Coating common sense: paint construction in autumn and winter can reduce the phenomenon of chalking and cracking

Core tip: first of all, the special weather conditions in winter can make the putty on the wall surface solidify rapidly, reduce the pulverization and cracking, accelerate the drying time of the paint and coating, and achieve good film-forming effect Secondly, it is conducive to the rapid volatilization of formaldehyde and the reduction of the residues of toxic substances in decoration materials Requirements for temperature, ventilation and other conditions It should be noted that when painting in winter, the room temperature should not be lower than 10 ℃ As long as we pay attention to the temperature, ventilation and the application of auxiliary materials, we can guarantee the construction quality and original maintenance time of paint and coating In order to ensure the volatilization of harmful substances and the drying of paint surface, it is necessary to Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: first of all, the special weather conditions in winter can make the putty on the wall surface solidify rapidly, reduce pulverization and cracking, and accelerate the drying time of paint and coating, with good film-forming effect Secondly, it is conducive to the rapid volatilization of formaldehyde and the reduction of the residues of toxic substances in decoration materials The requirements of temperature, ventilation and other conditions need to be noted that the room temperature is generally not lower than 10 ℃ when painting in winter As long as we pay attention to the temperature, ventilation and the application of auxiliary materials, we can guarantee the construction quality and original maintenance time of paint and coating In order to ensure the volatilization of harmful substances and the drying of paint surface, windows shall be opened for ventilation soon after painting, but the pollution of outdoor dust on the paint surface shall also be prevented In addition, the outdoor temperature is low in winter, opening windows is conducive to the volatilization and drying of indoor formaldehyde and other harmful substances and paint products, but it may make the paint powdered or even deteriorated The wall paint or paint that is not completely dried is easy to freeze, resulting in wall color change and peeling after spring Therefore, the ventilation should be in a warm noon period, and the ventilation time should not be too long When the temperature drops rapidly, the windows should be closed as soon as possible When the outdoor temperature is close to the indoor temperature, the windows can be opened for ventilation, which can effectively prevent the paint cracking caused by the paint shrinkage caused by the low temperature The exterior wall emulsion paint often cracks in winter, so the construction temperature should be higher than the minimum temperature of coating construction, and it is better to brush strictly according to the temperature in the product description According to the general construction experience, the ambient temperature of coating application shall not be lower than 5 ℃, the ambient temperature of common color mixing coating construction shall be at least higher than 0 ℃, and the ambient temperature of varnish application shall not be lower than 8 ℃ If the temperature is low, emulsion film builder can be added Some owners turn on the heating when they decorate Although the indoor temperature is kept, they should pay attention to the indoor and outdoor temperature difference to avoid the expansion and contraction of heat Because under the strong resistance of cold and heat, it will also have a certain impact on the maintenance of paint and coating surface Before construction, the cracks at the bottom of the wall must be filled in advance and the putty shall be applied Putty should not be too thick, try not to use cement putty In winter, the indoor air is dry and the water loss is fast, which is easy to cause hollowing, cracking and uneven wall surface The coating shall not be too thick during construction, and the next layer can be applied after the coating is completely dry Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
