Why 120 Grit Sanding Paper Is Necessary
I find 120 grit sanding paper necessary because it gives me the right balance between removing material and keeping control. It is coarse enough to smooth rough edges, remove light imperfections, and prepare a surface for the next step, but not so aggressive that it causes deep scratches or damage. When I want a surface to feel even and ready for finishing, 120 grit is often my go-to choice.
My experience has shown me that 120 grit works especially well for wood preparation. It helps me level out small marks, clean up after shaping, and create a surface that accepts paint, stain, or primer more evenly. Without this step, I often end up with finishes that look uneven or highlight flaws I could have removed earlier.
I also like using 120 grit because it saves me time later. By starting with a paper that is strong enough to do real work, I can reduce the effort needed in finer sanding stages. For me, it is an important middle step that makes the whole sanding process smoother, cleaner, and more effective.
My Buying Guides on 120 Grit Sanding Paper
What I Look for First
When I buy 120 grit sanding paper, I first think about what I want to use it for. In my experience, 120 grit is a great middle-ground option. It is coarse enough to remove light imperfections, old finish, or rough spots, but fine enough to leave a smoother surface than lower-grit paper. I usually choose it when I’m preparing wood for painting, staining, or a final smoothing step before moving to a finer grit.
Understanding the Grit Level
From my experience, 120 grit is considered medium-coarse. I use it when I need more control than 80 grit but still want decent material removal. It works well for sanding softwood, hardwood, drywall, and even some metal surfaces depending on the project. If I need a surface that is too rough, I go lower; if I need a more polished finish, I move higher.
Choosing the Right Backing Material
I always pay attention to the backing of the sanding paper. Some papers have a paper backing, while others use cloth or film. For general hand sanding, I usually prefer paper-backed sheets because they are affordable and easy to use. If I’m working on a tougher surface or using a power sander, I look for stronger backing that resists tearing and lasts longer.
Considering the Abrasive Type
I’ve found that the abrasive material makes a big difference in performance. Aluminum oxide is one of my go-to choices because it lasts well and works on many surfaces. For more specialized jobs, I may choose silicon carbide or garnet depending on whether I’m sanding wood, metal, or between coats of finish. I always match the abrasive to the job so I get better results and less waste.
Checking Compatibility with My Tools
Before I buy, I make sure the sanding paper fits the tool I plan to use. Some sheets are made for hand sanding, while others are sized for orbital sanders, detail sanders, or sanding blocks. I’ve learned that buying the wrong size can be frustrating, so I always double-check the dimensions and hole pattern if I’m using a machine sander.
Durability and Longevity
I prefer sanding paper that holds up well and doesn’t clog too quickly. In my experience, better-quality 120 grit paper saves time because I don’t have to replace it as often. If I’m sanding paint, wood, or filler, I look for anti-clogging features or coated abrasives that stay effective longer.
Dry or Wet Sanding Use
Depending on my project, I decide whether I need dry or wet sanding paper. For most woodworking tasks, I use dry sanding paper. If I’m working on automotive finishes or very smooth surfaces, I may choose wet/dry paper. I always check the packaging so I know whether the paper is suitable for water use.
Value for Money
I don’t always go for the cheapest option. I’ve found that very low-cost sanding paper can wear out fast, which ends up costing more in the long run. Instead, I look for a balance between price and performance. If a pack gives me good durability and consistent sanding, I consider it a better value.
My Final Buying Tip
If I’m choosing 120 grit sanding paper, I focus on the surface I’m working on, the tool I’m using, and how long I need the paper to last. For me, the best option is the one that sands smoothly, lasts reasonably well, and matches the project without causing unnecessary scratches or wasted effort.
Final Thoughts
I find 120 grit sanding paper to be one of the most versatile options for everyday sanding tasks. It gives me a good balance between removing material efficiently and leaving a surface that’s smooth enough for the next step. My takeaway is that it’s a reliable middle-ground grit for preparing wood, refining edges, and getting projects ready for finishing.
