How to choose environmentally friendly wallpaper adhesive? Choose wisely to avoid pitfalls!

When it comes to decorating new homes or renovating old ones, wallpaper stands out as a preferred choice for wall decoration due to its high "appearance value", diverse styles, and strong atmosphere. However, most people only focus on the color and material of wallpaper, neglecting the importance of wallpaper adhesive. As the saying goes, "wallpaper accounts for 30% and adhesive accounts for 70%." Adhesive not only determines the firmness and flatness of the installation, but also directly affects indoor air quality. Poor-quality adhesive may contain excessive formaldehyde and have a pungent odor, posing a risk to family health if exposed for a long time.
With a wide variety of wallpaper adhesives on the market and varying prices, ordinary consumers are easily tricked by merchants. It's easy to accidentally buy products that are not environmentally friendly, prone to mold growth, or prone to adhesive failure. Today, I will provide you with a professional and reliable guide for purchasing wallpaper adhesives, teaching you to easily avoid industry traps and choose healthy, environmentally friendly, durable, and worry-free wallpaper adhesives.

 

 

First, identify the category! Different wallpaper adhesives have significantly different environmental protection levels
When purchasing wallpaper adhesive, it is important to distinguish between mainstream categories. Adhesives made from different raw materials vary greatly in terms of environmental friendliness, viscosity, and applicable scenarios.
1. Glutinous rice glue
Currently, the mainstream eco-friendly wallpaper adhesive recommended for home decoration is made from natural glutinous rice starch, free of formaldehyde, benzene, and heavy metals. It is purely natural and biodegradable, ready to use after mixing with water, and has a light odor with almost no off-flavor. With moderate viscosity and good permeability, it is suitable for most household wallpapers such as non-woven wallpaper, pure paper wallpaper, and PVC wallpaper. Its superior moisture and mold resistance makes it a good choice for families who prioritize environmental protection.
2. Vegetable gum
Using plant starches such as corn and potato as raw materials, its environmental protection level is second only to glutinous rice glue. It is safe and non-irritating, with a high cost-performance ratio. The viscosity is stable, making it suitable for ordinary home wallpaper installation. However, its anti-mildew effect is slightly inferior to glutinous rice glue in humid environments.
3. Barreled industrial adhesive
Most of them are chemically synthesized adhesives, which are inexpensive but prone to exceeding formaldehyde and VOC content standards, emitting strong pungent odors. Although they have strong adhesion and dry quickly, they release harmful gases over a long period of time and are prone to issues such as mold growth on walls and warping and cracking of wallpaper. It is strongly advised against their use in home decoration, and they are mostly only used for temporary decoration in industrial settings.
4. Rubber powder + rubber paste combination
Traditional old-fashioned combinations often use starch-based glue powder, and the glue paste contains chemical additives. Some low-end products fail to meet environmental standards, are prone to bacterial growth and mold development, and are now gradually being replaced by glutinous rice glue.

II. Keep a close eye on environmental indicators and steer clear of areas with high formaldehyde levels
To determine whether wallpaper glue is environmentally friendly, there are several hard criteria to look for, rather than relying on verbal boasts from merchants. First, check the testing and certification. Formal environmentally friendly wallpaper glue should have relevant environmental testing reports for building materials, and possess certifications such as the China Environmental Labeling Product Certification and Green Building Materials Certification. Such products are produced to strict standards, with harmful substance content meeting relevant requirements. Next, examine the ingredient list. High-quality environmentally friendly wallpaper glue only contains basic raw materials such as natural starch and purified water, without chemical additives such as formaldehyde, benzene, plasticizers, or industrial preservatives. Any product with an unclear ingredient list or that is hesitant to disclose its components should be avoided. Additionally, simple on-site identification can be made. High-quality environmentally friendly wallpaper glue only emits a faint starch fragrance upon opening, without pungent or irritating odors; whereas inferior glue emits a strong chemical or sour smell upon opening, which is difficult to dissipate even with ventilation, and should not be purchased.
