Inventorying four common types of poor quality building materials has encountered the right to defend the rights away from the trap

Why do we always face a variety of problems when we are decorating? Not all kinds of text traps were encountered during the signing of the contract. They were constantly deceived by unscrupulous construction teams during the renovation process. The purchase of building materials is even more frightening, and it is feared that if you spend a lot of money, you will buy defective goods. However, the construction of the entire home, all kinds of basic, and major materials are indispensable. Faced with so many poor quality building materials, the decoration people can not help but shout in their hearts: When will this type of deception come to an end?

Quality problems caused by various inferior building materials

1, metal wallpaper odor

"Why, when I buy wallpapers, I will feel a pungent smell when I open the wallpaper. I think it has a problem, but the seller said that as long as one sticks to the wall, it will be okay. This metal wallpaper is in the end. Safety? If it is really on the wall, when the volatile gas is still sucked in by us, it is certainly harmful to our health. In the end, what should we do?” Last week, Ms. Li sent such a help message at the forum.

After seeing the problem, Xiaoji interviewed some salespeople in the wallpaper industry. They said that the so-called metallic wallpaper is metal, gold, silver, copper, tin, aluminum, etc. Wallpaper surface. The commonly purchased metal wallpaper is called "gold foil." The price difference between the entire finished wallpaper market is relatively large, ranging from 20 yuan per square meter to over one thousand yuan per square meter.

In fact, what the sales staff said was made of gold, silver, copper and other heavy metal wallpapers were all made of paper. The electrolytic aluminum was made into a thin film by a special method, and the electrolytic aluminum was stuck to the paper with a binder. .

As Xiao Ji asked why he would be tempted by metal wallpapers, sales staff said that electrolytic aluminum itself is odorless, and the odor is caused because the base paper coating is a poor quality ink solvent.

2, waterproof material is not waterproof

Whenever it comes to the rainy season, there are always many owners who feel that their own homes are so easy that they have become “a sea of ​​oceans.” Before the renovation, they were all waterproof.

Compared to wires, pipes, floors, and other building materials, the quality of waterproof materials is considered by some people as "small problems." However, the fact is that the waterproofing of the roof is an important project of the house construction. The leakage of the roof will directly affect the function and life of the building. Recently, the incidents of “building” and “crushing and brittle” which were exposed by the media have all been related to the waterproof quality of buildings.

Although there are quite a few national standards concerning waterproof materials, the actual implementation of the standards is not in place. Some inferior products have changed a new name, and they enter the market in a grandiose manner to squeeze qualified products from regular manufacturers at low prices. Construction workers do not understand the process, blind construction is also an important factor affecting the waterproof effect. When heavy rain or heavy rain comes, joints are particularly vulnerable to water seepage, and the treatment of local leaks is often more troublesome than new construction, so leaks have become difficult to cure the "diarrhea."
