SonaSpray fcx and SonaSpray fc were specified for Londons new Hard Rock Hotel throughout the café and bar, providing a seamless and decorative acoustic solution. The spray absorbs excessive noise, creating a pleasant ambience by giving clarity to music and speech, transforming what would otherwise have been a cacophonous space.
A one coat, fire rated, decorative acoustic plaster finish with an attractive, flat and lightly pitted surface.
Acoustic plaster for stylish architectural designs
A visually beautiful room may not be a pleasurable place to spend time due to poor architectural acoustics. Hard, flat surfaces such as wooden floors and plastered walls reflect sound, thereby increasing and amplifying noise levels within the space, resulting in poor acoustics and sound quality.
SonaSpray fcx acoustic plaster is a one coat, acoustic decorative finish with an attractive, flat and lightly pitted surface for reverberation control in buildings. SonaSpray fcx acoustic plaster spray will conform to any surface shape, providing that the surface curvature will allow finishing with a trowel. The high performance adhesive will bond to virtually all common construction materials including plaster, wood, metal and concrete.
Note: Some surfaces such as water or tobacco stained ceilings, timber and oxidised metal will require sealing to prevent migratory staining into the SonaSpray fcx finish.
All our products significantly better the new fire requirement required under the updated Approved Document B.
Note: Always insist on obtaining a copy of the fire test report before using a product.
Its Class 0 to BS476 & B-s1,d0 fire rating provide significant benefits over the new Approved Document B requirements by providing little to no smoke and absolutely no droplets, assisting in the safe escape of occupants.

Seamless finishes from textured to plaster smooth
The standard acoustic plaster white finish can be spray painted to the chosen colour with a minimal effect on the sound absorption qualities of SonaSpray fcx and its ability to achieve great architectural acoustics. Bespoke colour materials are also available (minimum order quantities apply).
Ideal for use in offices, homes, swimming pools, public places, classrooms, restaurants and so much more.
We have independent acoustic test data for painted fcx which is available on request.
Future reconstruction of buildings may require removal of SonaSpray. It can be recycled or disposed of as a non-special waste. Your local authority environmental department will give advice on recycling.
What people say about our SonaSpray fcx acoustic spray installations...
"The architect's solution of fitting high level, sound absorbing panels produced a negligible improvement. We continued to battle'with intolerable echo'making the room unfit for its purpose.
Following an independent sound monitoring exercise, an alternative acoustic dampening application was recommended and Sonaspray fcx acoustic spray was selected. My caretaking staff were greatly impressed by the attention to detail paid by your engineers during the installation procedure. Every surface was carefully covered and the entire procedure was completed professionally .
The effect of the application has been tremendous! The hall is a different room and PE, assemblies and lunch-times have become pleasurable occasions compared to the sonic battleground we experienced previously."
Headteacher, Meadowside School, Gloucester
“Simply Awesome! It's created a totally different dining environment. Speech and music are clear and all background clutter noise has gone. The restaurant feels comfortable and somehow warmer and cosier.”

SonaSpray fcx acoustic plaster installations
Hide is a new 13,500 square feet, dramatic three-level, Michelin star HIDE restaurant and bar situated in Piccadilly, London. Our specialist in-house installation teams expertly applied SonaSpray fcx in two bespoke whites to feature curved ceilings on both the ground and first floors of the restaurant to create a relaxed and enjoyable dining experience for its guests.
Vajrasana is a bespoke Buddhist retreat centre situated in the picturesque Suffolk countryside. With such a project, reverberant spaces with high noise levels and unclear speech would not be appropriate so acoustic treatment was required throughout.
SonaSpray fcx acoustic plaster applied to ceiling in the seriously stylish Scarfes Bar in the Rosewood Hotel, Holborn to control reverberation for excellent restaurant and bar acoustics. It was then painted to create a stunning velvet effect.
Architects Macaulay Sinclair specified Oscar Acoustic's SonaSpray fcx for the upper walls of this fantastic new Dishoom Restaurant recently opened in Manchester.
We were specified to acoustically treat the boat exhibition halls and museum cafeteria area of this stunning museum to ensure that the acoustic ambience was fitting with the calming and beautiful surrounding views and would not steal any focus from the interior design or exhibitions on display.
Architects Macaulay Sinclair specified Oscar Acoustic's SonaSpray fcx acoustic spray plaster finish onto plasterboard at 12mm thick for the ceilings in the famous Dishoom restaurant in the heart of Kensington, London.
A large space like this project in the Colchester Visual Arts Centre would normally be extremely reverberant and noisy with its timber floor & minimal walls; but instead the feeling is more of a grand open space that is lined with plush carpets and soft furnishings after being treated with our SonaSpray fcx recycled, architectural, acoustic spray finish.
Hope Academy in Newton-Le-Willows was a BSF design and build project by Willmott Dixon. Outside acoustic consultation lead to Oscar Acoustics’ SonaSpray FCX being specified for the impressive giant feature, yellow pods in the main dining space, SonaSpray K-13 Special in light and dark grey for the auditorium walls and SonaPanel acoustic panels for the main sports hall upper walls.

SonaSpray fcx installations are tailored to meet your specific projects architectural acoustic needs. There is a choice of finish and acoustic performance. Special colours can be manufactured for larger installations or for most applications the standard white RAL9010 finish can be refinished with water based paint. SonaSpray fcx may be applied at variable thicknesses and areas to provide designed acoustic ambience. It is spray and trowel applied, building to the full thickness in one application.
SonaSpray fcx standard absorption coefficients
Acoustic testing has been carried out against concrete. Substrates likely to provide increased performance include plasterboard with the use of an air gap behind, rib deck or profiled metal sheet. Please contact Oscar Acoustics’ technical department for free design assistance.
Test DATA certified by TNO Technical University Delft NL. Tests were on a solid substrate. A panel substrate with air space behind the panel will change absorption; normally there is improved absorption at low frequency giving further flexibility in the design of architectural acoustics.
SonaSpray is excellent at thermally insulating by creating macroscopic air spaces between and within the cellulose fibres. U-Values can be adjusted to your projects exact requirements by adjusting the spray material depth. SonaSpray insulates by creating dead air spaces macroscopically between and within the hollow cellulose fibres.
Dry weight 4.50kg/m2 at 20mm thick.
Bonding to substrate
SonaSpray fcx can be applied to virtually any substrate; some surfaces may need priming to control suction. Old surfaces may need a barrier coating to prevent staining from leaching out of contaminants whilst the surface is wet. Fully cured SonaSpray fcx will not only improve the architectural acoustics but improve the strength of the substrate.
For indoor swimming pools SonaSpray fcx aids in condensation control. The proper combination of SonaSpray fcx and ventilation prevents condensation on metal, concrete and other surfaces. SonaSpray fcx actually reduces ventilation requirements, saving in both the ventilation equipment cost and operating costs.
SonaSpray fcx is a natural humidity moderator. At times of increasing humidity SonaSpray fcx will absorb large amounts of water vapour. When the humidity drops SonaSpray fcx will exhale water vapour and maintain a balance. This characteristic promotes a healthy atmosphere.
The adhesive used with SonaSpray provides a strong, durable and resilient bond. Fully cured SonaSpray can improve the composite strength.
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 SonaSpray to continue across the hatch door. Problems can arrise from using other hatches. These items are at extra cost and are to be purchsed 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.
Where to use
Any interior space requiring improved architectural acoustics; SonaSpray fcx can be quickly and effectively applied to most prepared surface and construction configurations helping to achieve minimum working down-time in existing structures, with abilities to meet critical deadlines in new construction. SonaSpray fcx trowelled finish has a durable, flat pitted surface and is suited to walls and ceilings in restaurants (see photos), offices, public buildings, hotels, shopping complexes, conference rooms, large domestic rooms and indoor pools.
