For those of you that have been interested in the PDA - The Association for High Performance Elastomeric Technologies applicator school, but outside the "Americas," well this is coming up in Australia in May, to serve that area as well as SE Asia.

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.

Just back from a great PDA 25th Anniversary Conference, Demo Days and applicator training session. If you missed it, well…. PDA - The Association for High Performance Elastomeric Technologies

Received this issue and this is what happens when one uses the incorrect material to improperly flush equipment, then improper shut-down and storage. This is especially true with the ISO side with polyurea spray systems. At first, the polyurea material being used was blamed, then went on to blame the spray hose system using. Follow the manufacturer’s recommendations and industry guidelines, NOT the various cheap, incorrect suggestions found on social media. Just because someone else did it does not make it right….
