Interior plaster, surfaces

In addition to the colouring, the appearance of the interior plaster is significantly influenced by the surface structure, which results from the material composition, the type of application and, if necessary, the post-processing of the top plaster. Not every structure can be produced with every interior plaster, for most products the manufacturer specifies for which surfaces the respective top plaster is suitable.

 

Coloured stone plaster: A coloured stone plaster is a synthetic resin plaster with natural-coloured or coloured stones, but without opaque pigments. After drying, only the stones contained are visible, which form an opaque decorative layer. The design can be influenced by the use of homogeneous or different colours and grain sizes.

 

Felt plaster: After a short period of time, the plaster is felted and textured with a felt or sponge board.

 

Smoothing plaster: After a short standing time, the plaster is treated with a trowel.

 

Trowel plaster: the plaster is thrown on the wall and then removed with a trowel. The type of peeling determines the structure and regularity/irregularity of the surface.

 

Modelling plaster: Modelling is carried out e.g. with a roller, dripper, sponge, trowel or brush, so the range of design options is correspondingly wide. The trowel stroke plaster and the Old German plaster are also modelling plasters.

 

Rubbing plaster: Large grain additives (up to 5 mm grain diameter) in conjunction with surface smoothing by a rubbing board made of wood or plastic, depending on the direction of the rubbing movements, lead to a characteristic smooth surface with elongated depressions, which, depending on their appearance, are also referred to as grooved plaster, Munich rough plaster, worm plaster or maggot plaster.

 

Roller plaster: A roller plaster is modelled with a special roller, e.g. a pea hole roller, and thus acquires a characteristic structure.

 

Window plaster: Window plaster is applied with a metallic trowel and then smoothed. During drying, the fine components of the coating material sink between the coarse grains, creating a plastic grain structure.

 

Painted plaster: similar to roller plaster, but applied with a brush.

 

Spray plaster (formerly also referred to as broom plaster in a similar version): A fine-grained (grain max. 3 mm) low-viscosity mortar is applied with the spray plastering machine. This creates a more or less rough surface.
