Reasons and techniques for surface smoothness

For the desire to make a lime plaster inside with a completely smooth surface, speak aesthetic and practical aspects.

  • Color pigments (up to a maximum of ten percent of the plaster volume)
  • Glitter and mica
  • gold

In the plaster mortar defined according to European and German standards lime plaster is divided into three groups:

  • Luftkalkputz
  • Wasserkalkmörtel
