How long will your floor, wall or ceiling grinding job take?

Enter your surface and substrate to get an estimated jobsite time with an adapted Sept Tools machine, based on official throughput measured in real jobsite conditions. No invented figures: where a sourced manual comparison exists, it is shown too.

Your jobsite data

Enter your surface and your substrate

The calculator applies the official Sept Tools throughput measured in real jobsite conditions (the same figures shown on our floor, wall and ceiling grinding pages). Instant result, adjustable live.

Total jobsite surface, all sections combined.

Surface type

Choose the dominant substrate on site. Throughput varies significantly with substrate hardness.

Each extra operator adds one machine working in parallel on site.

h/day

Actual productive shift time, excluding breaks and setup.

Calculation method

Where does this throughput data come from?

The Sept Tools throughput shown here is taken directly from our published productivity tables by surface (floor, wall, ceiling): Tapir XTT330 on floors, Petit Potam XM165 set with Mygale gantry on walls, Fouine XB165 on a Gazelle trolley or Eland arm on ceilings. These are figures measured in real jobsite conditions, not rounded marketing numbers.

The manual method comparison only appears where an official figure exists: on ceilings, manual pole work caps at 2 to 3 m²/h before physical saturation within 90 minutes. For floors and walls, lacking a verified manual reference, the calculator would rather show nothing than invent an order of magnitude.

Why it matters

Sizing a jobsite before you bid

  • 1Quickly estimate a realistic jobsite duration to size a crew and plan other trades.
  • 2Compare several scenarios (number of operators, hours per day) before locking a schedule.
  • 3Objectively show a client the real time saved by a Sept Tools brushless machine versus a manual method, where the data allows it.

FAQ

Frequently asked questions about jobsite output

How do you calculate jobsite output for grinding, bush hammering or planing?
The base calculation is simple: total surface in m² divided by the machine throughput in m²/h, adjusted for the number of operators working in parallel. Our calculator applies the official Sept Tools throughput measured in real jobsite conditions (the same figures shown on our floor, wall and ceiling grinding pages), returning a jobsite time in hours then in days based on your effective working hours per day.

What is the m²/h throughput of Sept Tools machines on floors, walls and ceilings?
On floors, the Tapir XTT330 handles 19 to 26 m²/h on concrete and reinforced concrete. On walls, the Petit Potam XM165 set with the Mygale gantry handles 10 to 14 m²/h on concrete (the Gazellomur 3-in-1 combo reaches 60 to 90 m²/h on large runs). On ceilings, the Fouine XB165 on a Gazelle trolley or Eland arm handles 12 to 16 m²/h on concrete. These figures drop naturally on renders, adhesives, bituminous coatings and resins.

Why does throughput vary so much depending on the substrate?
The hardness and abrasiveness of the substrate determine how fast the diamond grit can advance without forcing the tool or overheating it. Concrete and reinforced concrete, being harder, require a slower pass than renders, self-levelling compound and adhesives. Bituminous coatings, resins and old carpet glue, often softer but sticky, also require a reduced pace for a clean result.

Does the calculator compare against the manual method?
Yes, but only where an official manual figure exists: on ceilings, where manual pole work caps at 2 to 3 m²/h before physical saturation within 90 minutes. We do not have a sourced and verified manual figure for floors and walls: rather than invent an estimate, the calculator states this honestly and invites you to request a tailored quote.

Are these estimates guaranteed for my jobsite?
No, these are orders of magnitude based on throughput measured in real jobsite conditions, to adjust for access, ceiling height, actual substrate condition and available extraction. For a binding quote, our team reviews your precise constraints with no commitment.

Need a precise quote for your actual jobsite?

Our team reviews your real constraints (access, height, substrate condition, class H extraction) to refine this estimate or arrange an on-site demonstration. No commitment.
