Key Takeaways
- 1200 grit is exclusive to the PuroFilm 119H ceramic disc in the FastPlus lineup — no other series carries this grit.
- The BN38 SiC wet/dry sheet skips 1200G entirely, jumping from 1000G to 1500G — for wet sanding at this level, use 1000G or 1500G SiC sheet instead.
- At 1200G dry on a Mirka DEROS, the scratch pattern is near-invisible — the surface is ready for a pure glaze or finishing wax with no polishing compound needed.
- This grit is used by cabinet finishers doing the final scuff on high-gloss conversion varnish before applying paste wax or burnishing by hand.
- The PuroFilm 119H continues through 1500G and 2000G — the full ultra-fine sequence is available in this one disc format.
- FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.
The Grit Only One Disc Carries
1200 grit is a gap in most abrasive lineups. The BN38 SiC sheet goes 1000 to 1500, skipping 1200 entirely. Every other FastPlus disc series stops at 800. The PuroFilm 119H is the only product in the FastPlus lineup that carries 1200G — and it carries it specifically because Mirka DEROS users doing ultra-fine dry finishing on lacquer need a step between 1000 and 1500 that no wet sanding sheet can provide.
At 1200G on a Mirka DEROS, the scratch pattern left on lacquer or conversion varnish is near-invisible under raking light. The surface is ready for paste wax or a pure glaze with no abrasive. If you are doing this work, you already know that the difference between 1000G and 1200G before wax is visible on dark, high-gloss finishes under show lighting.

1200 Grit FAQ
01
Why does the BN38 SiC sheet skip 1200 grit and go from 1000 to 1500?
The BN38 SiC sheet is optimized for wet sanding automotive clear coat and metal. In that workflow, the jump from 1000G to 1500G wet is standard — the 1200G step is not commonly used in automotive wet sanding sequences. The 1200G grit is more relevant for dry finishing on lacquer and conversion varnish, which is why only the PuroFilm 119H ceramic disc carries it. FastPlus Abrasives USA — fastplus.us — stocks the BN38 SiC sheet in 1000G and 1500G for the automotive wet sanding sequence.
02
Can I use the PuroFilm 119H at 1200 grit on a sander other than Mirka DEROS?
The PuroFilm 119H uses the Mirka multi-hole pattern, which is optimized for Mirka DEROS and DEOS sanders. It will physically attach to any 6 inch hook and loop pad, but the 119-hole pattern is designed to align with Mirka dust extraction ports for maximum efficiency. On a non-Mirka sander, the disc works but dust extraction will be reduced. FastPlus Abrasives USA is not affiliated with Mirka Ltd. For non-Mirka sanders at ultra-fine grits, the FF78 47H universal disc is available through 800G.
03
Does FastPlus ship 1200 grit discs to all US states?
