Exposed screed as a modern floor covering: advantages, disadvantages, laying

What is fairing screed?

Screed refers to the part of the floor that serves as an underlay for the floor covering. As a rule, tiles, floorboards or parquet are laid on the screed. In the case of exposed screed, however, the screed is only sanded, provided with additives and used as a floor.

With its soft mass, the screed evens out unevenness in the load-bearing floor. The best-known variant is the cement screed, a special concrete mix; But also mastic asphalt screed made of chippings, sand, bitumen and stone powder or anhydrite screed made of calcium sulphate are used in houses, while magnesia screed has only established itself for special industrial use. The exposed screed is a special type of screed that does not require any additional floor covering. You can read in the following what advantages it offers in detail, what are the disadvantages and what has to be considered when laying fair-faced screed.

What are the advantages of fair-faced screed?

The two main advantages of exposed screed are that low maintenance and the long durability. A fair-faced screed floor is very easy to clean as there are no joints. It is also possible to color it without any problems and thus give the room an individual touch. There are no limits to creativity, and bright colors such as blue and green are increasingly popular. In addition, underfloor heating can be easily laid under the exposed screed, as the material conducts heat well and is resistant.

What are the disadvantages of exposed screed?

The simple look of the factory-style design is decisive for the success of exposed screed as flooring. However, there is also a disadvantage here: the industrial look can sometimes appear monotonous. In addition, the final appearance depends crucially on the skill of the installer. Another problem of screed can be the long drying time which is up to 30 days. The exposed screed floor must not be loaded during the process, otherwise cracks may form. Rapid screed is available on the market. It is a variant that hardens within minutes. The costs for this are four times as high as with conventional screed.

How can you design rooms with exposed screed?

Regardless of whether it is matt or glossy, colored or gray, exposed screed offers a lot of design freedom thanks to its mineral properties. In addition to the cool concrete look, many patterns and tones are possible, for example a granite or a salt-and-pepper look through the clever use of colors.

For which rooms is fair-faced screed suitable?

Exposed screed suits every room, whether it is a bathroom, kitchen or bedroom. Moisture and splashes of fat are not a problem as long as it is sealed. The seamless floor is particularly suitable for angled rooms where laying carpet or parquet is difficult.

What color should the screed be?

Gray screed, the classic par excellence, goes best with a minimalist style. The industrial loft look is classy and sober at the same time. Valuable armchairs, chairs and cupboards are upgraded, and it cuts a fine figure both in classically furnished rooms and in combination with pastel or strong tones. An experienced floor layer can, however, add color pigments to the exposed screed and create a cobalt blue, olive green or carmine red floor. Calcium sulphate screed is suitable as a designer screed because of its robustness. Not only different colors, but also marbled or grained patterns can be designed. The skill and experience of the floor layer decide on the result. For a successful execution, it is therefore advisable to contact a specialist.

Is exposed screed suitable for underfloor heating?

Even if you have a Underfloor heating plan, exposed screed is an optimal choice for the floor covering. If heating pipes run under the screed, one speaks of Heating screed. They are either embedded in the screed or placed under it or in a so-called leveling screed. In both cases, calcium sulphate or cement screed achieve good heat emission values. The flow temperature of the heating must not exceed 55 ° C on average, which is seldom the case with underfloor heating. Because of the expansion of the material due to the heat, it is important in this case Movement joints plan so that no cracks form in the floor. For this reason, an experienced floor layer should deal with the planning of heated screed.

Is exposed screed also suitable for outdoor use?

Exposed screed can also be used as a floor covering on outside stairs or in the garden. However, care should be taken to use a material that is insensitive to moisture. Cement and mastic asphalt screeds are particularly suitable for this, while anhydrite and magnesia screed can quickly lead to moisture damage.

How is exposed screed laid?

With exposed screed, a distinction is made between dry and wet screed. The former is laid from finished elements, the latter is spread as a moist mass on the sub-floor. In the case of floating installation, there is a layer under the screed that serves as heat and sound insulation, as well as a moisture barrier, which is particularly important in living rooms. The screed is also separated from the wall by edge insulation strips. This type of laying is preferred for houses.

First the tiler attaches the edge insulation to the wall, then he lays the foam or styrofoam panels as insulation. A plastic cover sheet is stretched over the plates, which serves as the substrate for the liquid screed. After the mass has been mixed with a concrete mixer, it is distributed with a shovel. The height is around 4.5 cm. The screed is drawn with a screed and a spirit level, then smoothed with a float. Then the craftsman lets the screed dry. The drying times differ significantly here. If normal cement screed needs up to 30 days before it can be used, only a few hours are sufficient for quick screed.

Do you have to sand exposed screed?

After the screed has dried, it is usually sanded. This is necessary to prepare the sealing, which in turn protects the floor from grease and other dirt.

Is the exposed screed sealed?

If screed is used as utility screed, it must be sealed in order to form a dirt and dust-repellent layer and to make the floor more slip and step resistant. Epoxy resin and polyurethane, but also natural materials such as rubber or latex, are available for this. The professional craftsman makes sure that the floor is smooth and clean before applying the sealer.

Can you lay exposed screed yourself?

Anyone who wants to lay exposed screed should have both the right tools and the necessary know-how. The application proves to be the most difficult. If the layer is not pulled smooth, bumps and cracks will appear in the floor. Mixing can also be problematic if the installer does not have sufficient experience and does not consider the correct mixing proportions. A high-quality sanding machine should be available for sanding the exposed screed after it has dried. Here, too, a specialist guarantees professional results. In principle, it is theoretically possible to work with exposed screed yourself. Overall, however, it is advisable to contact a specialist company to avoid unpleasant surprises.

Exposed screed is enjoying increasing popularity as a floor covering. The elegant look, the robustness and the long durability speak for it. In many cases, utility screed can also be laid without joints. If underfloor heating is desired, exposed screed offers a good basis because of its good thermal conductivity. In addition to the simple, gray look, many color combinations and designs are possible, but the final price is higher than the classic look.
