Gypsum Plaster
With Perlite ST-100
Perlite Plaster ST100 is a high-quality, ready-mix gypsum plaster based on refined gypsum stone and expanded perlite, designed for single-coat application. Thanks to its perlite filler, it provides superior thermal and acoustic insulation. With its strong coverage, easy application, and excellent surface smoothness, it offers a modern alternative to traditional plastering for interior walls and ceilings.
