PRODUCT FAQ
-
What grit level is this sandpaper, and what type of sanding jobs is it best for?
This sandpaper features an 80-grit rating, which makes it ideal for moderate sanding tasks like smoothing rough surfaces, removing old finishes, or preparing wood and metal for painting or staining. It's coarser than fine-grit papers but finer than extra-coarse options, giving you great versatility for general-purpose work.
-
How many sheets come in each case, and how should I order if I need more?
Each case contains 120 sheets total—that's 6 sheets per pack multiplied by 20 packs per case. If you need additional cases, you can easily reorder using the product number 31576-6, and we're happy to help you set up bulk orders if you'd like.
