Acospray DC1

The DC1 impresses with its extremely fine texture. After a spray of up to 20 mm, it is smoothed again. For better sound absorption, an Acoboard can optionally be used as a substrate.

Acospray DC1 is available in white and in your desired color.

Specifications

  • Acospray DC1 is a sustainable and sound-absorbing spray plaster with a smooth finish. The outstanding acoustic properties are achieved by a mixture of cellulose fibers in combination with polymers and water-based binders. The material can be applied in a thickness of 5 to 20 mm.

  • In order to achieve very high absorption values, it is possible to apply the spray plaster to a mineral wool panel with a total thickness of 40 mm (3 mm adhesive, 30 mm panel, 7 mm Acospray DC1).

  • The material is applied using a special spraying process in which several layers are sprayed on crosswise. To obtain a smooth surface, it is then smoothed. This creates a diffusion-open surface with a very fine texture.

  • Acospray DC1 can be used on almost any surface. Thanks to its hygroscopic properties, it can be used in swimming pools or extensions to living spaces, such as balconies. The weight after drying is a light 2 - 3 kg/m² per 10 mm application thickness.

    • Cradle2Cradle Institute, certification level achieved: Cradle2Cradle Bronze

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

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

    • Frauenhofer, DIN EN 16516, VOC, meets requirements for building products with regard to VOC and SVOC 2015/NIK list 2015: fulfilled

    • Intertek, ASTM standard D7234, adhesive strength ≥ 736 to ≤ 12600 dead 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 directive in Switzerland

  • White and any other specified colors by adding pigments to the binder.

  • Dust and cobwebs can be removed using a vacuum cleaner with a soft textile nozzle attachment. Another option is cleaning with dry ice. We are happy to offer a maintenance contract for both options on request.

  • Small repairs are carried out manually, medium-sized repairs with our mini machine (38 kg) and large repairs are carried out with the standard sprayer (200 kg).

  • The material can be sprayed over using an airless spraying technique. The application of paint with a paint roller is not recommended.

  • After moistening and 24 hours exposure time, the material can be easily removed without leaving any residue.

    • The substrate must be clean, dry and airtight (drywall joints must be sealed)

    • The surface quality of the substrate determines the evenness of the final result

    • Acoprimer promotes adhesion, prevents leakage and moisture saturation of the substrate

    • Junction boxes and the like must be extended by the thickness of the insulation layer

    • If a flush finish cannot be achieved through the wall or window/door frame, an end profile of 10 mm thickness or more must be fitted

    • Metal parts must be pretreated against corrosion

    • Assembly using mobile scaffolding or lifting platforms

    • Temperature during processing ≥15°C

    • Installations/wall sections are sprayed with a standard thickness of 10 mm

    • To speed up the drying process, we recommend the use of fans and construction dryers; a moisture meter is provided to monitor the process

    • Cuffs or 3D-printed constructions are available for spots
