Can you paint a mouldy bathroom ceiling?
Never paint over mould without cleaning it, as this won’t fix the problem. Instead, follow the steps outlined in this guide, including cleaning the area using sugar soap and sanding down any old, flaking paint. Once the ceiling is clean and dry, you can apply a mould-resistant primer or waterproof paint, which should help prevent mould from returning. In addition, ensure your bathroom is well-ventilated with an extractor fan or windows to reduce the risk of mould.
