Acospray DC3

The composite in a coarse spray structure made of binder and cellulose fibers enables flexible application from 10 to 45 mm. Many variants and great absorption in the speech frequency range make the DC3 our spray plaster favorite.

Specifications

Acospray DC3 is our sustainable, sound-absorbing standard spray plaster. It consists of two components: Binder on the one hand, and enriched and recycled cellulose fibers on the other. To achieve the outstanding acoustic properties of the product, we recommend applying the material in a layer thickness of 10 mm to a maximum of 45 mm.
The material is applied using a special spraying process in which several layers are sprayed on crosswise. The result is a surface with a coarse-grained, diffusion-open spray structure.
Acospray DC3 can be applied to almost any substrate and, thanks to its hygroscopic properties, it can even be used in swimming pools or extensions to living spaces, such as balconies. After drying, the weight per 10 mm application thickness is a light 1.3 - 1.8 kg/m².
The Acospray DC3 version is also available in the Green Line variants Billboard Grey and Apple Grey.

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 with a thickness of 10 mm or more must be fitted
  Metal parts must be pre-treated 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
