Professional surface preparation by grinding with polycrystalline diamonds in Hamburg and Germany
The preparation of the substrate plays a central role when it comes to preparing floors for a new coating or renovating them. Whether old epoxy resin coatings or old coverings need to be removed or the sinter layers of newly laid concrete or screed floors need to be ground off – sanding with polycrystalline Diamond tools have proven to be the most effective and gentle method.
Mit dieser Technik werden Altbeschichtungen durch ein präzises und kontrolliertes Verfahren entfernt, das den Untergrund minimal belastet. Dies ist besonders wichtig, um den dauerhaften Verbund zwischen dem Boden und der neuen Beschichtung zu sichern. Das Ziel jeder Untergrundvorbereitung ist es, eine möglichst hohe Haftzugfestigkeit der Oberfläche zu erreichen.
Why grinding with polycrystalline diamonds
in the preparation of the substrate?
Compared to other methods such as shot blasting or milling , which often cause more damage to the floor surface, grinding with diamond tools is a particularly floor-friendly solution. The diamond grains cut into the floor surface and remove material precisely and evenly. Grinding leaves a smooth but slightly rough surface that is ideal for further processing.
Especially when renovating floors and removing epoxy resin coatings or adhesive residues from carpets, sanding ensures a uniform result without major effort in post-processing. In addition, there is no need for complex roughness leveling , as sanding creates a flat and level surface.
Advantages of grinding with polycrystalline diamonds
Gentle on the floor: Sanding is a gentle process that evenly treats the surface without damaging it.
Economical: Since work steps such as roughness leveling are eliminated and drying times are minimized, the process is particularly time-saving.
Versatile: Whether it is about removing old floor coverings, tiles, carpet adhesive residues or working on concrete or screed floors - sanding is the ideal solution.
Dust-free: In combination with powerful vacuum cleaners, sanding ensures a virtually dust-free working environment.
Professional grinding machines for best results
In order to achieve optimal results in the preparation of the surface , modern three- or four-disk grinding machines with planetary gears and diamond tools are used. These machines ensure that the surface is processed evenly and precisely. The use of these machines achieves a high level of efficiency, particularly on large surfaces.

When is milling the better choice for subsurface preparation?
Manchmal ist das Schleifen bei der Untergrundvorbereitung nicht ausreichend. In diesen Fällen, wie bei stark verölten Betonböden oder mit Chemikalien kontaminierten Estrichflächen, kommt das Fräsen zum Einsatz. Diese Methode entfernt tiefer liegende Schichten des Betons. Allerdings ist das Fräsen nur in Ausnahmefällen zu empfehlen, da es den Beton stark belastet und die Nachbearbeitung aufwendiger ist.
Conclusion of the subsurface preparation
Grinding with polycrystalline diamonds is the ideal method for effective, gentle and economical surface preparation. It offers consistent results, minimizes material removal and reduces rework.
