Mould remediation involves the systematic identification, removal and post-treatment of mould infestation on walls, ceilings and other building surfaces. The root cause, typically moisture from condensation, structural damage or inadequate ventilation, must first be resolved. Affected plaster or wallpaper is removed and disposed of properly. After biocidal pre-treatment, the substrate is dried and treated with specialist anti-mould primers. Final coatings with fungal-inhibiting wall paints prevent re-infestation. Painting professionals must wear appropriate personal protective equipment and comply with applicable occupational health and disposal regulations. Documentation of the remediation process is strongly recommended.
