How do you get the perfect finish on epoxy resin?

Epoxy resin is a useful compound that can be used to seal and finish surfaces, or create a beautiful piece of jewelry or art.

Epoxy resins are made up of two parts: an epoxide resin and a polyamine hardener, which must be combined in precise quantities to cure properly.

Once the right amount of hardener is added, the mixture can begin to cure after only around half an hour.

Epoxy resin has many uses. It’s most commonly used as an adhesive for woodwork, as it forms strong bonds with other materials and is easy to mix and apply.

It’s also used for filling gaps between different types of flooring and for creating coatings on worktops because it has high resistance to water, chemicals, and heat damage.

However, epoxy resin can also be used to create jewelry pieces like bangles by mixing in color pigments or even crushed glass!

What’s great about using epoxy resin is that it cures fast – so you can get your hobby project finished quickly! It’s also really easy to mix together using a 1:1 ratio of epoxide resin to polyamine hardener by volume (100g: 100g).

Epoxies are available in both clear coats (ideal if you’re making something decorative) or opaque colors depending on your preferences!

How do you make a perfect epoxy finish?

We have spent years making mistakes and learning how to achieve the perfect epoxy resin finish on all kinds of surfaces. Now you can learn from our trial-and-error process, saving yourself time and money.

This guide will teach you how to make resin smooth, shiny, and clear. Your finished products will look like glass or plastic! Our formulas are so good that no one will even guess it was made with epoxy resin.

How do I get a smooth resin finish?

If your resin has gone wrong, it may be because you’ve used the wrong tools. This is not usually an issue for most people as the tools needed are inexpensive and easily obtainable from Amazon.

If you have tried to use a brush or paint pad and have had a rough finish then don’t worry, there are some simple fixes.

Start by sanding with 80 grit sandpaper, then apply another coat of resin using a foam roller. The roller will ensure that your resin is level and spread evenly.

The easiest way to avoid bubbles is to use a heat gun or blow torch (or hair dryer if you don’t have either of these) when applying the topcoat; this heats up any air in the resin so it can escape through the surface before it cures.

How do you get even coat of epoxy?

“How do you get even coats of epoxy?” is a question I’ve had to answer on a regular basis over the years. It’s a simple process, but it doesn’t come without its pitfalls, so here’s how we make sure we have great finishes and coatings:

  • MAKE SURE YOU HAVE ENOUGH RESIN FOR THE JOB. We mix our epoxy about a half-a-quarter ounce at a time in big plastic containers, but it usually takes about half an ounce for each coat. The reason for this is that when you’re gluing up several pieces of wood together, it’s better to use too much glue than not enough. You’ll never go wrong if you put on more than what you need because as long as your piece isn’t as thick as your arm, there will still be enough excess to fix minor imperfections.
  • MIX THE RESIN THOROUGHLY AND WELL BEFORE POURING IT OVER THE SURFACE IN A THIN LAYER. This tip comes from hours spent repairing broken furniture and cabinets trying to fix them with the epoxy repair paste—and it works! Mixing the resin thoroughly is especially important if pouring over uneven surfaces or around corners where air bubbles might form. For that matter, doing this for both sides of the piece at once with all the edges will ensure great coverage overall (see tip #3).
  • USE HEAT TO HELP LEVEL THE RESIO FOR BEST COATINGS AND SEALINGS Each application of hardener (the chemical part of resin) has a different consistency; one side may be very thick while another is watery and could cause runs when attempting to apply a second coat or simple drips if not properly dealt with beforehand. The solution? Use heat! Since most modern heat guns are equipped with adjustable temperature settings between 200-300 degrees Fahrenheit, simply spraying your brush/roller/brush roller/whatever tool you’re using in overheated areas

What do you use to finish epoxy?

In order to get the perfect finish on epoxy, you need to sand between each coat. If you don’t do this, there will be visible lines where your coats meet and it won’t look nice.

Sanding after each coat is also a good way to help avoid drips or sags forming. If you can see this starting in your epoxy layer, then sand them using either a rotary tool with a sanding drum attachment or an electric sander. Using an orbital sander will work best for larger areas.

How do you make epoxy clear after sanding?

There are two ways to get a very clear finish: buffing and more sanding.

If you are finished sanding, polishing is the next step. There are many polishing compounds available, but most of them contain a mild abrasive that can dull your finish if it’s not properly rinsed off.

You will also need to find something to put the compound on. The best thing for this purpose is an old t-shirt or other pieces of cloth folded into about a 4″ square, wrapped around your thumb and index finger.

Squeeze the compound into the center of this “pillow” until it forms an inch thick diameter mound; rub it in with your fingers until it’s evenly distributed over the entire surface area of your “pillow.”

The actual act of applying polish is like applying wax from a can: Rub in small circles over an area no larger than 2′ x 2′.

How do you smooth cured epoxy?

The cure is in the sanding…and perhaps heat and polishing!

If you want to achieve a smooth surface on your resin, sanding is an essential step. A common mistake people make is wet-sanding right after pouring the resin before it’s had time to cure.

While this certainly reduces the number of bubbles since they will rise to the top, you should wait until your piece has cured 24-48 hours before beginning any sanding.

As far as grit goes, start with some 600 grit or higher so that you’re not wasting your time with coarser paper. When using a power tool for sanding, be sure to use caution as there is a risk of injury if you don’t follow safety guidelines (for example wearing gloves and goggles).

Make sure not to overheat the resin this can cause discoloration and may even damage the structure of your piece depending on your usage!

For an extra smooth finish, consider using a buffing wheel coupled with a polishing compound.

Can epoxy be used as a finish?

Epoxy resin can be used as a beautiful finish on any surface. Think of epoxy resin as the varnish you would use over stain or paint.

It will not flake, chip, or break off like other finishes, and it gives a beautiful shine to your surface that you won’t believe until you see it! Epoxy resin also comes in many colors as well such as black, blue, clear, and metallic gold and silver.

How do you make resin shiny?

  • Pour your epoxy into a small container and use a heat gun to warm it. Applying the resin at room temperature is OK, but if you want an incredibly smooth finish, applying the resin while it’s warm will help create that effect.
  • Use a brush or spray gun to apply the liquid epoxy. If you’re using a sprayer, keep in mind that spraying helps prevent bubbles from forming but can also cause larger runs, so be careful not to overload your piece with too much resin.


If you’ve followed these steps correctly, you should now have a finished surface that’s smooth and durable. If you’re still having trouble, though, remember:

  • Clean the surface properly. This will ensure your epoxy resin is permanently bonded to the surface.
  • Work in an area that’s well ventilated and warm.
  • Use a heat gun to remove any bubbles that come up after applying your resin. You can also use another solvent alongside this method.
  • Use gloves and protective clothing when working with epoxy resin to avoid getting it on exposed skin or on delicate items like jewelry or watches.
