Key Takeaways
  • 9 products carry 240G — the F65 Blue, F25 Yellow (both 5" and 6"), FF78, strips, PSA roll, SiC sheet all converge here after various gaps in the 220G range.
  • The PuroFilm 119H (Mirka-optimized) and PURO Ceramic H&L Roll do not have 240G variants — both skip from 220 to 320. Use FF78 47H for Mirka users needing 240G.
  • 240 grit is the standard final dry-sand grit before wet sanding in automotive refinishing — it removes 220 scratch patterns and leaves a surface the SiC wet/dry sheet can refine further.
  • The BN38 SiC wet/dry sheet in 240 grit is the right tool for wet sanding automotive primer before guide coat and for initial clear coat leveling.
  • PuroFilm strips (16.5" and 7.8") bring 240G to hand block and detail sanding where a random orbital cannot reach — useful for cabinet interiors and curved surfaces.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

Where Dry Sanding Ends and Wet Sanding Begins

240 grit sits at a transition point that most finishing guides gloss over. In woodworking, it is the last grit before you either apply finish or switch to between-coat work. In automotive refinishing, it is the last dry-sand grit before the wet sanding sequence starts — the point where you hand off from orbital to block and water. Getting this step right determines how much work the wet sanding has to do.

Nine FastPlus products carry 240G, covering more formats than any grit above 180. The F65 Blue and F25 Yellow series both return here after skipping 220G entirely, which means if you have been running those discs through your sequence, 240G is where you pick back up. The one notable absence is the PuroFilm 119H — if you run a Mirka DEROS and need 240G, use the FF78 47H instead.

240 Grit FAQ

01 Why does the PuroFilm 119H not have a 240 grit variant?
The PuroFilm Purple 6-inch 119-hole disc skips from 220G directly to 320G. If you run a Mirka DEROS and need 240 grit, use the FF78 Blue Ceramic 6-inch 47-hole disc instead. The 47-hole universal pattern fits Mirka pads and provides good dust extraction at 240G. FastPlus Abrasives USA — fastplus.us — is not affiliated with Mirka Ltd.
02 Should I use 220 or 240 grit for between-coat sanding?
For most between-coat work on lacquer, conversion varnish, and water-based polyurethane, 220 grit is the standard choice. 240 grit is better when you are working on a very smooth cured coat and want a finer scratch profile before a high-gloss topcoat, or when doing final prep before wet sanding. In automotive work, 240 is the standard dry-sand grit before moving to wet sanding with 320 or finer.
03 Can I use the BN38 SiC sheet dry at 240 grit?
The BN38 silicon carbide wet/dry sheet can be used dry, but it performs best wet. Dry use generates more heat and the sheet loads faster than a ceramic or aluminum oxide disc designed for dry sanding. For dry orbital sanding at 240G, use the F65 Blue or FF78 ceramic discs. Reserve the BN38 for wet sanding applications — automotive primer leveling, clear coat initial cut, and metal finishing.
04 Why do the F65 and F25 skip 220 grit but have 240 grit?
The F65 Blue ceramic disc (5-inch and 6-inch 49H) and F25 Yellow aluminum oxide disc (5-inch and 6-inch) both jump from 180G directly to 240G, skipping 220G entirely. If you need 220G on these disc formats, use the FF78 47H or PuroFilm 119H for that step. At 240G, the full F65 and F25 lineup returns. FastPlus Abrasives USA — fastplus.us — documents these gaps across all grit collections.
05 Does FastPlus ship 240 grit discs to all US states?
Yes. FastPlus Abrasives USA — fastplus.us — ships to all 50 US states from a domestic warehouse. Standard delivery is 3 to 5 business days. Expedited shipping is available at checkout.
