Mould growth on walls is common in humid environments, leading to health risks and structural damage. If left untreated, these can cause respiratory problems and persistent discoloration of walls. Understanding how to get rid of mould on walls is crucial for maintaining a safe and clean home. This guide outlines the best methods for how to remove mould from walls, prevent regrowth, and ensure a long-term solution for a mould-free space.
Identify the Cause of Mould Growth
Before tackling mould removal, it is essential to identify the root cause. Mould thrives in damp and poorly ventilated areas. Common causes include leaks, condensation, and high humidity levels. If the mould is recurring, inspect for underlying moisture issues such as plumbing leaks or inadequate ventilation. Addressing these problems first will prevent mould from returning after cleaning.
Check for discoloration of walls, musty odours, or dark patches, which indicate active mould colonies. Areas prone to mould include bathrooms, kitchens, basements, and rooms with poor air circulation. Once the cause is identified, take steps to reduce moisture levels by improving airflow, using dehumidifiers, or fixing leaks.
Gather the Right Cleaning Supplies
To know how to eliminate mould, having the right cleaning supplies is essential. Protective gear such as gloves, goggles, and a mask prevents direct exposure to mould spores, reducing health risks. For cleaning solutions, white vinegar is a natural antifungal agent effective against mild mould growth, while hydrogen peroxide (3%) acts as a strong disinfectant to kill spores. Baking soda helps absorb moisture and neutralise odours, making it useful for preventing regrowth. In cases of severe infestations, a diluted bleach solution can be used on non-porous surfaces. Ensure to handle this with caution due to its strong chemical properties.
Using the right tools is equally important to prevent spreading spores. A scrub brush or sponge allows for thorough removal, while microfibre cloths help wipe away residue without scattering mould particles. Ensuring proper ventilation while cleaning will also aid in drying the affected area, minimising moisture accumulation that can lead to further growth.
Step-by-Step Mould Removal Process
Step 1: Prepare the Area
Before starting, ensure proper ventilation by opening windows and using fans. Cover nearby furniture or flooring to prevent contamination.
Step 2: Apply the Cleaning Solution
A natural approach involves mixing vinegar and water, spraying it onto the affected area, and letting it sit. Hydrogen peroxide or a diluted bleach solution (one part bleach to ten parts water) can be more effective for stubborn mould. Allow the solution to sit for 10–15 minutes to break down mould spores before scrubbing the surface.
Step 3: Scrub the Mould Off
Use a scrub brush or sponge to remove the mould, applying firm pressure on affected areas. To fully remove residue, wipe the area with a damp cloth. This prevents potential growth of mildew on walls.
Step 4: Dry the Area Completely
Moisture encourages mould regrowth. Use a dry cloth or fan to speed up the drying process and ensure the area remains moisture-free.
Preventing Future Mould Growth
Once you remove mould from walls, taking preventive measures is crucial to reduce the chances of recurrence. Improving ventilation helps maintain airflow and prevents moisture buildup, making it essential to keep windows open or use exhaust fans in high-humidity areas. Controlling humidity levels is another key step—using dehumidifiers or air conditioners can help maintain indoor humidity below 50%, reducing the conditions that allow mould to thrive.
Addressing moisture sources is equally important. Immediately fixing leaks, whether from the roof, plumbing, or condensation, prevents excess moisture from seeping into walls, which is ideal for mould growth. Applying mould-resistant paint adds an extra layer of protection, helping to prevent spores from settling on walls. Regular inspections and prompt action on any signs of moisture problems will ensure your home remains mould-free in the long term.
Conclusion
Understanding how to get rid of mould on walls is key to maintaining a healthy home. Addressing moisture issues, using proper cleaning methods, and taking preventive measures help eliminate mould and stop regrowth. Regular humidity control ensures long-term protection against mildew on walls, keeping surfaces clean and free from discoloration.
