Dampness in the home is a common problem that can have harmful consequences for health, comfort and the structure of the dwelling. Fortunately, there are natural and economical solutions to combat dampness and its undesirable effects. Here are a few tried-and-tested grandmotherly remedies.
What causes damp in the home?
Humidity in the home can have several causes:
- Condensation: this is the phenomenon that occurs when water vapor in the air turns into droplets on contact with a cold surface. Condensation is favored by poor ventilation, inadequate insulation or too low a temperature in the home. It manifests itself in the form of condensation on windows, mildew stains or musty smells. To combat dampness caused by condensation, it’s essential to provide good ventilation and improve insulation.
- Infiltration: this is caused by leaks in roofs, walls, windows or pipes. They cause damp stains, halos or efflorescence (whitish deposits) on the surfaces concerned.
- Capillary rise: caused by the absorption of water from the ground by walls in contact with it. They cause damage to the lower part of the walls, such as blisters, cracks or saltpetre (white crystals).
How can I tell if my home is suffering from damp?
It’s essential to detect the signs of damp in your home to take effective action and prevent more serious damage. Here are a few indicators that could help you determine whether your home is suffering from a damp problem:
- Dark stains or mold on walls or ceilings: These stains are often a sign of water infiltration or excessive condensation. They can appear in corners of rooms, around windows or on ceilings.
- Persistent musty odor: An unpleasant, persistent musty smell is a clear indicator of excess humidity. This smell can be particularly strong in basements, closets or poorly ventilated rooms.
- Peeling wallpaper: If you notice that your wallpaper is peeling or bubbling, it may be due to moisture seeping into the walls.
- Wood swelling or warping: Wooden doors, windows or furniture can swell, warp or crack due to humidity.
- Condensation on windows: Frequent condensation on windows, especially in winter, is a sign that indoor air is too humid.
- Unexplained allergies in the home: Humidity can encourage the growth of mold and dust mites, which can lead to allergies, irritation or respiratory problems.
If you notice any of these signs, it’s important to take steps to identify and resolve the moisture problem. Ignoring these signs can have harmful consequences for the health and structure of your home.
How do I make a home moisture absorber?
A humidity absorber is a device that reduces humidity in the air by capturing water in solid or liquid form. There are chemical moisture absorbers that can be bought commercially, but it’s also possible to make your own homemade moisture absorber with natural ingredients. Here’s how:
- Take a plastic or glass container with a perforated lid.
- Fill it with an absorbent product, such as coarse salt, baking soda, activated charcoal or silica gel (found in the anti-moisture sachets that come with some products).
- You can also use gum arabic, a natural material capable of absorbing moisture.
- Place the container in the room where you want to reduce humidity, such as the bathroom, kitchen or closet.
- Change the absorbent regularly when it becomes saturated with water.
6 grandmotherly remedies that really work against humidity
As well as making a homemade moisture absorber, here are some tried-and-tested grandmotherly tricks to combat dampness. You can use these 6 grandmotherly remedies to combat dampness and its consequences:
1. Baking soda: an excellent moisture absorber
Baking soda is a natural product with many virtues. In particular, it can be used to absorb moisture and eliminate unpleasant odours. Simply sprinkle baking soda on damp or mildewed surfaces, such as carpets, mattresses or furniture. Leave for a few hours, then vacuum or brush off the baking soda. Baking soda is an invaluable ally in the fight against dampness in your home.
2. Coarse salt absorbs humidity naturally
Coarse salt is another natural product that can absorb moisture from the air. Simply place bowls filled with coarse salt in damp areas of your home. The salt will attract water and gradually dissolve. So change the salt regularly.
3. Crushed clay to attract and absorb water
Crushed clay is an environmentally-friendly material that can be used to purify indoor air. Crushed clay is an effective natural remedy for absorbing moisture. It attracts and absorbs water, helping to reduce humidity. Simply place bowls or bags filled with crushed clay in damp rooms. The clay can be reused by drying in the sun.
4. Charcoal
Charcoal is a natural product that can absorb moisture and odors. Charcoal can be placed in containers or cloth bags in the bedroom to absorb moisture. Simply place pieces of charcoal in containers or cloth bags and arrange them in damp areas. Charcoal can be reactivated by heating it in the oven for one hour at 150°C.
5. Silica gel
Silica gel is a synthetic product often found in the anti-moisture sachets that accompany certain products, such as shoes or electronics. Silica gel can also help prevent wallpaper delamination by absorbing moisture. It can be used to absorb moisture in the home. Simply collect silica gel sachets and place them in damp areas. Silica gel can be regenerated by heating it in the microwave for a few minutes.
6. Cat litter and a large sock
Cat litter is a product that can absorb moisture thanks to its clay- or silica-based composition. To make a moisture absorber with cat litter, simply fill a large sock with litter and tie it at one end. Place the sock in damp places, such as the closet or car. Change the litter when the sock is damp. Cat litter is therefore a practical solution for combating dampness in small spaces.
Which plants absorb moisture in the home?
Some plants have the ability to absorb moisture in the home through their leaves or roots. These plants help combat humidity by absorbing excess water from the air. In this way, they help to purify indoor air and create a pleasant atmosphere. Here are a few examples of moisture-absorbing plants:
- Boston fern: a tropical plant that likes damp, shady spots. It absorbs moisture through its leaves and also eliminates certain pollutants, such as formaldehyde.
- Spathiphyllum: this elegant plant produces white, spathe-shaped flowers. It absorbs moisture through its roots and also removes benzene, toluene and xylene from the air.
- Dwarf palm: this exotic plant brings a touch of greenery to the home. Its leaves absorb moisture and filter out carbon monoxide, formaldehyde and xylene.
- Climbing ivy: a vigorous plant that can cling to a support or cascade down. Its leaves absorb moisture and purify the air of benzene, formaldehyde and trichloroethylene.
- Orchids: delicate plants with colorful, fragrant blooms. It absorbs moisture through its aerial roots and enhances the décor.
- Tillandsia: an original plant that needs no soil to grow. It absorbs moisture through its leaves and also feeds on elements in the air.
- Nepenthes: a carnivorous plant that produces urns filled with a digestive liquid. It absorbs moisture through its leaves and also traps unwanted insects.
- Cactus: a hardy plant that stores water in its spiny stems. It absorbs moisture through its spines and also regulates ambient temperature.
Daily aeration to prevent humidity
Daily ventilation is one of the best ways to prevent dampness in your home. Here are a few tips on how to air your home properly and maintain a healthy environment:
- Open windows and doors to let fresh air in: Air your home for at least 10 to 15 minutes a day, even in winter. This renews indoor air and reduces humidity.
- Use fans to renew the air: Extractor fans in the kitchen and bathroom are particularly effective at removing moisture generated by cooking and showering.
- Avoid drying clothes indoors: Drying clothes indoors considerably increases humidity levels. Use a tumble dryer or dry your clothes outside whenever possible.
- Use a dehumidifier to reduce ambient humidity: A dehumidifier can be very useful in rooms where humidity is particularly high, such as basements or bathrooms.
- Clean appliance filters regularly: Filters on air conditioners, fans and dehumidifiers need to be cleaned regularly to prevent dust and moisture build-up, which can reduce their efficiency.
By following these tips, you can help prevent humidity in your home and create a healthy, comfortable environment for you and your family. Good ventilation not only helps combat dampness, but also improves indoor air quality, which is good for everyone’s health.
