How to prevent moisture in basement decoration? Do you have any suggestions?

Hello, Apple Decoration is happy to answer your questions. Generally, before basement decoration, the focus should be on the moisture-proof treatment of the ground and wall, but many owners mistakenly believe that basement moisture-proof is basement waterproofing.

There is an essential difference between moisture-proof and waterproof basement decoration, moisture-proof is moisture-proof (water vapor), and waterproof is groundwater (liquid water), and the molecular density of the waterproof layer is difficult to prevent moisture from entering the room. Moreover, the water vapor in the basement has a certain air pressure, and the simple use of waterproof paint not only can not play a moisture-proof role, but also due to the air pressure, the waterproof coating layer will blister or fall off. Therefore, the basement or the ground on the first floor must be professionally moisture-proof before waterproofing.

a. The basement floor and wall need to be made of special moisture-proof materials. Moisture-proof material uses:

1. It can react with cement to produce a dense 20-30mm moisture-proof layer, the moisture-proof layer and the cement structure are completely integrated, it can allow small molecules of gas to pass through, that is, to ensure the breathing function of cement, and can effectively prevent water molecules from passing. So its vapor barrier is permanent.

2. It is very environmentally friendly, it is inorganic, without any volatiles, and it is non-toxic.

3. Its construction is very simple, the construction period is very short, you only need to use it to spray two on your original cement base, you can walk an hour after construction, and you can carry out the next process after 72 hours.

4. It is very cost-effective, and the cost per square meter is about 15 yuan.

b. How to prevent moisture in the physical basement decoration:

1. To speed up the air flow, ventilation equipment can be installed in a suitable position, and the ventilation equipment can be divided into two kinds according to the power, one is the non-powered exhaust fan, which is a more passive exhaust device, and the exhaust effect is relatively limited. It is also possible to install strong exhaust devices, such as negative pressure fans and axial fans, which may require exhaust ducts. Exhaust fans can be installed if there are windows.

2. The desiccant can be hung indoors. Hang some adsorption desiccant in the basement, the most common is the activated carbon carbon pack, you can also sprinkle some desiccant on some corners and the ground that are more prone to moisture, you can break the mothballs and sprinkle the activated carbon powder there to remove moisture, but the desiccant must be replaced every once in a while.

3. Don't put any plants in the basement, and at the same time you can put a dehumidifier in it, generally the basement is not too big, and the moisture-proof effect of the basement of the dehumidifier is still more obvious.

4. Floor heating can be installed, and it also has a certain moisture removal effect.

5. Check whether there are cracks or damp spots on the basement wall or ground, if there are cracks and aging places that are easy to damp, it is best to shovel off the aging wall that is easy to mold and damp, and the area of the shovel is slightly wider than the aging area, and then brush the sealing paint again.

The basement is generally relatively humid, if it is moisture-proof, it is best to use a reassuring person to do it, I found that Tongji microcrystalline is good, you can also familiarize yourself with it when you have time.

1. Pay attention to ventilation. When the weather is nice, opening the windows and doors in the basement to allow the air to flow well is an excellent way to keep the basement with windows out of moisture.

2. Pay attention to waterproofing. It is very important to do a good job of waterproofing, and you can use waterproof materials to make a waterproof layer, so that you can completely prevent mold problems caused by damp walls.

3. Use the adsorption function of limestone. Because in the process of moisture-proofing, it is not only waterproof, but also has a certain air impurity adsorption function, so limestone is very useful.

Precautions for basement renovation.

The height of the basement is also required, and the basement floor height should not be lower than the meter after decoration, otherwise there will be a sense of depression. After all, the basement is not like other ordinary floors, there are windows with good lighting, natural and comfortable, if the height is still relatively low after decoration, it will be very depressing, and the family does not like to go to that position, so the basement is not much even if it is arranged as a functional area.

It is inevitable that some toxic gases will be produced in the decoration, especially in the basement where the ventilation effect is relatively poor, the toxic gases of the decoration are trapped indoors and cannot be sent out quickly, so in the basement decoration within 2-3 months, people should try not to stay in it for too long, and at the same time put more green formaldehyde sucking plants, open the exhaust fan for a long time to ventilate the basement, so that the toxic gas in the basement can be sent out as soon as possible.

The above content refers to People's Daily Online-Five tips for moisture-proof at home.

(1) Moisture-proof material.

The dampness of the basement is due to being too close to the ground to let the water in the soil soak into the room, and the moisture-proof decoration material can cut off the source, and all the walls and ground in the basement are waterproofed as a whole, and the exterior wall also needs to be waterproof, as far as possible to choose waterproof gypsum board, waterproof coating, diatom mud and other waterproof materials. It is best to choose a waterproof and anti-corrosion material such as light steel keel for the ceiling.

2) Moisture-proof treatment.

Hang some adsorption desiccant, the most common is activated carbon carbon pack, you can also sprinkle some desiccant on some corners and ground that are more likely to be wet, you can break the mothballs and sprinkle them there with activated carbon powder to remove moisture, but the desiccant must be replaced every once in a while.

Try not to plant plants in the basement, and at the same time you can put a dehumidifier in it, generally the basement is not too large, the effect of the dehumidifier is more obvious, and the dehumidification of cold air conditioning also has some effect.

3) Ventilation treatment.

Since the main cause of dampness is ventilation problems, it is best to install ventilation equipment in the basement of the villa, and if possible, you can add a few skylights for ventilation. Ventilation can take away moisture, be careful not to ventilate on cloudy days, rainy days, and after heavy rain in summer, which will bring a lot of moisture indoors.

1. Waterproof layer: Some basic practices of moisture-proof ground in the basement are simply to add the necessary waterproof layer to the ground structure of the basement. If there are more complicated ones, it is necessary to add insulation layer, isolation layer and cement artesian level protection measures above the waterproof layer.

For simple basement moisture-proofing, only the surface is covered with waterproof membrane or directly sprayed with moisture-proof liquid, and the purpose of basement moisture-proof can be achieved.

2. Floor heating moisture-proof: the installation of floor heating is also one of the effective methods of moisture-proof in the basement, basement decoration floor heating so that the indoor temperature of the basement rises and keeps at a certain temperature, so that the indoor can be kept dry and not wet, but it should be noted that the temperature is not too high, otherwise it should cause the indoor to be too dry and uncomfortable.

3. Moisture-proof materials: this is a problem that should be paid attention to when decorating, the basement is a relatively humid place, and it is necessary to pay attention to it when decorating, how to prevent moisture and mildew in the basement decoration? The use of wallpaper, vitrified bricks, moisture-proof effect is better, decoration materials, basement ceiling, floor, wall should be good waterproof.

4. Ventilation and moisture-proof: strengthening air circulation is more helpful to moisture-proof, which can effectively reduce indoor moisture content.

5. Electrical dehumidification: If you encounter rainy weather, the outdoor air humidity is relatively high, and the basement decoration is not suitable for long-term ventilation, you can choose exhaust fans, air conditioners or dehumidifiers and other machines for indoor dehumidification.

6. Dehumidifier: In addition to using various electrical appliances for dehumidification, you can also place more small items with moisture-proof and dehumidification effects, such as desiccant, charcoal bags, etc., for indoor moisture-proofing, but desiccant has a service life and needs to be replaced frequently.

7. Mechanical ventilation for basement decoration: when there is no natural ventilation condition, consider mechanical ventilation and moisture-proof, "National Civil Construction Engineering Design Technical Measures" - HVAC. The number of ventilation and ventilation of the power residential garage is 4 times, and the garage with a construction area of more than 1000 m2 is combined with the smoke exhaust system for the design of the exhaust system.

8. Quicklime: Living in one place for a long time depends on something. For example, if you live in a basement for a long time, it will be better if you pile some quicklime in the corner.

It is important to know that quicklime can absorb moisture and reduce the humidity of the air, so that when the air becomes dry, germs will not grow so easily.

How to prevent moisture in the basement when renovating? What's the best way to do it? application of waterproofing sheets; When you are in the interior decoration, you need to pay attention to the waterproof problem of the basement, the desktop wallpaper and glazed bricks used in the basement of the villa will have a very good waterproof effect, and the ceiling and walls of the basement need to be waterproofed.

Pay attention to natural ventilation and waterproofing; The basement of the villa is an area with poor indoor ventilation, so under these premises, we must pay attention to the natural ventilation of the basement, and improving air convection can reduce the moisture content in the house, which is also beneficial to waterproofing.

plus dehumidifier manufacturers; In the south or in the rainy season, the temperature of outdoor gas will be very high at this time, and natural ventilation for such a long time is useless, so at this time we need to add some machinery and equipment to dehumidify the human factor. For example, add exhaust fans or air conditioners in the basement, or dehumidifiers and other facilities to achieve dehumidification in the room.

moisture-proof agent dehumidification; If the total area of the basement is not very large, then place some moisture-proof agents or small items with dehumidification effect, such as moisture-proof agents and bamboo charcoal bags can be placed in the basement, and remember to disassemble and replace them often. Look at whether there are gaps or wet and cold spots on the pavement and wall of the basement, if there is such a situation, it is best to shovel off the aging wall with mildew and clammy cold, and the total area of the shovel is slightly wider than the total area of aging, and then brush the sealing paint again.

Try not to place green plants in the basement of the villa, and you can place a dehumidifier in the basement, which has a very good effect on the basement dehumidifier with a small total area. The basement floor material is best to choose waterproof characteristics better, you can choose some well-known brands of waterproof floor tiles, so that it is reasonable to avoid the situation of dampness and cold in the basement of the villa.

The effective method of moisture-proof and mildew-proof in the basement is to suspend some moisture-proof agents, which can be packed with activated carbon bamboo charcoal, which can be sprinkled there with mothballs and activated toner powder to remove moisture, and can also be sprinkled with some moisture-proof agents on some corners and roads that are easy to get wet and cold, but be sure to replace the moisture-proof agent every once in a while. Natural ventilation is another way to prevent moisture and mildew in the basement, so the basement of the villa can be equipped with some ventilation and cooling equipment, or a few panoramic skylights can be added to achieve natural ventilation.

It is possible to design the basement to be waterproof and moisture-proof, and the walls should also be treated with moisture-proof treatment to prevent moisture. You can put some formaldehyde removal in the basement, you can also put these green plants, reduce the use of water, put some cleaning supplies, you can also place air fresheners, you can place air purifiers.

How do you protect your basement from moisture? In the past, people used basements as warehouses, but people's minds began to change. If you want to transform your basement into a place for entertaining and entertaining, you definitely need a good design.

Today Tuba Rabbit comes and goes under the consideration of how to prevent dampness and basement renovation under the basement decoration.

How do you protect your basement from moisture?

Secondly, the treatment of the middle layer of the basement is the basis for cement-based penetration and crystallization. In general, it should be scraped with ordinary cement grout. In addition, attention should be paid to the surface and top surface of the cement-based permeable crystal wall. The wall scraping should be done with waterproof putty, both of which are three lives.

Third, the treatment of the basement surface, basement wall and top floor is generally painted. This paint is best used with high-quality waterproof paint. It can also be laid on the floor.

If a floor surface layer is used, then tiles are preferred. Then there are stones, do not use wooden floors, because wooden floors will not be replaced for a long time.

Basic room decoration precautions.

First, moisture-proof treatment.

The basement is not exposed to the sun, the environment is relatively humid, so when decorating the basement, be sure to choose a moisture-proof effect, before buying moisture-proof materials, it is best to check the materials of moisture-proof materials on the Internet, learn more, in order to buy high-quality moisture-proof materials.

Second, indoor lighting.

The basement is darker, the door and window design is not much, if you want to increase the brightness of the basement, it is best to buy some brighter lamps, and the reasonable use of some materials can improve the lighting effect to make the lights in the basement brighter, so that you can use the function of the basement normally.

Third, do a good job of intercepting ditches.

Why cut the ditch, just to prevent the occurrence of heavy rain, rainwater will accumulate on the road surface, will slowly seep into the basement, this time the basement is more dangerous mountains, interception ditch is to avoid this.

Introduction: Many owners like to buy the first floor when buying a house or buying a villa, because the house on the first floor will have a basement, and most owners will transform the basement into an entertainment room. However, because the basement has no sunlight all year round and is relatively humid, we must take moisture-proof measures when decorating.

In this way, we can avoid some unnecessary things from happening. <>

1. How to prevent moisture when decorating the basement?

When decorating the basement, try to choose moisture-proof materials, such as the basement, you can spray moisture-proof liquid, and before using moisture-proof liquid, you must do some basic treatment on the wall. The moisture-proof liquid is usually brushed twice, and each time during construction, the interval is 1 to 2 hours. After the process of moisture-proof liquid is completed, other painting work is carried out after an interval of 5 to 7 days, and the basement decoration is preferred, and it is best to choose a material with a better moisture-proof effect.

For example, moisture-proof paints, moisture-proof wallpapers, moisture-proof tiles, and moisture-proof mats are all very good choices. When dealing with the decoration in the basement, in addition to paying attention to moisture-proof materials, it is also necessary to install some ventilation equipment in the basement, such as fresh air system, dehumidifier, air conditioner and so on. <>

2. Conclusion. This enhances the air circulation in the basement and effectively regulates the dryness and humidity of the room. If the economic conditions allow, you can design a skylight when decorating the basement, so that you can also ventilate through the skylight and increase the circulation of air. Breathing some fresh air is also very good for human health, and can also greatly reduce the humidity in the room.

However, it should be noted that the skylight should not be opened on cloudy or rainy days, otherwise a large amount of moisture will be introduced and the environment will become more humid. You can also put some desiccant in the process of renovating the basement, such as putting some activated carbon desiccant in some corners that are easy to get wet, and replace it every once in a while. The above methods can effectively prevent moisture, so if you need to decorate the basement, you can try it.
