Acospray DC1

Acospray DC1 is a machined finish that consists of two components. On the one hand a binding agent, on the other hand enriched cellulose fibres. The material can be applied in 5mm to a maximum of 20mm in the mass (figure 1).

 

It is also possible to apply this to a mineral wool (figure 2) if very high absorption values are to be achieved. Package thickness 40mm (consisting of 3mm plate glue, 30mm absorbent plate material, 7mm Acospray DC1).

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

 

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 2 – 3 kg/m2.

Cleaning

-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.

 

Repairs

-Repairs are easy and can be picked up with our mini machine (38kg)

 

To paint

-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)

-We recommend applying a green plasterboard as a substrate

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

-Acoprimer promotes adhesion and ensures a proportional suction power 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

-Pre-treat metal parts against rusting

-Installation using mobile scaffolding and/or scissor lifts

-Temperature during and after application >15°C
