Would repainting an Armstrong mineral fibre or Orcal metal tile change its acoustic performance?
In terms of sound absorption there may be a small loss, depending upon the tile face pattern (fissures, perforations, scrim etc), the paint type used, and the thickness of the applied coat(s). It is unlikely that the ceiling’s sound reduction or attenuation performance will be adversly affected but if the spaces where the ceiling has to be repainted are acoustically critical, then laboratory testing to assess any possible differences in acoustic performance should be conducted on repainted samples. It should be noted that the repainting of ceiling tiles could also adversly affect their other technical performance factors such as fire reaction, sag, light reflectance etc and the implication of such possible changes needs to be considered. Finally it should be appreciated that the repainting of any tiles supplied by Armstrong will invalidate any warranty that was provided when the tiles were new.
