Bottle cap coasters are the perfect man cave gift. Get a few bottle caps off your guy’s favorite adult beverage, add some resin and you have an instant favorite gift!
- Resin Obsession super clear epoxy resin 6 ounce kit
- Round beverage coaster mold 431
- Castin’ Craft mold release and conditioner
- Resin Obsession Stir Stix
- Reusable plastic cups 10 ounces
- Reusable plastic cups 1 ounce
- Castin’ Craft yellow opaque resin dye
- Nitrile Gloves
- Bottle caps
- Wax paper (great to put down before working the resin — in case you have a spill)
- Drinking straw
- Large dome
Apply a light mist of the mold release to your coaster mold and allow to dry (this takes about 20 to 30 minutes).
Measure the amount of resin needed for your coaster. (I mixed a total of 1 1/2 ounces for the first pour.)
Note: I measured the amount of resin (1 ounce) and hardener (1/2 ounce) in small medicine cups to make sure I got the proper measurements. I then mixed them together in the larger measuring cup.
Gently pour your resin into the mold in a thin stream. This will help you avoid making bubbles into your resin.
Once your mold is half full (or a little more), gently place your bottle caps into the resin.
Hint: You want to put the resin in first because placing the bottle caps first, then pouring the resin, may cause you to trap air bubbles underneath the bottle caps.
Use your stir stix to gently push the bottle caps into the desired placement. Add in any remaining resin and scoop resin into the bottle caps if necessary.
Using a drinking straw, blow lightly over the top of the resin to remove any bubbles.
Be careful not to inhale the resin!
Cover with a dome and allow to cure.
After your first layer has (at least partially) cured, mix another 3/4 to 1 ounce of resin. Add the color to this mixed resin.
Hint: Add one drop at a time, then mix in thoroughly. You only want to add as much as you need to in order to get your desired color.
Pour the layer of colored resin over top the layer of clear resin and bottle caps.
Use the stir stix to evenly spread the resin over the top of the bottle caps.
Cover and allow to fully cure.
Once the resin has cured (approximately 24 hours), flip the coaster mold over. Gently push from the back while twisting the mold. Your casting should pop out.
Sand the rough edges off your resin coaster with a 600 grit wet/dry sandpaper. Wet the sandpaper first.
Hint: If you’re worried the coaster may scratch a delicate surface, glue cork and/or felt pieces to the bottom to elevate the edges of the coaster.
Enjoy your new resin coaster!
