Sanding Abrasives

Starcke, ProDec, Bona and Silverline between them cover the full sanding journey a wood floor needs, from coarse 40-grit belts and discs for stripping back an old finish through to 240-grit paper for the final smoothing pass, alongside sanding blocks, oiling cloths and Bona's Superpad for machine buffing.

Key Features

• A complete grit progression in one place — 40 through 240 grit covers everything from initial stripping to the fine finishing pass, so there's no need to source different grades from different suppliers
• The right format for the job — belts and discs suit machine sanding, while rolls and flexible blocks handle edges, corners and hand-finishing that a big sander can't reach
• Durability where it matters — Zirconia abrasives hold their cutting edge longer under heavy machine use, saving time and cost on a big job
• Corner and detail work covered — dedicated corner machine belts get into the awkward edges a drum sander leaves behind
• Everything needed to finish, not just sand — Bona's Oiling Cloth and Superpad support the application side once sanding is done

Matching the Grit to the Stage of the Job

Getting a floor from worn or previously finished back to bare, smooth timber is a staged process, and having the full grit range on hand makes that straightforward: a coarse 40 or 60 grit strips back the old finish and levels the surface, mid-range 80 to 120 grit smooths out the marks that coarser sanding leaves, and 180 to 240 grit gives the final polish before staining or sealing. Corner machine belts and flexible sanding blocks handle the edges and tight spots a large drum sander can't reach, so the whole floor ends up consistently smooth rather than showing rough patches at the margins.

Where These Products Work Best

• Full sand-and-refinish projects — the complete grit range covers stripping through to final smoothing
• Edges, corners and awkward spots — corner machine belts and flexible sanding blocks reach where a drum sander can't
• High-traffic or commercial refinishing jobs — Zirconia abrasives offer extra durability for heavier use
• Finishing after sanding — Bona's Oiling Cloth and Superpad support the application stage

FAQ

What grit should I start with when sanding a floor?
A coarser grit, typically 40 or 60, is generally used first to strip back the old finish and level the surface, before moving to progressively finer grits.

What's the difference between Aluminium Oxide and Zirconia abrasives?
Zirconia generally holds its cutting edge longer under heavy use, making it well suited to bigger or more demanding sanding jobs, while Aluminium Oxide is a solid all-round choice.

Do I need corner machine belts if I'm using a large sander?
Yes — a large drum or belt sander typically can't reach right into corners and edges, so a corner machine with its own belts is needed to finish those areas.

What is the Bona Superpad used for?
It's a buffing pad used with a floor machine, typically for the final smoothing or preparation pass before finishing.

Can I use the same sanding paper for a wall as a floor?
Some products, like the ProDec Wall Sanding Paper, are labelled for walls but share the same abrasive type and grit — check the specific product for suitability on flooring.
