Before any resin, paint or coating, surface preparation determines the bond. Sept Tools links the three techniques in a dedicated brushless range, made in Roanne.

Concrete surface preparation is the step that determines how well any coating holds: epoxy resin, technical paint, poured floor, waterproofing or bonded tiling. Poorly prepared concrete means delamination in the end. Three techniques cover most concrete surface treatment: grinding (opening and evening out the material, removing laitance and old coatings), planing (removing glues, resins, markings and excess thickness over a few millimetres) and bush hammering (creating a mechanical CSP 5 to 7 relief for resin bonding and non-slip finish). Sept Tools brings these three families together in a brushless range dedicated to surface preparation, made in Roanne: Tapir on floors, Gazellomur on walls, Petit Potam and Fouine XB165 for grinding, planing and bush hammering. One philosophy: repeatable grain, native strain reduction, class H extraction.
The machines below are selected for this application: dust captured at the source and anti-MSD design. Quote within one working day.

Compatible with the IU33 Longopac, a Sept Tools vacuum declared as class H. Built and assembled in France.
The Petit Potam XM165 is our compact concrete wall grinder for surface preparation, paint removal, raw concrete grinding, plaster, adhesives and resins. Brushless 1600 W motor, vibration of 0.35 m/s² measured at the handle and declared in the user manual, 59 dB(A) on occupied job sites.

The Fouine XB165 is our versatile wall and ceiling grinder, designed for renovation, construction, demolition, asbestos abatement and dismantling. Brushless 1600 W motor, 0.35 m/s² vibration, 60 dB(A), IP65. Mounted on a Gazelle or Eland trolley, it grinds concrete ceilings without holding the machine overhead. Ø165 disc for grinding.

Clean preparation on occupied sites, in enclosed spaces or in sensitive zones.
We identify the condition of the concrete (laitance, glues, old coatings, flatness) and the CSP profile required by the technical data sheet of the coating to be applied. This diagnosis determines which technique to use: grinding, planing, bush hammering, or a combination.
If the concrete carries glues, resins, thick paints or excess thickness, planing with the Gazellomur removes them over the first millimetres, dry, with source extraction. We return to sound concrete.
Grinding with the Tapir (floor) or with the Petit Potam and the Fouine (wall, ceiling) opens the laitance, evens out defects and prepares a uniform surface. It is the basic step before paint, thin coating, or before bush hammering.
For a demanding coating (epoxy, poured floor), bush hammering with the Bouchardeuse Fouine XB165 or the Gazellomur Bouchardage creates the bonding relief. The mechanical profile is uniform and repeatable across the whole surface.
Complete class H vacuuming to remove the residues of each pass, visual check of the profile and of the uniformity of the grain. The concrete is ready to receive the coating under the manufacturer's warranty conditions.
1. Diagnosis of the substrate and the coating
We identify the condition of the concrete (laitance, glues, old coatings, flatness) and the CSP profile required by the technical data sheet of the coating to be applied. This diagnosis determines which technique to use: grinding, planing, bush hammering, or a combination.
2. Stripping and planing of contaminants
If the concrete carries glues, resins, thick paints or excess thickness, planing with the Gazellomur removes them over the first millimetres, dry, with source extraction. We return to sound concrete.
3. Grinding and levelling
Grinding with the Tapir (floor) or with the Petit Potam and the Fouine (wall, ceiling) opens the laitance, evens out defects and prepares a uniform surface. It is the basic step before paint, thin coating, or before bush hammering.
4. Bush hammering and creating the bonding profile
For a demanding coating (epoxy, poured floor), bush hammering with the Bouchardeuse Fouine XB165 or the Gazellomur Bouchardage creates the bonding relief. The mechanical profile is uniform and repeatable across the whole surface.
5. Final dust removal and check
Complete class H vacuuming to remove the residues of each pass, visual check of the profile and of the uniformity of the grain. The concrete is ready to receive the coating under the manufacturer's warranty conditions.
Concrete ground too lightly or polluted by laitance does not offer the bonding profile required: the epoxy resin blisters then peels.
Mechanised bush hammering with the Bouchardeuse Fouine XB165 or the Gazellomur Bouchardage creates a repeatable relief across the whole surface, to be adapted to the resin manufacturer's requirements.
Grinding clogs the abrasive on glues and thick resins without lifting them, wasting time and consumables with no clean result.
Planing with the Gazellomur Rabot or the Rabot Castor attacks the concrete over a few millimetres and tears off glue, residues and excess thickness, with source extraction.
Concrete surface preparation generates crystalline silica: without capture, the 0.1 mg/m³ OEL is exceeded and the occupied-site jobsite becomes impossible.
Every Sept Tools machine connects natively to class H (HEPA) extraction that captures dust at the source. Work in an enclosed space, a hospital or an operating shop becomes possible again.
Conventional preparation machines tire the operator: high vibration, weight carried at arm's length on walls and ceilings, hence MSDs and repeated sick leave.
Sept Tools gantries, compensators and trolleys transfer the weight of the machines, and vibration is that declared in the manual of each machine. The operator keeps the pace over a full day, with less effort.
Chaining stripping, grinding and bush hammering with a different machine for each step multiplies rentals, logistics and setting times.
The Gazellomur is a single carrier with interchangeable heads: grinding, planing and bush hammering.
Before an industrial epoxy resin or a high-performance poured floor, bush hammering creates a mechanical relief, to be confirmed with the resin's technical data sheet. Before a floor paint or a thin coating, grinding is enough to open the laitance and offer a sound surface. To remove an old glue, a residual resin or a marking, planing acts on the first few millimetres. The rule: the thicker and more demanding the coating, the more marked the surface profile must be.
Grinding removes surface laitance and thin old coatings and evens out flatness defects. On floors, the Tapir covers large areas with a good output rate on concrete; on walls and ceilings, the Petit Potam and the Fouine XB165 handle vertical zones and soffits. It is the basic step of any preparation before paint or thin coating.
Planing (or milling) attacks the concrete over a few millimetres to remove what grinding does not lift: old tile glues, resin residues, thick paints, floor markings, levelling compound excess. The Gazellomur Rabot, the Ceiling Planer, the Rabot Castor and the Écureuil handle these mechanical stripping jobsites with source extraction.
Bush hammering produces a controlled relief, to be adapted to the requirements of the resin or industrial floor manufacturer. On floors, the Bouchardeuse Fouine XB165; on walls, the Gazellomur Bouchardage or the set with the Bouchardeuse Potam. It is also the technique for non-slip finishes and for heritage renovation revealing the aggregates.
