Lime plaster for inside & outside - processing & prices

More and more homeowners are interested in what effects the building materials you use on their well-being and their impact on the environment.
The benefits of lime plaster

  • Lime plaster is completely produced without preservatives, plasticizers or solvents. Thus, the building material is completely emission-free, since no solvents are included. Because there are no organic substances, mold does not feed. What leads inside to healthy indoor air and is also an excellent choice for allergy sufferers, outside of the facade keeps our air clean.

  • Purity also brings lime plaster on the façade in a different way: Due to changed environmental conditions, facades are increasingly being attacked by fungi or algae in recent times. Water-repellent façade surfaces favor the deposits on which these organisms develop. Therefore, more and more hydrophilic surfaces are recommended today by the building physicists, who are open to diffusion and absorb and release moisture. This is a natural protection against contamination by fungi and algae, so that can pollute the environment
    Measures against these impairments are eliminated.

  • The façade with the lime plaster does not get dirty quickly because lime plaster is antistatic. It does not attract dirt particles from the air like other facade coatings.

  • Recent research has also discovered that lime plaster develops a natural self-cleaning effect as the surface progressively coats with crystals of calcium carbonate. The calcium carbonate (the main constituent of marble, by the way) creates a structure similar to a nano surface on the plaster. As a result, not only the rain is always better discharged, it will be superimposed even the smallest damage to the surface and gradually closed. This self-healing has been known for a long time from facades of historic buildings, with the first lime plaster systems for the private outer facade you could now benefit from it.

Conceived wall coating construction
In order to make the most of these advantages, however, a well thought-out wall coating structure is required anyway, so that cracks that have to heal themselves do not even arise in new buildings. Depending on the wall, the right flush-mounted surface must be selected, for example, there is a special, easy-care plaster that is tailored to the requirements of highly heat-insulating new building bricks.
These bricks require high diffusion openness, which does not offer very dense cleaning materials on the outside (synthetic resin plaster). The very vapor-permeable lime plaster is a good choice here. Also at
The insulation of low-energy and passive houses corresponds to the low vapor diffusion resistance of the right wall structure, as ideally the combination of mineral insulating materials with mineral plaster is considered here. In addition, lime plaster offers many design options, in addition to the usual structures and colors, the material can even be given a particularly fine surface by felting.
Lime plaster for interior
Green products are also in vogue on the inside, which is why lime plaster is increasingly becoming established on the wall. The number of allergy sufferers in Germany is constantly increasing, these people are dependent on a healthy, unencumbered indoor climate. Lime plaster is free of allergens, germs and other pollutants and also causes a moisture balance, it creates a healthy indoor climate for allergy sufferers. Also for the interior plaster there are many design possibilities, whereby even here a very smooth felt plaster is conceivable.
Lime plaster - color and coating
Lime render is usually applied uncoloured, only the top layer is colored with pigments. The natural pigments result in gentle, natural
beautiful colors. Matching pigments are available from the manufacturer and special suppliers of natural pigments, there are also ready-mixed lime plasters, which are already dyed by the manufacturer.
Especially for colored lime plaster facades as well as for other mineral plasters a Egalisationsanstrich is recommended, which should ensure the uniformity of the coloring. Whether such a not just cheap Egalisationsanstrich is really necessary, however, is highly controversial.
Lime plaster - prices

  • Lime plaster for the facade is mixed on the construction site. A 30 kg sack only costs about 8, - Euro, per plaster thickness of 10 millimeters you need about 13 kg per square meter.
  • Lime plaster for the interior convinces not only because of its good ecological properties but also because of its pleasingly low price; it is available in a 30 kg bag from just around 10, - Euros.
  • You need about 12.5 kg per square meter per 10 millimeter plaster thickness. However, lime plaster based on lime lime for the last (color) layer is today also sold ready for processing in the bucket, it can be tinted with the desired color by machine stirring.This finished variant is considerably more expensive, for 10 square meters you need around 18 kg, which costs around 80, - €.

Editorial tips

  1. If you have the plaster applied by a specialist company, the cost of the material comes from work that varies depending on the region. Since the working price depends significantly on whether several layers of plaster must be applied or the plaster is applied to an old wall surface with more or less repair work, here can result in a price between a few euros and a good double-digit sums for the square meter.
  2. Clay plasters and gypsum plasters, which especially give the inner walls a nice final coating, are also convincing with their natural ingredients.
