When processing concrete and screed surfaces, careful substrate preparation is of great importance. Uneven or dirty surfaces in particular require thorough preparation before they are covered with a floor covering or processed in any other way. A typical work step here is milling, which is used for both renovations and new buildings. Find out here how milling works, what purpose it serves and what advantages it offers.
How does the milling of concrete and screed work?
Milling means nothing more than the removal of material and this can affect an entire area as well as individual points in the ground. A prerequisite for milling is that the concrete has fully hardened. Tool rollers coated with hard metal or devices with rotating diamond segment discs are used as milling tools. These remove several millimeters of concrete from the surface when they are pushed across the ground. The amount of removal or depth can be set individually. Milled concrete can be recognized by the grooves on the surface.
What is the purpose of milling screed and concrete floors?
Milling is an important part of subfloor preparation because it serves important purposes: First and foremost, it can be used to remove bumps on the floor, such as small bumps in the concrete or a crumbly surface. Milling removes the uneven layer, leaving a stable, smooth floor onto which any floor covering can be attached. Attention: The massive processing of floors by milling can affect the statics of a building, so it is important to have such work carried out by a company specializing in this.
Even large areas of dirt (e.g. old tile adhesive, oil residue or paint residue) can be removed with a milling machine.
In addition to the large-scale removal of material to smooth and clean the floor, there is the option of using the tiller in a targeted manner at specific locations. Hand tools are usually used here, for example to remove protruding corners or mill slots in the concrete. These slots can be used to route pipes or cables through the floor or wall. Expansion joints can also be milled into the floor.
What advantages does concrete and screed milling offer compared to other methods?
Milling allows larger amounts of material to be removed, making it suitable for heavily damaged, very uneven or contaminated soil. Up to 3 centimeters of concrete can be removed during milling. This method is therefore also suitable for removing thick coatings such as polyurethane.
Since larger areas can be processed at once with the milling machine, this method is often faster and more effective than other methods. It also allows a finer finish than, for example, a jackhammer and is associated with less vibration.
In addition, only milling allows precise cuts to be made in the concrete or screed, in which cables or pipes can be laid.
Thanks to modern milling machines, which are combined with powerful industrial vacuum cleaners, the dust produced during milling is sucked up immediately, so that hardly any dirt can penetrate into the inhabited area.

Questions and answers about milling
No, in some cases it is sufficient to sand the surface, for example before plastering. Grinding is gentler on the material and does not require a new application of concrete. However, whether milling is necessary depends on many factors and must therefore be decided individually for each project.
The concrete or screed must be fully cured before milling work can be carried out. Depending on the type of screed, this can take up to 28 days.
With a milling machine, precise grooves can also be made in the screed later, into which the pipes for the underfloor heating can be laid. It is important that the correct distances are maintained when milling.
The costs depend primarily on the amount of work that results from the size and surface condition of the area. We would be happy to make you an individual offer for your project. Simply contact us, we look forward to hearing from you.
No, even if both terms are sometimes used synonymously, these are two different works. A concrete cutter gets deeper into the rock and removes more material than a grinder. In addition, it is possible to mill slots in the concrete, for example to lay pipes or underfloor heating.
Sanding, on the other hand, is gentler on the material and a good preparation for plastering. Grinding enables an aesthetically pleasing result, especially with fair-faced screed. In many cases, milling and grinding complement each other, so that the two jobs are carried out one after the other.
