The rapid pace of development of improved liquid-applied materials and finishes has given Building Teams new options. These sprayable, paintable, or “gunnable” products can add performance and sustainability benefits and reach new levels of resiliency and durability. Architectural finishes from the paints, coatings, and sealants developed with nano-enhanced substances include site- and factory-applied coatings for structural concrete, steel, metal panels, aluminum frames, and other specialty metals.
Fortified with nanoparticles, these assemblies are often stronger, more durable, more resistant to fire, and easier to clean than traditional product, according to the science blog Nanowerk (www.nanowerk.com). Some formulas with low or zero volatile organic compound (VOC) content have proven to be more resilient and stronger than their predecessors. In the case of masonry and concrete, the substances improve flowability and compacting--traits that improve the application of sealers and decorative finishes.
After reading this article, you should be able to:
- Discuss the key issues related to coating, paint, and sealant specification, including sustainability and air quality considerations.
- Describe how green standards, guide specifications and life cycle assessments, and environmental product declarations are used in the context of paint and coating selection and application.
- List typical substrates for coatings, such as concrete and metal, and the key correlated considerations for coating selection.
- Explain why in some circumstances it may be better for coatings and paints to be applied in the shop–and in some cases, why the materials might be better treated with anodizing or with no coating at all.

Paints and coatings: The latest trends in sustainability
When it comes to durability, a 50-year building design ideally should include 50-year coatings. Many building products consume substantial amounts of energy, water, and petrochemicals during manufacture, but they can make up for it in the operations phase. The same should be expected from architectural coatings.
