Introduction: DIY Resin & Wood Coasters

About: Hi, I’m Sam! Full time psychologist and woodworker! I build things and publish plans. Check out my website and YouTube channel for more project ideas!

I’m all about using things I already have laying around my shop (since, I’m basically a lumber hoarder). So, when I had some off-cuts available to use from a previous project I knew I wanted to save them for a resin and wood coaster project. Even cooler, I had some deep pour epoxy leftover as well and made good use of that too! This is a project that has been on my list for a while, and I’m so excited to share it with you!

Materials
Wood (I used Maple Burl I Purchased from Ebay)
Epoxy Resin (I used a Deep Pour Epoxy)
Silicone Coaster Molds
Ink Dye
Penetrating Finish

Step 1: Prep the Wood

Cut your wood pieces to fit in your silicone molds. The maple burl I used was too thick for the molds, so I used a bandsaw to cut them to a size that was slightly thicker than the depth of the molds. I then used my miter saw to trim the pieces to size so they’d fit snugly inside the molds.

Step 2: Prep the Molds

Next, clamp your wood pieces inside of your molds so they don’t float when you pour the resin.

Step 3: Prep the Resin

Once the molds have been prepped, mix your epoxy resin according to the directions on the bottle. Mine was a 3:1 ratio deep pour product, so I was able to mix and pour the full depth amount in one shot. You can also add color as well – I chose a few drops of turquoise dye for mine!

Step 4: Pour the Resin

Pour your resin! Make sure to use a torch or a heat gun to remove any air bubbles from the surface of the pour.

Step 5: Remove From Molds

After the pour cures (this will depend on what type of resin you use), de-mold the coasters from the forms.

Step 6: Sand Away!

Next comes sanding! I started with 80 grit sanding discs to smooth the coasters flat and then gradually worked my way to 320 grit with the sander.

Once you’re done sanding with the sander, use hand sanding to smooth the rest of the coasters. I used a wet sanding method with waterproof sandpaper. I worked my way from 400 to 600 grit with this method.

Step 7: Seal

After sanding, allow the pieces to dry and then apply a finish. I used a penetrating oil finish for my coasters, but you can use whatever works for you!

Step 8: Enjoy!

Allow time to dry, and then use them in your home!

    Wow! These look so cool!! I have a question, if you don't mind. Did you pour your resin to cover the wood? In the earlier pictures it looks like the wood pieces are the same depth as the moulds but in the last couple it looks like the wood is only half the depth of the finished coaster. Or did you put some kind of base onto the bottom of the coaster? My daughter is experimenting with resin pours and this looks like something she would love to try.

    Hi! Resin and wood were completely level when I was done. Hope you'll share her project with me when she's done!

    Thank you! That happened because of the shape of the molds I used. You can see it better in action in the video when I peel the mold away from the cured coasters. There's a small inset in the coasters help hold any moisture that comes off of the cups.

    Question 11 months ago

    Hi, these do look very cool, lovely wood. One question please: how did you sand the inside surface of the coaster? It looks like it would be quite hard getting a flat clean surface due to the raised edge on the coaster. Thanks.

    Hi! I didn't have to sand the inside very much, as it was mostly covered in resin where it needed to be! I just hand sanded small spots.
