Everyone knows today that asbestos is dangerous, but because it looks really dirty and messy once mould grows on it, people are still tempted to tamper with it, often without the right gear or skills to do so.
Never paint asbestos roofs to cover up mould because the mould will keep growing under the paint and break through within a short time. The only really successful way to paint asbestos sheeting is to first of all use chemicals that are toxic or pressure-clean it with water to return it to it's original state. This is highly illegal in Brisbane, and in my opinion, this is the way it should be.
When asbestos is pressure-cleaned asbestos fibres are spread all over the neighbourhood, which greatly increases the chance of people getting mesothelioma, a deadly and aggressive type of cancer affecting the lungs and abdomen.
Sadly, before this was known, it was common for people to pressure-clean their asbestos roofs and little kids often thought that it was snowing, because there was so much asbestos floating around that it gave the area a winter-snow-like flavour.
You can cut corners safely in lots of activities, but you should never cut corners when it comes to safety with asbestos. Instead, use a fully licensed team of people to remove your asbestos.
