5 serious consequences of mold on walls
——Causes of wall mold and anti-mold solutions of microcement whole-house coatings
In Hong Kong, a humid subtropical region, moldy walls are a very common household problem. Whether it is a new or old building, as long as it encounters the return of the south wind, the plum rain season, or poor indoor ventilation and structural water seepage, the walls will soon have a little black spot or even a large patch of mold. These molds not only affect the appearance, but also bring multiple health and structural risks. The following will analyze in detail the causes of moldy walls, the five major serious consequences, and introduce how to use microcement as a whole house wall coating to effectively prevent mold and create a healthy and comfortable home environment.
1. The main reason for wall mold
1. Humidity is too high
Hong Kong is in a high humidity environment for a long time, especially from May to September every year, when the air humidity often exceeds 70%. When the indoor humidity is too high, moisture easily condenses on the wall surface, providing ideal growth conditions for mold. Bathrooms, kitchens, basements and other areas are more likely to be affected.
2. Poor ventilation
In order to save energy, modern buildings have high air tightness. However, if there is a lack of proper ventilation, moisture cannot be discharged and moisture will accumulate in corners or hidden locations, causing mold to naturally grow.
3. House structure or water seepage problems
Structural problems such as wall cracks, aging of the exterior wall waterproofing layer, and drainage pipe leakage will allow moisture to penetrate into the wall, and long-term moisture will cause mold to continue to grow.
4. Lifestyle
Hanging wet clothes, cooking for a long time, not opening windows after taking a shower, etc. will increase indoor humidity and promote mold growth.
5. Improper cleaning and accumulation of debris
Clutter piled up in corners and behind furniture creates poor air circulation, which makes it easy for moisture and dust to accumulate, providing nutrients for mold.
2. 5 serious consequences of mold on the wall
1. Impact on health
Mold spores can float in the air and, when inhaled, can cause allergic reactions (such as coughing, nasal allergies, skin eczema), respiratory infections, and even worsen the symptoms of asthma and people with weakened immune systems. Some molds can also release toxins, and long-term exposure can affect nerve and organ function and even increase the risk of cancer [5][6][12].
2. Destroy the beauty of your home
Black spots, yellow spots, peeling, bubbling or cracking on the walls seriously affect the appearance of your home. Even if you repaint, if the moisture problem is not solved, the mold will soon reappear.
3. Damage to building structures
Long-term moisture can damage the wall structure, causing peeling, chalking, cracks, and even affecting the load-bearing capacity. Water seepage in the exterior wall is more likely to affect neighbors and cause maintenance disputes.
4. Increased maintenance costs
If wall mold is not dealt with in a timely manner, the problem will continue to worsen and eventually require large-scale renovations or redoing the waterproofing layer, which is time-consuming, troublesome and costly.
5. Affected items and furniture
Mold can spread to furniture, clothes, books, etc. near the wall, causing mold and deterioration, resulting in loss of household property.
3. Traditional coatings are difficult to cure mold
Even if ordinary paint or wallpaper is claimed to be moisture-proof, it is still difficult to withstand the high humidity in Hong Kong for a long time. Especially if the wall itself has water seepage or structural problems, traditional coatings will soon be eroded by moisture, causing mold and peeling again. Even if you clean it diligently or treat it with bleach, it is only a temporary solution and not a permanent solution.
4. Microcement - the ideal choice for whole house mildew and moisture resistance
Microcement is a new type of environmentally friendly coating, which is made of cement, aggregate and additives. Special sealants can be added to the surface. It has the following multiple advantages [7] [10] [13] [15] [17] [19]:
1. Super waterproof and mildew-proof
Microcement has a tight structure and a sealing coating, which can effectively block water vapor penetration. Even in high-humidity spaces such as bathrooms and kitchens, it can remain dry for a long time and prevent mold growth.
2. Seamless and easy to clean
Microcement can seamlessly cover the entire wall, without tile gaps or wallpaper seams, and is not easy to accumulate dirt and mold. Daily cleaning with a neutral detergent is sufficient, making maintenance simple.
3. Durable and strong, not easy to peel off
Microcement has strong adhesion, is wear-resistant and impact-resistant, and will not bubble, peel or discolor even after years of use, and its service life can reach decades.
4. Beautiful and versatile, suitable for all styles
Microcement has a variety of colors and textures to choose from, and can be perfectly matched with modern simplicity, industrial style, Nordic style or Japanese natural style.
5. Environmental protection and health
Microcement is non-toxic, formaldehyde-free, safe and friendly to humans and pets. It is suitable for families with children, the elderly or people with sensitive constitutions.
5. Suggestions for the application of microcement in the whole house
1. High humidity areas such as bathrooms, kitchens, basements, etc.
Fully cover the walls and floors to completely prevent moisture penetration and mold growth.
2. Living room, bedroom, entrance
Create seamless walls to reduce dust accumulation in dead corners and enhance the texture and comfort of the space.
3. Commercial space, office
Durable and wear-resistant, easy to clean, enhancing your professional image.
VI. Conclusion: Choose microcement to prevent mold and protect a healthy home
Mold on the wall not only affects the appearance, but is also an invisible killer of health and structure. Instead of renovating and cleaning every year, it is better to choose microcement whole house paint at one time to fundamentally solve the moisture and mold problems. You can enjoy a long-lasting clean, healthy and comfortable ideal home without fear of Hong Kong's humid weather.
