The reasons for the winter because the temperature and outdoor construction projects in many projects to be reduced or even lay "dormant." But the interior decoration in general have little effect. Specific to the paint, coatings of construction, there are several other seasons unparalleled advantage, but still have to pay attention to indoor and outdoor temperature, so as to avoid thermal expansion and contraction, the construction of the wall a good cause some damage.
First of all, winter can rapidly solidified putty wall surface to reduce the powder, crack, but also speed up the paint drying time, film effect. Second, it is conducive to the rapid evaporation of formaldehyde to reduce toxic materials in the decoration of the residues. But note that the construction of winter paint brushing, room temperature generally not less than 10 ℃. Just make sure the temperature, ventilation and add a few aspects of application materials, can ensure that paints, coatings to maintain the original appearance of the construction quality and time. To ensure that the volatile and hazardous substances drying paint, paint materials in the ventilation window soon after, but also outdoor dust coated to prevent pollution.
Winter outdoor temperature is low, open the window in favor of indoor formaldehyde and other harmful materials and paint products, volatile and dry, but may cause deterioration or paint powder, no dry wall paint or coating can easily be frozen, resulting in the spring after wall color, from the skin. Therefore, ventilation should be selected in the warmer afternoon hours, ventilation time not too long. When the temperature dropped rapidly as soon as possible close windows, and other outdoor temperature close to room temperature and then the ventilation window to prevent the temperature is too low can cause the paint finish cracking caused by contraction of the issue.
In addition, Shang Yun added, before construction must be pre-filled cracks in the underside of the wall, scraping putty good. Putty does not grab too thick, try not to use cement putty. Winter indoor air is dry, water loss quickly, easily lead to hollowing, cracking, uneven walls. Construction is not applied too thick, the coating under dry before apply a defined level. Exterior Latex for construction in the winter often cracking phenomenon, it should ensure that the construction of the minimum temperature is higher than the temperature coating application, in strict accordance with product description best temperature brushing.
In accordance with the general experience in construction, paint apply a defined ambient temperature not lower than 5 ℃; commonly used in mixing paint at least during the construction of the ambient temperature above 0 ℃; varnish Shitu the ambient temperature is not lower than 8 ℃. If the temperature is low, you can add latex coalescent. Some owners open during renovation Heating, though the indoor temperature is kept, but pay attention to indoor and outdoor temperature, so as to avoid thermal expansion and contraction, because in the cold and hot under the strong against the will of the paint, coated to maintain some impact .
