Laying dry screed - This is how it succeeds in no time
Who reliably protects against falling walls or sheltering burglars, relies on a level, level and stable floor. This is where screed comes into play, which is commercially available as dry or wet screed. Unlike screed and cement screed, dry screed not only saves a lot of time during laying, but also scores points along the line with outstanding thermal properties and co.
Accordingly, it is particularly well suited for hobby craftsmen who like to work independently and without damage with the help of a costly professional - would like to receive a convincing result. However, before laying, the floor must first be prepared properly.
Advantages of dry screed
While liquid screed or conventional screed based on cement can dry much longer - sometimes even several weeks - dry screed is always suitable , When it should go fast. When laying the panels, self-proclaimed craftsmen can also look forward to user-friendly handling due to the special leveling compound. The required tools are either already available in the hobby cellar or can be easily obtained.
- Removal plate
- Spirit level
- Saw (circular saw)
- Cordless screwdriver
- Cutter knife or spatula
The individual elements can be opened directly a bed of mineral, porous grains are laid. These dig into each other, which allows high stability. The special dry bed is pleasantly light, does not burn, protects against heat loss and insulates against sound. In addition, the various screed elements such as gypsum fiber and perlite form a good insulating material. Under pressure, the individual compo- nents of the slabs are also thickened, so that the result is a very stable and very resilient floor.
Further Advantages of Dry Screed Slabs
Dry screed is particularly suitable for drywall construction - for example the Loft conversion - suitable. By laying screed, bumps can be removed.
In contrast to liquid screed, which is comparatively heavy due to its high water content and carries the risk of collapse, dry screed scores lower points due to its lower moisture content Mass. An integrated sound insulation ensures not least the reduction of step noise in higher floors. In addition, dry screed can be walked on immediately after laying, so that subsequent work can be carried out promptly.

Step 1 - Prepare the Underground
Before laying the screed, the subfloor must be dry, clean and stable. In order to prevent the formation of mold later, it is advisable to lay a vapor barrier - a vapor-impermeable film - on the prepared floor. This protection should be fixed with an adhesive tape or special adhesives to avoid damage and to guarantee a mildew-preventing effect. Accordingly, do not use any nails and do not staple the vapor barrier.
For optimized sound insulation, it is advisable to attach edge insulation strips to all rising components. As a result, contacts and sound bridges are avoided, which can reduce the insulation. A self-adhesive quality ensures a simple and fast handling.
Intermediate step for a plank floor
If the dry screed is to be laid on wooden floorboards, it makes sense initially to apply a trickle protection so that the leveling compound can not trickle through gaps, cracks or holes. This additional step is especially recommended for old planks. A special foil, fleece or special paper is laid over the floor and pulled up against the walls. A moisture-proof trickle protection can also serve as a vapor barrier and prevents moisture damage on warm-cold transitions.
Step 2 - A correct leveling
First, the soil is divided into individual plots with a width of 20 centimeters. The individual plots are bounded with battens before they are filled to the edge of the roof batten with the leveling compound. The surface is smoothed with a peel-off plate, which should under no circumstances remain in the leveling pad.
To ensure that the surface is level, it should be checked with a spirit level. The uneven surfaces of the ground should be at least one centimeter high. If the bumps are larger than one centimeter, a high density Fermacell leveling pad should be used.
Now the roof battens are removed, the resulting grooves are filled up and removed with the peel plate. Before laying the screed, check once again whether the substrate is really even.
The leveling compound should never be entered without a cover, otherwise the surface will become uneven again. Reduce impact and airborne noise: apply to high density screed elements such as Fermacell as additional insulation apply high density mineral wool under the panels as described add self adhesive edge insulation strips to decouple the sound.
Step 3 - Lay the screed plates
Now follows the actual main step. If the plates still need to be cut, a hand-held circular saw is particularly suitable. The screed should be laid on the wall opposite a door. The adjacent screed panels are first glued with screed adhesive. The adhesive is applied to the shiplap, preferably as a double adhesive cord. Afterwards, the panels are secured in the area of the rebate rebate using corrosion-resistant drywall screws, preferably with a cordless screwdriver.
The dry screed elements can alternatively be replaced by OSB panels as a natural material, which can also be laid directly on the leveling floor. The OSB panels score well with good environmental performance, good thermal insulation properties and can even be used directly as a final floor covering - for fans of a purist, rough flair.
Resistant Fermacell gypsum fiber boards are again based on recycled paper, gypsum and water be pressed without additional binder under high pressure to odorless, robust plates.
Step 4 - Apply the floor covering to the dry screed
After a drying time of approx. 24 hours, residues of the adhesive or leaked adhesive can be removed with a craft knife or a spatula - to be removed. Simply apply the desired floor covering to the screed panels.
Lay screed panels at a glance:
- Prepare the floor
- Lay the vapor barrier
- Install the sound insulation
- if necessary, apply a trickle protection
- Divide the floor into parcels
- Integrating roof battens
- Attaching leveling compound
- Smoothing leveling compound
- Laying screed plates
- Drying screed
- Laying floor covering
Dry screed can be laid in a user-friendly way and scores high with numerous advantages, which make it especially for hobby craftsmen a recommendable product. This ensures that the ground becomes straight, even and stable. In contrast to wet screed, dry screed can be processed quickly and covered with a floor covering in a timely manner.
