Types of rubbing plaster: Plaster for inside and outside

Rough plaster has probably already been encountered visually by everyone, whether on the inside or outside of a building. However, what many do not know is that this plaster for indoor and outdoor has major differences: Different types of rubbing plaster differ in their composition and thus also in their use. Textured plaster for the inside cannot therefore automatically be used outside and vice versa. In this article, we explain the different types of rubbing plaster.

Exterior plaster

The types of textured plaster for the outside include synthetic resin plaster, mineral plaster and a mixture of these two, as well as plaster systems in special cases. But what is behind these terms?

synthetic resin plaster

Synthetic resin plaster is one of the most frequently used types of textured plaster. As a finishing plaster, it is easy to work with and, with its adaptability to the substrate, is a safe choice even for beginners. Manufacturers use a polymer dispersion as a binder so that the synthetic resin is finely distributed in the plaster. The synthetic resin plaster is particularly resistant and therefore ideal for outdoor use. In addition, it is elastic and adapts to the deformations of the subsoil. This has the advantage that it can be applied thinly and hardens faster. However, it is important to know that synthetic resin plaster has water-repellent properties. Because of this, moisture accumulates on the facade, which dries poorly under certain conditions. This can lead to algae or fungal infestation.

mineral plasters

Mineral plasters are made with inorganic binders of mineral origin. With the material made of rock, you can put “stone on the wall”, so to speak. Lime and cement are usually used as binders. Mineral plasters have the great advantage that they naturally absorb moisture and release it again. There is therefore no damage due to moisture. Mold and algae don't stand a chance here because the moisture they need to survive is not available. In addition, you will not find any food in the inorganic material. Mineral plasters also offer a hard and resilient surface, which is also prone to cracks.

mixed plaster

A mixed plaster is, for example, silicate plaster, which consists of potash water glass with a synthetic resin dispersion. Depending on the composition, it has different properties. It can be dense like synthetic resin plaster or permeable to water vapour. With mixed plaster you can create all gradations between the two starting points of the types of textured plaster just described.


In addition to the first three types of rubbing plaster, there are also plaster systems that consist of several layers, for example a base and top coat. Plaster systems are used, for example, in thermal insulation composite systems (ETICS). Different types of textured plaster can form the two plaster layers.

Interior plaster

When it comes to the types of textured plaster used indoors, a distinction is again made between synthetic resin plaster and mineral plaster. In contrast to the outside area, there is more to be said for mineral plaster here. Because it scores above all with its property of absorbing moisture and releasing it again. The living climate is much more pleasant thanks to this regulation of the humidity.

There is an exciting selection of base materials for interior mineral plaster: gypsum, lime, clay and ready-to-use mineral plaster. Each of them has its own advantages and material mixtures offer even more possibilities. What is best for the base material depends entirely on your needs and your home. We would be happy to advise you with our many years of experience.


Which plaster can be processed into which type of textured plaster depends, among other things, on the consistency of the individual plaster mixtures. Each of the types of rubbing plaster has its own individual advantages in use. As a specialist, MVM can give you the best advice here.
