[Summary]1. Due to the wide application of glue-free gypsum on the market, there are the following hidden dangers

1.1 This type of product has poor leveling ability in full batches. The wall after glue-free gypsum treatment needs to be filled with thicker or even extra-thick putty during construction, which exceeds that of the putty paste, which is less than 0.5mm per batch, and the total thickness is less than 2mm. requirements (see each product manual).

1.2 This type of product solidifies quickly, but it is not easy to dry. Often, the glue-free gypsum used for wall construction is solidified but not completely dry, and the workers will scrape the putty paste, causing the putty paste to be scraped on the wall or scraped and turned over.

1.3 Even if the glue-free gypsum has dried up, due to its extremely poor water resistance, it is not easy to dry after absorbing water. During the construction of the putty paste, the glue-free gypsum absorbs a large amount of water in the putty paste and returns to a water-retaining, moist and soft state. The surface is subjected to external force by scraping. Friction damage, causing the putty paste to be unable to apply to the wall or scrape the skin.

1.4 Due to the strong water absorption and water retention of glue-free gypsum, the putty paste should be dried first after being scraped, but the bottom glue-free gypsum is not dry. In this way, the surface layer of putty paste will crack, peel, and fall off, especially in the thick scraped part of the putty paste. Good quality putty paste has high tension and high hardness and is more likely to crack.

1.5 The bottom layer of glue-free plaster is not dry enough or absorbs water and returns moisture, and it will also cause mold on the wall, which will seriously affect the decorative effect and human health.

2. Technical personnel must pay attention to the following matters when dealing with quality complaints

2.1 Check the condition of the base layer of the wall (the condition of the original base layer, what kind of putty is used, whether the base layer is treated according to the requirements of the product manual, the dryness of the base layer, and the flatness).

2.2 What is the thickness of the wall scraping company's putty paste?

2.3 The cracked part of the putty paste and how much it cracked.

2.4 Analyze the causes of wall problems and identify responsibilities.

2.5 The treatment plan must have a treatment method for the grassroots, and must include the following:

2.5.1 For the glue-free gypsum wall or the wall behind the shovel wall, the interface agent should be brushed after the wall is dry, and the interface agent must be brushed;

2.5.2 The uneven wall and top should be smoothed and dried before the putty paste should be scraped, and the construction should be carried out in strict accordance with the thickness and method required by the product instruction manual;

2.5.3 The interface agent is fully brushed 2-3 times, and then the putty paste is scraped off the closed wall after drying;

2.5.4 For the glue-free gypsum wall, it is best to persuade the customer to completely remove the glue-free gypsum layer, and use the blue star corundum two-component corner fillet with good water resistance and fast drying to repair the uneven base surface or straighten the yin and yang corners to No aftermath.

2.6 Summarize the process and completion of resolving complaints this time, so that you can better deal with similar situations next time. Report the company's product quality problems or various factors that are likely to cause product quality problems to the company in a timely manner to ensure that similar problems can be avoided next time.
