Why make a bottle cap coaster?
You can finally do something with that cool collection of bottle caps you have.
Besides, they’re perfect for man caves and make great DIY Father’s Day gifts.

Step 1: Prep the mold
Apply a light mist of the mold release to your coaster mold and allow it to dry for at least 30 minutes.
Step 2: Measure and mix resin
Mix Part A and B together until it’s clear and streak free.
⭐️ BONUS: If you’ve never mixed epoxy before, here are all the details on how to mix resin.
Step 3: Add to the mold
Pour your mixed resin into the mold.
Step 4: Add bottle caps
Once you’ve got a thin layer of resin in the mold, place a bottle cap into the coaster mold.
💡 Pro tip: Dip the face of your bottle caps in resin, then put them in the mold. This keeps you from trapping resin bubbles.
Use your stirring stick to push your bottle caps around. Add the rest of your epoxy to the mold.
Step 5: Remove bubbles
Use a heat gun to go over the top of the resin to remove bubbles. Then, cover it with your plastic dome and allow to cure.
Step 6: Mix the second resin layer
Mix enough resin to fill the mold. (Use the resin calculator again if you need to.) Add the yellow pigment to the clear resin.
Step 7: Pour the resin into the mold
Pour yellow resin over the top of the layer of clear resin and bottle caps.
Remove bubbles with your heat gun. Then, cover and allow to dry.
Step 8: Demold the bottle cap resin coaster
Once the resin is dry, you can demold your bottle cap coaster. Push from the back while twisting the mold. Grab a coaster edge and peel it from the mold.
Step 9: Sand edges
Sand any rough edges with a 600-grit wet/dry sandpaper. Wet the sandpaper first.
💡 Pro tip: If you’re worried the coaster may scratch a surface, glue cork or felt pieces to the bottom.
