What is the reason for the wall sweating? Gypsum board system solves hidden dangers

In winter and early spring, there is a phenomenon in the south where if windows are not opened for a long time to ventilate, water stains will inexplicably appear on the walls, making them look like they are sweating. Especially in the Jiangsu, Zhejiang, and Shanghai free postal areas, this phenomenon is even more obvious. If residents with lower floors experience this situation for a long time, it can even cause mold on the walls, which is very headache inducing. Why does this phenomenon occur, and what are the better ways to solve hidden dangers? Let's listen to Jason's gypsum board editor.


First of all, let's talk about the reason. In fact, this situation ultimately boils down to a significant difference in indoor and outdoor temperatures, combined with the condensation caused by high humidity. So this natural phenomenon is relatively rare in the north, and it is also rare in the southern regions of Guangdong, Guangxi, and Fujian where the winter and spring temperatures are not low. Only in Jiangsu, Zhejiang, and Shanghai is it very common, especially when hot air conditioning and humidifiers are turned on at home, without opening windows for ventilation, it is easy to form such a situation. If this situation occurs, it is okay for residents in higher floors, but it is very unfriendly for residents on lower floors or even the first floor. Therefore, friends from Jiangsu, Zhejiang, and Shanghai often talk about mold prevention issues.


Furthermore, if this condition persists for a long time, it can cause mold spots on the wall, cracking and peeling of the latex paint wall, and the putty layer will also become moldy. This not only produces an unpleasant musty smell but also poses a threat to human health. A friend would say, "Can't I just shovel the wall and repaint it?" This can be acceptable, but it's just a temporary solution. Living for two or three years can still make a comeback, which is also the reason why many families cannot bear to have to renovate as a whole. So how can we cure it?


Simply put, reducing humidity to maintain ventilation is essential, but it is indeed difficult to achieve in winter and early spring. Therefore, it is necessary to add a fresh air system to the decoration design, so that it can achieve the ventilation effect of air exchange without the need for windows. Simultaneously installing underfloor heating, especially water heating, is better than using a humidifier while turning on a hot air conditioner, even for wall heating, to avoid drying and catching fire caused by heating. Even in the rainy season, dehumidifiers need to be used to keep the room dry.


In addition to supporting equipment, the best way to avoid wall problems is to start from the wall decoration itself, which is the field where gypsum board systems can showcase their skills. The most practical ways to solve similar problems are twofold: firstly, to use the veneer wall system in all aspects; secondly, to use fiberglass faced gypsum board instead of ordinary paper faced gypsum board in the covering material of the veneer wall system. The combination of these two measures can produce a follow-up effect of 1+1>2, truly solving the problems of mold, cracking, and bulging of the wall caused by moisture regain.


Veneer wall system is a partition wall system that uses metal U-clips to fix light steel keel and then installs gypsum board on the surface (as shown in the above figure). Compared with traditional gypsum board partition systems, its biggest advantage is that it occupies an extremely limited thickness, with the gypsum board itself having a maximum thickness of only 3CM, so there is no need to worry about using gypsum board partitions to occupy the usable area of the house. If the veneer wall system is installed at the same time, there is no need to do any treatment to the original wall surface, and it can be installed directly; It eliminates the need for slotting and laying strong and weak electrical conduits on the original wall surface, as well as the process of finding equality. Simply laying conduits in the veneer wall system is sufficient, which can be said to be very time-saving, labor-saving, and labor-saving. In this way, after the construction is completed, there is a gap between the finished surface and the original wall surface. Coupled with the breathing performance of the gypsum board itself, it can effectively avoid the situation where moisture cannot dissipate for a long time and produce mold.


Fiberglass surface gypsum board, developed independently by Jason, is a high-performance fiberglass surface gypsum board. Not only does it have the characteristics of environmental protection, lightweight, fire resistance, and easy construction that gypsum board materials themselves possess, but it also effectively improves and strengthens the strength and nail holding performance of gypsum board itself, allowing Uber special board to perfectly replace traditional wooden base board as the base board for woodworking construction nodes. As the covering material for the overall veneer wall system, the installation of octagonal box switch panel and wall decoration such as wall lamp hanging and painting on the finished surface are also fully applicable. At the same time, it solves many hidden dangers such as non fire resistance, environmental protection issues, and susceptibility to moisture deformation and cracking of traditional wooden base boards, achieving a one-time and permanent completion and use effect. The most important point is that compared to ordinary paper faced gypsum board, this inorganic fiber surface layer material is less susceptible to moisture and mold growth. In addition, if there is no need for wall decoration, using Jason water-resistant paper surface gypsum board and Jason moisture resistant paper surface gypsum board with special treatment of protective paper will achieve better water and mold resistance.


As a high-end gypsum board system solution provider, Jason gypsum board continuously conducts market research, formulates research and development directions based on actual project usage and user feedback, and further develops more new products and systems that can effectively solve the actual problems of end users. Technology changes life, and Jason Company is tirelessly striving to provide more gypsum board system solutions for its users.
