Pacific Urethanes is bringing the PDA-aligned Globally Certified Polyurea Applicator Level 1 Training Program to Australia in May 2026.

No matter how long you have been in the industry, NEVER stop learning, and always follow industry guidelines and standards.

While attending the recent ACA 2025 Conference (Australasian Corrosion Association) in Melbourne, Australia last November, attended some excellent presentations. One in particular caught my attention and relates to why we coat concrete for waste-water application work for example with polyurea systems, as a barrier coating system. The following graphic shows the effect of pH (mainly acidic) exposure of concrete, and how much concrete surface can be lost over time.

For example, a 1% solution of Sulfuric Acid (common in waste-water work) has a pH of 1.0. And a 10% solution of Hydrochloric Acid has a pH ~0.8. Overcoating concrete that is acidic, and not properly neutralizing, can lead to further deterioration of the concrete under the applied coating system.
