Recently, many areas across the country have been hit by continuous heavy rainfall. The damp and muggy weather not only affects travel but also causes many families' walls to suffer - water seepage, mold, peeling... Looking at the mottled wall plaster, my mood also felt "wet". How can we keep the walls of our home dry and clean during the rainy season?
Moisture-proofing of walls during the rainy season
With the arrival of the rainy season, the air humidity increases sharply, and the dampness of the walls has become a problem for many families. Dampness not only causes the wall plaster to peel off and mold to grow, but may also trigger health problems such as respiratory diseases and allergic reactions. Traditional moisture-proofing methods often only address the symptoms but not the root cause, and can only temporarily alleviate the problem. To fundamentally solve the problem of damp walls, it is necessary to block the invasion of moisture from the source and enhance the moisture-proof performance of the walls through scientific means.
1. Strictly control construction standards to lay a solid foundation for moisture prevention
Wall moisture-proofing should start from the decoration stage. Before construction, a humidity meter should be used to measure the moisture content of the wall to ensure that the value is below 8%. Otherwise, the moisture will be trapped within the wall and is prone to seep out through capillary action during the rainy season, causing the wall fabric to mold and the paint to peel off. For damp areas such as basements or the first floor, waterproof mortar or waterproof coating should be applied to the walls to form a physical barrier. Before pasting wall fabric, it is essential to apply a base film. This can not only seal the alkaline substances in the base cement but also enhance the adhesion of the glue, preventing moisture from penetrating.
2. Technology-enabled moisture-proofing
During the rainy season, the indoor humidity often exceeds 70%, and at this time, technological means are needed to regulate the environment. The dehumidification mode of the air conditioner can quickly reduce the humidity, and when combined with the timing function, it can prevent excessive energy consumption. Dehumidifiers are suitable for local damp areas such as bathrooms and cloakrooms. Dehumidifying for 2 to 3 hours a day can significantly improve air humidity. If you are looking for a low-cost solution, you can place quicklime bags in the corner. One kilogram of quicklime can absorb about 0.3 kilograms of water, but they need to be replaced regularly to prevent secondary pollution.
3. Check the leakage points and block the moisture channels
The dampness problem of walls often stems from hidden leakage points, such as cracks in exterior walls, joints of doors and Windows or around pipes. During the rainy season, rainwater seeps into the interior of the wall through these tiny gaps. Over time, the accumulation causes the wall surface to become damp. Therefore, the first step is to conduct a comprehensive investigation of possible leakage locations. A high-pressure water gun can be used to simulate rainfall and observe whether there are water stains penetrating the wall. For indoor areas, it is necessary to check areas prone to water accumulation such as corners and ceilings. Once cracks or holes are found, they should be promptly repaired with waterproof sealant or cement mortar to ensure the wall's airtightness and physically block the path for moisture to invade.
A Guide to Choosing Wall Fabrics for the Rainy Season
Choosing the right wall fabric can not only enhance the style of your home but also effectively resist the invasion of moisture. However, not all wall fabrics are suitable for damp environments. When choosing, one should take into account moisture resistance, breathability and ease of cleaning.
1. Prefer moisture-proof wall fabric materials
It directly affects the usage experience during the rainy season. Although non-woven fabric wall fabric has good air permeability, its moisture resistance is relatively weak and it is prone to mold due to moisture absorption. After waterproof treatment, the surface of the chemical fiber wall fabric forms a dense film layer, which can effectively block water vapor. However, it is necessary to pay attention to choosing environmentally friendly glue to avoid excessive formaldehyde. Hot adhesive base wall fabric is the preferred choice for the rainy season. It directly applies hot melt adhesive on the fabric surface, eliminating the need for additional gluing during construction. This reduces the nutrient sources for mold growth and ensures a dense adhesive layer with excellent moisture-proof performance.
2. Pay attention to the moisture-proof process
High-quality wall fabric needs to undergo triple treatment processes of waterproofing, stain resistance and mold resistance. When choosing, you can pour a small amount of clean water onto the surface of the wall fabric. If the water droplets do not penetrate for a long time, it indicates that the waterproof performance meets the standard.
3. Details reveal quality
Density and color: High-quality wall fabric has tight warp and weft lines, and there is no obvious grid pattern when light passes through. It is washed twice before leaving the factory, with uniform color and no color difference.
Environmental protection certification: Choose products that have passed the China Environmental Label Certification (Ten-Ring Certification) or the EU SGS certification to ensure that the formaldehyde and VOC content comply with national standards.
Construction adaptability: Seamless wall fabric can achieve an entire wall without splicing, reducing the risk of water seepage through gaps. If you choose to use spliced wall fabric, it is necessary to confirm that the glue has strong weather resistance to avoid delamination during the rainy season.
Secrets for Wall Fabric Maintenance during the rainy Season
Even if moisture-proof wall fabric is chosen, daily maintenance still cannot be ignored. Here are some practical tips for maintaining wall coverings during the rainy season to help you extend the lifespan of your wall coverings and keep your home clean and tidy!
Daily cleaning: Be gentle to avoid damage
During the rainy season, dust tends to adhere to the damp surface of the wall fabric. It is necessary to gently brush it off with a feather duster or microfiber cloth every week to remove the dust.
If there are stains, the cleaning method should be selected according to the material: for synthetic fiber wall fabrics, neutral detergent mixed with warm water can be used for wiping, while for pure cotton wall fabrics, a special cleaner should be used to prevent fading. The flocked wall fabric should be cleaned with a vacuum cleaner's soft-bristled brush head to prevent the fluff from falling over.
Mold spot treatment: Phased response and scientific sterilization
Initial mold spots: Gently brush the surface mold stains with an old toothbrush, then wipe with a soft cloth moistened with 75% alcohol. After the alcohol evaporates, it can take away the moisture and kill bacteria.
Moderate mold spots: Mix bleach powder and water in a ratio of 1:10, pour it into a spray bottle and spray it on the mold spots. After 10 minutes, wipe it clean with a damp cloth. Pay attention to ventilation and wear a mask.
Severe mold spots: If mold spots penetrate to the bottom layer of the wall fabric, the wall fabric should be torn off, the base layer of the wall to the cement layer should be removed, and then waterproof coating and base film should be reapplied before attaching new fabric.
Preventive maintenance: Low cost and high efficiency
Desiccant assistance: Place moisture-absorbing boxes in damp areas such as cloakrooms and bathrooms. The boxes contain calcium chloride particles and can continuously absorb moisture for three months.
Regular maintenance of air conditioners: Clean the air conditioner filter before the rainy season to prevent dust from clogging and affecting the dehumidification effect. Run the "self-cleaning" function once a month to prevent mold from growing in the evaporator.
Green plant matching: Place shade-tolerant plants such as snake plant and turtle-back bamboo in the living room and bedroom. Their leaves can absorb some moisture in the air and release oxygen at the same time, improving the indoor microclimate.
