SonaSpray fcx
fcx is designed to visually complement the SonaSpray range of products. There are occasions when the specifier requires a flat smoother finish, fcx achieves this. Finish with performance.
fcx is applied in thin layers of 7mm per layer trowelled and compressing the material to 5mm thick.
Subsequent layers can be applied immediately to the material, (does not have to be left to dry), significantly reducing site times compared to other products that are applied in layers.
The two fcx options of finish are:
| fcx spray finish |
– fine texture |
| fcx trowelled finish |
– flat with lightly pitted surface |
Typical applications; Restaurants, conference rooms, reception areas etc. Consult Oscar Acoustics technical literature for details. Oscar Acoustics can also advise with design and specification and it is recommended that they are consulted early in the design process.

Survey: Carry out before installation commences.
Preparation:
Clips, hangers, supports and associated type attachments are to be placed by others prior to spray application.
Ducts, piping and other suspended items to be installed after fcx application or consult contractor.
Pattresses to be installed for light fittings / smoke sensors etc prior to fcx application to allow firm fixing for the fitting.
Pattresses to be made from plasterboard or wood not MDF which can stain the material when wet.
Wood pattresses to be fully painted to prevent any staining of material from contaminents.
Pattresses to be slightly smaller than the base of the fitting to ensure the fitting covers the pattress which should not be seen.
Pattresses to be the same thickness as the fcx, the contractor to spray to the edge of the pattress and brush clean the face.
A finishing edge will be required for the fcx where it does not occur naturally eg. around an opening for services to pass through a ceiling or around a staircase opening. Consult the contractor.
The surface to be sprayed shall be inspected prior to application to determine if priming/sealing is required to ensure bond and/or to prevent discolouration by migratory stains. Prime seal accordingly, consult contractor.
The contractor must install as necessary protection to other finished surfaces from overspray.
The manufacturer recommends 8 air changes per hour immediately after spraying for best drying conditions. Where this does not occur naturally, introduce fans and open windows. Consult contractor.
