When powder coatings were first introduced into the architectural market for metal surfaces, they were heralded as a vastly superior product and expected to quickly replace liquid paint and anodization. However, paint has had more staying power than predicted. To understand what attributes of liquid paint are causing it to remain popular, it is important to take a look a broad range of considerations, including color options, cost, ease of use and performance.

Elastomeric wall coatings (EWCs) are often used to waterproof porous cladding, both in new construction and as a solution for failed weather barriers. Since they are more expensive than paint, it is important to achieve maximum service life. Durability of coatings is usually considered as a function of weathering resistance, but EWCs may fail due to an inability to bridge cracks that often form in cold weather. Unfortunately, there are no industry standards for this important parameter. To fill this void, an economical and practical test method was developed by the authors.
