Epoxy Doming - 6 Practical Tips

Do you want to professionally finish your epoxy art with a shiny, beautiful finish? Here are some practical tips from our experts.


A commonly used technique when working with epoxy is ' doming '. You apply a thin layer of epoxy on top of your epoxy resin art. This gives a nice glossy finish with a small bulge. Now it really feels like your creation is completely finished!

See example below. The dotted line on top of the epoxy artwork shows where a thin layer of epoxy will soon be placed.

1. Use the correct epoxy

Choose a quality epoxy that is suitable for doming. Make sure this epoxy is transparent and UV resistant for a smooth end result.

The most commonly used epoxy resin for this is the UV Resin - Jewelry Epoxy Resin . This is also a thicker epoxy. You spray this directly from the bottle so you don't have to mix it.

You can also use a small amount of transparent two-part epoxy with high viscosity. We recommend the Epoxy casting resin 1:1 for this . This epoxy is easy to use and thicker (high viscosity) than other epoxy resins. You can pour transparently or mix epoxy with pigment in advance and apply it on top of your creation with a stirring spatula . Add a little bit each time, being careful not to let the epoxy flow over the edges.

Use a high viscosity epoxy for this or let your epoxy mixture rest for 10-15 minutes so that the epoxy thickens slightly. Ideally, the epoxy is viscous when you start working with it.

2. Use the right tools

For example, use a skewer or pipette for small creations and a wooden spatula for larger creations . The finer the tools you work with, the more precise you can work.

3. Work carefully

Firstly, always work on a flat surface and make sure your table is level so that your epoxy will not flow over the edges. Know that doming only works on flat pieces of epoxy.

Make sure the surface of your creation is clean and dry before you start. Remove dust, dirt and any grease residues to ensure good adhesion of the epoxy.

Always start in the center and then spread the epoxy to the edges. Be careful not to apply too much epoxy, add it drop by drop if necessary. There is a tension on the epoxy, if you work too fast it can snap and the epoxy will flow around the edges.

4. Protect your creation

Once you have applied your doming layer, place a container over your creation. This way, no dust or hair will get on your creation and you will soon have a really shiny, beautiful finish. Continue to step 4 and do not let your epoxy harden yet.

5. Let the epoxy rest for a while

A common mistake with epoxy doming is not allowing the epoxy to rest properly after pouring. Let it sit for 5-10 minutes to allow epoxy air bubbles to rise to the surface. Then remove the air bubbles and (see: removing air bubbles from epoxy ) allow to harden according to the epoxy's instructions for use. If you don't do this, you will end up with a surface with small craters/holes or streaks from the mixing spatula.

6. Cleaning

Then wash your creation with soap and water to remove any stickiness.
