How to Make a Resin Coaster?
Supplies you'll need
Before going into the details of making a resin coaster, let’s have a look at the supplies you need.
- A well-ventilated workspace
- Protective equipment
- Container for mixing
- Resin with its hardener
- Resin coaster molds - any of your choices
- Sticks for mixing
- Colorants of your choice
- Any decorative item you want to add to your coaster
Step by step instructions
Now that you have assembled all the supplies, let’s take you through the process of making a resin coaster, one step at a time.
1. Preparation of resin
The first thing you need to do is mix the resin and hardener in the right ratio (i.e., 1:1 mostly). Immerse the closed containers of hardener and resin in a bowl of warm water prior to mixing. It is preferable to work with resin in warmer temperatures in the range 22 – 25˚C. pour equal amounts of resin and hardener in a bowl and mix thoroughly with wooden sticks. Once you’ve mixed the resin and hardener in the correct proportion, there's very little that can go wrong.
2. Adding colorants
When it comes to coloring your resin, you can use the following colorants:
- Powdered pigments
- Resin dyes
- Alcohol ink
Whichever type of colorant is being used, it should be added after mixing resin and hardener. The amount of colorant should not exceed 6% the total mixture of resin. The colorant should be added slowly and mix with a toothpick.
3. Pouring the resin into the mold and embedding items
The next thing to do is to pour the mixed resin into the coaster molds. The trick is to coat the base of the mold with a thin layer of resin. In a separate bowl take a portion of your resin and immerse your embed items in the resin. Once they’ve fully coated with the resin, put them over the thin resin layer in your mold. After that add another layer of resin to fully cover the embed items.
4. Get rid of any air bubbles present
Adding the embellishments into the resin can give rise to the formation of air bubbles. You can avoid bubble formation by not moving your embed items too much. However, if bubbles do form, its nothing that can’t be fixed. Use a straw to blow at these bubbles to remove them. You can also use butane torch for this purpose.
All you have to do now is wait for your resin coaster to dry properly. Once it has hardened, take it out of the mold carefully. Congratulations! Your first resin coaster is ready to use.
