The interior plaster does not dry? That's how it works


When drying the interior plaster, there are often uncertainties. How should be dried or why the plaster does not dry? What you have to consider when drying the plaster, you will learn in this post.

What factors prevent drying?

  • Drying times are misjudged
  • Drying times are not matched to the plaster used
  • It is not ventilated properly
  • The temperatures are too cold or too hot

Which drying time does a interior plaster require?

For the interior plaster usually a lime-cement plaster is used. The drying depends on several factors. One distinguishes between drying time, plaster thickness, temperature and the correct ventilation.

What are drying times?

A plaster can be smoothed only when he has "dressed", so already dried out a bit. To estimate this as a non-professional, there are a few rules of thumb:

  • the plaster is then suitable for smoothing, if you can barely press it with your finger.
  • Trituration must not cause dents or cavities
  • If the surface is already too dry, the plaster will sand

Which plaster dries how long?

Of course, the drying also depends on the layer thickness. The rough guideline is 1 day per millimeter layer thickness. If multi-layer plasters are processed, even more time must be expected. The higher the lime content in the plaster, the longer the drying time, the plaster content in the plaster is high, it shortens. In general, a plaster is completely dried out in 14 days

How to ventilate?

The principle of airing is quite simple:

  • Remove humid air from the room by venting
  • let dry outside air into the building
  • The air saturates very well with moisture when heated.
  • Repeat procedure

What should be considered at high or low temperatures?

Never clean at below 5° C and above 30° C. Whether you need to ventilate your interior plaster in summer or in winter, you must pay attention to this:

  • Warm air in summer can not absorb much moisture. Then only air at night
  • Cold air in winter is dry. Warm them up and replace them with cold air using air venting
  • Do not ventilate in damp weather

Tips & Tricks

If all measures do not work, only the building dryer remains to regulate the humidity.
