Beginner's guide to resin doming

All you need to know on how to dome your pieces with resin


Doming your resin is an effective way to add finish to your pieces, it makes your work appear much more valuable, shiny and professional.

If you’re just getting started making beautiful resin pieces or you’re looking to learn more on how you can make your resin pieces look a bit more finished... maybe you aren’t certain how to get started, these tips will walk you through the entire process of how to achieve the doming technique. 

Let's get into it

1: How does doming work

Doming is a great way to give your work a glass-looking finish. However, it only works on flat and leveled surfaces as you will need to use the surface tension of the resin, which is basically the resin’s surface that holds the liquid, to create that dome like shape. So ensure that whatever piece you are about to dome is flat with a straight edge.

In spite of your work having a leveled surface, not all resins are able to dome or dome properly because they do not have the right type of viscosity, which is the thickness of the resin. It is crucial for you to select the right type of resin for a successful outcome, which would be resin with a higher viscosity, meaning it is much thicker. 

If you’re also applying resin to porous materials such as wood and paper, these materials would require proper sealing, you can seal these using mediums such as mod podge to prevent the material from staining.

2: Sanding the edges

Once you have the leveled piece that you are going to dome, which could be completely flat or have a concave edge like the pieces depicted in this article, the first thing you’ll do is to sand the edges slightly to ensure that they are even. However, be careful not to sand off the edges completely as you want to keep that concave shape, which allows the resin to stay in place and hold the dome shape.

To do this use a wet and dry sanding sponge with a fine grit. Spray a few spritzes of water on to your sanding sponge to help with the dust particles and gently sand the edges of your piece.

3: Doming the pieces

Once your edges are leveled enough, place your pieces on a silicon mat to prevent them from moving around when you’re doming. It will also help you to peel your piece off in case of spillage, after it’s cured.

Other options are silicone drying mats or trivets to avoid resin spillage underneath your pieces.

To start the doming process, pour or use a spreader to apply a small amount of resin on to your piece. Always start with small amounts to avoid over spillage as you can always add more later.

Move the resin to the edges carefully with your spreader, toothpick or even your scraper tool. While you’re doing this try not to break the surface tension during the process, it’s the surface tension that makes the doming effect. Look at your piece from all different angles to make sure the whole surface is covered with resin.

If during the process you realize that your resin has a low viscosity, wait for it to get a bit thicker before applying the second layer. It will make your doming process easier, and the dome will be fuller.

4: Eliminate surface bubbles

When you’re satisfied with your dome, run your lighter along the surface to pop any surface bubbles. You then want to cover your pieces while they cure to prevent dust from sticking to the resin. 

If you wish, you can dome the other side once the resin is fully cured. Just don’t rush the process or you might ruin it, if you try to dome the other side before it’s solid.

5: Adding the finish

You have many options to finish your pieces, you can turn them into charms or pendants by adding glue-on bails or eye screws.

For glue-on bails you want to use industrial glues or two-part epoxy glue and make sure to apply the glue on the textured side. You can even embed the bails during the doming process.

For eye screws, either a hand drill or a dremel tool can be used to make a hole. Apply some glue on the eye screw and screw  it in, top it off with a jump ring and you’re all done.

Another idea is to glue some craft magnets on the back  and you can use them for metallic boards or even decorations for your fridge!

Get your creativity flowing and find your own ways to use the resin pieces. It’s all up to you!
