Composition of acoustic plasters:
The market-standard acoustic plasters impress with a great deal of diversity and flexibility. The acoustic plasters are usually made on the basis of perlite (ground and puffed volcanic rock) and consist of various components.
Predominantly dispersion-bound and mineral acoustic plasters are used.
Perlite itself already has a sound-absorbing effect, but its effect alone is not sufficient for optimum acoustics. The design and thus the formation of capillaries in the plaster causes it to remain sound-absorbing in the case of a direct coating and transparent in the case of a coating on acoustic panels.
The drying times between the individual applied layers are fundamental for functionality and appearance.
