4. Would the owner consider changing material from K-13 to SonaSpray “fc” both are mfg by International Cellulose Corp. The SonaSpray provides a smoother more attractive appearance.

They also have a product called FKC that is between the K-13 & SonaSpray in appearance. We installed this product in a custom light blue color in the lobby dome of the Virginia Science Museum Richmond VA and also the exhibit hall where they hung a “Black Bird” jet.

See 09 83 16 Spray-Applied Acoustical Finish 2.02/A. Change Basis of Design to KFC by International Cellulose Company. An insulating value is required for the coating. K-13 provides an R value, SonaSpray is an acoustical coating. The manufacturer describes KFC as K-13 with a finer grind of materials to provide a smoother coat, with the same performance characteristics.
