    Construction of architectural coatings is very simple, with rich and soft colors, smooth and clear lines, creating multiple texture effects, easy to repair and change. But the sky has unpredictable clouds, if the construction process does not pay attention to the weather, will affect the quality of the coating, the exterior wall beautiful, the next for everyone to tell you about the temperature, wind, rain and other external wall construction impact.
    1, the impact of
    (1) Do not work before and after the temperature of 5 degrees Celsius and before and after
    the
    .
    (2) morning and evening and noon temperature difference is too large, as well as the night cold through the surface, to noon also did not warm the wall can not be constructed, otherwise it will cause poor dense, so need to pay full attention.
    (3) cannot be constructed on the substation of the accumulated water.
    2, the impact of the wind
    high winds will accelerate the evaporation process of solvents or moisture, so that the film is bad, but also stained with dust, clear weather conditions are very important for the coating project, poor coating conditions will make the coating project greatly discounted. When wind speeds above 5m/min, work should be stopped, especially in low winter temperatures. Because of the wind, the temperature of the wall surface will drop lower than the temperature, in order to avoid the impact of the wind, should pay attention to cover the pomp.
    3, the impact of
    coating materials if not completely dry when the rain, the paint will be washed away. Not only should the construction pay attention to the meteorological situation, even after the construction should pay attention to the meteorological situation. If it rains before construction, there is moisture left in the substation, so that the water content becomes higher, it can not be forced to construct. Before it rains, the foundation part of the daily construction will be covered with a poncho cloth, can not be mistaken for continuous construction. Absolutely can not be in the water content exceeds the prescribed standard of the substation construction, not in accordance with the operating procedures of the construction, will cause film peeling.
    4, the effect of
    even if the day is sunny, the evening will dew, to the morning on the surface of the substation there is a layer of dew. Forced construction at this time, will cause the coating film and the substation of poor tightness, should wait for the substation to completely dry before entering the construction.
    5, humidity
    high humidity day construction, drying speed will slow down, should pay attention to ventilation. Construction should be stopped when the humidity exceeds 30%, due to meteorological conditions caused by poor construction results concentrated in winter, should pay special attention to the local weather conditions at that time.
