All screed floor structures - Overview of cross-sections
Would you like to install your screed yourself? Then it is important to have a good foundation. Your screed must lie perfectly in order to place your floor finish correctly. There are different types of screed, such as cement-based screed and gypsum-based screed. The composition of the screed usually consists of sand, cement and water.
Nowadays you can easily lay screed yourself, even if you have no experience with the Staenis slat system. This system makes it easy to maintain the correct height of the screed and ensures that you do not have to worry about the end result.
Once the Staenis grid has been set correctly, you should not take the height into account when scraping the screed. As a result, the most difficult task disappears and you can fully focus on feeding, compacting and scraping the screed.
If the screed works are not fully completed within 1 day, you can always continue screeding at a later time, without any time pressure.
The risk of cracks, collapse, loosening, etc. of the floor is negated by dividing the floor structure into very small fields of 0.25 m². The grid ensures that you do not have to worry and that you will achieve a correct, high-quality end result.
For large surfaces, you can save on a decoupling mat (30 euros/m²) with the Staenis grid. View the technical advantages for this.
When using the Staenis grid, you no longer need to place expansion joints, except at the opening of a door. Edge insulation is still necessary around the screed. In addition, you must apply a waterproof foil before placing the screed.
Applications
Small spaces: You are always cheaper, in spaces smaller than 40m², by installing your screed yourself with the Staenis grid.
Large spaces: The Staenis grid with screed protects your tiles. You almost no longer have to place expansion joints and an uncoupling mat is unnecessary.

Easy to lay your screed yourself, even without experience
Laying screed yourself is a lot easier with the Staenis grid. During damming and levelling, you can easily follow the height reference points (screed bars or screed guides) of the reinforcement grid, so that your screed will lie nicely flat. Once the Staenis grid has been set correctly, you do not have to take the height into account when pouring the screed. This way you can fully focus on laying, compacting and polishing the screed. The wheelbarrow structure divides the screed tensions, so that you always get a top-quality end result. And you also don't have to screed a large area in one go. If the screed work is not finished in one day, you can continue screeding whenever it suits you. Choose your floor structure from the list above and view a tailor-made manual for laying screed.
Laying the screed yourself with the Staenis grid = saving
By laying your screed yourself with the Staenis grid, you are guaranteed to obtain a professional result, and you can also make considerable savings. You save enormously, especially on small surfaces, because you will not be charged a fixed price by a screeder. With large surfaces you also save on a decoupling mat, a saving of 30 euros per m² on average. Furthermore, with the Staenis grid you do not need a steel reinforcement mesh to lay your screed. Also, when you work with the Staenis grid, there is automatically an expansion joint in your floor every half metre. This means that it is not necessary to place a real expansion joint in the screed and in the tiles.
Make your own screed: add water
Adding water to the sand-cement mixture is a crucial step to obtain a good screed. It is important not to add too much water at once, as this can lead to a wet and weak screed. Gradually add the water, while continuing to mix the mixture well. Make sure the mixture forms a good slurry that is neither too wet nor too dry.
Screed drying time
The drying time of screed depends on various factors such as the thickness of the screed, humidity and ambient temperature. In general, it takes about 1 week per centimeter of thickness before the screed is dry enough to install a floor finish. It is important to allow the screed to dry thoroughly before proceeding with the installation of tiles or other floor finishes. A screed that is too moist can lead to problems such as loosening of the tiles, mold formation, or other moisture problems.rel=0&enablejsapi=1&origin=https%3A%2F%2Fwww.staenis.com" allow
Screed and underfloor heating
When installing underfloor heating in combination with screed, there are some additional points for attention. Make sure that the underfloor heating elements are properly fixed and that they cannot move during the installation of the screed. It is also important to make the screed sufficiently thick on top of the underfloor heating, so that the heat is distributed well and the underfloor heating works efficiently.
Conclusion
Making and installing screed is an important part of the floor structure. By using the correct proportions of sand, cement and water, and taking into account the drying time and any underfloor heating, you can ensure that your screed forms a solid and even base for your floor finish. The Staenis slat system makes laying screed easier and more accessible, even for people with no experience.
