Moisture control

In detail

Moisture control means lowering the humidity and drying the wet surfaces that let biological growth establish, and the mould authorities treat it as the primary method rather than as prevention offered after the fact. The environmental regulator's position is that the moisture problem must be corrected or growth returns, and that removing what is visible without addressing moisture is not a solution. A state health department frames control of indoor humidity and prompt drying of wet materials as the measures that prevent growth. The measures are unglamorous and specific: ventilate during and after showering and cooking, dry wet surfaces rather than leaving them, keep furniture off cold external walls so air can move behind it, deal with condensation on the coldest surfaces first because that is where growth starts, and fix the leak. Where a room cannot be ventilated adequately, mechanical dehumidification does the same job. The same method matters after any wet cleaning: a soft surface that dries slowly develops odour and brown wicking marks, and airflow decides that more than product does.

What works

• Moisture control is effective against Mould Strongly supported

• Moisture control is effective against Mildew Strongly supported

• Moisture control is effective against Mould fungi Strongly supported

  It denies the spores the water they need to germinate. It does not kill them, and the source says so in the same document.

Why

• Moisture control is explained by Moisture control and recurrence
