Screed as a screed

For many years, screed was only a substrate, a floor covering was always laid on top. Only in recent years is there more and more the trend to use the visually interesting screed as (minimalistic and robust) flooring.

In professional jargon, something like that means "visual screed". Visible screeds are equipped with a suitable seal, quite robust floors that need little care and last very long. Anyone who wants to save an extra floor covering, goes quite well with Sichterstrich.

Requirements for screed

Screed is not the same screed. Every kind of screed has its special characteristics and its advantages and disadvantages. The hardness of the screed is not the same for every type of screed.

Anhydrite screed by nature has a slightly lower hardness than classic cement screed. As a subfloor, this is usually not very important, but if the anhydrite screed is to be used as a screed, it must be taken into account during installation. The screed layer must then plan the screed with a correspondingly higher hardness.

In principle, anhydrite screeds are just as suitable as a screed if you are designed for it.

Proper degree of humidity

Further processing of the screed to the visible screed may only be carried out when the required residual moisture has been reached. This must be determined in any case by a measurement.

Measurements are not non-destructive - in order to obtain a meaningful measurement result, a hole must always be drilled in the screed. Ab Sanding the screed

Before you can make a screed from the anhydrite screed, you have to sand the surface after hardening. The sintering layer on the surface must be sanded off in any case, as well as the usual priming of the anhydrite screed.

Coating the surface

Only materials that give a completely dense surface are eligible for the coating. As a rule, these are

Epoxy resin coatings

PUR coatings

  • Wax coatings (less advisable)
  • However, care must be taken to ensure that the manufacturer actually approves them.
  • Tips & TricksWax coatings can be problematic. Anhydrite screed is highly absorbent and has a major moisture loading problem. This must be taken into account in any case, and the screed sufficiently protected from moisture.
