Acoplaster is the most finely finished acoustic plaster available. The structure consists of two components: the mineral wool panel and the finishing layer. The material is applied in a total package thickness of 35mm (3mm plate adhesive, 30mm mineral wool, 2mm plaster layer).
The material is applied by means of an assembly process, in which the sheet material is glued to the full surface of a plasterboard or directly to the structural substrate. A layer of plaster is then added. When the plaster layer has dried, the whole surface is sanded to correct any imperfections. Afterwards, any damage is easy to repair invisibly by spreading on an extra bit of material and sanding it after drying.
This product can be applied to almost any surface. It can even be used in swimming pools, due to its hygroscopic properties. The weight after application is 7-8 kg/m2.
