How to Remove Mould from Painted Walls: Effective & Safe Techniques

Mould on painted walls can compromise both appearance and indoor air quality, but removing it doesn’t have to be difficult. With the right tools and techniques, you can restore your walls safely and prevent recurrence.

Start by containing the affected area to prevent spore spread. Wear protective gear including gloves and a mask. Mix a solution of equal parts water and white vinegar or use a mild detergent with water. Apply gently with a soft brush or sponge, focusing on porous edges where mould thrives. Avoid abrasive scrubbing that can damage paint. Rinse thoroughly with clean water and allow walls to dry completely to inhibit regrowth.

Maintaining dry, well-ventilated spaces is key. Use dehumidifiers in damp areas and ensure proper airflow with fans or extractors. Regularly inspect walls for early signs of moisture or mould, especially in bathrooms, basements, and kitchens. Promptly repair leaks and clean surfaces to keep painted walls mould-free.

If mould covers large areas (>10 square feet) or persists despite DIY efforts, consult a professional. They can assess hidden moisture, safely remove contaminated layers, and recommend long-term solutions to protect your home’s integrity.

Removing mould from painted walls is a manageable task when approached with care and the right methods. By following these steps and maintaining proper home conditions, you can eliminate mould safely and keep your walls clean and healthy. For peace of mind, schedule regular checks and act quickly at the first sign of trouble.
