If the construction is not carried out according to the operating procedures, the film will peel off.
5.
If the coated material gets wet when it is not completely dry, the coating will be washed away.
② The temperature difference between morning and evening and noon is too large, and the surface is cold at night, and the wall surface that is not warm at noon cannot be constructed, otherwise it will cause poor adhesion, so full attention shall be paid.
The construction shall be carried out after the base surface is completely dry.
③ Construction cannot be carried out on the foundation surface with accumulated water.
Influence of humidity.
However, the weather is unpredictable.
4.
2.
Influence of wind.
In the morning, there is a layer of dew on the surface of the base surface.
When the wind speed reaches more than 5m / min, the construction shall be stopped, especially when the air temperature is low in winter.
3.
Next, Guoli water paint will tell you about the impact of temperature, wind and rain on the outer wall construction.
In order to avoid the impact of the wind, pay attention to covering the tarpaulin.
Strong wind will accelerate the evaporation process of solvent or water, resulting in poor film formation and dust contamination.
Before rain, cover the foundation surface to be constructed every day with tarpaulin, so that continuous construction can be carried out without mistake.
Sunny weather conditions are very important to the coating project, and bad coating conditions will greatly discount the coating project.
It is absolutely forbidden to construct on the base surface with moisture content exceeding the specified standard.
The construction of architectural coatings is very simple, with rich and soft colors, smooth and clear lines, can create multiple texture effects, and is easy to repair and change.
When the humidity exceeds 30%, the construction shall be stopped.
When construction is carried out on days with high humidity, the drying speed will slow down, so pay attention to ventilation.
The poor construction effect caused by meteorological conditions is concentrated in winter, and special attention shall be paid to the local meteorological conditions at that time…
Due to the wind, the temperature of the wall will drop lower than the temperature.
The influence of rain.
If you don’t pay attention to the weather during the construction, it will affect the coating quality and the appearance of the outer wall.
Forced construction at this time will cause poor adhesion between the coating film and the base surface.
Pay attention not only to the meteorological conditions during construction, but also after construction.
Impact of temperature, wind and rain on exterior wall construction 1 Influence of air temperature ① do not construct below 5 ℃ and before and after rain.
Influence of dewing even if it is sunny during the day, dewing will occur at night.
Before construction, if it rains and there is water in the foundation surface, so that the water content becomes higher, forced construction is not allowed.
