Maintenance / aftercare

Cleaning and maintenance guide.

To ensure continual high performance of our acoustic seamless ceiling system the following regime should be followed.

  1. Keep the area in and around the ceiling dust free.
  2. Reduce draft flow as this can cause dust to be forced into the ceiling.
  3. Vacuum every six months.
  4. Report and observe any colour changes due to air pollution.
  5. Keep air conditioning units clean and serviced.
