Maintenance advice on Spraycell® Thermocon sound-deadening spaying

For periodic maintenance of Spraycell® Thermocon acoustic ceiling, here are some important guidelines.

  • The frequency of maintenance depends on the degree of pollution and the use of space.
  • Spraycell® Thermocon is antistatic. This means that dust and dirt deposition will normally be minimal. However, air flows
must be avoided which constantly blow dirt and dust against the ceiling, e.g. by air conditioning or rising air above radiators.
  • Local damage, large or small, which also arises for whatever reason, can also be repaired by us locally.
For older installations, a small color difference may possibly occur. In all cases, the remaining (undamaged part)
of the ceiling can be sprayed with new thin Spraycell® Thermocon to obtain a total unit of color.
  • Under certain circumstances and depending on the degree of contamination, the ceiling surface can be sprayed
with our Sonacolor®, a water-based paint product, while maintaining the acoustic values.
  • Asona-Asia is at your disposal for advice in such situations.




  • Asona-Asia guarantees the adhesion of Spraycell® Thermocon construction on a clean and dry building surface.


  • The guarantee also applies to the sound-absorbing effect of the Spraycell® Thermocon ceiling, subject to the fact that
the ceiling surface has not undergone any incompetent further treatments by third parties after completion.


  • These guarantees apply for the duration of 5 years after delivery.


  • Guarantees are only valid when all invoices for delivery and installation of Spraycell® Thermocon construction have been fully met.
