In the north and the south stone paint construction have what different?

Southern HuiNa day is guangdong, guangxi, fujian, hainan and other regions of common phenomenon, related to the southern ocean and moist air. 'Hui' south day appears, the air humidity is becoming saturated, walls and even the ground will be 'water'. Everywhere is wet, the air seems to be able to squeeze out water. Heavy fog is 'back to the south' most vivid expression. All the high-end film, waterproof, anti-fouling, weather resistance coatings have requirements on construction temperature and humidity. The paint used under normal temperature and humidity. Film of the actual drying time more than three days. 'Hui south German' most environmental temperature around 10 ℃, environment humidity above 85%. A longer dry and film forming process. If the humidity continuously, coating will always in the wet state. Therefore, 3 days is the key period, we have to make sure there is enough paint curing time. 2. If the time limit for a project request to painting, must pay attention to painting and prolong the time interval ( Under normal humidity and temperature to coating the time interval of about 4 hours) 。 Usually, can only draw once a day. Dry on the surface of the paint is dry, don't be feel misunderstood. In fact, the film inside the water cannot be released. If the coated in a hurry the next layer of coating, may lead to more problems, such as mold, peeling, layered, foaming, sagging and other risk. In the later. 1. HuiNa day damp environment is very difficult to achieve ideal state of construction. Generally not recommended during this time, or the cold weather (below 10 degrees Celsius Including the specific construction time and the key of 3 days after coating curing period) Stone coating product construction, because the paint film slow drying time affecting the quality of the film, easy to cause a variety of quality problems. 2. If the time limit for a project request to painting, must pay attention to painting and prolong the time interval ( Under normal humidity and temperature to coating the time interval of about 4 hours) 。 Usually, can only draw once a day. Dry on the surface of the paint is dry, don't be feel misunderstood. In fact, the film inside the water cannot be released. If the coated in a hurry the next layer of coating, may lead to more problems, such as mold, peeling, layered, foaming, sagging and other risk. In the later. 3, 'back to south day' would only be bored with child construction. Exterior wall putty winter preparation, dry faster. Each thin batches should be controlled below 1 mm ( The next layer of construction will take place in a layer of dry before, it will easily lead to coating blistering and peeling) 。 The main composition of water resistant putty is cement, the water to harden. HuiNa damp environment, water resistant putty hardening speed will speed up a lot. The last time, therefore, be bored with child after surface drying, must arrange polishing personnel to follow up, and select the appropriate in polishing abrasive paper immediately. Blow be bored with child batch of material with polished interval of not more than 48 hours, in order to prevent the hardened putty in damp environment, caused by polishing. 4. Site management: the requirements of project engineer, supervision and construction unit leaders to strengthen construction management, to ensure the working face is dry, avoid in the process of dry before the next working procedure. Northern region in the north is characterized by alternating between the north and the south wind, wind power is relatively strong. In general, may, after the frequent winds can be improved. The arrival of the strong wind brings the cold air, the temperature drops, the humidity drop. As temperatures rise, spring if precipitation decreased, but not long ago, the ground is dry, the wind dust weather comes easily. Every year in March and April is a period of frequent sandstorms. How to avoid? The lowest temperature in 5 - (1) in northern area 10 ℃. Paint construction should be as much as possible in the morning 10:00 to afternoon 16:00. If the temperature is too low, paint film will craze. (2) pay close attention to weather, rainy days to stop the construction. After the rain, to base material for testing the water content, reach the standard rear can coating, lest paint film is bubbly. (3) regular test base material surface temperature and air relative humidity. When the surface temperature is less than 5 ℃ or air relative humidity higher than 85%, should stop the construction. (4) when the environmental relative humidity is higher, water-based paint dry slowly, forming film. The gap between the coating to spray paint should be extended appropriately. Thin coating products are usually every other day to paint again. Thick coating, such as the middle tier of the elastic texture coating and paint, anaglyph bone paste, usually 2 really stone paint. If the time limit for a project request to painting, must pay attention to painting and prolong the time interval ( Under normal humidity and temperature to coating the time interval of about 4 hours) 。 Usually, can only draw once a day. Dry on the surface of the paint is dry, don't be feel misunderstood. In fact, the film inside the water cannot be released. If the coated in a hurry the next layer of coating, may lead to more problems, such as mold, peeling, layered, foaming, sagging and other risk. In the later.
