Restoration plaster or lime plaster - what is better?


Restoration plaster is considered the remedy for damp and salty walls. But also lime mortar or lime plaster offers advantages. It contains no harmful salts, cement or other materials that can cause blooming on the brickwork. He is also significantly cheaper than special restoration plaster.

The properties of restoration plaster

Restoration plaster is usually used to assist the drying of damp walls after the removal of the causes. It is a water-repellent and open-pored material that helps you to process it very easily and helps to eliminate your moisture problem on interior or exterior walls. The harmful salt efflorescence also helps to effectively prevent restoration plaster. However, it should not be concealed that the material can sometimes contain a lot of chemistry. Therefore, many people swear on lime plaster as an alternative, which can have quite similar properties and which you can also use in certain areas.

Lime plaster as an alternative to renovation plaster

Many people refer to lime mortar or lime plaster as the better restoration plaster, since moisture contained in the masonry can dry out unhindered to the outside, and much faster than, for example, cement mortar. Lime plaster contains no harmful materials that can promote efflorescence and cracks like other materials. It only depends on the correct processing and on the fact that the material is tied during a frost-free time. For old masonry lime plaster is considered a very gentle solution. Since water and salt solutions from the underground in lime mortar can penetrate unhindered, it is also very well as a so-called sacrificial plaster. He is also very cheap.

This is how lime works as a building material

Lime can act like a sponge. So it is able to absorb a larger amount of moisture, which can be an advantage for you. There are numerous small pores that fill with moisture. The moisture remains in these pores until the humidity in the room decreases again. The material thus ensures a regulation of the room climate. In addition, the material has other important properties:

  • Lime plaster helps to reduce pollutants and counteracts mildew because it is highly alkaline.
  • Thanks to its moisture-regulating effect, it also ensures a pleasant indoor climate.
  • For lime plaster, there are a large number of different top coats with fine or coarse textured surfaces.
