Mould plays an important role in the natural environment as a break-down mechanism for dead organic matter. In the built environment it is an unwanted presence and a particular problem in the warm and humid conditions experienced in much of Australia. Unpleasant and unsightly, it can damage fabric and equipment and is a threat to the health of occupants

March 12, 2024 in Advisory Notes
