Durable, ecologically-sound and aesthetical

Mineral renders and fillers from KEIM are durable, ecologically-sound and aesthetical. Give rooms and buildings a new face with different surface structures and extravagant special effects.

Boundless creativity and design possibilities

Whether smoothed, structured, filled, floated, processed with a roller and stencil, or washed-out using the brush. Coloured with pigments or with various types of grains. Renders make many different design options possible.

After years of smooth renders being the status quo among builders and architects, we are currently experiencing the renaissance of coarsely structured render surfaces that are processed using trowel, float, putty knife, brush or broom.

To ensure that the desired result is achieved, in-depth knowledge and skilled craftsmanship are required in order to carry out the processing techniques.

Discover the design variety of mineral renders:

floated work and plasterwork

The plaster is rubbed when fresh with a sponge float to the grain strength wanted, and this is how the typical structure comes about. KEIM mineral renders offer the optimum processing properties.


In the fresh, still moist render, the trowel with the long edge is set-on, a little pressure applied and a small section of the surface render is removed. Depending the plasterer's individual "signature", an individual surface look emerges.


The still moist render is given a structured look using either a brush or broom. Vertical or horizontal structures can be created in the process.


When this technique is employed, the render is moulded when still wet. Special trowels are often used in this case. Wooden slats can also be used for moulding work. Applying this technique on a large surface requires a lot of skilled craftsmanship.

Stroked render

Significantly clearer marks than brooms and brushstrokes are created by the bar, which leaves clear, strong grooves in the plaster. Heavily horizontally or vertically structured surfaces are the result.


One or more superimposed layers of plaster are scratched out to template, creating exposed, raised structures, patterns or ornaments.

Scratched plaster is made from the top coat. As a result, the grain pops out and the unmistakable structure of the scratching plaster is created.                                                                                                                                              

Pin board plaster

The 'pin board' is similar to a fakir board, in which still soft plaster is pressed and leaves in this way a small-scale, less strong structure than is the case with painted techniques.
