NATURAL PAINTS, BRUSHED PLASTER, LIME AND SILICATE PAINTS

Choosing a paint is far more than a purely aesthetic decision. For the building-physics benefits of your clay plaster to be retained over the long term, the paint layer must act like a “second skin”. The wrong paint system acts like a seal here, blocking the capillary conductivity of the clay.

To ensure that your substrate can continue to regulate moisture unhindered, you should match your choice of paint to the specific demands of the room. Here we distinguish between three proven systems, each with a different technical focus:

  • Lehmfarben: The most consistent solution for dry living spaces, preserving the mineral integrity of the wall build-up.
  • Kalkfarben: The first choice for areas exposed to increased moisture or wherever reducing the risk of mould is a priority.
  • Silikatfarben: Ideal for surfaces that require greater wipe resistance and mechanical durability.


Painting clay plaster with clay paints

Painting a clay plaster is one of the most beautiful tasks in building: this activity produces results very directly, and satisfaction with what has been created is foreseeable! It is an almost contemplative act in which the room is given its face.

Previously that, a lot of work, a lot of dirt and dust was necessary before a wall was finally ready to be painted. And a lot of thought was given to color shades and qualities: Which color is optimal for the substrate? How do the colors affect the room?

Of course, clay plaster harmonizes very well with clay paints. Our manufacturers produce them in a wide range of colors, ready-mixed in standard shades at the factory. If that is not enough variety for you, you can customize all the colors yourself with pigments.

The clay paints from the major clay building materials manufacturer conluto stand out for their quality and wide range of colours. You buy these paints as a powder, which you mix with water in portions as required.

We also stock other clay paints from the manufacturers Kreidezeit, Beeck or Auro. Every clay paint differs slightly in composition and application. The conluto clay paints, for example, are particularly well suited to machine application.

Alongside “classic” wall paints, there are also what are known as clay brush-on plasters. They are applied in a thicker coat than a paint, giving them a depth and three-dimensionality that can never be achieved with a coat of paint.
A finish of this kind has excellent filling properties and conceals uneven substrates well.

By mixing the clay brush-on plaster additive into the conluto clay paint, they are easy to make yourself. The Conluto clay brush-on plaster is available in a variety of colours: as standard there are 35 shades, which you can also mix with one another. The brush-on plasters can also be tinted with pigments to suit your own requirements.

Paint a clay plaster with lime paint? A wonderful combination!

Lime paints harmonize particularly well with lime substrates, but because of their diffusion-open character they are also suitable for painting clay plaster. Occasionally you should apply a priming coat with the right primer.

By the way, properly applied lime coatings do not rub off, although the opposite is a widespread and persistent misconception. Paint only chalks if it has not been applied correctly or if an inferior "DIY-store quality" product has been used.

Swamp lime paints cover well, adhere to all mineral substrates and are usually very easy to work with. The swamp lime paint from Hessler still stands out due to its very good quality.

All lime paints can be colored with quick lime pigments.

Beautiful surfaces can also be created with silicate paints when building with natural building materials. The plaster substrate for a silicate paint always contains silicon (lime, clay or lime-cement plaster). Silicate paints do not hinder the diffusion-based moisture transport within the wall, because they are free of film-forming substances and therefore also completely open to diffusion.

Its use in interiors on a clay plaster is particularly recommended for allergy sufferers and people with a sensitivity to chemical substances. Silicate paints do not emit any preservatives or solvents and are free from plasticizers and fungicides.
