Necessary Preparations

Before you can polish your resin, you will need to do some prepping. This includes gathering supplies, getting a polishing compound, and more. So let’s start!

Supplies Needed

Using a Dremel is a great idea for small and complicated projects. Because controlling where and what you’re polishing is pretty easy with Dremel.

On the other hand, bigger projects will take forever to polish if you use a Dremel. So it is best to use buffing machines for larger resin projects. 

Now we need to gather the needed supplies before we get to polishing the resin. The supplies you need are:

  • Sandpaper 
  • Polishing compound for epoxy resin
  • Microfiber cloth or a towel
  • Power Drill
  • Buffing wheel or polishing tool

Choosing The Polishing Compound

There are multiple different kinds of polishing compounds available in the market. These different compounds cater to different needs.  Because each has different raw materials, different fineness of polishing grain, and is utilized differently in some instances. 

Incredible Solutions Polishing

Incredible Solutions Polishing is highly recommended by us. The compound is made specifically to use with epoxy resin. It is a bit pricey but it is a really good choice.

The Incredible Solutions Polishing is good for removing small surface scratches. But it is also excellent for the final step of sanding and polishing resin projects.  And the compound can be used as frequently as needed.

Homemade Alternative Polishing Compounds

If for whatever reason you cannot get your hands on a marketed polishing compound, you can just make one in your house.

However, homemade alternatives are not the best solution. But it will get the job done.

All you need is toothpaste. Put the toothpaste on the sponge pad of your polishing machine. But be careful about not applying too much pressure. It may burn the resin.

Once all the toothpaste on the sponge pad has been used up, reapply it. Then finally spritz it with water.

Surprisingly, even car wax products can be used. Turtle Wax Polishing Compound is an example. It is efficient at eliminating scratches from resin.

Before You Begin…

Before you begin polishing, you have to make sure that the resin you are working with has a clean and smooth surface. You can use sandpaper for this. To get deeper the scratches on the surface, use sandpaper with a lower grit.

So start with a lower grit when you’re trying to get rid of a bug or smooth out a rough surface.. And then you have to gradually work your way up. 

On the other hand, for surfaces that are reasonably smooth and devoid of flaws, start with higher grit sandpaper. This is because the surface requires less effort.

Using Buffing Machine

The buffing machine is ideal for larger resin projects as it covers a bigger surface area. To use the buffing machine you have to:

Step 1: Preparing The Buff Machine

Start by procuring a power drill or motor. Then attach the buffing wheel or polishing tool to it. Make sure you have enough space to maneuver the buffing wheel properly.

Step 2: Applying The Compound

By Hand

If you are someone that does not have the big tools, you can trust your hand to do the job.

First, get some cotton or linen cloth and apply some toothpaste. Then moisten it up a little with water.

Now you must rub the cloth slowly with circular movements. Apply a little pressure over the resin. It will take some time for the resin surface to have your desired shine.
