Asbestos sheets, particularly those used for insulation or flooring, typically have a smoother, more consistent finish. You might observe small pinholes or a subtle gritty feel on the face of the cement, which are remnants of the manufacturing process where steam was used to create the fibre matrix.
Spotting the Difference: Key Visual Cues for Asbestos vs. Fibre Cement
Fibre cement, developed specifically to mimic these properties safely, generally entered the market as a direct replacement in the late 1980s and became standard in the 1990s. Never attempt to scrape, sand, or cut the material yourself for testing, as this action immediately puts you at risk of inhalation.
Fibre cement, by its nature, has a slightly more textured surface that resembles concrete. However, buildings constructed between the 1920s and the late 1980s may contain either legacy asbestos or early-generation fibre cement, making visual identification unreliable and requiring professional testing.

However, a closer inspection often reveals clues. If you suspect a material contains asbestos, you should assume it does until proven otherwise.
