a result of the modern energy saving construction and rehabilitation, in
addition to the classic rendering bases made from masonry and concrete, also
insulation panels are increasingly appearing as background for rendering work. MultiGips
plasters are, inter alia, ideally suited for this application due to their low
The insulation panels, in accordance with the specifications of the
manufacturer, must be close to each other, free to move and mounted securely.
- Wood-wool building slabs are fundamentally to be provided with a fully covering rough plaster on a mineral basis with high grain size [0 – 5 mm] before the initial rendering The surface of the rough plaster is not processed, however, one has to await the complete drying out. Subsequently, apply MultiGips plasters with a reinforcing fabric in the upper third of the plaster layer. Minimum plaster thickness 15 mm.
- Rigid, expanded polyurethane slabs made from expanded or extruded polystyrene [EPS or XPS, e.g. inter alia, styrofoam, styrodur] as well as from polyurethane [PU] must be volume-stable and suitable for rendering in accordance with the declaration from their respective manufacturer. The employment of grooved slabs is preferred. Otherwise the surface must be roughened using the teeth of a saw or alternatively MultiGips Betonkontakt is to be applied. Press on thinly rendered reinforcing fabric and replaster fresh-in-fresh up to the minimum plaster thickness of 15 mm. Separate the edges of the plastered surface from the flanking building units using a trowel cut.
- Foam glass forms a very plastering-friendly background. The slabs must be glued together in accordance with manufacturer’s details using system-own glues. a further treatment before rendering is, as a rule, not necessary, however, a fabric insert in the upper third of the plaster layer can be recommended.
