Gypsum Plaster
Machine ST-101
ST-101 Machine Plaster is a single-coat plaster material developed for interior wall and ceiling surfaces, based on high-purity natural gypsum stone and expanded perlite. Its formulation is specifically designed for machine-spraying applications, ensuring excellent pumpability, homogeneous mixing, and strong adhesion to the surface.
-
As a machine-applied plaster system for interior walls and ceilings on fair-faced concrete, brick, aerated concrete, and smooth plasterboard surfaces.
-
Used in various types of buildings such as residential complexes, residences, offices, hotels, and hospitals.
-
Ideal for construction sites where high-speed application is a priority.
-
Serves as the main plaster layer in interior spaces before paint or coating applications.
Application Area
-
Machine-application-ready formula — provides high fluidity and homogeneous distribution.
-
Expanded perlite ensures lightness and enhances thermal and acoustic insulation.
-
Enables smooth surface finishing — ideal before paint or decorative coatings.
-
High adhesion and crack resistance.
-
Wide range of application thickness; can be applied in two layers if necessary.
-
Environmentally friendly formulation, solvent-free.
