Coating technology: Construction Strategy of interior wall coating in winter

Core tip: with the arrival of winter, the temperature drops sharply, but there are still many owners busy with the decoration of new houses The low temperature in winter and the slow drying of the coating bring a lot of inconvenience to the construction in winter, which is the season of wall paint construction problems For these, some requirements for coating construction in winter are listed as follows: temperature requirements It is recommended to carry out indoor temperature detection every time when brushing The wall temperature shall not be lower than 5 ℃ and the ambient temperature shall not be lower than 8 ℃ during coating construction It is not recommended to carry out construction when the ambient temperature is lower than 8 ℃ for several consecutive days If there is warm Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: with the arrival of winter, the temperature drops sharply, but there are still many owners busy with the decoration of new houses The low temperature in winter and the slow drying of the coating bring a lot of inconvenience to the construction in winter, which is the season of wall paint construction problems For these, some requirements for coating construction in winter are summarized as follows: temperature requirements suggest that indoor temperature detection should be carried out every time coating is applied, wall temperature should not be lower than 5 ℃, ambient temperature should not be lower than 8 ℃, and construction is not recommended if ambient temperature is lower than 8 ℃ for several consecutive days If there is heating or other heating methods, the indoor temperature of the room shall not be lower than 10 ℃, and the door, window and other places shall be closed before construction If the sealing is not good, the door, window or the winded part will crack The humidity requirements ensure that the wall moisture should not be too heavy (the moisture content should not be higher than 10%), and the air humidity should be less than 85%, so as to avoid low temperature, the wall moisture volatilization will not affect the quality of the paint film, resulting in such symptoms as powder removal, long hair, blistering, cracking, etc The wall base layer and wall base layer must have enough maintenance time, and the maintenance in winter is required to be more than 4 weeks When the water content is less than or equal to 10% and the pH value is less than or equal to 10%, the defects such as watermark, blister, alkali return and so on shall be avoided Putty powder shall be selected in accordance with the requirements of JC / t3049 putty for interior use of buildings, mainly with good adhesion, enough strength, no looseness and low alkalinity (pH less than 10) When applying putty, it is necessary to control the thickness of the putty, rather than the thickness of the putty Each time the putty should be applied after the first time the putty is dry The putty layer must be completely dry before the construction of the bottom and top coat, to avoid cracks, blisters and other defects Painting requirements: painting, mixed painting, air spraying and airless spraying shall be carried out strictly according to the construction ratio, and shall be fully mixed evenly It is strictly prohibited to apply thick coating for a single time, and to mix too much water to avoid the paint film cracking or powder falling caused by this Sufficient drying time shall be kept between two finishing coats to avoid sagging and cracking The recoating time is generally required to be more than 4 hours in winter and 2 hours in summer, with appropriate extension in rainy and humid weather 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,
