Festool Sanding Discs
Festool sanding discs keep your finish clean and your sander cutting properly, whether you are flattening filler, keying paint, or finishing timber.
When you are chasing a proper finish, the disc matters as much as the machine. Festool sandpaper discs are made to stay flat, clear dust, and stick properly to the pad, so you are not burning edges or clogging up halfway through a door set. From Festool Granat discs for hard-wearing all-round sanding to discs that suit Festool Rotex discs style abuse, pick the right grit and diameter and crack on.
What Jobs Are Festool Sanding Discs Used For?
- Flattening filler, nibs, and high spots on refurbs where you need a level surface before paint, paper, or spray finishes go on.
- Sanding timber doors, skirting, and built-ins when you want a clean scratch pattern and less clogging, especially with Festool hook and loop sanding discs that stay put on the pad.
- Keying existing paint and varnish on site joinery so your next coat bites properly without tearing through edges or melting the finish.
- Taking down rough stock fast with Festool Rotex discs type work, where the disc has to handle pressure without shredding or glazing over.
- Keeping dust under control on occupied jobs by pairing the right Festool sanding discs with extraction so you are not sweeping up for an hour after every room.
Choosing the Right Festool Sanding Discs
Pick your disc like you pick your blade: match it to the material and the finish you are aiming for, not just what is cheapest.
1. Disc Diameter: 125mm vs 150mm
If your sander is a 150mm machine, buy Festool 150mm sanding discs and do not try to "make do" with the wrong size, because you will lose edge support and the holes will not line up for extraction. If you run a smaller pad, stick to Festool 125mm discs so the hook and loop lands properly and the disc does not overhang and catch.
2. Abrasive Range: Granat vs Rubin
If you are bouncing between materials like paint, filler, hardwoods, and softwoods, Festool Granat discs are the safe all-rounder because they resist clogging and keep cutting. If you are mainly sanding bare timber for joinery prep, Rubin is the one most lads reach for because it is tuned for wood and gives a clean, controlled scratch ready for finishing.
3. Grit Choice for Site Work
If you are stripping or flattening, start coarse enough to do the job quickly, then step up in sensible jumps so you are not chasing deep scratches at the end. For finishing coats and visible joinery, do not rush the last grit change, because that is where swirls and "picture framing" around edges usually come from.
Who Uses Festool Sanding Discs?
- Joiners and kitchen fitters who need consistent finishes on doors, panels, and worktops without swirl marks showing up under lacquer or paint.
- Decorators and refurb teams keying walls, woodwork, and filled areas, where a disc that clears dust properly saves time and keeps the surface honest.
- Shopfitters and maintenance lads doing quick turnarounds, who keep a spread of grits in the van so they can go from knock-down to finish sanding without changing systems.
Accessories That Help Festool Sanding Discs Perform Properly
A good disc still needs the right support underneath it, especially when you are pushing for a finish on edges and profiles.
1. Replacement sanding pads
If your pad is worn, melted, or the hooks are flattened, even the best Festool sanding discs will slip, chatter, and leave marks. Swap the pad before you waste a stack of discs and wonder why extraction has gone poor.
2. Interface pads
An interface pad is the difference between cutting through corners and getting an even finish on curves, mouldings, and painted edges. Use one when you need a bit of give so the disc follows the shape instead of digging in.
3. Dust extraction hoses and bags
Sanding discs last longer and cut cleaner when the dust is pulled away properly. Keep your extraction set up right so the holes do their job and you are not grinding dust back into the surface.

Festool Sanding Discs FAQs
What is the difference between Festool Granat and Rubin?
Granat is the tough all-rounder for mixed site materials, so it is a solid choice when you are hitting paint, filler, and timber in the same day and you want less clogging. Rubin is aimed at bare wood sanding, so it is the one for joinery prep where you want a clean scratch pattern ready for finishing.
Can I use other brand sanding discs on a Festool sander?
Yes, if the diameter and hole pattern match your pad and the hook and loop backing actually grips, they will work. In reality, if the holes do not line up you lose extraction and the disc clogs fast, and if the backing is poor it can slip or curl at the edge, so it is rarely worth the hassle on finish work.
Do Festool 150mm sanding discs fit every 150mm Festool sander?
They fit the pad size, but you still need to check the hole pattern for extraction and the pad type, especially if you have swapped pads over time. If the holes are off, the sander will still spin, but dust control and cut quality will drop off quickly.
Why are my Festool hook and loop sanding discs not sticking properly?
Nine times out of ten the pad hooks are worn, clogged with dust, or heat damaged from leaning on the machine. Clean the pad face, check it is flat, and if the hooks look shiny or flattened, replace the pad because fresh discs will not stay put on a tired backing.
What is the quickest way to stop Festool sandpaper discs clogging on paint and filler?
Get the extraction working properly and do not sand over damp filler or soft paint, because that is when discs load up instantly. Use a grit that is doing real cutting rather than polishing, and change discs as soon as they glaze, because pushing harder just overheats the surface and makes it worse.
