Application

Acoustic plaster ideal for use in offices, hotels, receptions, luxury homes, restaurants and high specification apartments and houses where the designers' desire for hard flat surfaces can lead to noise reverberation problems.

Acoustic plasters are not suitable for walls below 2 m from the floor. Spray and trowel application by Oscar Acoustics trained in-house teams.

Description

An exceptionally smooth, flat acoustic plaster finish with the appearance of conventional plaster.

27 mm thick decorative, highly sound-absorbent ceiling and wall covering with either a stucco or plaster smooth finish, installed by Oscar Acoustic Elite teams.

Oscar Elite acoustic plaster can be applied directly onto plasterboard, smooth concrete, steel sheet and most other surfaces and is suitable for flat, domed and vaulted soffits.

An excellent alternative to acoustic panel ceilings without design compromise.

Features and benefits:

Acoustic spray controls sound reverberation in buildings by absorbing sound energy instead of reflecting it, thereby reducing reverberation times and overall noise levels, giving clarity to speech and music.

It can be applied directly onto plasterboard, smooth concrete, steel sheet and most other surfaces.

Suitable for flat, domed and vaulted soffits.

Available in two surface finishes and a variety of colours.

The standard white acoustic plaster finish provides a light reflectivity of 94%.

Acoustic spray is easy to maintain through vacuuming or dusting.

Can be over-sprayed in a different colour if required.

Application:

Acoustic plasters are not suitable for walls below 2 m from the floor. Spray and trowel application by Oscar Acoustics trained in-house teams.
