The rainy season in spring really stone paint construction should pay attention to what issues?

Spring is a rainy season, especially in the south, where the south, the humidity is very large. The weather is important factor affecting the effects of outer wall really stone paint construction. Therefore, in order to not affect wall really stone paint decorative effect and stable quality, in the rain for exterior wall really stone paint construction must pay attention to these matters. Next, to edit KeBao building materials to share with you the spring rains really stone paint construction matters needing attention. 1. Drying time: after the rain the air is very humid, water content is very high. As a result, air drying on the walls, a rainy day 1 - air drying time should be longer than usual 2 times, must not be calculated at normal air drying time. 2. Basic level processing: metope grassroots putty and metope lining need air basks in one day in rainy day. If these improper handling at the grassroots level in the future after spraying paint crack problem of inflation and will appear soon. 3. Drying time: the wall normal drying time is about two hours, but in case of rain or fog, should according to the weather condition to extend the time of construction, the wall should be completely dry before construction. 4. Deferred construction: in general, only when the wall temperature is above 5 ℃, air relative humidity is not more than 80%, the wall when humidity is less than 10% to the construction. On a rainy day or of the smoke, relatively high humidity in the air, the wall is soaked by rain. Such as high water content can lead to bulge, alkali return defects. On a rainy day, a small piece or more small pieces is very different from other parts of the light color or white area will appear on the metope with really stone paint. Especially in the rainy season, water into the nozzle was rain sometimes appear white, commonly known as 'white' surface. However, when the weather is sunny and the temperature rises, the 'white' phenomenon will usually disappear naturally. This kind of phenomenon will occasionally appear in some projects, some will be repeated several times, even in some northern areas, until the next year or the temperature. Primer is not in conformity with the requirements and have high water permeability and air permeability. Or using ordinary sealer instead of really stone paint special emulsioni paint primer, for water vapor permeability in the wall to really stone paint coating. If really stone paint is not dry completely and glass transition, when the outside temperature is low or when water vapor is larger, the water in the really stone paint condenses under the paint layer, causing surface become white. Wall enough dry plaster surface density is low, seal leakage or brushing paint not firm, lead to within the walls of water seeping into the incomplete vitrification really stone paint coating. When the outside temperature is low or high humidity, really stone paint the water condensation under the paint layer, causing surface become white. Spraying really stone paint, the air temperature is low, or high air humidity, the dry degree of coating and low degree of vitrification, coating moisture content is too high. In this case, if the paint, the moisture in really stone paint will evaporate more slowly. When the outside air temperature is low or when water vapor is larger, the moisture condenses in really stone paint under the paint coating, lead to surface appear white, sometimes white coating will soften. Use do not conform to the requirements of paint, paint water resistance is poor, or in construction of paint brush, leakage besmear brushs number is insufficient, lead to external water intrusion and surface pale. Really stone paint formulation system defects, poor water resistance, not only causes white surface, cracking fall off. This is KeBao materials in spring rain season really stone paint when construction matters needing attention. The weather is important factor affecting the effects of outer wall really stone paint construction. Therefore, in order to not affect wall really stone paint decorative effect and stable quality, hope to be of help.
