Sonaspray K13
Sonaspray K13
The K-13 spray coating and its application technology were developed by the American company ICC (International Cellulose Corporation). Its main component is coarse cellulose flakes (5-10 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 texture of the resulting coating resembles a “fur coat” plaster finish.
Application area: SONASPRAY-K13 coating is used for acoustic treatment of large areas and interior volumes, including: sports and entertainment complexes, industrial premises with high noise levels, clubs, discos and other entertainment facilities, as well as stadiums, fitness centers, train stations, airports, water parks, swimming pools, etc.
Compound
Cellulose, polyvinyl acetate glue, additives, dyes
Distinctive features
- The coating can be applied to any surface without restrictions on its shape and height;
- High spraying performance;
- It is possible to order flakes of any color from the RAL catalog.
- It has thermal insulation and anti-corrosion properties and is not subject to decay.
Coating thickness
From 15 mm to 70 mm. The thicker the layer, the greater the sound absorption properties.
Standard colors
White
(Off-White)
The surface can be painted in other colors upon request (Black, Gray, Beige, Gold Yellow, RAL 1004*).
Description
Sound absorption coefficient
Acoustic testing was performed by order of ICC-Houston according to ASTM C-423 standard.

The K-13 multifunctional acoustic coating can be sprayed onto 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.
