New to resin? Wondering what you should try creating first? How about giving your DIY skills a try by crafting a resin coaster.
What makes resin coasters so awesome?
1. They are fun to make. Resin coaster molds have large open spaces. That means you can include lots of fun things like glitter, beads, candies, and more.
2. I don’t know a coffee table without room for a handcrafted resin coaster.
3. You don’t have to worry about whether a resin coaster fits like you do with a piece of jewelry. Resin coasters accommodate about every beverage that I can think of.
What resin should you use for your DIY coaster?
You must use a resin designed for molds. These resins, also known as casting resins, have an advantage over resin for art. They release bubbles easier, making sure your resin cures crystal-clear. Plus, casting resins cure harder. You don’t have to worry about your coasters getting soft and bendy.
Best resin for coasters:
- Hardens in under 12 hours, so you don’t have to wait long to use your DIY resin coaster set.
- It won’t bend after curing. Your coasters will be durable.
- Zero VOCs.
- USA made.
- Board-certified toxicologist reviewed chemical formula and conforms to ASTM D-4236.
(I get it. That’s a lot of big long words that might buzz over your head. But, the ASTM certification is a BIG FAT HAIRY DEAL. More than two-thirds of art and craft resins don’t have this certification which means their product is unsafe. I’ll get off my soapbox for now, but you can learn why this is important when you purchase resin.)
What resin supplies do you need to DIY a coaster?
You will need a coaster mold, plus resin colors for your epoxy. You will also need mixing supplies, a silicone mat to cover your surface, plus a plastic dome to protect your resin coaster while it cures.
What about resin safety?
Do it. Always. Using resin is like using other chemicals in your home, like bleach or ant killer. Ensure you’ve got good air movement in your room and wear protective gloves. Taking appropriate resin safety precautions is vital to having fun with resin for a very long time.
Ready to make that coaster? Let’s do this.
For this DIY resin coaster project, I’m making a resin coaster formed to look like a sunflower. It’s the cutest coaster ever for your she-shed.
Resin coaster supplies:
- Resin Obsession super clear resin
- Pearl Ex powder pigments for resin
- Mixing cups
- Stirring sticks
- Safety gloves
- Acrylic paint
- Silicone mat or plastic sheeting to protect your table
- Plastic bin or box
Step 1: Prep your area
This might be the most challenging part of making this DIY resin coaster. You need to craft somewhere you, and everyone else can leave the coaster alone for a couple of days. I’ve written you a fill-in-the-blank excuse in case you have to use the kitchen table and can’t make dinner. (You’re welcome.). Put that silicone mat down and get your supplies on that mat.
Step 2: Measure the mold
Did I forget to mention there’s a little bit of math here? Yeah, sorry about that. But, you don’t want to mix too much resin only to waste it or not mix enough resin that you can’t fill the mold all the way. So grab your measurements, then plug them into our resin calculator. It will tell you how much resin to mix. Spoiler — if you’re using the sunflower mold I’m using here, you want to mix 2 1/4 ounces of resin.
Step 3: Color the mold
Grab your paintbrush, then dust powder pigment into the coaster to give it the DIY flare it deserves. I went traditional and colored the petals with Pearl Ex Solar Gold, but have it your way. There are actually some pretty unusual sunflower colors.
Work with one color before adding the second color.
For the center, I used Pearl Ex dark brown.
Tap out the excess powder.
Step 4: Add resin
I mixed my clear epoxy and poured it into the mold.
Mixing resin is a topic in itself. If this is new to you, read how to mix resin in five easy steps so you know exactly how to conquer this step.
Step 5: Remove bubbles
Look over your coaster and see if any bubbles are floating on the surface. Then, scoop them out with your stirring stick, or go over the surface with a heat gun.
Pro tip: Bubbles can hang in the edges and corners of a mold. Get a bright light to check for these little devils. Use a toothpick to bring them to the surface, then pop them like the resin boss you are.
Once your resin is bubble-free, cover it with your container and let it cure.
Step 6: Demold
Gently pull the mold away from the coaster while grabbing an edge. Your coaster will lift out of the mold.
[OPTIONAL] Step 7: Highlight details
Get your paint, then brush it into the flower recesses. This brings your flower to life.
It’s okay to get a little sloppy.
Before letting the paint dry, wipe off the big streaks with a paper towel.
If you have long fingernails, you can use them to scrape off the excess. Don’t lose your mind trying to get all the extra paint off. We’ll take care of that in the next step.
Let the paint dry for a day.
Step 8: Finish
Use a piece of sticky tape to pull off any remaining paint. Rub the tape across your DIY coaster surface and watch the resin come clean.
So how did the DIY resin coaster turn out?
I’d say pretty good. Resin coasters are definitely more than just for man caves.
And as you can see, it holds my Betty Buzz beverage like a new resin coaster should. We only just met, but Betty and I are total BFFs.
