Screed before resin
Le problème
Industrial epoxy resins demand a precise mechanical profile for the bond warranty.
Sept Tools
Tapir plus diamond pad with the right grit to open porosity and ensure adhesion.
Sept Tools
Industrial brushless concrete floor grinding
Professional brushless floor grinders for screed preparation, industrial surfacing and polished concrete finishing, without sparking or overheating.
Concrete floor grinding determines the quality of every coating that follows: epoxy, polyurethane, bonded tile or polished concrete. A poor flatness or untreated high spots will compromise adhesion and shorten the life of the finish. Sept Tools offers a range of French brushless floor grinders that combine torque, reliability and operator comfort. Each machine is engineered to deliver a uniform result on large surfaces without harming the operator over the long term.

Frequently asked questions
Your questions, answered
Which grinder for decorative polished concrete?
The Petit Potam XM165 is our reference for polished concrete: compact, accurate and ideal for the multiple passes needed to reach mirror finish. Pair it with a Turbo7 vacuum for clean operation.
How do I meet silica exposure thresholds?
All our grinders connect directly to our class H vacuums to capture dust at source. The airflow and HEPA filter combination keeps operator exposure compliant with French OEL regulations.
Can I grind a wet floor?
Yes. The IP65 rating allows wet grinding. We recommend a dedicated wet/dry vacuum and a drying procedure between passes for polished concrete work.
What motor power should I aim for?
For daily professional use, we recommend a useful motor power of at least 1600 W, the standard rating across our brushless floor grinding range.
Are your grinders eligible for long-term rental?
Yes. We offer long-term rental contracts including maintenance for businesses looking to spread the investment. Contact us for a tailored quote.
