One, Does seamless wallpaper contain formaldehyde?

Seamless wall coverings are developed based on fabric, which is a textile material. It is common to see various construction materials advertised with "0 formaldehyde" claims in various promotional materials. Is this claim truly accurate? Seamless wall coverings for home use consist of two parts: seamless wall covering and accessories (hot melt adhesive is a thermoplastic adhesive, and cold melt adhesive is made from rice glue, plant-based glue, etc.). If seamless wall coverings for home use are free of formaldehyde, then both the seamless wall covering and the accessories must be free of formaldehyde.

1. First, whether the seamless wall covering contains formaldehyde.

The raw materials of the fabric, such as fibers, silk, and cotton, are natural materials without chemical components. Fabric is a textile product, and the wide range of colors in seamless wall coverings is due to a dyeing process in between. This dyeing process is used to achieve the desired colors and ensure long-lasting colorfastness. Dyes are generally divided into natural dyes and synthetic dyes. Some synthetic dyes can contain formaldehyde.

Additionally, in textile production, to enhance wrinkle resistance, water resistance, and fire resistance, formaldehyde-containing additives are often added. This results in the release of formaldehyde from the products during use.

Therefore, the claim that seamless wallpaper has zero formaldehyde is not scientifically accurate. In reality, the formaldehyde content of seamless wallpaper is within a safe range, and its impact is minimal.

2. Second, auxiliary materials for seamless wall coverings.

The wall covering needs to be adhered to the wall, and the adhesive typically contains formaldehyde. Adhesives are primarily divided into two types: organic solvent-based and water-based. Organic solvent-based adhesives not only contain formaldehyde but also often contain other organic volatile substances such as toluene and xylene. The formaldehyde content of the additives has a significant impact, and this is the key factor to consider.

Two. The strong odor after applying wallpaper is due to what?

1、Using substandard glue for pasting wallpaper will release a certain odor. The substandard glue is of poor quality and emits a strong odor, and it also contains many harmful chemicals, which can cause unpleasant odors in the room even after the wallpaper is pasted.

2. Some low-quality wallpapers may have a certain odor during the manufacturing process.

Three. How to deal with the strong odor of wallpaper.

1、Utilize plants to purify the environment.

You can place green plants such as spider plants, aloe vera, and cacti indoors. To quickly eliminate the unpleasant odor from the wall coverings, you can expose the plants to light. When exposed to light, the plants become particularly vibrant and their photosynthesis increases, releasing more than double the oxygen compared to plants in darkness.

2. Maintain ventilation in the room.

After applying the wallpaper, open the windows to maintain good ventilation and allow volatile substances like formaldehyde in the building materials to dissipate. However, it is important to note that to prevent the wallpaper from curling at the edges, allow the wallpaper to air dry for 5-7 days before opening the windows for ventilation.

3、Utilize healthy and energy-efficient air purification lamps

Air-purifying lights can instantly eliminate indoor smoke and toxins, remove various odors and smells, and also kill various bacteria in the air, preventing and reducing the spread of mold and allergens.

4、Activated carbon

Purchase a block of black activated carbon from the store. Although it may not be aesthetically pleasing, it effectively absorbs formaldehyde. After use, simply place it in direct sunlight to dry and reuse.

5、Rework

If the odor persists for a long time after wallpaper installation, it indicates either a problem with the wallpaper quality or the adhesive used. In this case, the only option is to contact the original contractor to redo the installation.
