Primers for marble plaster, lime paint and mineral surfaces

The right primer for every substrate

Careful substrate preparation is crucial for the application and subsequent appearance of mineral surfaces. Our primers regulate absorbency, improve adhesion and create the ideal base for marble plasters, lime paints and other mineral coatings.

Depending on the substrate and the subsequent material, different primers are used – ranging from bonding primers containing marble powder or vegetable casein, through to casein deep-penetrating primers and mineral lime bonding plaster.

Primers for secure adhesion and even application

With high-quality marble plasters, a good result starts with the substrate. Particularly with Stucco Veneziano and Marmorino, the surface should be prepared to ensure even absorption and sufficient texture. The right primer makes application easier and creates the basis for a uniform surface finish.

Our bonding primers are deliberately different from many commercially available quartz sand-filled bonding primers. Instead of hard quartz sand, these products use soft marble powder. This reduces the risk of metal abrasion when working with a trowel – an important advantage, particularly on smooth and polished marble render surfaces.

Adhesive primer with marble powder or vegetable casein?

Both variants create a suitable substrate for further coating, but differ in the binder used.

The adhesive primer with marble powder contains an acrylate-styrene dispersion as a binder and provides a textured surface for subsequent application.

The eco-friendly adhesive primer with vegetable casein is the alternative for applications where particular emphasis is placed on selecting environmentally friendly materials, even during substrate preparation.

Depending on the product, the adhesion primers are suitable for use on, amongst other things, concrete, tiles, glass, plasterboard, MDF, OSB, existing wall paints and other load-bearing substrates.

Casein deep primer for absorbent substrates

The casein deep primer is primarily designed to even out highly absorbent or unevenly absorbent substrates and to stabilise chalking or sanding surfaces.

In particular, before applying lime paint, a uniformly prepared substrate ensures a smoother and more even finish. The primer dries to a transparent finish, thus forming a suitable base for the subsequent mineral coating.

Adhesive render for challenging substrates

The lime bonding plaster is a mineral lime mortar with adhesion-enhancing additives and is suitable for preparing challenging substrates for subsequent coating with our marble plasters.

Furthermore, it can be used for more than just a base coat. Depending on the desired finish, it can also be applied as a white top coat and, for example, smoothed, textured or felted.

Which primer is the right one?

The choice of a suitable primer depends on the existing substrate and the planned topcoat. You will find detailed information on suitable substrates, application and coverage on the relevant product pages.

For applying Stucco Veneziano and Marmorino, you will also find the appropriate bonding primers there, as well as solutions for preparing substrates for lime paint or other mineral-based coatings.

In the case of unusual or problematic substrates, we recommend checking suitability before starting work. We’d be happy to assist you in selecting the right product.
