Using Sandpaper

Sandpapers are handy and highly effective when it comes to smooth glass edges. You can choose a grit number depending on the sanding demand. And it’s better to use wet-dry paper; also, you will need some protective gear to save yourself from the glass dust.

  • Step one: At first, take lower grit sandpaper from 80 to 100 and dip it into the water to thoroughly wet it. The more wet the paper is, the less will be the glass dust. So, make sure it’s very wet before you begin sanding.
  • Step two: Once your sandpaper is ready, now you can begin sanding. For a finishing container, cup, or glass edges, you need to set the cut edge onto the paper with your dominant hand. And hold the paper steady with your other hand.

Now, with gentle downward pressure, rotate the glass in annular motion for every 2-3 rounds. This will ensure uniform sanding, and hence even finishing. Within about 5 minutes, the edges should be adequately smooth.

  • Step three: As the edges are smoothed well, now take the glass and now sand the outer and inner corners with a hand. Make sure to dip the paper into the water again before this step. And continue sanding until the desired polishing is achieved but make sure you keep the paper wet by frequently dipping into the water.
  • Step four: This step is all about perfection. Repeat sanding the edges with higher grits, first with 150, then 220-320, and finally with 400 grits. Once the edges are even and smooth, you can use 1000 or 2000 grit papers to shoot for perfection.

Using Silicon Carbide Powder

To polish glass with silicon carbide powder, you need a float glass, foam, and spray bottle. And follow the below steps to smooth of glass edges.

  • Step one: First, take the float glass or any piece of window or mirror glass and place it over foam or paper so that it keeps still while sanding. Now pour a small amount of water over the glass piece and just enough powder to make a puddle. You can hand stir the powder and water to form a mixture.
  • Step two: Now place the glass edges over the puddle and hold tight with your hand. Then rotate the glass in annular motion for 30-60 seconds with gentle downward pressure. Repeat encircling for some time and check if the edges are smoothened.
  • Step three: As you are done smoothing the edges, now wipe the glass with a cloth or towel to remove the silicon carbide and water mixture from the glass surface. Then use moist sandpaper to sand inside and outside corners to achieve even finishing.

FAQs about Sandpaper for Smoothing Glass

What grit sandpaper is best for glass?

Ans. Choosing the grit number depends on how finished you want the surface and how delicate the object you are working on is. Most often, 80 grit sandpapers are used for the primary sanding of glass planes. After that, increasingly higher grit numbers are used to achieve more even, perfect, and glossy finishing.

Does sandpaper scratch glass?

Ans. If you use lower grit papers like 35-40 over the glass, it might cause scratches. Higher grade ones remove any uneven blurs or blemishes from glass and smoothen it. After sanding with an 80-100 grade paper, it is again sanded with higher grade ones to get it perfectly polished without scratches.

Is sanding glass dangerous?

Ans. Sanding over glass produces minute glass dust. These tiny particles irritate the eyes and lungs if breathed in. Also, you can cut your hand with the specks of dust. So, putting on protective gear like musk, gloves, and goggles is necessary while glass sanding.

How can I remove sand scratches from the glass?

Ans. Other than using sandpaper or silicon carbide powder on glass objects, if you have any tiny scratches on glass windows or mirrors, you can use toothpaste or clear nail polish to diminish flaws, fill in grooves, and minimize scratch appearances.
