Winter temperature is low, morning and evening temperature difference is large, often cold and humid phenomena, real stone paint, relief, pull hair and other such paint film is relatively thick, drying time is long, in this kind of bad weather conditions, construction is prone to quality hazards, such as frost, alkali, whitening and other phenomena. True stone paint frost after melting, repeated freezing and melting will lead to real stone paint emulsion and additives lose their function, can not be normal film, paint film will appear powdering, sanding, shedding and other phenomena, if encountering rainy days will also appear difficult to remove water marks.
in order to avoid the above problems, in the winter construction should pay attention to the following points
construction environment requirements
01 when the outdoor temperature should be above 5 degrees C, humidity should be less than 85%
.
construction grass-roots requirements
02 wall moisture content is less than 10%, PH is less than 10.
Operation time control
03 yang surface construction time should be controlled at 9 a.m. to 3 p.m., the negative surface should be controlled at 11 a.m. to 2 p.m., make full use of the high temperature period of the day, to allow a certain amount of time for lacquer film film, to ensure that the frost before film.
weather factors
04 should check the weather forecast before construction to ensure that at least 24 hours after construction without rain and snow.
Construction process control
05 Each shelf wall construction should be top-down, once completed, if really can not be completed at once, to leave the pick-up at the more obvious or prominent lines and waistline, to avoid different temperature drying speed caused by different color differences.
site product preservation requirements
06 construction site real stone paint should be placed indoors, classified batch code put, to ensure room temperature above zero degrees, to prevent frost. Paint once frost is strictly prohibited to continue to use!
