Acospray DC3
This composite, featuring a coarse spray texture of binder and cellulose fibers, allows for flexible application from 10 to 45 mm. With numerous variants and fantastic absorption in the speech frequency range, the DC3 is definitely our go-to spray plaster.
Acospray DC3 is also available in your desired color.
Specifications
Acospray DC3 is our go-to sustainable, sound-absorbing spray plaster. It's a two-component system, combining a binder with enriched, recycled cellulose fibers. To really get the most out of its outstanding acoustic performance, we suggest applying the material in a layer thickness ranging from 10 mm up to a maximum of 45 mm.
We apply the material using a specialized spray technique, where multiple layers are cross-sprayed. This results in a surface with a coarse-grained, diffusion-open spray texture.
Acospray DC3 can be applied to almost any surface. Once dry, it weighs just 1.3–1.8 kg/m² per 10 mm of application thickness.
You can also get Acospray DC3 in our Green Line variants: Billboard Grey and Apple Grey.

You can remove dust and cobwebs using a vacuum cleaner with a soft textile nozzle attachment. Another option is dry ice cleaning. If you'd like, we're happy to offer a maintenance contract for both methods.
-
Small repairs are done manually, medium-sized repairs with our mini-machine (38 kg), and large repairs are carried out using the standard spray equipment (200 kg).
-
The material can be over-sprayed using an airless spray technique. Applying paint with a roller is not recommended.
-
After moistening and allowing it to soak for 24 hours, the material can be easily and completely removed without residue.
-
The substrate must be clean, dry, and airtight (drywall joints need to be sealed).
The surface quality of the substrate determines the flatness of the final result.
Acoprimer enhances adhesion, prevents bleeding, and stops the substrate from becoming saturated with moisture.
Junction boxes and similar components must be extended by the thickness of the insulation layer.
If you can't achieve a flush finish with a wall or window/door frame, you'll need to install an edge profile of at least 10 mm thickness.
Metal parts should be pre-treated against corrosion.Installation using mobile scaffolding or lifting platforms.
Processing temperature ≥15°C
Installations/wall sections are sprayed with a standard thickness of 10 mm.
To speed up the drying process, we recommend using fans and construction dehumidifiers; a moisture meter is provided for monitoring.
For spotlights, there are sleeves or 3D-printed constructions.

This product is a sample from the product line Acospray DC3.
Acospray DC3 is our sustainable standard acoustic spray plaster made from recycled cellulose and a water-based binder. The material is sprayed on in several fine layers, forming a coarse-grained, diffusion-open surface with excellent sound absorption. It's applied in layer thicknesses from 10 to 45 mm and is suitable for almost all substrates – even in damp rooms like swimming pools. Weighing only 1.3–1.8 kg/m² per 10 mm, it remains lightweight, robust, and versatile.
You can order up to three samples (shipping included) for free. For orders of more than three samples, a shipping and handling fee of CHF 25 will apply.
