The problems, causes and countermeasures of the six types of building materials

Building materials products are an indispensable part of home decoration. Tiles, wooden floors, and interior wall paints are mostly semi-finished materials. They require paving and brushing to be used for decoration and use. However, in the process of paving and brushing, due to the quality of the material itself and technical problems during paving, foaming, cracking, etc. occur in the later use of the material, causing consumer complaints. Here, the reporter gave a detailed analysis of the problems, causes and countermeasures of the six types of decorative materials that are prone to occur.

wooden floor

The focus of complaints is that the color difference is large and uneven, and the gap increases after one year of use.

Analysis of the reasons: solid wood flooring production suppliers tend to be out of stock because of a certain wood species out of stock and cause the goods not board, at the same time, because solid wood flooring is taken from natural scarce wood, texture and color will have a larger color, so The difference in overall effect after paving is even more pronounced. In addition, wood flooring is not only important for materials, but also important for installation. Blisters, cracking, etc. occur later in the use of flooring. Generally, it is caused by the decoration of another decoration team that is inexperienced. At this time, the determination of responsibility is relatively difficult. Under the circumstances, consumers can only suffer from a loss.

Consumer tips: When buying, try to find a dealer who is approved by a regular brand or buy it from a well-known building materials supermarket. When the goods arrive at home, it is best to unpack, inspect each wooden floor, or check the wooden floor, and identify problems in time for return processing.

In terms of construction, we must ensure that the construction team has sufficient experience and fully understand the characteristics of the wooden floor varieties purchased. If you want to insure some, it is recommended that consumers hire professional workers provided by wood flooring manufacturers to install the door. These professional workers are more familiar with the brand of wood flooring, laying is also relatively formal.

Interior wall paint

The focus of complaints: Washability is not enough, easy to arch foaming peeling.

Analysis of causes: Scrub resistance refers to the relative abrasion resistance of the paint coating when it is repeatedly scrubbed to remove contaminants during use. Construction coatings used in workplaces and places of life, especially those near doors and windows, are often easily soiled, which requires frequent scrubbing, so scrub resistance is an important indicator of interior wall paint, but some interior wall paints The washability of the material is notoriously different from the publicity materials.

Consumer tips: When you purchase interior wall paint, you should first determine the requirements for product performance, decorative effect, and price, and then try to buy products of well-known companies or brands. When purchasing interior wall paints, attention should be paid to the production date and shelf life of the products. The effective storage period of synthetic resin emulsion interior wall paints is generally one year.

When you buy, you can open the lid and observe that the qualified interior wall coating should be delicate and uniform. There should be no settlement, agglomeration, floating water, mildew, and odor.

Pay attention to the following items on the packaging barrel: product model, specification grade, name, batch number, standard number, weight, manufacturer, and production date. Products that do not have the above explicit content should be purchased with caution.

Doors and windows

The focus of complaints: The strength of frameless balcony windows is not enough, the variable type, and the wind pressure rating is unqualified.

Analysis of the reasons: Doors and windows not only bear environmental impacts such as storms, rain, and snow, but also have to withstand the gravity of the switches and deadweight in use. The three physical properties of frameless balcony windows, namely wind pressure resistance performance, air permeability performance, and rain leakage performance, have gradually become one of the focuses of quality control in construction projects. The safety of doors and windows depends mainly on its ability to withstand wind power, which is usually measured by the pressure of the gas on a unit area. In practical application and testing, the quality of frameless balcony windows does not meet the requirements of the relevant national standards.

Consumer tips: Before material selection, load calculation should be based on the external window structure specifications. Standard profiles should be used as much as possible. The wall thickness of the profile should be determined according to the section characteristics of the profile. The wall thickness of the aluminum alloy profile should be based on the measured data of the entry material. Only look at the nominal wall thickness, and the measured wall thickness of the force members should not be less than 1.2mm.

Sanitary ware

Complaints focus: The price difference is large, and after-sales service is missing or delayed.

Sanitary products are surprisingly high, and they are often sold at a discount of as low as 50% or less. This is most often seen in the traditional building materials market. Once the sanitary ware product has a problem, the after-sales service promised by the manufacturer when the consumer purchases is difficult to achieve.

Analysis of the reasons: The bargain sale method is the most serious in the field of sanitary ware. Dealers generally do not clearly price, often claiming to give consumers discounts, and some consumers are greedy for cheap and buy sanitary ware in such businesses, and finally fell into the price trap of the business. In addition, low prices also mean that after-sales service has shrunk. Consumers may encounter complaints about product problems in the future.

Consumer tips: Consumers should understand that low-cost sales and discounts are just a common trick for businesses to attract consumers' attention. Consumers should go to regular stores or building materials supermarkets to buy products. Do not sacrifice the cost of after-sales service for the sake of cost. . When purchasing, consumers should look at the purchase contract and the post-sales service promised by the manufacturer, and confirm the content of the service. It is best to contact the manufacturer department directly after the sale to determine if problems can be solved in the future. Then buy the sanitary ware product.

cupboard

The focus of complaints: cut corners, more area.

Analysis of reasons: Due to the fierce competition in the cabinet industry, some manufacturers cut corners in the production process for the purpose of profit-making, or use counterfeit and inferior materials to replace, making it difficult for cabinets to meet the national environmental standards.

Excessive aldehyde content, scratch resistance, resistance to dry heat, and other substandard performances are still hot topics for cabinet complaints. Because many consumers do not understand the calculations, some informal cabinet brands use this loophole and calculate the area to make consumers pay more.

Consumer tips: At the time of purchase, besides recommending purchases to regular big brand cabinet makers, do not listen to the sales person's side words. It is best to check the relevant environmental quality certification. It should be noted that all rows of boreholes on the cabinet panels are best fitted with caps, which can effectively reduce the release of formaldehyde and be more environmentally friendly and safe.

In terms of pricing, consumers must not blindly look at prices to make decisions, do not calculate them in general, and it is best to classify cabinets according to their actual use, and deduct any space that does not require the use of plates. The price list of cabinets should be as detailed as possible.

ceramic tile

The focus of complaints is: Low water absorption, easy to slip, yellowing and darkening in less than a month.

The complaints about the quality of the tiles in the living room and the tiles on the wall are most concentrated, including uneven surface or joints, water slippery on the ground in the morning and evening, etc.; and the bathroom wall tiles are yellowed within a month and the surface produces black spots. Even cracks occur at the joints of the tiles.

Analysis of the reasons: The quality of the tiles is usually seen from the appearance. If there are black spots or pinholes, the salesperson will deceive consumers to say that this is a special effect of color. In fact, this is the tile appeared in the calcination process. Quality issues. In addition, there may be scratches, cracks, etc. on the surface of the tiles, which may be caused by collisions during transportation. Tiles are also semi-finished materials. The yellowing and blackening of pavements generally occurs in tiles, kitchens and other areas where the moisture and moisture are heavy. There are two reasons: First, the tile itself has a high water absorption rate; the second is the collage. When the tile is not tight, it results.

Consumer Tips: There are many ways to identify the quality of tiles, which can be identified by listening, watching, and touching. First, tapping on the surface of the tile sounds crisply indicating the density and hardness of the tiles. Secondly, look at the glossiness and flatness of the surface of the tile. You can use a hard object to scrape the tile surface. If you leave a mark, it indicates that the tile is glazed. Finally, you can feel the quality of the tiles by touching them and see if the surface of the tiles is uneven.

In addition, according to the wear resistance of tiles, water absorption, etc., to assess the tiles suitable for laying in which areas. When receiving the goods, it is necessary to clearly see whether the outer packaging of the tiles is in good condition and whether to open the inspection tiles to see if they are cracked. The broken tiles can be returned promptly by the manufacturer.
