It can happen that adhesive and reinforcement mortar must be felted. You can read in this guide whether you can felt adhesive and reinforcement mortar, and what also needs to be considered.
Manufacturer's information on felting adhesive and reinforcement mortar
Felting a plaster describes the smoothing of the surface when it, in this case reinforcement mortar, is dry. You can find out whether the adhesive and reinforcement mortar you are using can be felted from the information provided by the mortar manufacturer in question (€ 7.79 at Amazon *).

Types of reinforcements
But in addition, you also need to know what type of reinforcement mortar you are using:
- Adhesive and reinforcement mortar (especially for ETICS)
- Reinforcement mortar modified with reinforcement fibers
- conventional mortar with reinforcement mesh or mesh
Felting adhesive and reinforcement mortars: two techniques
According to the manufacturer, most adhesive and reinforcement mortars can be felted. In principle, you proceed in the same way as when felting a conventional finishing plaster. There are two possible approaches. For both, you will need a felt board and clean water.
First possibility for felting adhesive and reinforcement mortar
You apply a little water to the mortar surface and then start to felt the surface with the float in circular movements. You carry out this until the surface of the quality you expect in terms of smoothness or. Corresponds to flatness. Then you have to let the surface dry for a correspondingly long time. Remember that adhesive and reinforcement mortar can absorb a lot of water.
Second procedure for felting adhesive and reinforcement plaster
The second option is to pre-wet the felt board, not the wall. Then do the same thing. The mortar or plaster surface is smoothed or smoothed in circular movements. felted. Between felting, you have to keep dipping the felt board into the water. After a short time you will have a feeling for the optimal level of moisture. Here, too, you have to wait until the moisture has completely dried off before further processing of the plaster.Tips & Tricks If you want to felt the adhesive and reinforcement mortar because you want to use reinforcement mortar as a finishing plaster: in principle, adhesive and reinforcement mortar is not suitable for this (ETICS reinforcement mortars with special properties are used as adhesive and reinforcement mortars). Tips & Tricks These have a high tensile strength and a low compressive strength. Conventional finishing renders have a low tensile strength and a high compressive strength. That means they are harder and more mechanically resilient. Reinforcement plasters also absorb a lot of water.
