Acoplaster F - Acosorb Acoustics
The smoothest surface in the range, and the only one that is not sprayed in mass. A 30 mm mineral-wool panel is bonded to the substrate and finished with a 2 mm plaster coat, so it reads as flat plaster and performs as an absorber.

The smoothest surface in the range, and the only one that is not sprayed in mass.
A 30 mm mineral-wool panel is bonded to the substrate and finished with a 2 mm plaster coat, so it reads as flat plaster and performs as an absorber.
- Specs
- Grain: Smooth, sanded
- Build: 35 mm system
3 mm plate adhesive + 30 mm mineral wool + 2 mm plaster - Absorption: NRC 0.90 at 32 mm — αw 0.95, ISO 11654 Class B
- Coverage: 7–8 kg/m² applied
- Colour: White. Any other colour by adding pigment to the plaster.
- Fire — Australia: Group Number not established for this system
AWTA 25-004810 covers the sprayed Acospray systems, not this one. Request a Group Number assessment where the project needs one - Fire — Europe: B-s2,d0
EN 13501-1 · Efectis 1350-1:2018 - Substrate: Clean, dry and airtight, primed with Acoprimer. Above 15 °C during application and while it cures.

Worth Knowing:
- Substrate flatness sets the flatness of the finished plane.
- Minor repairs by hand — spread material, sand back when dry.
- Airless spray only when painting. Never rolled.
- Moisture is monitored while it dries.
- Features
- 0.90 NRC at 32mm

- When to Specify it
Specify it when the ceiling has to look like a plastered ceiling and nothing else.
- Boardrooms and reception where the ceiling must read as plaster
- Galleries and museums
- Heritage interiors where a sprayed texture would be wrong
- Any brief that says “flat, white, and no visible system”
- Performance by Thickness
Absorption is a function of thickness.
Specify the thickness against the target, not the headline figure. Sound absorption coefficient by octave band, manufacturer-published.
