Acospray DC3


Acospray DC3

Acospray DC3 is our standard spray plaster and consists of two components. On the one hand a binding agent, on the other hand enriched cellulose fibres. The material can be applied in 10mm to a maximum of 50mm. In the latter case maximum absorption in the speech frequencies is achieved.


The material is applied by means of a spraying process in which various layers are sprayed crosswise. This creates a finish with a medium-fine spray structure.


The character of the Green Line fibers also allows it to be produced in Acospray DC3 version.


This product can be applied to almost any surface. Due to the hygroscopic properties, even in swimming pools to semi-outdoor situations such as balconies. Weight after drying per 10mm thickness of applied material 1.3 – 1.8 kg/m2.

-Option 1: Removing possible dust and cobwebs can be done with a vacuum cleaner with a soft cloth nozzle

-Option 2: Treat the surface with dry ice. A maintenance contract can also be concluded for this.



-Small repairs are easy to do manually

-Medium repairs can be picked up with our mini machine (38kg)

-Major repairs, refinishing with regular spray equipment (200kg)



-The material can be oversprayed using an airless spraying technique. We do not recommend using a rolling technique


Remove acoustic layer

-Moisten the material and let it soak for 24 hours. After that it is easy to remove


Basics application

-Substrate must be clean, dry and airtight (close plasterboard seams)

-Flatness of the surface determines the flatness of the end result

-Acoprimer promotes adhesion, prevents blood circulation and moisture saturation of the substrate

- Extend central boxes, etc. to the thickness of the spraying work

-If no termination by wall or frame, a closing profile must be placed from 10mm thickness

-Pre-treat metal parts against rusting

-Installation using mobile scaffolding and/or scissor lifts

-Temperature during and after application >15°C

-Installations/wall parts are sprayed as standard in 10mm thickness to allow the contours to be drawn
