Oscar Elite smooth synthetic acoustic plaster finish with the appearance of conventional painted plaster
Unlike plaster, this synthetic acoustic plaster absorbs sound energy instead of reflecting it, thereby reducing reverberation times and overall noise levels, giving clarity to speech and music.
A beautiful room with simple surfaces such as feature wood floors and plain flat walls may be visually appealing but may not be the most pleasurable place to spend time due to poor acoustics.
The same visual impact combined with a sympathetic and relaxing acoustic ambience is possible with Oscar Elite synthetic acoustic plaster.
Interior designers who incorporate Oscar Elite acoustic plaster into their designs can achieve spatial design with hard smooth surfaces without compromising the acoustic ambience.
This was the case with the Holland Park Grand Designs house in London. During refurbishment, Oscar Elite acoustic plaster was applied to the ceiling and inside of the lightwell, resulting in superb acoustics without compromising the beautiful, flat and smooth surfaces.
- Oscar Elite acoustic plaster can be directly applied to most substrates such as wood, gypsum board, concrete.
- Oscar Elite installations are applied at 27mm thick; the area is dependent on the acoustical requirements of the project. An air gap is introduced to achieve high absorption at low frequencies.
- Oscar Elite acoustic plaster is fire rated BS476: Class 1 to Part 7 and Class 0 to part 6.

59 Wells Street, Ottolenghi's newest restaurant in Fitzrovia, London
Ottolenghi have a reputation for taking the acoustics within their restaurants extremely seriously, with an Oscar Elite acoustic plaster ceiling in Nopi, Warwick Street, a SonaSpray acoustic spray ceiling in Ottolenghi Spitalfields and now an Oscar Elite acoustic plaster ceiling in the stunning new restaurant Rovi, Well Street.
The brief was to absorb just enough sound so as to leave an atmospheric buzz but ensure easy conversations across a table. Oscar Acoustics create an acoustic model that shows the theoretical reverberation time of the building without treatment. Oscars’ acoustic products are then added to the acoustic model until the desired effect is achieved; this helps to avoid the chances of overkill which could make customers feel self-conscious and uneasy, or not enough acoustic plaster absorption which can lead to high noise levels and customers who can’t wait to leave. Both of these would obviously have a negative effect on business but once Oscar Elite acoustic plaster was applied to the ceiling it achieved brilliant results, contributing to the overall perfect ambience of this beautiful restaurant.

45 Jermyn St
A destination restaurant in the heart of St. James's. An exquisite dining room and bar, inspired by the golden age of glamour.
With Martin Brudnizki Design Studio wanting to re-imagine Fortnum & Mason’s original Fountain Restaurant with design that fused the heritage of the iconic department store with the glamour of contemporary London, acoustics would have to be dealt with using cutting edge acoustic plaster technology so as to not compromise the design brief.
Oscar Elite acoustic plaster was specified by MBDS at a material depth of 27mm for being the smoothest acoustic plaster on the market, appearing as conventional painted acoustic plaster. The complicated shaped ceiling also took some clever detailing, drawing on the huge amount of experience of the Oscar Acoustics technical team. Oscar Elite acoustic plaster was used within all the ceiling shapes but with conventional painted plaster being used around the ceiling perimeter, a good colour match was essential. The difference was not visible and so the design concept remained as intended. Had conventional plaster been used, the restaurant would have been a sonic battle ground, often resulting in poor reviews. Oscar Elite acoustic plaster solved this challenging issue, leaving a calm a relaxing place in which the spend time and money.
Holborn Dining Room, Rosewood Hotel
Oscar Elite exceptionally smooth acoustic plaster applied to the ceiling in the beautiful Holborn Dining room at the Rosewood Hotel in London. This synthetic acoustic plaster absorbs sound energy instead of reflecting it, thereby reducing reverberation times and overall noise levels.
Oscar Elite acoustic plaster gives you clarity to speech and music and doesn’t compromise on design in a stylish venue.

NBS Product Specification
Oscar Elite Installation Structure
The 27mm construction consists of 2mm adhesive, 20mm thick mineral board, base and top coat Oscar Elite synthetic acoustic plaster totalling approximately 5mm, which is sprayed, trowelled and worked to optical requirements.
The finish is visually hard and firm to the touch but with excellent sound absorption. As with all acoustic plaster, installations should be suitably protected in areas where damage is likely.
Oscar Elite acoustic plaster is installed by our own in house, trained staff in order to guarantee optimal workmanship.
Maintenance & Cleaning
Dust is removed by lightly brushing or vacuuming with a soft brush head. It is also sometimes possible to blow dirt from the surface with a high pressure air hose. A wall or a ceiling can be entirely over sprayed in acoustic plaster in the same or a change of colour. Over painting must be done by spraying and not roller to prevent serious impact on the acoustic performance and damage to the product. Advice must be sought from Oscar Acoustics before painting as incorrect application can result in damage of the product.
Repairing & Servicing
A major benefit of our new Oscar Elite is its ability in most cases, to be locally and invisibly repaired, negating the need for expensive and inconvenient pre-handover resprays, as with many products similar in appearance. For more serious damage, it is possible for us to lightly sand and reapply the top coat.
Recessed services e.g. spot lighting will require a halo spacer to match the material depth. Oscar Acoustics manufacture and install stainless steel halo spacers (drawing available) to the same size as the hole cut out. Stop beads may be required around openings which again we can supply and install. Specially designed access hatches are also available through Profab, enabling the Oscar Elite to continue across the hatch door. Problems can arrise from using other hatches. These items are at extra cost and are to be purchased direct from the Profab. Please contact Oscar Acoustics for details and item code. Surface mounted fittings e.g. hanging/pendant lights will require pattresses to match the material depth. Please contact Oscar Acoustics for further advice.
Please Note: 90% of flangeless fittings do not work properly with any acoustic finish. If you are specifying a flangless fitting, please contact Oscar Acoustics for advice.
Our technical department offer free advice and acoustic calculations on the use of our products.
