anhydrite screed or cement screed? The pros and cons

When it comes to choosing the right screed, you always have to weigh up the advantages and disadvantages. Often you have to make a decision between anhydrite and cement screed. Our contribution offers a little help in making decisions.

Disadvantages of anhydrite screed

Anhydrite screed has one major disadvantage: it is very sensitive to moisture. An egg set in damp rooms or with potential moisture is therefore not recommended. These are rooms like:

  • Baths
  • Toilets
  • Laundry rooms
  • Basement rooms

In such rooms there is a risk that moisture will penetrate the screed and destroy it. It must be avoided at all costs.

In all rooms in which moisture plays a role, cement screed should definitely be installed.

Setting time

Anhydrite screed hardens much faster than cement screed. Extracting is an advantage wherever it can be installed particularly quickly. The time until hardening is usually around 7 years with Anhydriesrich

With cement screed, in most cases you have to wait around 30 days before it is ready for covering. In the case of large areas and problematic soils, this can take a few days longer.


Cement screed is much more resilient than anhydrite screed. It is the material of choice, especially for medium and high loads. Anhydrite, on the other hand, is more suitable for light loads and less stressed areas.

Post-processing and effort

When it comes to the amount of work involved in finishing, the anhydride screed also has some disadvantages: it must be sanded after installation so that a later floor covering actually adheres to it. In addition, an effective seal must be installed to protect the screed from moisture.

All in all, anhydrite screed is also slightly more expensive than traditional screeds. This is mainly due to the high effort involved in processing and the time and effort involved

Advantages of cement screed

Cement screed is highly resilient, can be used in all areas (including outdoors) and has a long service life.., The strength of cement screed is also significantly higher., w makes. as it can also be used for heavy loads

Tips & Tricks A flat-rate recommendation for a screed type you can never give - many depends on the local conditions. The moisture sensitivity of anhydrite and the robustness of cement screed will be the main argument in most cases
