    Summer is the peak period of architectural decoration construction, most projects will choose to start in the summer, but the summer weather is unpredictable, more variable, from time to time high temperature, from time to time rain, from time to time dry, from time to time humid.
    and paint product construction on the temperature, humidity, etc. have certain requirements, therefore, the summer weather changes on the external wall paint construction impact is very large, for high temperature weather construction may occur problems, need to pay attention to the following things Oh!
    01
    substation normal construction, 6-48 hours can be dried and polished the best results, if not timely grinding and encounter high air humidity, putty will once again be moist and cured. At this time, the putty substation will appear dry and not dry phenomenon, and in the putty surface to form a layer of high hardness with a glossy film, the wall putty outside hard pine, the post-order construction is very easy to appear coating film de-layering phenomenon .
    02
    summer direct sunlight wall temperature is very high, the primer rolled quickly into a film, can not penetrate into the outer wall grass, resulting in poor adhesion, it is recommended to avoid direct sunlight construction, and appropriately increase the amount of dilution, so that the primer fully penetrates into the putty base, improve adhesion.
    03
    coating drying and film-forming need to be carried out under certain temperature and humidity conditions, suitable temperature between 10-35 degrees C, the temperature of the coated wall can not be greater than 35 degrees C, forced high temperature construction will affect the final film performance;
    04
    suggested that the construction of the exterior wall to adjust the construction time, avoid 11 a.m. to 3 p.m. between 11 a.m. to 3 p.m. each day higher temperature period, do a good job of construction personnel to prevent heat and cooling measures, the appropriate amount of preparation of wind oil essentials and other heatstroke drugs.
    05
    high temperature weather construction materials dry fast, the construction of internal and external wall coatings need to maintain good construction consistency, if a large area of basket construction, the need to moderately increase the number of workers on the same construction work surface, improve work efficiency, maintain the wet connection of the work surface.
    06
    all on-site materials should be placed in indoor shady ventilation, prohibit the material directly exposed to outdoor sunlight, so as not to cause unnecessary product quality problems.
    07
    Pay attention to listen to the weather forecast, timely understand the weather changes, fully consider the external wall after the completion of the construction of the required drying time, to prevent just finished construction, began heavy rain, resulting in unnecessary material and labor losses.
