Not smooth enough? Try Sonaspray® FCX-TR!

TR White

To further soften the aesthetics of the structure, the plaster can be smoothed by hand. We then get a surface that is a little more even, but still porous. This version has the designation TR (troweled).

Too few colors? Choose any RAL color you want!

The Sonaspray® plaster system is available in a range of colors - from classic whites and grays to beiges and deep black. We also have an environmentally friendly, non-tinted Sonaspray® ECO plaster available. However, sometimes a very specific shade is needed for a project, harmonizing with the rest of the interior elements.

At Baukustik, we understand the needs of architects very well and have a solution for this. We are able to make Sonaspray® plaster for you in any RAL color. Contact our expert for details.

Sonaspray® products and the environment →

Sonaspray® is an environmentally friendly plaster. Production is carried out in a sustainable and safe manner. It uses recycled materials (mainly cellulose) and the installation process generates very little waste.

The reference life of the material is about 75 years. The products also have a number of certifications, guaranteeing that they are low-emitting, and the composition is free of heavy metals and Red List chemicals.

How do we make Sonaspray® plasters?

Thanks to our team of installers, the execution of Sonaspray® plaster is very efficient. For simple rooms, we are able to achieve a capacity of up to 300 m² per day.

How does the installation go? After preparing the machine and material, we will need to protect the walls and floors in your space, as this is a dusty job. We then spray the plaster, and clean the room afterwards. With this system of work, we are able to offer installation and acoustical improvement in already functioning buildings.
