The system consists of a cork-based plaster, eco-friendly, sound-absorbing, and breathable, with excellent sound absorption capabilities called Diathonite Acoustix⁺. It is a mortar formulated with cork, clay, natural hydraulic lime NHL 5, diatomaceous powders, and hydraulic lime. The plaster eliminates reverberation and reduces reflected noise. The product has high breathability, good thermal insulation characteristics, dehumidifying capabilities, and excellent fire resistance. If a smooth appearance is desired for interior walls, the application of the Aquabond primer, a ready-to-use adhesion primer, is recommended. When the thickness exceeds 6 cm, the eco-friendly mortar must be reinforced with a fiberglass mesh called Polites 140, and regardless of the thickness, it must be used for applications on panels, wood, plasterboard, or on surfaces subject to movements.

The sound-absorbing plaster is then smoothed out with Argatherm Acoustix, an acoustic finishing skim coat lightened with expanded spherical mineral fillers with a microporous internal structure that gives the product extraordinary lightness, thermal insulation, and sound-absorbing properties, providing a smooth surface. The system is then finished off with Limepaint paint for indoor applications, after priming with D20, a water-based acrylic resin bonding agent.
