Sonaspray K-13
The K-13 spray coating and application technology have been developed by International Cellulose Corporation (USA). Its main component is coarse cellulose flakes (up to 4 mm), which, using special equipment, mixed with adhesive, are applied to the treated surface. High adhesion allows spraying the coating on any type of surface, regardless of its shape and composition. The texture of the finished coating resembles rough cast. Request PriceScope of Application
SONASPRAY K-13 coating is used for acoustic treatment of rooms with large areas and internal volumes, including sports and entertainment complexes, production facilities with high noise levels, clubs, discos and other entertainment facilities, as well as stadiums, fitness centers, stations, airports, water parks, swimming pools, etc.
Composition
Cellulose, polyvinyl acetate adhesive, additives, dyes.
Distinctive features
- The coating is applied to surface of any shape and height;
- High spraying performance;
- Flakes of any RAL color from the manufacturer’s factory on request;
- Heat-insulating and anticorrosive properties, not subject to decay.
Coating thickness
From 15 mm to 70 mm. The thicker the layer, the higher the sound-absorbing properties.Standard colors
White (Off-White)
Other surface colors on request.

K13 multifunctional acoustic coating can be sprayed on metal profiled sheet ceilings, on concrete floor slabs, on drywall ceilings (as well as beams, trusses, crossbars, etc.)
The coating is applied ONLY using special RANGER equipment by a specialist who has completed a training course and has an appropriate certificate.
Details of this type of work should be clarified in advance.
The thicker the layer, the higher the sound-absorbing properties.
