5Preventing Future Mould Growth
Preventive actions are essential after eliminating mould from walls. Controlling moisture and ventilation prevents mould growth. This article will help you keep your home mould-free by controlling moisture and preserving mould-free walls.
➜ Moisture Control and Ventilation in Rooms
Keep your home’s humidity under 50%. Dehumidify basements, bathrooms, and kitchens. Fix plumbing leaks quickly and ventilate these locations. Good airflow prevents mould formation. Bathroom and kitchen exhaust blowers remove moisture and steam.
Use fans and open windows to circulate the air. Trickle or air vents can increase ventilation in enclosed places. Cold surfaces can condense, allowing mould growth. Avoid condensation by insulating pipes, windows, and walls. Insulation with a moisture barrier prevents moisture from entering the walls.
Houseplants enhance humidity. To avoid excess moisture, water plants carefully and drain well. Put a tray under the pots to catch water.
Dry carpets, rugs, and upholstery immediately. To dry thoroughly, use a wet vacuum or extractor. Dry spills and wet garments or towels immediately.
➜ Tips for Maintaining Mould-Free Walls
Regular Cleaning: Clean your walls regularly to avoid dust, filth, and mould. Wipe the walls with a damp cloth or sponge in damp areas like bathrooms and kitchens.
Check for leaks: Check your walls for water stains, peeling paint, and bulging wallpaper. Fix leaks immediately to prevent mould growth.
Monitor Condensation: Look for condensation on windows, walls, and other surfaces. Remove the condensation and fix the cause, such as poor insulation or ventilation.
Proper Sealing: To avoid moisture entry, seal windows, doors, and wall openings. Seal cracks using weather-stripping and caulk.
Remove clutter: Clutter can block airflow and foster mould growth. Airflow and mould prevention are improved by organising and decluttering your living environment.
Maintain exterior drainage: check your gutters, downspouts, and drainage systems. Proper outside drainage prevents water from entering walls and generating moisture issues.
Monitor Indoor Humidity: Use a hygrometer to monitor indoor humidity. Dehumidifiers or ventilation can lower humidity above the required range.
