Does the humid weather in spring affect the wall coverage?

Wall covering is about construction, and the seasonal influence is different. The influence of spring, summer and autumn on wall covering construction is basically the same. In these three seasons, the ambient temperature is high, the air mobility is good, and the construction wall itself is dry. After construction, the wall can easily absorb the moisture in the glue, making the glue easy to solidify and firmly adhere in a short time. Its characteristic is that the viscosity change, humidity and drying time of building glue will not have great influence on the construction quality. Even if cracks appear locally, the problem can be solved by repairing.

In winter, the environment in southern China, especially in coastal cities, is humid and cold, and the temperature difference between day and night is large. At this time, the surface of the newly completed building looks very dry, but in fact its water content is quite high. In this case, the water in the colloid is not easily absorbed by the wall, which leads to the colloid not solidifying for a long time, thus the adhesion fastness is poor. In addition, the temperature difference between morning and evening is large, which easily leads to the cracking of wall coverings (thermal expansion and cold contraction). The same problem is easy to occur in winter construction in northern China without heating.

Therefore, when covering the wall in winter, we should especially remind the coastal cities in the south and the areas with poor heating in the north, and we must pay attention to its viscosity and curing index in the process of purchasing glue. At this time, the glue listed in spring and summer can't be used temporarily because of its low viscosity and poor curing index. After use, it is easy to cause poor construction, and some glue with poor quality can't guarantee the construction quality.

To sum up, when supplying in winter, we should especially remind the southern coastal cities and the northern construction environment with poor heating (or no heating at all), pay attention to the problems that should be paid attention to in winter construction, and pay attention to whether the ambient temperature and the dryness of the wall during construction meet the requirements of the contractor, whether the purchased glue is suitable for winter construction and whether its curing index is higher than that in summer.
