, reducing the quality of putty and paint.
To address this, some renovation companies offer a "Ground Solid" program. This involves using a ground curing agent to seal the cement floor early on. It penetrates the surface, blocking loose particles and ensuring better adhesion between the flooring and decorative materials. This helps prevent tile hollowing and makes cleaning easier. A barrel of curing agent typically costs between 100–200 yuan and can cover around 100 square meters. Consumers should check with their contractors to see if this is included in the project.
**Wet Cleaning to Reduce Dust**
Water misting is an effective way to control dust during renovation. However, not all areas are suitable for this method. For instance, when working with wood, excessive moisture can cause warping. Similarly, during wall putty polishing, too much humidity can slow down drying and make dust settle quickly.
Ventilation is crucial before moving into a newly renovated home. In addition to vacuuming and wiping, placing wet wood chips on the floor can help absorb dust. These chips have an adsorption effect, preventing dust from becoming airborne when water is sprayed. This makes cleanup more efficient.
In daily life, dust often accumulates under beds, windowsills, tables, and chandeliers. To reduce this, try to avoid designing spaces with hard-to-reach corners. Keep ceiling designs simple and choose chandeliers that are easy to reach for regular cleaning.
**Protective Measures During Putty Polishing**
During wall decoration, workers first apply plaster to level the surface, then use putty powder. Once dry, they manually polish the area with fine sandpaper. This process generates a lot of dust, which can be harmful if inhaled over time.
To protect against this, both workers and residents should wear masks and other protective gear. Fine dust can settle on doors, windows, and furniture, so regular vacuuming is important. Tip: For a 60-square-meter room, putty polishing usually takes about a day. If you're doing partial renovations, plan ahead, protect your furniture, and limit your time indoors to minimize exposure.
**Dust-Free Cutting for Woodwork**
Wood cutting generates a significant amount of dust, especially when working with panels. These panels are made from processed materials, and cutting them can release fine particles. Floor installation also produces dust, which is hard to remove completely and may pose long-term health risks.
To reduce this, some companies now use dust-free cutters. These tools are designed to minimize dust generation and often include built-in dust collection systems. When choosing flooring, consider the quality of the installation. Tip: Always wear safety goggles, a mask, and ensure good ventilation when cutting wood. If possible, opt for custom furniture that can be installed directly without on-site cutting.
**Minimizing Dust from Tiling Work**
Bricklaying and tiling also produce a lot of dust, especially when cutting tiles on-site. Clay and rock-based tiles are often cut during installation, creating a lot of fine particles. This is particularly common when installing marble countertops or wall tiles.
The best solution is to have tiles pre-cut at the factory and installed on-site. This reduces on-site dust and pollution. During the process, try to concentrate cutting in one room and keep windows open for proper ventilation.
Tip: Fine dust can carry bacteria, so it's important to clean regularly, especially in air-conditioned rooms. Use wet cleaning methods to avoid spreading contaminants.
