Sandpaper explained

Do you think all sandpaper is the same? Well, it's not. Let's get after it. Let's start with grit. The grit number tells you how aggressive the sandpaper is. The lower the number, the larger the abrasive particles. The higher the number, the smaller the abrasive particles. The way that they find grit is how many abrasive particles are in 1 square inch. 40, 60, 80 are going to be for your heavy sanding. Your 100, your 120, your 150, and your 220 are your general sanding. And anything 300 and above is your finish sanding. Not all sandpaper is made from the same material, either. This is ceramic sandpaper. It's going to last the longest, and it's great for heavy sanding. Think of hardwood floors and metal. Aluminum oxide sandpaper is your all-around general use sandpaper. Maybe woodworking projects, softer metals, things like that. Silicon carbide sandpaper can be used either wet or dry. But a lot of times it's used wet sanding on automotive work. Woodwork, this would be used in your lacquers, and not just on your raw wood. Can also be used on plastic and fiberglass. Sandpaper also comes in many different forms, and is designed for many different tools. Sheets are great for hand sanding, or used with a block. Hook and loop discs are made for random orbital sanders. Drywall sanding screens like this one have little holes in them that reduce clogging from drywall dust. My oscillating multi-tool uses triangular sanding pad to get into tight corners. This 9-in hook and loop pad is for my drywall sander, and it makes quick work out of walls and ceilings. If you're sanding drywall, and you don't want any dust, you can go ahead and use a sanding sponge. And always remember, start with the coarsest grit that you need, and work your way all the way up to the finest grit that you need. Anyways, I got some sanding to do. I'll catch you guys later. Peace.
