Choosing the best epoxy polishing compound

There are many different polishing compounds available, each with a distinct fineness of polishing grain, each utilized differently in some instances, and each produced for various materials. Here are some options you can choose from:

Incredible Solutions' Polishing Set comes highly recommended as they have a lot of expertise with epoxy resin. When combined with the appropriate cleaning, their polishing compound produces the greatest results.

TOPFINISH 2 is a fine-finish polishing compound designed specifically for tough plastics like epoxy resin. The fine nano-particle formulation may be used to generate greater levels of gloss on polished epoxy resin surfaces, as well as restore shine to damaged or heavily worn surfaces.

The Liquid Smooth polishing product from Stone Coat Countertops will take your shine to the next level. Apply the compound on the buffing pad and the epoxy, then buff!

Household alternatives for resin polishing compounds

One trick to polishing the epoxy is to use toothpaste on the sponge pad of your polishing machine. Be careful not to put too much pressure on the epoxy or it may burn. While spinning, gently contact the pad to the epoxy. When you've used up all of your toothpaste, reapply it and spritz it with water.

You may also use a polishing product for cars. Turtle Wax Polishing Compound, for example, is advertised as being efficient at eliminating scratches from resin.

What you need to know about the polishing technique

When polishing, you want to make sure you have a smooth, clean surface to work with. Working your way through various grits of sandpaper can help you achieve this: the lower the grit, the deeper the scratches on the surface will be. 

So, whether you're attempting to get rid of a bug or smooth out a rough surface, start with a lower grit and gradually work your way up until the surface is smooth.

If your surface is reasonably smooth and devoid of flaws, you'll probably start with higher grit sandpaper because the surface requires less effort.

Sanding between coats of epoxy

You may notice bubbles, hair, or dust that landed on your piece when it was wet and dried into your resin. However, you can attempt to correct any surface flaw even after the first application. Sanding epoxy resin between applications will remove the flaws and also add sharpness to the transition between the layers.

Wipe away any sanding debris before pouring a second coat of well-measured, well-mixed Roxy Epoxy resin over the top, then cover with a dust cover to ensure you don't repeat the same mistakes. You are now ready to go! 

Why is my resin dull after sanding?

A hazy epoxy can be caused by a variety of reasons, including humidity, mold texture, and resin temperature. To avoid cloudy epoxy, avoid working in a humid environment and make sure the mold is clean and dry before pouring.

How to get epoxy clear and shiny after sanding

How to get epoxy clear and shiny after sanding

Cured epoxy resin does not necessarily have a shiny, transparent surface. It's possible that the original finish will appear rough or dull in some cases. For a better appearance, you'll need a little to heavy polishing to make the finish look shiny and clear.

Polish a bigger chunk of resin with a buffing wheel (or any other polishing instrument). The buffing wheel should be attached to a power drill to make the procedure easier. Apply it evenly to the resin until it is glossy and smooth, and rub the surface with a microfiber cloth.

When using a polishing compound, remember to work in tiny parts to create a uniform shine throughout your job. 

Manual vs. machine polishing - can you use a Dremel to polish resin?

When working on a smaller, more complicated task such as jewelry, a stationary disc sander and buffing wheel may be more convenient than sanding and polishing by hand. Using this sort of equipment helps you to handle tiny details with greater accuracy and control. Using a Dremel is great for little things and controlling where and what you're polishing.

For large tasks, a buffing machine is suitable. As previously said, a Dremel works great for complexities and smaller jobs that may then be completed by hand. Using a Dremel to clean a whole table would take a long time and could still require touch-ups.

Wrap up

There's a lot that goes into making your product look like it's made of glass. Pour your epoxy and allow it to cure completely. After you've gone over your project and demolded the casting, you can see any flaws that need to be addressed. Remember to be patient and take things one step at a time. It will all be worth it in the end!
