How to prevent moisture in the room

the owner of the decoration should pay attention to the indoor moisture-proof foundation project. Because except for a few old houses on the first floor that are in direct contact with the ground, most residential houses have underground floors on the first floor. The main reason for the humidity of this house is that the indoor and outdoor decoration foundation projects are not well done, not climate or geographical factors.

Blind spot 1:

The walls used in the bathroom should be moisture-proof.

Decoration owners all know that the bathroom walls should be waterproof coated to prevent water vapor from seeping out, but this is not the safest way. Because even so, the back of many bedroom cabinets adjacent to the bathroom will be moldy and black.

Duan Xiaodong, an urban construction decoration designer, pointed out that many owners thought it was caused by the leakage of water pipes in the bathroom, but in fact, the water on the bathroom wall penetrated into the cabinets over time. The owner should first turn on the exhaust fan or window to ventilate, and then make a waterproof layer for the bedroom wall at the back of the cabinet.

Duan Xiaodong said that it is best to coat waterproof layers on the walls around the bathroom before tiling. In order to save money, you can also make waterproof layers on both sides of the bathroom wall near other rooms. To be on the safe side, construction workers can be required to add moisture-proof agent to the gaps between tiles, and at the same time, the bedroom cabinet panel next to the bathroom wall should be lined with moisture-proof paper.

moistureproof essentials: wardrobes, cabinets and other furniture must keep a distance from the wall to prevent the water vapor from the bathroom from penetrating into the bedroom through the wall.

blind area 2:

ventilate the floor as much as possible

is the solid wood floor or the laminate floor more suitable for the wet ground on the first floor? This is the moisture-proof topic that housewives talk about the most in the home forum of Dukuaiwan. Jun Chen, the designer of Xuanyi Decoration, thinks that this is not the key point of floor moistureproof.

He explained that in recent years, new houses generally have underground floors, and the so-called first floor is actually the first floor or the second floor, so it is unlikely that the ground will be wet. What's more, nowadays, the floors are mostly lacquered wood, and the wood is effectively isolated from the air by paint. Generally, moisture does not affect the moisture content of wood. The first thing residents should consider is how to use ridges to dry the floor for a long time. Jun Chen suggested that decoration users mix waterproofing agent < P > into cement mortar to make a solid waterproof layer, and then add a moisture-proof pad between the ridge and the floor after paving the ridge.

what about a damp old house without a basement? Duan Xiaodong said that the renovation can only be started from the grass-roots ground. He suggested heightening the keel of the floor and leaving a certain gap so that the ground can keep air circulation with the outside world through the floor.

moistureproof essentials: the floor should not be laid too tightly, and a floor expansion joint of about 1 cm should be reserved between the floor and the wall, leaving room for the expansion and contraction of the board.

Blind Area 3:

Door covers should also be fitted with moisture-proof paper

In order to avoid the deformation of the facade due to high humidity, most families will not choose to install wooden doors in the bathroom, but it is rarely thought that door covers, wooden washbasins and wooden washstands actually need moisture-proof treatment.

Jun Chen, a designer, said that most of the wooden articles in the wet bathroom have been treated by the manufacturer, and the surface is coated with a protective layer of paint, so it is unlikely to be deformed, cracked and warped when it is particularly dry in autumn, but it is best to line the furniture and door covers made by the decoration company with a layer of moisture-proof paper.

moistureproof essentials: keep the bathroom ventilated, and don't mix water into the binder to prevent the wood products from absorbing excessive moisture and causing quality problems.

Blind Zone 4:

The water pipe line is guaranteed for 5 years

If the external wall of some houses cracks and leaks, resulting in water seepage in the walls and damp rooms, this is a congenital deficiency; Then the wall seepage caused by the leakage of the water pipe interface is that the decoration will not pass the day after tomorrow.

Jun Chen told reporters that the most important thing for regular decoration companies is not the surface design and decoration, but the installation of water and electricity pipelines, among which water pipes are more important. Because wires can generally be installed directly from the end of a line, as long as they are constructed according to regulations, it is not easy to have line problems. Nowadays, most of the water pipes used are hot-melt pipes. A pipe line that is only 3 meters long and more than 3 meters is bound to have two water pipes connected together, and there may be leakage problems with interfaces. What's more troublesome is that this kind of pipe leakage problem can not be discovered in a short time. Once discovered, it may bring a lot of inconvenience to the owner's life, and even his neighbors downstairs may suffer.

the designer suggested that the owner should choose a decoration company with a good reputation for construction, and when signing a contract with it, it must be clear that the warranty period of hydropower projects should be slightly longer, usually about 5 years, so that the owner will have no worries.

moistureproof essentials: Try to let the water pipe line pass through the top of the room, instead of installing it on the ground, because the cost of toilet floor renovation is higher than that of the top renovation.

there are many kinds of moisture-proof materials on the market

according to different needs, there are many kinds of moisture-proof materials on the market.

Floor moisture-proof mat: it is an interlayer between the floor and the ground, which is generally laid between the ridge and the floor, and mainly plays the role of moisture-proof, floor protection and flexibility. The reporter learned from the building materials market that some floor manufacturers will give away moisture-proof mats for free with the floor, while others need consumers to buy them themselves. Compared with other building materials, the price of damp-proof mats is cheap, and the lowest price is only 1 yuan per square meter. However, the designer said that the quality of the damp-proof mat is directly related to the service life and effect of the floor, and suggested that consumers should not save money on the damp-proof mat.

waterproof repair agent: it can be used to repair small cracks on the ground of leaking wall and cracks between tiles. At present, there are many convenient restorations for family use in the market, and some of them just need to spray at the leakage gap like pesticides, which is very convenient to operate. If there is a small gap in the wall or floor of a house (especially in the bathroom), you might as well buy this waterproof repair agent and try it yourself. Moisture-proof paste has similar effect.

Moisture-proof gypsum board: Compared with ordinary gypsum board, it contains a silicone oil component, which is mainly used for the ceiling of the bathroom with high air humidity. The reporter learned from Hangzhou New Times Decoration Plaza that it is almost enough to buy more than 2 yuan of moisture-proof gypsum board per square meter.

Waterproofing agent: it can be mixed in mortar and coated on the ground and wall base. It is mainly used for waterproofing and seepage prevention of toilet, kitchen floor and wall during indoor decoration. There are many categories of waterproofing agent products in the building materials market, with prices ranging from 4 yuan to 3 yuan per barrel (about 1 square meters available), and the quality is naturally uneven. Designers suggest choosing products with better brands.

Moldproof and moisture-proof joint filler for ceramic tiles: It is used to fill gaps between ceramic tiles, and its mildew-proof and seepage-proof performance is much better than that of white cement used to fill gaps between ceramic tiles. The price of this caulking agent is not much more expensive than that of ordinary caulking agent. You can buy a big bag for twenty or thirty yuan.

people also have emergency measures to prevent moisture.

if your home is on the ground floor that is in close contact with the ground and you don't plan to carry out large-scale renovation, the low-cost emergency measures provided by users of Dukuai may help you through the wet season.

1. If your humid room happens to have an air conditioner, you might as well use the air conditioner to extract moisture, that is, close the window to start the dehumidification function of the air conditioner, which can help you effectively solve the problem of humidity in the rainy period and protect the household appliances that are afraid of moisture.

2. If your house is humid but well ventilated, make sure the doors and windows are wide open when it is humid inside, and closed when it is humid outside.

3. If only some corners of your house are particularly humid, you might as well put some quicklime mixed with sand in those corners as a desiccant.

4. If the wardrobe with moistureproof layer is still damp, then go to the supermarket to buy some desiccant and mothballs and put them in the wardrobe. However, clothes made of elastic fibers should not be placed with desiccant as far as possible, because the smell of desiccant may make elastic fibers loose and deformed.
