Acoustic spraying

Improve the acoustics of your room with Acosorb acoustic sprays. By treating the ceiling and walls with our acoustic spray, sound is absorbed better, reducing reverberation and directly improving acoustics.

The acoustic spray is applied completely seamlessly. Due to the great diversity of structures, thicknesses and colours, the right mix can be put together for each project in line with the available budget.


  • Acoustic spray is the solution to problems with acoustics
  • Our specialists will apply the spray plaster seamlessly to your ceiling and/or walls in a single phase
  • The degree of sound absorption depends on the thickness. For a higher degree of sound absorption, we apply a thicker layer of Acosorb

Acosorb's services are regularly applied to new construction and renovation projects, as well as to existing situations. Together with architects and clients we look at how to optimally improve the acoustics.

Costs of acoustic spraying

The price of an acoustic spray ceiling varies per project. The costs depend on, among other things, the size, the structure of the room and any additional requirements. We are happy to tell you more about the costs involved. Please contact us or request a free quote.



Acoustic spraying is easy to maintain. For optimal cleaning, we recommend using a vacuum cleaner with a soft brush, for example. This will prevent damage to the wall or ceiling. We are happy to provide you with a complete maintenance instruction, please contact us.
