Wall planing is the aggressive vertical stripping operation that takes over when grinding is no longer enough: thick degraded renders, old tile adhesives, accumulated industrial paints, concreting steps to be corrected. Sept Tools offers two brushless solutions dedicated to wall planing and concrete scarifying, each acting as a vertical concrete scarifier for the densest substrates. The Écureuil with its two interchangeable drums (electrolytic for concrete and reinforced concrete, PCD for renders, bituminous coatings and resins) covers the bulk of needs. The Gazellomur 3-in-1 combo takes over on large surfaces with built-in strain relief. Key positioning: Sept Tools wall planing relies on attack force, not on feed speed.

Your questions, answered
Écureuil or Gazellomur: when to choose which?
The Écureuil with its two drums covers 90% of wall planing needs, in particular targeted stripping and small to medium surfaces. The Gazellomur 3-in-1 combo takes over on large continuous surfaces thanks to its built-in strain relief.
Electrolytic or PCD drum: how to choose?
Electrolytic drum for concrete and reinforced concrete: robust attack on dense substrates. PCD drum (polycrystalline diamond) for renders, bituminous coatings, resins and epoxy finishes: clean cut without tear-out. Drum change takes under two minutes.
Why is planing positioned for force and not speed?
Wall planing is the stripping operation for thick and dense substrates. A feed that is too fast reduces the depth of attack and prematurely wears the drum. The Écureuil and the Gazellomur are designed to maximise the applied force, even at the cost of slower advance.
Does the planer damage the concrete substrate?
No, provided the cut depth is set correctly. The drum stops on healthy concrete. Sept Tools provides the setting procedure based on the thickness of the coating to remove.
Can planing and grinding be chained on the same site?
Yes, the Gazellomur is a 3-in-1 combo (grinding, bush hammering, planing). The operator changes drums in under two minutes. For the Écureuil, planing is followed by grinding with the Petit Potam or Gazellomur Ponçage depending on the targeted finish.
