The best way to make your resin clear after sanding is to polish it with a polishing wheel. There are different types of polishing wheels available, and you can use a rotary tool or Dremel for this as well. A polishing compound is also helpful in removing scratches from the surface of your resin piece, and you can clean it with alcohol afterward.

If you want to make sure that the sanding process has not left any scratches behind, one thing​ you need to do is use the proper sandpaper grits. If you sanded too quickly without using enough pressure on your piece then it’s possible that there might be some scratches leftover which will show up when light hits them at an angle. The trick here is patience!

Don’t worry about the roughness of unfinished resin. Sanding and polishing your pieces will be easy thanks to these handy tools:

  • Micromesh sanding pads are a great way to polish resin. Though they may look like little sponges, they’re actually made out of firm cloth-like material that you can use over and over again. They come in different colors that each represents a different level of thickness—the lower the number, the finer the grit. In fact, I’ve never had to go higher than a 1500 grit sanding pad! These pads can be used on flat surfaces as well as curved ones (like rings). You can find them online or at craft stores like Michaels or Hobby Lobby.
  • Polishing compounds are another great choice for polishing your resin pieces up nice and shiny! These compounds come in sticks that you rub onto a buffing wheel (similar to how you would apply lipstick). The buffing wheels are usually made of flannel, felt, or cotton depending on the brand—again, some brands sell them online while others can only be found at craft stores. You’ll need to attach it to something that spins like an electric drill or Dremel tool. You don’t want your piece moving around too much because it could get damaged by the spinning motion, so try holding it in place with one hand while turning on the power tool with the other hand to avoid mishaps.

How do you buff sanded resin?

Now that you have some sanding techniques at your disposal, it’s time to figure out how to polish resin after sanding. The key is to use low grit sandpaper for initial stages of sanding and higher grits as you move through the process. As soon as you get a smooth texture, you can polish the piece of resin.

The most common ways to polish resin are:

  • wet sanding
  • buffing with a soft cloth
  • buffing with a buffing wheel
  • polishing with heat by using a heat gun or hair dryer

  • Sand the resin with water-based sandpaper. Wet sanding is an effective way to remove imperfections and scratches, as well as to smooth out the surface of the resin. The grits to use are 1500, 2000, 2500, and 3000.
  • Use a polishing compound on your piece’s surface. This will help bring out its natural luster and shine. A good place to apply it is on your buffing wheel if you have one at home (if not, a soft cloth will do).
  • Finish by using a buffing compound that can be applied with either your drill or your buffing wheel/cloth.

Can I use toothpaste to polish resin?

Here are some things to remember when using toothpaste to polish resin:

  • Avoid any types of toothpaste that contain abrasive whitening agents.
  • Avoid gel toothpaste. It’s often too thick and can contain ingredients that can scratch the surface of your project.
  • Use a small amount of regular, non-gel toothpaste and rub it into your project with a soft cloth until you get a uniform layer. Be sure to use smaller circular motions until the paste buffs out. Don’t push too hard – you only need a little pressure to get it to work!
  • Once finished, rinse off all excess residue with water before drying thoroughly so there’s no leftover residue left behind on top of your beautiful newly polished piece!

Can you use car polish on epoxy resin?

Yes, you can use car polish on epoxy. A car polisher will help you achieve a high gloss shine for your finished resin surfaces. You can use a random orbital polisher as long as you don’t go too fast or apply too much pressure.

Choose a polish with fine grit on the label if you have jewelry or other small pieces to polish that requires a delicate finish. You can use coarser or courser grits for larger pieces like tables, especially if there are any imperfections that would benefit from some sanding before applying the car polish.

How do you make resin shiny without polish?

How do you make resin shiny without polish?

  • Use a hardener when mixing your resin. Some hardeners cure the resin in such a way that it is naturally shiny.
  • Heat the surface of your resin piece with a hairdryer or heat gun to make it slightly shiny. You may want to test this on an area of your piece that is not visible as this may cause damage.
  • Try using a high gloss finish. There are several products available that you can use to coat and polish your resin after it has dried. Some like Envirotex High Gloss Finish, have very good reviews from crafters and artists who have used them before. This can be trickier than other methods as you will need to ensure the surface is completely flat and clean before applying the coating, but it has been known to help with scratches too!

Once you’ve sanded your resin, you’ll need to polish it. Your best option is clear nail polish because you can easily find it and it works perfectly. But if you don’t have any, use a gloss medium or sealer instead. If those aren’t available either, try a gloss spray paint.
