The paint achieved the Bushfire Attack Level (BAL) 40 standard which assesses the bushfire resistance of buildings and construction materials.
Professor Guan Yeoh, Director of the ARC Training Centre for Fire Retardant Materials and Safety Technologies at UNSW describes the paint as a “breakthrough: “It’s a paint that has satisfied the second highest fire rating, which means that it can protect houses.”
[...] Under heat the paint grows from a very thin layer to a very thick layer to protect the timber. After a wildfire some residue remains. “But you can see that the wood itself is actually not burnt at all,” says Yeoh. “Prep your surface again and then you repaint it.
