Floor crack humidifier "moisturizing"
The cold comes from the soles of the feet. In recent years, many people have a soft spot for floor heating. At this time, in winter home maintenance, the floor occupies the primary position.
Industry insiders remind that families who decorate in winter need to consider the condensation phenomenon of wooden floors during transportation. It is best to leave the floors home for 24 hours before unpacking. Many people think that in winter, let the outside air in, the indoor temperature drops, and the floor cracks naturally weaken. In fact, the real cause of cracks in the floor comes from humidity, not temperature. In winter, many families will use humidifiers for moisturizing treatment, and the indoor humidity should be kept above 40%, which is not only beneficial to human health, but also beneficial to the maintenance of wooden floors.
Shrinkage, expansion, arching, cracking and other phenomena. The problem of wooden floor not only appears in winter construction projects. What should I pay attention to when decorating wooden floors in winter?
First, the wooden floor before installation
1. In order to make the wooden floor more suitable for the temperature and humidity of the paving environment in the north or areas with large temperature difference, you should go through the delivery formalities 7 days in advance. Please don't unpack the floor when it is transported to the construction site.
2. The floor meets the installation requirements. If there are special circumstances such as geothermal and radiator, please explain to the shopping guide in advance.
3, the ground must be clean, without sundry, furniture and other items please temporarily removed before installation.
4, the ground elevation difference within 2 meters below 5mm, more than 5 mm should be leveled first, the ground elevation difference is not very serious, such as uneven ground, it is recommended to use gypsum for local leveling.
5. If the floor is not dry, it is easy to cause floor deformation after installation. Please make sure that the ground is dry. If the ground has just been leveled with cement, the installation will take at least one month.
Second, after the wooden floor is installed.
1. The installer will show you the warranty card.
2. The installer will explain the maintenance of the wooden floor to you.
3. If the glue is not completely cured, please move into furniture and other items after 48 hours.
4. Vacuum or clean the floor regularly to prevent sand and other hard objects from accumulating and scratching the surface of the wooden floor. Door mats can be placed outside the door to avoid bringing sand or friction dust into the room;
5. When the indoor humidity is greater than or equal to 80%, it is advisable to ventilate and remove the humidity. If the outdoor humidity is greater than the indoor humidity, you can close the doors and windows to keep the indoor humidity low. If the outdoor humidity is less than the indoor humidity, open doors and windows to reduce the indoor humidity. If the weather is humid and muggy, please use the air conditioner to get wet.
6. When the indoor humidity is less than or equal to 40%, humidification measures should be taken. For example, when heating or floor heating is used in autumn and winter in northern China, the indoor temperature rises and the humidity drops obviously. When the air relative humidity is lower than 30%, the wood floor will crack and crack. GB/T20238-2006 stipulates that the ambient humidity is 40%.
Therefore, in winter, it is necessary to use humidifiers to raise the indoor air temperature and keep the indoor air humidity at 50%-70%.
