Acospray DC2 2.0
The same material as DC2 1.0, pressed as it is applied. That gives a structured surface that reads flat from the floor — the closest a sprayed finish gets to plasterboard — in a thinner build that protects ceiling height.

When to specify it
Specify it on a refurbishment where the floor-to-ceiling height cannot be given away.
- Interiors where the ceiling must read flat
- Reception, boardroom and gallery
- Restricted floor-to-ceiling height
- Refurbishment over existing flat soffits
- Swimming halls and semi-outdoor soffits — also hygroscopic

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.
