What Is Mould \u2014 and Why Does It Happen?<\/h2>\n\n\n\n
Mould is a type of fungus. It thrives in environments where moisture, warmth, and nutrients<\/strong> are present, which makes homes an ideal breeding ground when something goes wrong.<\/p>\n\n\n\n While mould is certainly unsightly, it\u2019s not just an aesthetic issue. Prolonged exposure can contribute to respiratory problems, allergies, and asthma<\/strong>, particularly in children, older people, and those with existing health conditions.<\/p>\n\n\n\n Resident behaviours, such as drying laundry on radiators, and spikes in the temperature of the heating, can cause condensation and exacerbate moisture issues, but the root cause is often building-related. <\/p>\n\n\n\n Painting over mould without addressing the cause is one of the most common and costly mistakes.<\/p>\n\n\n\n Paint does not<\/strong> fix moisture. At best, it temporarily hides staining. At worst, it traps moisture and allows mould to grow back underneath, often spreading further.<\/p>\n\n\n\n Without these steps, mould will return, no matter how many coats of paint you apply.<\/p>\n\n\n\n Fixing mould properly isn\u2019t complicated, but it does need to be done in the right order.<\/p>\n\n\n\n Is it condensation, a leak, or rising damp? Treating mould without understanding this step guarantees failure.<\/p>\n\n\n\n Repair leaks, improve ventilation, or address insulation gaps.<\/p>\n\n\n\n Visible mould must be treated with a proper mould cleaner or killer to remove spores, not just wiped away.<\/p>\n\n\n\n Once clean and dry, surfaces should be primed and finished with specialist products designed to resist future mould growth.<\/p>\n\n\n\n Specialist paint products are effective once you have addressed the cause of mould.<\/p>\n\n\n\n Here’s a step by step approach to using a paint system:<\/p>\n\n\n\n Yes – absolutely. Painting over mould leaves spores behind, and the mould will return.<\/p>\n\n\n\n In England, damp and mould are no longer issues landlords can ignore.<\/p>\n\n\n\n Awaab\u2019s Law<\/strong>, which came into force on 27 October 2025<\/strong>, was introduced following the tragic death of two-year-old Awaab Ishak due to prolonged mould exposure.<\/p>\n\n\n\n This law introduces clear accountability and enforceable timelines, particularly in social housing.<\/p>\n\n\n\n Some of the most frequent issues professionals see include:<\/p>\n\n\n\n Ventilating rooms, running a dehumidifier, moving furniture away from walls, and keeping your heating on a constant temperature can help, but these are not substitutes for proper repair.<\/p>\n\n\n\n Mould isn\u2019t just something to paint over – it\u2019s a warning sign.<\/p>\n\n\n\n The right approach is always the same:<\/strong><\/p>\n\n\n\n Good landlords who maintain safe, healthy homes deserve credit – and clear rules now help protect tenants from dangerous living conditions.<\/p>\n\n\n\n Call our experts on \n\n01303 477555<\/a><\/p>\n\n\n\nCommon causes of mould include:<\/h3>\n\n\n\n

\n\n\n\nThe Role of Specialist Paints<\/h2>\n\n\n\n
\n
Remove loose paint and dirt, and treat visible mould with a \n\nmould cleaner.<\/a>
You should not<\/strong><\/em> use bleach to clean away mould – it can increase humidity and does not contain an anti-fungicide.<\/li>\n\n\n\n
Use a dedicated \n\nmould killer<\/a> to deal with mould you can\u2019t see.<\/li>\n\n\n\n
Once dry, apply a suitable primer such as \n\nZinsser BIN<\/a> or \n\nZinsser B-I-N Aqua<\/a> to block stains and create a stable base.<\/li>\n\n\n\n
Finish with a mould-resistant product like \n\nZinsser Perma-White<\/a>, which contains fungicides to resist future growth. This paint – despite its name! – can be tinted to any colour, not just white, so think about how you would like your whole room to look.
Other recommended paints for mould treatment include \n\nRonseal 6 Year Anti Mould Paint<\/a> and \n\nCrown Ultra Matt+<\/a>.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/www.wood-finishes-direct.com\/blog\/wp-content\/uploads\/2026\/01\/mould-paints-blog-1024x512.png\")
