Sonaspray FC
Sonaspray FC
The FC spray coating and its application technology were developed by the American company ICC (International Cellulose Corporation). Its main component is medium-sized cellulose flakes (3-5 mm), which are mixed with an adhesive binder using specialized equipment and applied to the surface to be treated. Its high adhesion allows the coating to be sprayed onto any type of surface, regardless of its shape or composition. The resulting coating has a texture reminiscent of a “fur coat” plaster finish.
Scope of application
The coating is used to reduce reverberation time and noise levels in public and entertainment spaces: offices, restaurants, clubs, bars, discos, water parks, swimming pools, etc. It can also be used in private interiors.
Compound
Cellulose, polyvinyl acetate glue, additives, dyes
Distinctive features
- The coating can be applied to any surface without restrictions on its shape and height;
- Improved sound absorption properties compared to Sonaspray K-13;
- Increased reflective properties;
- Ecologically safe – only organic components.
Coating thickness
From 15 mm to 25 mm. The thicker the layer, the greater the sound absorption properties.
Standard colors
Snow-white (Arctic white)

SONASPRAY FC spray-on acoustic coating can be applied to corrugated metal ceilings, concrete floor slabs, and plasterboard ceilings (as well as beams, trusses, joists, etc.). The coating is applied ONLY using specialized RANGER equipment by a trained and certified professional. Details regarding this type of work must be clarified in advance.
