Differences in reinforcing plaster

You can distinguish reinforcing plaster after use as well as after the structure of the plaster system. First, the technical distinction, which already specifies the possible applications:

Adhesive and reinforcing plaster for facades with ETICS

  • Reinforcement plaster for conventional facades and inside (with reinforcing mesh or fibers)
  • conventional mortars and plasters with reinforcing mesh or reinforcing mesh
  • Adhesive and reinforcing plaster for ETICS Apply

In a thermal insulation composite system, the reinforcement plaster is basically used as a plaster base. At the same time it absorbs movements of the rigid foam boards and distributes them stress-free. It is a special adhesive and reinforcing mortar used, which is often chemically treated so that when it is applied to the foam boards such as EPS insulation boards slightly dissolves the surface and thus firmly bonds.

This reinforcement plaster is usually applied in a thickness between 2 and 3 mm in a thin bed. Incidentally, this adhesive and reinforcing mortar is not suitable as a finishing coat.

Reinforcement plaster for facades and inside

A reinforcing plaster on conventional facades is applied, if it can be assumed that cracks could occur in the plaster. This is partly true for thermal cracks or for a crack-prone old plaster anyway.

Such a reinforcing render can not prevent cracks in the plaster, which are the result of thermal or shrinkage cracks in load-bearing structural parts. In this case, appropriate building plans must also be taken over in the plaster. Arm Reinforcement plaster is also used on the inside of walls. The reinforcement is inserted into the upper third of the entire layer thickness of the reinforcement plaster. Overall, the layer thickness here but also not more than 15 mm.

Then the top coat is applied. Also, this Armierungsputz is, if it is explicitly to Armierungsputz, only conditionally as a top coat, as it has other properties that are contrary to those of conventional plasters.

Tips & TricksIn addition, it is also possible to use reinforcing mortar in the floor. Here, however, a reinforcing fabric is often used for the conventional leveling compound for the screed floor.Tips & TricksWhen using reinforcing fabrics is also to be considered that conventional plasters are less well suited here. Special reinforcing mortars are applied with a high degree of compaction, many conventional plasters do not achieve this density.
