Prevent Dampness and Mildew on Your Floors

– Place quicklime in buckets around the corners of the room. Quicklime absorbs moisture, keeping the room dry.

– If your floor is only slightly sweaty, you can use charcoal as an alternative. After use, sun-dry the charcoal and reuse it next time.

– For areas with mild mold, use a dry cloth to rub it off.

How to Prevent Dampness on Your Walls

– When your walls are considerably damp, the usual method is to apply concrete to the affected area. However, this is only a temporary solution, as prolonged rain will cause water to seep through the walls again, leading to unpleasant dampness and mildew.

– We recommend a method called “cutting off the water channel”: Create a small groove at the base of the damp wall. Apply a layer of root lacquer (a mixture of special cement, sand, and water) to the groove. Once the lacquer dries, you can apply lime or paint over the affected area.

– Root lacquer is made with special cement and fine sand. When it comes into contact with water or moisture, it continues to expand, creating a seal in the wall’s crevices, preventing water infiltration.

– If you are unfamiliar with construction materials, it is best to seek the help of professional builders to ensure a perfect waterproof wall.

For small areas, you can use vent blocks to improve ventilation and prevent musty odors caused by rainwater infiltration.

The effectiveness of waterproofing depends on the amount of water that has penetrated the wall and the location of the mildew. If the mildew has been there for a long time, remove the moldy paint and apply lime to absorb moisture before waterproofing. It is advisable to consult with builders from the outset to maintain your home in the best possible condition.

Frequently asked questions

You can take several measures to prevent damp and mildew. Ensure your home is well-ventilated, especially in areas prone to moisture, such as the kitchen and bathroom. Use exhaust fans or open windows to promote airflow. Keep an eye on potential problem areas, such as leaks or condensation, and fix them promptly. Consider using dehumidifiers to reduce moisture levels, and maintain a regular cleaning routine, wiping down walls and floors with mild detergent and water to remove any mold or mildew spores.

Post-storm dampness can be mitigated by taking swift action. Open doors and windows to allow fresh air to circulate and speed up the drying process. Use fans to aid in ventilation and consider renting industrial-strength fans for severe cases. If possible, remove wet carpets and upholstery, and dry them outdoors or with the aid of fans. Dehumidifiers are also useful in reducing moisture levels and preventing the growth of mildew.

To remove mildew, create a solution of one part bleach to four parts water. Apply this solution to the affected areas using a spray bottle or a cloth. Allow it to sit for 15 minutes, then scrub the area gently with a soft-bristled brush or a damp cloth. Rinse the area with clean water and wipe it dry. Ensure the room is well-ventilated during this process.

Long-term solutions include ensuring your home has proper insulation and vapor barriers. Check for any gaps or cracks in the walls, floors, or ceilings, and seal them with appropriate materials. Install or upgrade your exhaust fans to improve ventilation, and consider using moisture-resistant materials for areas prone to dampness, such as the bathroom or basement.

Damp and mildew can pose health risks, including respiratory problems such as asthma and allergies. They can also lead to the growth of toxic mold, which can cause more severe health issues. It is important to address dampness and mildew promptly to maintain a healthy living environment.
