The interior wall plaster types

Interior walls are mostly coated. For this purpose, a substrate is made of plaster. There are many different plasters. Below you will find the most important interior wall plaster types and their special features.

Today there are many special and technical plasters

Plasters are used around the house construction both inside and out alike. Due to (relatively) new construction techniques, a lot has changed in plastering as well. For example, there are special plasters for thermal insulation composite systems (ETICS) for insulating the façade. Damming is often done with EPS panels. Special plasters for these insulation systems slightly loosen the surface of the EPS panels so that the plaster forms a strong bond with them.

The changes in the interior design were not past cleaning

In the interior, the drywall is now a recognized building standard in interior design. Gypsum plaster is often used here. In addition, in damp rooms especially water-resistant plaster types (aquaprotect).

Overall, "the world of plaster" for the layman is not easy to understand, because in addition to numerous plaster types plasters are categorized according to different criteria, which confuse in addition. To get a general overview here, we recommend our detailed guide to cleaning types for interior and exterior plasters.

The most important interior wall plaster types

The following plaster types are particularly important for the interior wall:

  • gypsum plasters
  • lime plasters
  • cement plasters
  • Clay plasters
  • Gypsum-lime plasters
  • Lime cement plaster

As you can see, different types of plaster can also be combined again. Therefore, in a simple guide we can not go into every single detail. Rather, this guide is intended to Innenwandputzarten rather than orientation.

Interior wall plasters: gypsum plaster

Also due to the drywall interior design plaster gypsum are very widespread today. With gypsum plaster a surface up to grinding quality Q3 can be produced effortlessly. With fine gypsum plaster even from Q4. The advantage of gypsum plaster is at the same time its major disadvantage.

Plaster attracts water and stores it. Gypsum plaster regulates the room humidity and ensures a comfortable indoor climate. Too much moisture but gypsum plaster increases. Here they reach their limits, which is why the use is not possible outside. In damp rooms ordinary gypsum plaster can also not be used.

Cement and lime cement plasters

In wet rooms primarily lime cement plasters are used because of their positive properties with significant moisture exposure. But also cement plasters bring disadvantages. When using a wall heater, cement-based plasters are unsuitable for the interior wall, as it leads to many cracks in the plaster due to the heat development.

Clay plasters

Here, mainly clay plasters are used today. When clay plastering, it seems as if the Bauwelt just rediscovered these traditional plasters. Especially certain combinations such as wall heating and clay plasters seem to be made for each other, as our guide to wall heaters in half-timbered houses impressively shows. Even in drywall clay plaster in the form of drywall (clay building boards) finds its way. The serious disadvantage of clay plaster: they are water-soluble.

Lime plasters on interior walls

Lime plasters are also still used relatively frequently. Before the drywall had progressed so far, lime plasters were the dominant plasters on interior walls. Today, they are used rather as a flush or as a plaster base. Classic applications are on wet construction walls such as brick, concrete, aerated concrete, etc.

Tips & Tricks
