How to Make Resin Coasters
I get so many compliments from these coasters. They are such a big hit I have been giving them out as hostess gifts. This project is so simple, even though it might looked complicated.
- Resin Kit
- acrylic paints
- glitter (optional)
- wax paper
- disposable cups
- take out food containers
- Popsicle sticks or plastic utensils
- rubber gloves (medical gloves)
- disposable measuring cups (medicine cups are the best)
My Favorite Resin Kit
There are different types of resin. Epoxy Resin is best to use when you are a beginner. Most professional work in Polyester Resin, which produces a better quality piece, however polyester resin has dangerous vapors so a mask and well ventilated work place is a must.
I highly recommend using Epoxy Resin for this project it is a low odor resin and does not require a mask, you must wear gloves when dealing with resin. I buy a box of medical gloves from my local drug store.
I use round plastic take out containers I get from my Indian and Chinese food restaurants. Stay away from hard Tupperware type or really thin or colored plastic container ie butter container.
Butter container will work but they usually rip when trying to remove the resin so they can not be reused.
Lay wax paper on your work space. I tend to tape down the paper, because resin is pretty hard to get off any surface. Using Wax Paper is a must, foil or newspaper are not recommended.
The best way to determine the amount of resin needed for a certain mold is to fill the mold to the amount you would like to use with water and measure it. When working with resin exact measurements are a must! With my molds I use 2 ounces of resin for each coaster.
Resin Kit comes in 2 parts. Do not mix the parts together until you are ready to pour into a mold. The two bottles of the kit consist of Resin and Hardener. Follow the direction of the kit on how to mix and measurement. The usual rule of thumb is 1 to 1 in measuring.
Use two measuring cups I label one with an R for Resin and one for H for Hardener ( see pic #1)
Always, wear gloves when working with the Resin.
Mixing and Coloring Resin
If your mold requires 2 ounces of resin. Then fill one measuring cup with an ounce of resin and another measuring cup with an ounce of hardener, since it is a 1 to 1 ratio.
*one rule of thumb is the bottle of resin and the bottle of hardener should always be at the same level after each project. If they are not, then that means there was an incorrect measured project which means that the item will probably not harden.
- Add the resin and the hardener to the disposable cup.
- Mix together as instructed by the kit using Once properly mixed (picture# 2).
- I advise adding color. Clear resin is hard to pull off it tends to come out cloudy or bubbly. Acrylic paint works well and adds vibrant color. Only a little color is need as seen in (picture #3).
- Mix the resin until color is even and the desired hue (picture #4). If you want a more milky color or cloudy finish then add a white paint to your resin.
- Pour resin from cup into the mold. Bubbles/foam is normal after mixing and will disappear after setting (see pic below) after about 5 min after pouring to the mold the resin should appear clear.
If using many different color you must use a different cup and mixing utensil each time.
*** I recommend throwing away all cups, measuring cups, gloves, and mixing utensils into a plastic bag and tie the bag securely to make sure the resin does not get on any other surface.***
All that glitters
I like to add glitter to my coaster for added interest and sparkle. For this project I love the chunky glitter. Regular glitter will work well too. Once resin is in the mold sprinkle glitter and mix so the glitter will be seen from the bottom of the coaster too. If too much glitter sinks into resin I sprinkle some extra on top and do not stir.
Recommended Glitter for this project
Leave resin filled molds on wax paper to set. It takes about 24 to 36 hours to harden properly. Once the resin has harden completely. Turn the mold upside down and push down. The resin should loosen. Once the bottom loosen, turn over mold and press the sides away from the resin. The resin should easily pop out from the mold.
If the resin does not want to come out of the mold try putting the item in the freezer for 15 min and try to remove again. If it is still stuck try cutting it out of the mold.
Trim any excess resin on the sides.
