How long does it take for formaldehyde to evaporate?

According to different release sources, its volatilization time is also different. The formaldehyde in wall coating can almost volatilize in 7~ 15 days, the formaldehyde in wallpaper adhesive is more than 18 months, and the formaldehyde in large core board is 15 months. The best treatment is ventilation. Or buy some plants to absorb formaldehyde. Generally speaking, plants and herbs with large leaves absorb formaldehyde better, such as chlorophytum, Huwei orchid and so on.

Extended data:

The main function of window ventilation is to let the air circulate, take away harmful gases such as formaldehyde, ammonia and benzene volatilized from decoration materials, and also make the wall paint dry quickly. However, outdoor cold air is also easy to deteriorate the car paint, and it is also easy to freeze the wet car paint. Therefore, it is necessary to open the window moderately, and the ventilation time is best around noon, so as to achieve a lasting purification effect.

Putty should not be scraped too thick. Because the indoor air is dry and loses water quickly, otherwise it will easily lead to hollowing, cracking and uneven walls. When painting, the oiler should apply the paint strictly according to the temperature specified in the product description. The ambient temperature of paint construction should not be lower than 5℃, and the ambient temperature of varnish construction should not be lower than 8℃. Oil workers should pay attention to "keeping warm" and open doors and windows for ventilation after being fully dried.
