If the substrate is wet or in a constantly immersed environment, polyurea will perform much better than polyurethanes. Many in the industry have been amazed by videos of polyurea being sprayed onto ice and water without affecting the reaction of the components. A properly prepared surface will improve adhesion, especially for critical applications such as damp concrete for lining and flooring, as well as protecting adhesion to geotextiles, timber, and steel. In these applications, polyurea systems will give the best results.
