Many people in summer think that it is not a good season for decoration, especially for interior wall decoration. There are many unfavorable factors. In fact, we only pay attention to some key aspects of the wall decoration to prevent some quality problems. In this case, the summer wall decoration is not a problem. Here are just a few examples of what we need to pay special attention to.

Wall thermal expansion and contraction, wall cracking skin
In the hot and humid summer months, not only is there a hidden danger in the construction of the wall, many potential wall problems will also appear at this time. Due to the large indoor and outdoor temperature difference in Beijing in the summer, the use of air conditioning in the room causes thermal expansion and contraction of the wall, and cracking and peeling of the wall will occur.
The summer rainy season is accompanied by wind, so that the rain always falls in the same position on the outer wall. It can't dry for a long time. If the weather is not clear in 3-4 days, it is very likely to leave a “watermark†on the wall. At the same time, during the rainy weather in summer, the terraces and the walls on which the rainwater pipelines are distributed, and the water vapor lingers for a long time may also lead to maladies such as “mold spotsâ€. In addition, for areas where the moisture is relatively heavy, such as kitchens and bathrooms, in the summer when the air has a very high moisture content, the tiled walls are prone to “condensingâ€. If the ventilation is not good for a long time, it may even leak into the room. The surface of the interior wall is such that there is a phenomenon of exfoliation or peeling on the wall surface.
To prevent and treat seasonal "diseases" in the summer wall, the selection and construction of the substrate putty is more important than the surface latex paint. Because some irregular decoration teams use inferior putty, they are easily dissolved by water and their strength is low. They are exposed to seasonal changes such as temperature and humidity. Therefore, when signing a decoration contract, the industry pays attention to the warranty period. In addition, the remaining putty and other painting materials should not be discarded, leaving part of them for testing when problems arise.
Wall construction should eliminate "dry"
Although the materials and processes for wall painting are very mature today, some problems may arise due to seasonal features when choosing to construct in the summer. Due to the hot and hot weather in summer, when visual observations and feels are used by construction workers to judge whether the basement is dry or not, there may be an illusion that the wall has dried out. In this case, applying a wall paint will likely lock in moisture, causing the wall to become chalky, blistering, discolored walls, and even cracking over time.
Although the construction in summer is fast and dry, the air humidity is much larger than that of other seasons, which has a great impact on the construction of the wall. He said that although the summer wall putty layer will quickly dry, but in fact it is only the "dry surface" phenomenon under hot weather.
For the wall projects that are vulnerable to the effects of moist air, relevant industry sources have made some suggestions. They pointed out that the wall putty or putty on the ceiling is difficult to dry in the wet season in summer, so it is best to put the putty on top of the paint for longer intervals, or try to build on a sunny day.
If the interface treatment of the wall construction is not done well, the phenomenon of "return alkali" of the original structural wall material is likely to occur in the summer, leaving white or yellow stains on the wall surface. In addition, waterproof putty should be used for wall treatment, so that the bond between the paint and the base layer is stronger and less likely to fall off, so as to avoid yellowing of the wall due to the summer humidity and prevent the wall from cracking over time.
