In cold winter, the outdoor temperature is low, many projects must reduce the construction project or even stop working "hibernate", but this has little effect on the general interior decoration works. Specific to the paint, paint construction, there are several other seasons can not be compared to the advantages, but still pay attention to indoor and outdoor temperature, in order to avoid thermal expansion and contraction, causing damage to the construction of a good wall.

Advantages of paint coating construction in winter
First of all, the special weather conditions in winter can make the wall putty quickly solidify, reduce chalking, cracking, but also to speed up the drying time of the paint coating, the filming effect is good. Second, it facilitates the rapid volatilization of formaldehyde and reduces the residual amount of toxic substances in the decoration materials.
Requirements for temperature, ventilation, etc.
It should be noted that when painting winter paint, the room temperature is generally not lower than 10 °C. As long as attention is paid to temperature, ventilation, and the use of supplementary materials, the quality of the paint, the quality of the coating, and the time it takes to maintain the original appearance can be guaranteed. In order to ensure the volatilization of the harmful substances and the drying of the paint surface, it is necessary to open the window quickly after brushing the paint, but it is also necessary to prevent outdoor dust from contaminating the painted surface.
In addition, the outdoor temperature in winter is low, and the window opening is conducive to the volatilization and drying of indoor formaldehyde and other harmful substances and paint products, but it may cause the paint to become powdery or even deteriorate. The dry wall paint or coating is easily frozen. Causes discoloration and peeling of the wall after the spring. Therefore, ventilation should be selected at a relatively warm noon time, ventilation time can not be too long. When the temperature drops rapidly, the window must be closed as soon as possible. After the outdoor temperature approaches the room temperature and the window is opened and ventilated, the problem of paint cracking caused by the shrinkage of the paint surface caused by the low temperature can be effectively prevented.
External wall latex paint often appears cracking during construction in winter, so it should be ensured that the construction temperature is higher than the minimum temperature for paint application, and it is best to apply the paint in strict accordance with the temperature in the product description. According to the general construction experience, the ambient temperature of the coating application should not be lower than 5°C, the ambient temperature of the commonly used mixed color coating application should be at least 0°C, and the ambient temperature when the varnish is applied should not be lower than 8°C. If the temperature is low, an emulsion coalescent can be added. Some owners open the heating during the renovation. Although the indoor temperature is maintained, attention should be paid to the temperature difference between indoor and outdoor to avoid thermal expansion and contraction, because under the strong opposition of cold and heat, it will also cause certain lacquer and coating to be maintained. influences.
Before construction
Before construction, you must pre-fill the cracks on the bottom of the wall to scrape the putty. Putty can not be too thick, try not to use cement putty. In winter, the indoor air is dry and the water loss is fast, which easily causes hollowing, cracking, and uneven walls. Do not apply too thick during construction. Do not apply paint until the paint is dry.

Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.
