Surface preparation: a transversal trade
The surface preparation specialist is the transversal trade in construction. Where the asbestos remover, the carbon strengthener or the polished concrete craftsman are specialists, the surface preparation specialist must know how to do everything: prepare an industrial floor for epoxy resin, remove laitance before tiling, open a surface for repair mortar, polish polished concrete, strip paint on bare concrete. The trade requires equipment versatility that no other construction market demands.
Sept Tools has become the natural partner of these companies for a simple reason: our range covers every preparation method with a unique logic of brushless manufacturing, interchangeable 165 mm discs and shared anti-fatigue accessories. A surface preparation specialist who equips their fleet with Sept Tools no longer has to juggle four different brands depending on jobsites.
Covering every CSP profile
The ICRI (International Concrete Repair Institute) classifies concrete surface profiles on a CSP 1 to CSP 9 scale, from smoothest to most open. Each type of future coating requires a precise target profile:
CSP 1 to CSP 2 for thin coatings (paint, varnish, fine resin under 1 mm): grinding with resin grit 200 to 400 disc.
CSP 3 to CSP 4 for medium resins (1 to 3 mm): grinding with metal grit 30 to 60 disc.
CSP 5 to CSP 6 for thick resins (3 to 5 mm): shot blasting or light bush hammering.
CSP 7 to CSP 9 for repair mortars and thick bedding mortars (5 to 15 mm): aggressive bush hammering or scarifying.
The Sept Tools range covers the entirety of this scale. The Petit Potam, Tapir and Fouine XB165 grinders treat CSP 1 to CSP 4. The Potam, Fouine and Gazellomur bush hammers cover CSP 5 to CSP 9. The Castor Planer completes for aggressive operations on large surfaces. A unique chain, a single after-sales, a single parts logistics.
Upstream diagnosis: a Sept Tools service
Before tackling a preparation jobsite, diagnosis is essential. You have to know the concrete hardness, its carbonation state, any contamination, surface flatness and the planned future coating type. Sept Tools trains its sales team to support specialists on this upstream phase. Our engineers visit jobsites to advise on the method, disc grit, expected productivity and the right equipment configuration.
On structurally critical jobsites (carbon strengthening, hazardous product retention, classified industrial floors), we also provide pull-off cohesion measurement protocols. This service approach is appreciated by inspection bodies that demand precise traceability of operations.
Mastering crystalline silica
Silica is the big topic for surface preparation specialists since 2017. The OSHA permissible exposure limit is 0.05 mg/m³ over 8 hours, and the EU directive 2017/2398 sets a binding limit of 0.1 mg/m³. No surface preparation jobsite can be considered without adapted extraction. Sept Tools offers two response levels:
The IU33 Longopac class H covers most preparation jobsites up to 800 m². HEPA H13 filtration, 65 l/s airflow, sealed continuous bagging.
The Turbo7 takes over for larger jobsites (1000 to 5000 m² in one phase) with higher airflow (70 l/s minimum) and the capacity to power two tools simultaneously via a Y splitter. Ideal for two-operator parallel configurations.
All our grinding, bush hammering and scarifying tools are equipped as standard with vacuum connectors compatible with both models. No adaptation, no specific connector, no time wasted in logistics.
Anti-fatigue as a professional standard
Surface preparation specialists are among the construction trades most exposed to MSDs. Constrained postures, overhead ceiling grinding, load handling, repeated hand-arm vibrations. Sept Tools has integrated anti-fatigue in every phase of its range: Gazelle and lift support for ceiling grinder carrying, Eland for long grinding sessions, Scourpio for arm relief at height, low-vibration discs to limit hand-arm transfer.
A surface preparation specialist equipped with Sept Tools sees their MSD absenteeism rate drop 30 to 50 % over two years, measured by our clients on fleets of 10 to 30 operators. It is the hidden ROI that often exceeds the immediate productivity gain.
A quality approach at every step
In this trade, execution quality is non-negotiable. A preparation defect translates into failure of the future coating, and responsibility always falls on the preparer. Sept Tools provides as standard the elements that secure this responsibility: CE certificates, detailed technical sheets, measurement protocols, free training at fleet delivery, upstream support on complex jobsites. It is this service approach that has made Sept Tools the reference partner of professional surface preparation specialists in France and increasingly in Europe.
