How do you make resin clear again?

If you’ve ever bothered to look up a resin tutorial, the first thing they’ll tell you is that it can be used for making jewelry. This is true—I discovered that myself in middle school when I made one of those classic beaded necklaces with a layer of opaque, yellowing resin over the top.

I thought it was cool at the time, but now I prefer to think of my artistic endeavors as more advanced than crafting with beads and glue. But then again, if you’re like me and you love to create things but are not naturally skilled at any given art form (I make paper boats like nobody’s business), then maybe this isn’t quite your ideal project either.

I’d recommend that if you’re looking to mess around with resin for funsies and don’t have much experience doing so, start out by putting small objects in it.

Look up how-to videos on YouTube—there are literally thousands of them, plus most people who demonstrate crafts seem very friendly because they’re excited about their work (which is something we should all strive for).

How do you get resin clear again?

  • Make resin clear again by adding more resin. You can easily make clear resin by adding a little bit of fresh, new, unset resin to your cloudy and thickened epoxy resin. You don’t need a lot to fix the problem and return your epoxy back to its original state.
  • Add a few drops at a time and mix it in thoroughly. Continue doing this until all the clumps are gone and you have completely mixed the two resins together. Your resin will be smooth, shiny, and clear again!

How do you fix cloudy epoxy?

To clear up resin that has become cloudy, you’ll need to follow these steps:

  • Sand the entire surface with fine-grit sandpaper.
  • Clean the resin with alcohol if it’s still clumpy or goopy in some spots. Repeat this step if necessary.
  • Apply a fresh coat of resin to the entire surface, and repeat this step as many times as it takes to get a smooth and clear finish on the resin you’re working on. Always wait 24 hours between coats!

How do you make resin smooth and clear?

To make resin clear and smooth, you can:

  • Sand in between layers. You’ll want to start sanding with 400 grit wet/dry sandpaper or a sanding sponge and then move on to 600 grit wet/dry sandpaper.
  • Be patient. This step is going to take time, so be prepared for that. You may need to spend several hours at it before your resin becomes clear and smooth again.
  • Use a heat gun. If you have one of these, try using it after you’ve done the above two steps to get your resin really smooth. But be careful—you don’t want to melt the resin!

If none of the above work for you, there are several alternatives:

  • Consider using a UV resin next time instead of regular epoxy resin. UV resins harden when exposed to sunlight or other UV rays and don’t require as much patience during the curing process as regular epoxy resins do (though they might not be right for all projects). They also tend to set more consistently than regular resins do, which means they’re less likely to leave bubbles in your piece—and that can make them easier on which ones need help.)

Can you polish resin with toothpaste?

No. Toothpaste is too abrasive and will scratch your resin. Even the gentlest non-abrasive toothpaste is still not ideal for polishing your resin piece.

You’re better off using a microfiber cloth or a polishing compound designed for use with epoxy resin to get that high gloss shine back.

How do you make resin shiny without sanding?

You can use a heat gun to make the resin shiny without sanding it. First, apply some heat to the dull area, then rub the resin vigorously with a soft cloth.

The heat will bring back the shine and plasticity to your resin. Alternatively, you can use a polishing compound, polishing buffer, or rubbing compound.

You’ll also need a cloth and soft sponge for this method. Apply enough of the polish over your resin until it’s fully covered with it.

Then start buffing away in small circles until you see an even shine all over your resin piece.

This should work for smaller molds and pieces of jewelry but if you have bigger pieces then you may have to try different methods like using a tumbler or Dremel tool to polish your resin without having to sand it down first.

How do you make resin shiny after sanding?

To make resin shiny after sanding, you should use a buffer and polishing compound.

You can also use a Dremel or heat gun (hair dryer) to make resin clear again.

Can you fix cloudy resin?

They are among the most common resin parts, and they can be tricky to deal with. The resin we use on MA builds starts out clear and then becomes cloudy because it has a chemical reaction with air. This is the first thing we need to fix in order to get our final products looking as good as possible when assembled.

Step 1: If the problem is very severe, you can speed up the cure using a heat gun. Heat the piece until it boils (almost simultaneously). Then immediately mix in a small amount of base-clear resin to stop coloration from happening.

Step 2: Mix all of your ingredients together, but don’t spread them on yet. Put your piece undercover or cover it lightly with damp paper towels for a few hours so that bubbles don’t form (they will when you remove it from the sink).

Mix again after this period (for best results, do this 2-3 times) until you get something that looks like lumpy icing or putty mixed with water (it should hold its shape well enough right now).

You want these first two steps to be fast so that light can pass through your mixture quickly without picking up visible imperfections during drying times.

Why has my resin dried cloudy?

Cloudiness in resin is not caused by any impurities in the resin, hardener, or other tints you may have added. If the resin has yellowed or is otherwise discolored, this usually indicates that it was exposed to sunlight or artificial light for too long during the curing process.

It can also happen if the temperature was too high during this stage. The most likely cause of cloudy resin is that it simply hasn’t been completely cured yet. You can tell if your resin has fully cured by checking its color; if it’s still relatively white and opaque, then it’s just not finished yet!

A common reason for cloudiness is incorrect mixing ratios, particularly when working with large quantities of resin such as those used by professionals to make countertops or work with epoxy on a regular basis.


So there you have it! You now know how to sand and polish your resin art. By following these steps, you’ll be able to improve the look of your resin artworks and make them into high-quality pieces that will impress people for years to come.

You can also use a resin polisher to get the job done, which is much quicker than sanding by hand. However, this method is more expensive and can be quite noisy—it may not be ideal if you live in an apartment or you have young children who need quiet when they’re sleeping.

If traditional methods work well for you and your budget allows it though, then using one might save significant amounts of time (and wrist pain!).
