120-grit Rhynalox Plus sheets for smoothing
120 grit is the middle step. After the coarse pass has flattened things out, this is the sheet that smooths primer and gets a surface ready for paint or topcoat. These are Indasa Rhynalox Plus, an aluminum oxide grit on a paper backing made for dry sanding.
The coating resists clogging, so it keeps cutting clean instead of glazing over and dragging. Use it on old paint, fillers, primers, and wood coatings.
Frequently asked questions
What is 120 grit sandpaper used for?
120 grit is the middle step for smoothing. After a coarse pass has flattened things out, this is the sheet that smooths primer and gets a surface ready for paint or topcoat. These 120-grit sheets work on old paint, fillers, primers, and wood coatings.
Is 120 grit rougher than 80 grit?
No. 120 grit is finer than 80 grit. 80 is the coarse, rough-work end, and 120 is the middle step you move up to after the coarse pass to smooth primer and prep the surface for paint or topcoat.
Will 120 grit remove paint?
120 grit can cut old paint, but it is the middle smoothing step rather than the heavy stripper. For knocking down old paint fast, start coarser with 80 grit, then step up to 120 grit to smooth before paint or topcoat. These sheets are made to sand old paint, fillers, primers, and wood coatings.
