This article will expound on how to polish epoxy resin and more so for epoxy-based materials.

Materials needed

Have Polishing materials ready before the onset of the exercise. Below are the basic ones that will give a shiny look after polishing has been done.

  • Sand Paper- This can be of 120,180,220,400,600,800,1000,1500 and 2000  grit
  • The sanding block
  • Water
  • Polishing compound
  • Scratch remover compound
  • Scratch-free polishing cloth
  • Buffing compounds
  • Wax products
  • Clean working surface

Now that the materials are ready, it’s time to start Polishing the Epoxy Resin to look as new. Below are the researched and well-known steps to carry out this procedure;

Step 1 – Sanding The Epoxy Resin

When sanding the epoxy resin, the first thing that one needs to do is cleaning the surface.  Use a clean piece of cloth with soapy water to remove any dirt or mold before the sanding process starts.

Some of the molds may be hard to the extent that removing them using the damp cloth may not be possible. In such a case, it’s recommended to use water and special sandpaper to scrub the mold. This process is called wet sanding, and it’s done at the initial stage of polishing.

While wet sanding, use 400 grit sandpaper and ensure that any visible scratches are removed.  Confirm that the entire surface is sanded thoroughly before proceeding further.  The main advantage of wet sanding compared to dry sanding is that wet sanding does not exaggerate the type of dust emitted when using the dry sanding method and, therefore, is more preferred.

Caution: Do not work without a respirator. Wearing one will keep one away from inhaling airborne particles that might be a menace to one’s health.

Step 2 – Repeat The Sanding Exercise by Use of Finer Grit Sandpaper

As mentioned in the first step, we used 400 grit sandpaper. In this step, use 600 grit, then 800 grit, 1000 grit, and lastly, use the 1500 grit sandpaper. The higher the sandpaper grit that one is using during the process, the soother finish one will be expected to get.

Take note of the surface when sanding and confirm that every grit has done its part before proceeding to the next grit. By the time you get to the 1500 grit sandpaper, the piece is expected to be very smooth to pave the way for the following process.

Step 3 – Removing any left-over Dust or Grit

Once comfortable with the sanding process, dry off the epoxy resin piece using a towel. Confirm that no single particle is sighted, neither any dust before the polishing compound is applied. 

Take a quick test by sanding again with a 1500 grit sandpaper and ensure that no resin is left.  Wet the resin with small amounts of water. Scratches become more visible, and if you missed any of them, you would be able to clear them completely.

Step 4 – Apply The Polishing Compound

To get a fine finish in your resin, apply the polishing compound gently and spread it in a uniform manner across the resins’ surface.  When purchasing one, look for the fine scratch remover compound. It gives better results, and it’s available in most of the stores.

Among the best polishing compounds include the Turtle wax polishing compound. After the polishing exercise, give it another break; close to five minutes and buff it once more with a clean piece of cloth.

In case you have a larger piece of resin that might take time to buff using a piece of cloth, use a buffing wheel or a polishing tool. Ensure that the buffing wheel is appropriately attached to a power drill to be able to work perfectly.

As you carry out the procedure, see to it that the wheel is continuously moving in a circular motion.

Step 5 – Final Polishing

This is the last stage where one is expected to obtain a shiny and smooth surface. Polish the resin until the surface appears smooth to your desired requirements, and the whole process will be complete.

How can one Make Resin Shiny after Sanding?

Using a colorless polishing compound and polishing the surface until you obtain the desired shiny results is the only way to get a crystal clear shine. To add to this, moisten it with some little water and, as mentioned before, rub on a circular movement. Within a short while, you will obtain the desired results.
