[Wooden door] How to prevent the wooden door of the bathroom from becoming moldy?

How to prevent the wooden door of the bathroom from becoming moldy? What should I do if the bathroom wooden door is easy to get moldy? Everyone may have had a similar experience. Wooden doors and doorframes in the bathroom of one's own home or friend's home are often moldy and black. The scope gradually expands from bottom to top. So some people simply use aluminum alloy, plastic steel, or PVC, glass and other materials that will not be moldy. But indoor doors always feel uncomfortable with this kind of door. How to solve it? First of all, we should start with the cause of mildew. Mold is produced under the long-term action of water and moisture. The key words are "moisture" and "long-term". Then the bathroom should be well ventilated. First, there should be windows, and they should be as big as possible. In this respect, Shenzhen residents are luckier than the mainland, where toilets are usually in dark rooms without windows. The second is to add an exhaust fan. Everyone who lives in the hotel knows that the bathroom switch of the hotel is connected with the exhaust fan, so the exhaust fan must be turned on when the light is turned on. Hotel bathrooms have no windows, but who has seen the bathroom doors (mostly wooden doors) of five-star hotels moldy? In addition to the thoughtful design, the construction technology is also exquisite, which is not easy for non-professionals to understand in detail. Third, dry and wet areas should be separated. It should be said that the walls and floors in other areas of the bathroom are dry most of the time except the shower area. There are still many stresses on construction technology and joint structure. The waterproof treatment of bathroom wall and floor only solves the waterproof problem inside and outside the bathroom. However, the water above the waterproof layer under the tile will be sucked in from the place without paint by the contact surface between the wooden frame and the wall. The paint on the surface of the wooden frame will make the sucked water unable to disperse, and mold will be annoying from the inside. Therefore, first of all, the junction between the wall and the ground, the junction between the door frame and the wall, and the junction between the sink and the bathtub and the wall should be sealed with silica gel to prevent water from infiltrating. Secondly, the wooden door frame should be pretreated before installation, especially the cross section of the wooden frame, which should not only be sealed with paint, but also soaked in varnish for a period of time before installation. Of course, it is best to isolate the wooden frame from the ground in structure, such as using stone and stainless steel. If only the bottom of the door cover is moldy, it has little to do with waterproof, so it is ok to make the door cover again. But the wood used to make the door cover must be soaked in paint first. It is a common problem that the wooden door in the bathroom is moldy, which is difficult to handle. It is recommended to use metal or rubber doors as door covers.
