Problem 1: Cement mortar is easy to freeze
The lower temperature will make the cement mortar harden quickly, but this is not freezing, but it is frozen. After the ice in the cement mortar is melted, its adhesive force is reduced and it is easy to fall off.
Solution: Add antifreeze
Under normal circumstances, the room temperature above 0 °C will not have a significant impact on the paving tiles, so as far as possible at a higher temperature when mixing cement mortar. It is understood that some decoration companies will, in the winter construction, add anti-freeze agents to the cement mortar.
At the same time, because the outdoor temperature is low, the tiles cannot be used directly after entering the site, but should be placed in the room for a period of time. After the temperature is the same as the room, the estimated amount of the day is used, and the tile is immersed in water of 5° C. or higher. After the tiles are immersed in water, the bonding strength with the cement mortar can be strengthened to reduce the chance of shedding.
Challenge 2: Form a non-toxic illusion
The harmful gases such as benzene and formaldehyde are slow to evaporate in the winter, but with the increase of temperature, the harmful gases will accelerate the volatilization.
Solution: Do not rush to stay
After the winter renovations, many people feel that the interior is not too “decorative†and they stay in it, but in fact, this is the illusion caused by the low temperature. Therefore, it is recommended that consumers in winter decoration, even if there is no smell in the room, still need to stay for a month or so. During this period, the ventilation in the windows should be moderate. It is recommended to ventilate the air before and after noon in order to avoid the sudden drop in the indoor temperature. The negative effect of decorative materials.
Problem 3: Heating and dehydration cause wood dehydration
In winter, when the weather is dry, wooden products are easily deformed due to “dehydration†and “distortionâ€.
Solution: proper left seam
All wooden materials should be placed in the room for three to five days before installation to allow them to adapt to the indoor humidity. After the moisture content is close to the indoor level and then installed, it can minimize the deformation of the wood in the future.
At the same time, if there is heating in the indoor construction, we should also pay attention to control the site humidity, to avoid excessive drying of the environment to increase wood deformation, and then without humidification equipment, you can place a water basin around the heat source for humidification.
In addition, in order to reduce the swelling of wood products due to water absorption during the summer, expansion joints should be left during winter decoration.
Problem 4: The paint dries slowly
In winter, the temperature is low and the sunshine is weak. The paint on the wall is not easy to dry, and cracks such as hair may easily appear in the future.
The solution: coating thinning
The wall surface treatment usually requires 5 steps of brushing the interface agent, leveling, patching, two coats of primer, and one coat of paint. After the previous step is processed, it must be dried before entering the next step, otherwise the wall will be There will be cracking, drumming and other phenomena.
In winter, the temperature of the paint application environment is usually required to be above 5 degrees. Therefore, it is advisable to apply the wall painting operation between 10:00 am to 4:00 pm. During the construction process, the number of window openings should be minimized to avoid freezing of the paint. Or excessively dry.
