Mould before painting: why the surface should not simply be covered | SERV4U Blog
Decoration is not a mould treatment plan Visible mould should not simply be covered with fresh paint. The location, extent, moisture history, ventilation, leaks, condensation and any recent building work may all be relevant to deciding what should happen next. Record what is visible Useful information includes the affected room, wall or ceiling, when the mould appeared, whether it returns, whether there is a smell or condensation, and whether the area changes with weather or use. Clear photographs should show both the detail and the wider room context. Separate cleaning, investigation and decoration A suitable cleaning and preparation route, if agreed, is different from investigating the cause or carrying out remedial building work. The quotation should not present painting as a solution to an unresolved moisture source. When specialist input may be needed Persistent, widespread or unexplained mould may require a competent property or building specialist. SERV4U can discuss the visible issue and the practical next step, but the scope should be agreed before measurements, diagnosis or remedial work are promised. Next step: Send the location, history and photographs of the visible mould before requesting a painting quotation.
