Smooth plaster and rubbing plaster: properties and differences


Smooth plaster and rubbing plaster show some differences. The usually only thinly applied smooth plaster is somewhat harder to produce, since you can see even the smallest bumps after applying to the wall. The rubbing plaster can be individually designed and provided with its own patterns. So there are many differences between the two plaster types.

The main differences between smooth plaster and rubbing plaster

The classic rubbing plaster is applied with a regular trowel and smoothed and structured with a float. One differentiates between different grain sizes of additives. We are often talking about the Munich Rauputz or the so-called Wurmputz. The mineral rubbing has the advantage that it is breathable, is considered very resistant and therefore can be applied to exterior walls easily. The rubbing compound usually consists of mineral components. The smooth plaster is a slow-setting material made of lime or clay plaster. This is applied with a smoothing trowel or a flat iron. It is mainly used indoors and processed to create a smooth wall surface.

Advantages of both plaster types

A few advantages of the rubbing plaster have already been mentioned. However, the rubbing compound offers a few more advantages:

  • He is very resistant and can therefore also be used outside.
  • In addition, smaller cracks can be easily bridged with it.
  • Minor damage in the masonry or underground will be virtually invisible when a slightly coarser material is applied.
  • An important advantage of the rubbing compound is also its relatively simple processing.

But also the smooth plaster has its advantages. It can be very smooth and even surfaces produce. In addition, the material can be much better repaired or repaired in case of damage. However, it should not be concealed that with smooth plaster a more careful way of working is necessary. In addition, the surface must be level, since unevenness here much more effective than the rubbing.

The preparation of the wall is important in both Verputzarten

The walls should always be freed of loose components before application and thoroughly cleaned. If necessary, it makes sense to apply a primer. Especially if later plain plaster is to be processed, you should pay attention to a proper surface condition of the walls and a suitable primer.
