BASWA Maintenance | Care, Cleaning & Restoration of Acoustic Plaster
Arthur Acoustics provides specialist aftercare guidance, preventative maintenance, and nationwide UK restoration services for BASWA seamless acoustic plaster systems. Engineered from natural marble-sand and microporous mineral substrates, BASWA ceilings and walls are inherently low-maintenance and anti-static. Following simple care procedures—and never applying conventional paint—keeps your acoustic surfaces looking crisp, clean, and performing at full Class A sound absorption for decades.
Routine Cleaning & Everyday Care
Because BASWA systems are sealed at the rear against air movement, airborne dust is not drawn through the plaster pores. Routine upkeep requires only gentle dry cleaning methods:
-
Soft Vacuuming. Use a standard vacuum cleaner fitted with a clean, soft-bristled brush attachment to remove light surface dust and cobwebs without applying pressure.
-
Compressed Air Dusting. For high-level or delicate 0.3 mm Top finishes, dry, oil-free compressed air can be used from a safe distance to lift loose dust particles cleanly.
-
Dry Microfibre or Feather Dusters. Lightly sweep the ceiling plane with a clean, dry electrostatic duster during scheduled building maintenance.
-
Avoid Wet Wiping or Abrasive Scrubbing. Never use damp cloths, household detergents, or abrasive sponges on microporous plaster, as moisture can push surface dust deeper into the mineral pores and cause localized staining.
Treating Localised Marks, Scuffs & Impact Damage
Accidents during building maintenance, lighting changes, or day-to-day occupation can occasionally leave localized marks or minor dents. Arthur Acoustics offers tailored repair solutions to restore seamless continuity:
-
BASWA Clean Stain Treatment. Minor organic marks, fingerprints, or localized discolouration can often be lifted safely using specialist BASWA Clean enzymatic cleaning sprays without clogging the micropores.
-
Seamless Spot Repairs. Small knocks, screw holes from relocated fixtures, or localized impact damage can be filled and hand-trowelled with matching BASWA Base, Fine, or Top repair compounds by our certified technicians.
-
Colour-Matched Touch-Up Kits. For tinted ceilings, Arthur Acoustics retains your project's exact batch formulation so localized repairs blend invisibly into the surrounding surface.
Full-Ceiling Refurbishment with BASWA Casual
Over many years of service—or following building renovations, smoke exposure, or environmental wear—an entire acoustic ceiling can be refreshed without stripping back the underlying panels:
-
Never Paint Over Acoustic Plaster. Conventional emulsion, matt, or masonry paints form a sealed polymer film across the marble grains, blocking sound waves and permanently destroying acoustic absorption.
-
Acoustically Transparent Spray Renovation. Using BASWA Casual, our accredited teams spray-apply a fresh, microporous mineral coating directly over the prepared ceiling in one to two passes.
-
Factory-Fresh Brightness & Full Acoustics. BASWA Casual restores crisp architectural whiteness (~NCS S 0300-N) or custom colour tones while keeping the open-pore structure completely permeable to sound.

BASWA Clean
BASWA Clean F01 is a 2-component cleaning agent, which contains enzymes. It’s used for clean- ing surfaces and / or the partial cleaning of organically contaminated and discoloured BASWA Phon a acoustic plaster surface. It is part of the BASWA Maintenance Concept for maintaining and renovating BASWA surfaces and can therefore be combined with other techniques used (dry cleaning of heavily or partially contaminated surfaces, restoration of surfaces that have discoloured over time with BASWA Fresh). Cleaning the surfaces with BASWA Clean F01 is not a substitute for the complete renovation, but it can significantly extend the service life of a BASWA Phon acoustic plaster surface. When applied correctly, the product lightens the soiled colour tone and gives the surface a fresh look, without impairing its acoustic properties (after multiple applications this can create a slight glimmering effect on the surface). BASWA Clean F01 can be used on white BASWA Phon surfaces. If the surface is coloured there is the risk of discolouration and cloud formation!
BASWA Protect
BASWA Protect is a specially developed premium impregnation system for achieving an in-depth water repellent with optimum protection for BASWA acoustic plaster surface. The acoustic performance of the treated surface is not affected by this.
The deep penetration of BASWA Protect into the acoustics plaster system will significantly lower dirt and water absorption. This prevents the immediate ingress of liquids and thus reduces its capacity for absorbing contamination in liquid form and dirt particles that are mixed in with liquids.
Furthermore, the impregnation can have a positive influence on the cleaning of BASWA surfaces, as well as on their durability.
BASWA Fresh
BASWA Fresh is a mineral dispersion product for the paint-based renovation of BASWA surfaces discolored as a result of aging and use. It is a solution that is part of the BASWA Maintenance Concept that keeps BASWA surfaces looking goods and refurbishes them. Hence, it is compatible with other BASWA Maintenance Concept products, e.g. BASWA Clean or BASWA Blonde. However, please keep in mind that treating surfaces with BASWA Fresh is not a substitute for a complete refurbishment. Nonetheless, it has the capability to extend the useful life of a BASWA surface signi- ficantly. Its professional application refreshes surfaces discolored as a result of aging or bleaching and makes BASWA surfaces look virtually new. If at all, this treatment affects the acoustic perfor- mance of the surface only very minimally. However, BASWA Fresh is not the product you should choose if you are planning to change the colour of your existing BASWA acoustic plaster surface
Important! It cannot be ruled out that if you treated dyed BASWA acoustic surfaces with BASWA Fresh the paint colour may differ minimally from the original colour.
