Coatings

For example, spray foam must be covered per code. Usually, drywall is typically the choice, but alternatives are available, such as spark-ignition paint and ThermoCon, which is an exposed-finish product consisting of specially milled cellulose fibers treated with fire retardant chemicals. We used ThermoCon at the House on the Rock, where it was dyed green to appear as grass or moss.

Another coating is polyurea. Polyurea protective coatings are commonly used for the following reasons:

• Abrasion Resistance
• Corrosion Protection
• Waterproofing
  
• Chemical, Environment or Atmospheric Resistance
• Decoration
• Structural Enhancement

Spray-on vapor retarders are usually used in a commercial applications at the request of architects. But all products can be used in both residential and commercial settings. For example, spark-ignition paint would be installed in a walk-up attic where foam is used on the roof deck.
