Nowadays, people pay more attention to their living environment, so when decorating a house, they will choose suitable decoration materials based on your own preferences and needs. However, when choosing decoration materials, everyone must pay attention to it. method. Not long ago, Zhongtaojun saw a piece of news: Just five months after the new house was decorated and moved in, severe mildew appeared on the walls. What is the reason that causes this phenomenon? Let's take a look.
1. What are the causes of mold on walls?
When we are renovating a new house, whether we are the owner responsible for on-site supervision or a construction team responsible for on-site construction, we will encounter a problem comparable to "chicken and egg" - when we lay tiles, what should we do? Should you lay wall tiles first or floor tiles first?
Some masters will suggest that we lay floor tiles first and then wall tiles. Friends who have experienced renovations all know that after the floor tiles are laid, they must be allowed to sit for at least 2-3 days before they can be stepped on. The workers started from indoors and worked toward the door. After finishing the work, they locked the door and closed the place.
So, this means that after the floor tiles are laid, the construction workers will have to stop work for about 3 days. At this time, many people will think that in order not to affect the construction period, it would be better to lay the wall tiles first?
In fact, according to experience, in order to ensure the decoration effect, it is more reasonable to lay the floor tiles first and then the wall tiles. Because after laying the floor tiles, the ground will be flat. At this time, laying the wall tiles from top to bottom will be easier to operate and reduce the difficulty of construction. When laying wall tiles, even if there is a height difference, you can still cut the bricks to remedy the problem of size deviation, because adjusting the height difference of floor tiles is much more difficult than that of wall tiles, which will undoubtedly increase the difficulty of laying and the construction period in disguise.
Another advantage is that by laying the floor tiles first, the gaps between the floor tiles and the wall tiles will be smaller, which can prevent water from flowing into the gaps between the tiles, better protect the wall and tile surfaces, and reduce the impact of the tiles on the cement layer. , at the same time, it can better achieve waterproof and moisture-proof effect. For those who love beauty, this paving method is more beautiful and elegant.
According to the construction period issue mentioned earlier, many masters will chooseChoose to lay wall tiles first, then floor tiles. The reason is also very simple. The wall tiles are laid first, and the wall leveling and construction period are relatively long. While the wall tiles are being laid, woodworking, painting and other processes can be carried out simultaneously in the house.
If the floor tiles are laid first, then a 3-day construction period needs to be set aside. If the wall tiles are laid first, the workers will leave the bottom row empty, and then fill it up after the floor tiles are laid, and press the wall tiles on top of the floor tiles - whether the wall presses the ground or the ground presses the wall, this way It is the most waterproof. However, if you pave in this way, there is always a bug that is inevitable - after we move in, if water splashes on the wall fall to the ground, it will flow into the cement layer along the gaps. If this happens for a long time, mold in the corners is inevitable. . And the waterproof layer is easily damaged.
2. How to deal with mold on the wall?
1. When mildew spots appear on the wall, you can first use a (dry) toothbrush to brush away the mildew stains, and then use a soft cloth dipped in alcohol to wipe it gently. This can dry the wall and prevent the growth of mold.
2. Add bleach (powder) to water at a ratio of 1:99 and pour it into a spray bottle. Spray it on moldy walls to immediately solve the problem of moldy walls. Wipe the wall with a rag; then wash it with clean water. After the wall is dry, apply anti-mildew paint to prevent moisture for a long time. In addition, there is a convenient household waterproofing repair agent on the market. You only need to spray it on the cracks in the leaking wall and floor like an insecticide. It is very convenient to operate.
3. When the mold is not too serious, it is enough to use 80% alcohol to wash the walls. Pay attention to ventilation when cleaning, and wear protective gloves, masks and glasses. To avoid the recurrence of mold, attention should be paid to thorough drying of the walls, elimination of the causes of mold, and proper heating and ventilation.
4. During humid weather, open windows as little as possible. In addition, try to keep the walls as dry as possible. In humid weather, you can use dehumidifiers, air conditioners, and fans to absorb moisture from the walls. Once moisture appears on the walls or furniture, it should be wiped off immediately with a dry cloth.
3. What are the dangers of mildew on walls?
The reason why the walls become moldy is that in the south, the moisture in the air is heavier. When it encounters super-cooled surfaces, it will condense and produce water droplets. When water vapor adheres to and infiltrates the surface of the wall paint filmFor a long time, mold will easily appear, usually on suspended ceilings, dark corners and other places.
Mold on the wall may also be caused by the poor quality of the paint used on the wall. The antibacterial and anti-mildew properties of the paint are poor and water vapor can easily penetrate the wall, causing mold to grow.
After the wall becomes moldy, the wall will emit mold spores. Mold spores are very harmful to our human body. Once they flow in the air and are inhaled into the respiratory system of the body, they will multiply rapidly. If mold is exposed to and inhaled for a long time, it can easily cause respiratory diseases, allergies, etc.; people with low immunity can cause headaches, fever, mucous membrane inflammation, etc. after inhalation.
The above is the relevant content about Wall mildew. Therefore, when decorating your house, you should pay attention to the relevant preparations, otherwise it will be too late to regret it. Of course, when decorating a house, it is recommended that you hire an experienced construction team to carry out the construction to ensure the overall construction quality.
