Mould Structural Cleaning Procedures

A Cleaning method should be chosen with the aim of producing the least amount of dust possible to limit worker exposure. More than one method may be necessary. Old buildings potentially contain lead based paints and should be properly assessed and remediated only by personnel specially trained in hazardous material handling.

Air Based Methods;

Air based methods physically remove contamination by vacuuming surfaces off to dislodge contaminants and include HEPA filter vacuum cleaning; air washing; laminar-flow; and down draft cleaning tables.

Liquid Based Methods;

Liquid based methods use water combined with the mechanical action of cleaning and include damp-wiping with a detergent, vinegar solution or alcohol solution; ultrasonic cleaning; steam cleaning; low pressure flushing and high pressure washing.

Remediation of Materials

Non-Porous and Semi Porous Materials;

Non-Porous materials and semi porous materials that are visibly mouldy should be able to be cleaned and reused.

Porous Materials;

Porous materials with mould damage to more than a small area (>1m2) should be removed and discarded. Materials that can be cleaned can be remediated if necessary. But should be discarded is possible. Porous materials that are remediated and returned to site should be dry and free of mould and with no remaining odour and should be periodically inspected to ensure the restoration was successful.

Odour Control;

Ozone or Hydroxyl treatment is used for odour control, then the item must first undergo restoration by drying and removing the mould growth with the recommended cleaning methods.
