1、 Air drying time the air after rain is very humid and the water vapor content is very high.
Since spring, most parts of China have more rain, especially in southerly days in the south, with heavy moisture.
4、 Generally speaking, the construction can be carried out only when the wall temperature is above 5 ℃, the air relative humidity is not greater than 80%, and the wall humidity is less than 10%.
3、 The normal drying time of the wall is about two hours, but in case of rain or haze, it shall be extended according to the weather conditions, and the construction shall be carried out after the wall is completely dry.
In rainy weather or haze, the humidity in the air is relatively high, and the wall is wetted by rain.
If these base course treatments are not done well, there will be bulges, cracks and other problems soon after spraying the finish paint in the future.
Therefore, when doing air drying works on the wall, the air drying time on rainy days should be two times more than the usual air drying time.
2、 The putty and wall lining of the base course of the wall surface need to be dried for a day in rainy days.
The weather will have an important impact on the construction effect of exterior wall real stone paint.
It must not be calculated according to the usual air drying time.
Too high moisture content will lead to drum, alkali return and other disadvantages…
In order not to affect the construction effect and quality of exterior wall real stone paint, the following four points must be known in case of rainy days during construction.
