BASWA Acoustic Plaster spray Casual

BASWA Casual | Seamless Acoustic Spray Plaster for New Builds & Renovation

​

Arthur Acoustics provides specialist specification and certified UK installation of BASWA Casual, a sound-permeable acoustic spray plaster engineered both as a refined top coat on new BASWA ceiling installations and as a specialist renovation coating for existing acoustic plaster surfaces. Featuring a finely textured 0.3 mm to 0.5 mm mineral grain, BASWA Casual delivers a homogeneous, jointless finish with crisp architectural brightness while preserving full acoustic absorption.

 

Why Architects and Specifiers Choose BASWA Casual

​

Unlike conventional paint, which seals microporous surfaces and permanently destroys sound absorption, BASWA Casual is formulated with polymeric binders and open-pored mineral fillers so sound waves continue to pass effortlessly into the acoustic backing panel beneath.

  • Dual Purpose for New Installations & Refurbishment. Functions as an efficient spray-applied final coat over new BASWA Phon, BASWA Basic, or BASWA DTG systems, as well as a restorative refresh coat for soiled or aged acoustic ceilings.

  • Subtle, Homogeneous Textured Finish. Creates an even, slightly textured surface with a 0.3 mm to 0.5 mm grain size that masks minor surface variations across expansive ceiling planes.

  • Rapid Spray Application. Applied in two to three lightweight spray passes, allowing large areas to be finished or renovated quickly with minimal disruption and without requiring full-room birdcage scaffolding.

  • High Light Reflectance. Supplied in bright architectural white (~NCS S 0300-N), enhancing natural daylight distribution across commercial and residential spaces, with custom colour tints available on request.

  • Non-Combustible & Low-Emission. Carries a Euroclass A2-s1, d0 non-combustible fire rating, achieves a French VOC A+ rating, and supports BREEAM and LEED sustainability targets.

 

How the BASWA Casual System Works

​

For new-build projects, our accredited Arthur Acoustics craftsmen install high-density BASWA acoustic panels onto solid concrete, plasterboard, or direct-to-grid (MF) framing. Once the panel joints are grouted and sanded flat, BASWA Casual is spray-applied across two to three uniform passes to create a clean, continuous acoustic finish.

For renovation and maintenance, existing BASWA ceilings are first cleaned with BASWA Clean and any localized surface marks are repaired. Our team then spray-applies BASWA Casual directly over the existing microporous surface in one to two stages—restoring a fresh, bright, seamless appearance without stripping back the underlying acoustic panels or compromising acoustic performance.
