After you’ve completed the initial sanding, turn off the Dremel and swap out the sanding bit for a finer grit option. Use this to go over the surface again for a smooth and polished appearance. How To Sand Glass by Hand It's often thought that the grit number refers to the number of grit particles per square inch. Not so. Rather, the number scale refers to the number of holes per square inch in the screens that are used when sieving the abrasive grains during the sandpaper's manufacture. For example, in 60-grit sandpaper, the abrasive particles used in the paper were sieved through a screen that had 60 holes per square inch. How Sandpaper Grit Works Move the glass in a circular motion for five minutes over the sandpaper to get the edge smooth. Maintain downward pressure while working to push the edge into the sandpaper. Rotate the piece regularly to ensure uniform sanding. Keep the sandpaper wet throughout the process.

Don’t allow the bit to wear down completely before changing it. Depending on the level of fritz on the edges, you can expect each bit to last 3-5 minutes. That’s usually enough time to finish sanding off the edges but change to new bits if you need to spend more time on the process. The rest of this article will cover all you need to know about sanding and polishing glass. Can You Sand Glass? Sanding Glass To Make It Smaller I use this stuff to sharpen wood chisels and plane irons. I also use It to get a glass-like finish to wood. It works beautifully. In the past I have had problems getting hold of the finer grades and when I have the cost has been prohibitive. This source is both affordable and reliable. Cut out a small circle of sandpaper and use it to work the inner outline of the frosted area. You should also use a small piece of sandpaper on the frosted area. This will help make the appearance uniform. If it starts to wear down, cut out a fresh piece of sandpaper. For narrow areas and fine lines, fold the paper in half and sand using the folded edge. Move to a finer grit and repeat the process until the edge is smooth enough. The grit progression after using a coarse 80-grit is 150-grit, 320-grit, and 400-grit.You need a diamond sand pad of medium to fine grit when sanding glass. You also have to use it wet. This means that your conventional power sander will not work. In many cases, a piece of 320-600 grit sand pad is all you need.

Trizact Performance Sandpaper combines a fast cut and extremely consistent, refined finish for your auto body projects. It features our Trizact structured abrasive - its microscopic three-dimensional mineral structures resemble pyramids. This patterned, precise surface on a lightweight foam removes very fine sand scratches and leaves metal and painted metal surfaces ready for polishing. Cover up areas you don’t want the frosted effect on with a coat of painter’s or masking tape. Use small tape pieces cut into the right shape when covering up tight corners and curved edges. Any piece of glass with the frosted effect will look like your glass window during the winter. The semi-opaque appearance will make any bit of glassware look expensive. You can create the effect with some sandpaper bits and a rotary tool (such as a Dremel or power drill). Here’s what you should do (source: E How):You can sand glass, but instead of standard sandpaper, you’ll need to use a diamond sand pad. The necessary grit type will vary from 80-3000 depending on the project. However, sanding glass is not always the best solution; you may wish to consider cutting the glass or finding a smaller piece. With the Dremel turned on, gently place the side of the bit to the glass surface you’re working on. Work slowly towards the center until you achieve your rounded edge. Attach a sanding bit to the rotatory power tool. Be sure to use a bit that hasn’t been used to get the best results in the past. During the process, you’ll also need to keep the sandpaper wet to avoid getting a lot of glass dust in the air. Additionally, you’ll require a dust mask, safety glasses, and a pair of gloves for personal protection.
