Why 120 Grit Sandpaper For Drywall Is Necessary
From my experience working with drywall, 120 grit sandpaper hits the perfect balance between smoothing and control. When I’m finishing a drywall surface, I need something abrasive enough to even out joint compound without damaging the paper underneath. Using 120 grit allows me to gently level seams and imperfections without over-sanding, which can happen with coarser grits.
I’ve found that finer grits, like 220, take too long and don’t remove enough material efficiently, while lower grits like 80 or 100 can leave deep scratches that show through paint. The 120 grit gives me enough roughness to quickly smooth surfaces but still leaves a fine enough finish for priming and painting. It’s essentially the go-to grit that helps me achieve a professional-looking drywall finish every time.
My Buying Guides on 120 Grit Sandpaper For Drywall
When I first started working on drywall projects, I quickly realized how important choosing the right sandpaper grit is—especially 120 grit for drywall. It’s that perfect balance between smoothing out imperfections and not damaging the surface. Here’s what I’ve learned to look for when buying 120 grit sandpaper for drywall.
Why 120 Grit is Ideal for Drywall
From my experience, 120 grit sandpaper is just right for drywall because it’s fine enough to smooth joint compound without scratching the drywall paper. It helps create a smooth, even surface ready for priming and painting. Using coarser grits can leave unwanted scratches, while finer grits might take too long to get the job done.
Types of 120 Grit Sandpaper for Drywall
I’ve come across a few types:
- Aluminum Oxide: Durable and reusable, this is my go-to choice for drywall sanding.
- Silicon Carbide: Great for wet sanding if you’re working on damp areas or want less dust.
- Garnet: Natural and softer, but it wears out quickly so I don’t usually pick this for drywall.
Backing Material and Flexibility
I prefer sandpaper with a strong but flexible backing like paper or cloth. It helps me contour to corners and uneven surfaces without tearing easily. For drywall, paper-backed sandpaper is usually sufficient since I’m mostly working on flat surfaces.
Sheet Size and Quantity
Depending on the project size, I choose between pre-cut sheets or rolls. For small repairs, a pack of 9×11 inch sheets works great. For bigger jobs, rolls allow me to cut custom sizes and reduce waste.
Durability and Dust Control Features
One thing I look for is sandpaper that lasts longer so I don’t have to replace it constantly. Some brands offer dust-resistant coatings or perforated sheets that attach to vacuum sanders, which really helps keep my workspace clean and reduces health risks.
Price and Brand Reputation
I’ve found that investing in moderately priced sandpaper from reputable brands saves me time and frustration. Cheap sandpaper tends to clog or tear quickly, costing more in the long run.
Final Tips from My Experience
- Always test a small area first to make sure the grit feels right.
- Pair 120 grit sandpaper with a sanding block or pole sander for even pressure.
- Use a mask and goggles to protect yourself from dust.
Choosing the right 120 grit sandpaper for drywall has made a big difference in the quality of my finishes. I hope these tips help you find the best option for your projects!
