Renovation process rejects dust hazard
In recent years, air quality has become a major concern for everyone. High PM2.5 levels have made people more aware of the importance of clean air for health. However, indoor dust pollution is often overlooked. Dust generated during home renovation can be just as harmful as outdoor pollution. It not only affects the health of workers and residents but also increases cleaning efforts. When dust accumulates, it can even pose risks to the entire renovation project. Controlling dust during construction is essential for maintaining a healthy environment and is a key indicator of the quality of the work.
**Protection Recommendations**
**Sealing the Floor to Prevent Dust**
One common source of dust comes from unfinished floors and walls after painting. This can lead to cracking, hollowing, or sanding, which contributes to dust pollution. For example, if a concrete floor has loose particles, it becomes difficult to clean and produces a lot of floating dust. This dust can stick to surfaces during later stages of construction, affecting the quality of putty and paint.
To address this, some renovation companies use a "ground solid" solution. This is a curing agent applied to cement floors early in the process. It penetrates the surface, sealing loose particles and helping decorative materials bond better with the floor. This reduces the risk of tile lifting and makes cleaning easier.
The cost of a barrel of ground curing agent ranges from 100 to 200 yuan, covering about 100 square meters. Consumers should check with their renovation company to see if this step is included in the project.
**Wet Cleaning for Dust Control**
Using water spray to control dust is an effective method during renovation. However, not all areas are suitable for wet cleaning. For instance, woodwork should avoid excessive moisture, as it can cause warping. Similarly, during the putty polishing stage, too much humidity can slow down wall drying and lead to dust settling quickly.
Ventilation is also crucial before moving into a new home. Along with vacuuming and wiping, placing wet wood chips on the floor can help absorb dust. The moisture prevents dust from becoming airborne, making cleanup easier.
In daily life, dust often accumulates under beds, windowsills, tables, and chandeliers. To reduce this, consider designing spaces that minimize hard-to-reach corners. Avoid overly complex ceiling designs and choose adjustable chandeliers for easier maintenance.
**Protective Measures During Putty Polishing**
During wall finishing, workers apply plaster and then putty. After the putty dries, it’s manually sanded with fine sandpaper, which creates a significant amount of dust. This dust can be harmful when inhaled over time.
To protect against this, both workers and homeowners should wear masks and other protective gear. Fine dust can settle on doors, windows, and other surfaces, so using a vacuum cleaner regularly is important.
Tip: In a 60-square-meter room, putty polishing typically takes one day. If you're doing partial renovations, plan ahead, protect your furniture, and limit your time indoors to reduce exposure.
**Dust-Free Cutting for Woodwork**
Wood cutting generates a lot of dust, especially when working with panels, ceilings, or flooring. These materials are often made from compressed fibers, which produce fine dust when cut.
Some companies now use dust-free cutters equipped with built-in dust collection systems. These tools significantly reduce airborne particles, improving air quality. When purchasing flooring, consider the quality of the installation to ensure minimal dust.
Tip: Always wear safety goggles and a mask when cutting wood. Ensure proper ventilation, and avoid outdoor cutting unless necessary. If possible, opt for custom furniture that can be installed directly indoors.
**Minimizing Dust from Bricklaying**
Bricklaying dust comes from cutting tiles, cement, and wall panels. These materials are made from clay and rock, and cutting them on-site can create a lot of fine dust. This is especially true when installing countertops or tiling walls.
To reduce this, designers should plan the layout in advance and have tiles cut off-site before installation. This minimizes on-site dust and ensures a cleaner workspace. During the process, try to concentrate cutting activities in one area and keep windows open for ventilation.
Tip: Fine dust can carry bacteria, so regular wet cleaning is essential, especially in air-conditioned rooms. Prompt cleanup helps prevent contamination and keeps the environment healthier.
