Use a floor grinder for smoothing concrete, light coating removal, surface preparation or polishing. For deep reduction or grooving, compare a floor scarifier. Boke Tools lists floor grinder options in Singapore for concrete, wood floor sanding and polishing.

2-minute selection guide
Start with the actual site condition.
Machine size matters, but it should not be the first filter. Two areas of similar size can need different equipment because the substrate, coating, access and target finish are different.
1. Separate concrete from wood
Concrete grinding and wood floor sanding use different machines, tooling and work sequences. Do not group them together only because both jobs happen at floor level.
2. Identify what must come off
Light coatings or residue may suit grinding with the correct tooling. Thick bonded coverings or substantial concrete removal may require stripping or scarifying equipment.
3. Define the next finish
Preparing a keyed surface for a new coating is different from refining a floor toward a polished finish. The tooling sequence matters as much as the machine category.
4. Check access and services
Confirm doorways, edge work, transport route, available power and dust-extraction connection. A wider machine is useful only when it can reach and operate in the work area.
No. Coating type, thickness, bond and the substrate beneath it affect the method. Heavy build-up may need another machine or a different first step.
What is the difference between a grinder and a scarifier?
A grinder is normally used for smoothing, light coating removal, preparation and polishing sequences. A scarifier is the more aggressive choice for deeper removal, grooving or reducing uneven concrete.
Should dust extraction be selected with the grinder?
Yes. Confirm the machine connection, intended industrial vacuum and site dust requirements as one working setup rather than adding dust control after delivery.
Is a wider grinder always better?
No. A larger working path may suit an open area, while access, edges, transport and available power can make a compact machine more practical.
