How it works

Need to reduce reverberation?
Acoustic spray is your most effective solution.

Our acoustic spray is made from cellulose and gets seamlessly applied to ceilings and walls.

Thanks to its porous structure, it absorbs sound waves and significantly reduces room reverberation. This creates a more pleasant acoustic environment, minimizes noise pollution, and improves speech intelligibility.

We apply acoustic spray to absolutely any ceiling; it adapts to the desired shape and easily integrates lights, spotlights, fire alarms, pipes, cable ducts, ventilation systems, etc.

Our acoustic solution is highly effective, requiring only a few millimeters of room height and a tiny fraction of the overall construction budget.

Great acoustics.
Compelling arguments.

In contrast to acoustic panels or ceiling sails, our solution preserves architectural and design freedom while delivering superior sound absorption.

What's more: our acoustic plaster is highly sustainable. Like paper, it's made from cellulose and a natural, water-based adhesive.

A great solution.
Simple implementation.

We accompany your project from start to finish: During the planning stage, we help you choose the right type of material, texture, and color, make all the necessary preparations, and carefully apply the acoustic spray using spraying machines.

During the final inspection, surfaces and joints are checked. We are only satisfied when you are happy.

High quality.
Zero maintenance.

Once the acoustic spray has been applied and dried as a solution for soundproof ceilings and walls, the acoustic element requires very little maintenance or cleaning, even with intensive use.

But what if something happens? If needed, the spray plaster can easily be adjusted or supplemented later on.

Examples of Great Room Acoustics in Switzerland

Holcim Campus, office building for the building materials manufacturer in Zug

Acospray DC3, Concrete Grey (ILA), 25 mm

At Holcim's new headquarters in Zug, the acoustic measures seamlessly adapt to the building's free forms and materials. kustik applied Acospray DC3 in Concrete Grey (ILA), 25 mm directly onto the complex ceiling geometries. This creates a homogeneous, sound-absorbing surface made from recycled cellulose, which acoustically calms the space and seamlessly integrates into the diverse lighting, material, and atmospheric environments.

Office foryouandyourcustomers in Zurich

Acospray DC3, White, 25 mm

The offices of the consulting firm foryouandyourcustomers demonstrate how acoustic spray works. With Acospray DC3, white, 25 mm, reverberation dropped by 70%. Conversations are clear, meetings are more relaxed, and the work environment is calm and productive.

Studio Restaurant, Bar & Club in Zurich

Acospray DC3, Black, 30 mm

In the Zurich studio, Acospray DC3, in black and 30 mm, was applied. The reverberation was reduced by 90%. This acoustic spray creates a vast night sky, enhancing the sound and making the atmosphere the focal point.

Private House in the Zurich Oberland

Acospray DC3, White, 25 mm

Minimalism meets great room acoustics: Acospray DC3, white, 25 mm, was installed in a residential house in the Zurich Oberland. With 87% less reverberation, you get a calm, harmonious room feel – acoustically excellent, aesthetically understated.

Good questions:

  • The acoustic spray is highly versatile, seamlessly integrates into any design, and provides a continuous, smooth, and aesthetic surface with exceptional acoustic performance.

    Unlike acoustic panels or ceiling baffles, it preserves the architecture and design freedom while offering superior sound absorption. This is how we provide a design-oriented acoustic absorber solution.

    Another point: Our acoustic plaster is very sustainable. It's made from cellulose.

  • Acoustic spray plaster is versatile and suitable for spaces where a pleasant sound atmosphere is important. These include offices, restaurants, schools, hotels, supermarkets, healthcare centers, living spaces, museums, event halls, and so on.

    It's especially beneficial in large, open, or reverberant spaces since it integrates discreetly and noticeably improves the room acoustics. Even in smaller rooms, acoustic spray calms the atmosphere and creates a pleasant spatial feel. Check it out for yourself with a look at our references.

    Since acoustic spray is cost-effective and environmentally friendly, it is often used in warehouses, workshops and garages.

  • We can achieve surfaces in five different textures, from 'structureless, very smooth finish' with our Acoplaster F to 'coarse-grained spray texture' with our Acospray DC3.

    We offer twelve standard colors: White, Cool Grey, Concrete Grey, Anthracite, Black, Terracotta, Denim Blue, Olive Green, and the four special color blends from our Green Line product range. You're welcome to order samples of these colors and textures.

    We can create your custom color by adding water-soluble pigments to the adhesive. We achieve special effects by additionally spraying on acoustic paint. With careful application, the acoustic values are maintained.

    For international corporations and larger projects, we're happy to produce the cellulose fibers in a chosen, exclusive color.

  • Yes, acoustic spray plaster can be planned and applied even for existing or planned pendant lights, spotlights, ventilation pipes, cable ducts, motion sensors, WLAN devices, air conditioning systems, etc.

    • Option: Overspraying: Acoustic spray plaster can be applied to all ceiling and wall surfaces, even if technical installations are present. Thanks to its seamless application, it adapts to the existing conditions. We often apply the spray plaster directly onto installations like cable trays and ventilation ducts. This further enhances acoustic absorption, and the visual effect is often appreciated.

    • Option: Integration: Any object, be it lights, ventilation ducts, or air conditioning units, can remain accessible. In this case, we protect the objects, and the acoustic spray is carefully applied around them. With a few simple steps, we ensure a clean finish. For spotlights, motion detectors, etc., we create spacers using a 3D printer to embed them flush with the spray plaster surface.

    We're happy to find the optimal solution with you for how acoustic spray plaster can be used in your project.

  • We'll guide your project from planning to execution:

    • Planning: First, we clarify the acoustic requirements and design preferences. We'll help you choose the right material type, texture, and color. By briefly inspecting the spaces, we ensure all interfaces are clear and there are no surprises.

    • Preparation: The substrate must be load-bearing, clean, and dry. Depending on its condition, a primer or bonding agent is applied to ensure optimal adhesion. We carefully protect all walls and floors with a waterproof covering.

    • Implementation: The plaster is applied in multiple layers using a spray machine. The layer thickness varies depending on the desired sound absorption and surface appearance. This is followed by controlled drying.

    • Completion: We check all surfaces and joints. If you'd like, we can also carry out an acoustic measurement. After all, we're all about excellent room acoustics combined with appealing aesthetics.

    Our on-site work is usually pretty quick. Thanks to thorough preparation, our extensive experience, and our team and warehouse right here in Switzerland, we typically wrap up our projects within just a few days.

    And yes, even after the project is done, we're still right here for you if any adjustments or improvements are needed.

    Ultimately, what truly leads to an outstanding result is always a combination of great communication, solid preparation, quality workmanship, top-notch products, and local presence.

  • Acoustic spray plaster is low-maintenance, doesn't wear out, and barely needs any care or cleaning, even with heavy use.

    If needed, the spray plaster can be easily adjusted or enhanced at a later stage.

  • We promise: Our spray plaster provides the best acoustic improvement for every franc spent.
