Acospray DC2

For those who prefer a fine spray texture and don't want to compromise on speech frequency absorption. This spray plaster combo of binder and cellulose fibers creates a calm atmosphere.

Acospray DC2 is also available as Green Line and in your desired color.

Specifications

  • Acospray DC2 is a sustainable, sound-absorbing spray plaster. It's made of two components: a binder and enriched, recycled cellulose fibers. You can apply the material in thicknesses from 5 to 45 mm. Even at a layer thickness of 25mm, it achieves excellent absorption in speech frequencies.

  • The material is applied using a special spray process, where multiple layers are sprayed on crosswise. This creates a diffusion-open surface with a fine spray texture.

  • Acospray DC2 can be applied to almost any substrate. Thanks to its hygroscopic properties, it's suitable for use in swimming pools or semi-outdoor areas like balconies. After drying, its weight is a light 1.5 - 2.0 kg/m² per 10 mm of application thickness.

  • This product is also available as Green Line with India Yellow or Hong Kong Grey fibers.

    • Cradle2Cradle Institute, achieved certification level: Cradle2Cradle Bronze

    • MRPI (Dutch, environmentally relevant product information), ISO 14025 Environmental Product Declaration: compliant

    • MRPI, LCA according to the determination method of the Dutch Stichting Bouwkwaliteit (Construction Quality Foundation), MKI (Environmental Costs) A-D 0.24ct/m² for the mass-supported variant

    • Frauenhofer, DIN EN 16516, VOC, meets requirements for construction products regarding VOC and SVOC 2015/NIK list 2015: fulfilled

    • Intertek, ASTM Standard D7234, adhesion strength ≥ 736 to ≤ 12600 self-weight

    • Intertek, ASTM Standard C1338-19, microbiological resistance, compliant

    • Intertek, Standard ISO105-A02, color change, Class 5

    • Efectis, 1350-1:2018, B-s1.d0, additionally the new borate-free variant B-s2.d0, corresponds to fire behavior group RF2 of the VKF fire protection guideline in Switzerland

    • White

    • Cool Grey

    • ILA (Concrete) Grey

    • Black

    • Many other specific colors are available. The coloring is achieved by adding pigments to the binder.

  • 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 a flush finish isn't achieved by a wall or window/door frame, an edge profile of at least 10 mm thickness must be installed.

    • Metal parts need to 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.
