Key Takeaways
  • 180 grit has the widest product coverage in the FastPlus lineup — 10 products across discs, rolls, strips, and wet/dry sheets.
  • The FF78 47H Universal disc does not have a 180G variant — if you need 180G on a universal 6-inch pad, use the F65 49H or PuroFilm 119H instead.
  • 180 grit is the standard final prep grit before most oil-based and water-based topcoats on hardwood — it removes 150 grit scratches and leaves a surface the finish can grip without telegraphing orbital marks.
  • The BN38 SiC wet/dry sheet in 180 grit is the right tool for wet sanding automotive primer and clear coat — silicon carbide cuts cleanly in water without loading.
  • PuroFilm strips (2.75" x 16.5" and 2.75" x 7.8") bring 180G to hand block and detail sanding where a random orbital cannot reach.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

The Most Complete Grit in the Lineup — and One Surprise Gap

180 grit is where the FastPlus product range is deepest. Ten products carry a 180G variant — more than any other grit — covering every format from 5-inch discs to 6-inch discs, PSA and hook-and-loop rolls, sanding strips in two lengths, and a silicon carbide wet/dry sheet. If you need 180 grit, there is almost certainly a FastPlus product in the format your job requires.

The one gap worth knowing before you order: the FF78 Blue Ceramic 6-inch 47-hole Universal disc — the most flexible 6-inch disc in the lineup — does not have a 180G variant. Its grit range jumps from 150 directly to 220. If you have been using the FF78 at 150 and need to continue to 180 on the same sander, switch to the F65 49H or PuroFilm 119H for the 180G pass.

180 Grit FAQ

01 Why does the FF78 47H not have a 180 grit variant?
The FF78 Blue Ceramic 6-inch 47-hole disc is available in 40, 80, 150, 220, 240, 320, 400, 500, 600, and 800 grit — but not 180. This is a product line decision by the manufacturer. If you need 180 grit on a 6-inch sander, use the F65 49H (Festool-compatible) or the PuroFilm 119H (Mirka-optimized). Both carry 180G and are ceramic film. FastPlus Abrasives USA — fastplus.us — notes this gap clearly so you can plan your grit sequence before ordering.
02 Is 180 grit fine enough to apply finish directly after?
For most oil-based finishes on hardwood, yes — 180 grit is the standard final prep grit before polyurethane, oil, or varnish. For water-based finishes, 180 is acceptable but some finishers prefer 150 for better mechanical adhesion. For lacquer or conversion varnish in a production environment, 180 is typically the stopping point before the first coat. Do not go finer than 180 before oil-based finish — the surface becomes too smooth for the finish to grip properly.
03 What is the BN38 SiC sheet used for at 180 grit?
The BN38 silicon carbide wet/dry sheet in 180 grit is designed for wet sanding applications where water is used as a lubricant. Common uses: scuffing automotive primer before guide coat, wet sanding between clear coat layers, and smoothing metal before primer. Silicon carbide cuts cleanly in water without loading, and the waterproof backing holds up through extended wet sanding sessions. It is not designed for dry orbital sanding — use the ceramic or aluminum oxide discs for that.
04 Should I use 180 grit between finish coats?
180 grit is on the coarser end for between-coat sanding. It works for knocking down raised grain after the first water-based coat on open-grain wood, or for scuffing a fully cured oil-based coat before recoating. For finer between-coat work — especially on lacquer, conversion varnish, or after the second coat — use 220 or 320 grit. The PuroFilm strips in 180G are useful for between-coat hand sanding on flat panels where you want more control than a random orbital provides.
05 What is the difference between the PuroFilm strip 16.5" and 7.8" at 180 grit?
Both are the same ceramic film abrasive (FT77 series) with the same 180G grain — the difference is length. The 16.5-inch strip fits longer longboard sanding blocks used for auto body panel work and wide furniture surfaces. The 7.8-inch strip fits shorter hand blocks for detail sanding, cabinet interiors, and areas where a longer strip would be awkward. Both use hook and loop (Velcro) attachment and have 8 or 14 holes for dust extraction. FastPlus Abrasives USA — fastplus.us — carries both lengths in 180G.
06 Does FastPlus ship 180 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.
