Resin, also called epoxy, has really taken the woodworking world by storm. Lots of woodworkers have become intrigued by resin and what it can add to their projects. This medium provides lots of room for creativity, but if it isn’t used correctly, there can be a myriad of problems. It all starts with making sure you’re mixing the resin correctly, and Jess Crow will help us with that.
There’s more to mixing resin than simply pouring it in a bucket and stirring it up. You’ve got to make sure:
- Your shop temp is correct
- The resin-to-hardener proportion is right
- The time spent mixing is right
- You don’t mix too aggressively or not aggressively enough
- You understand how humidity affects resin
- You understand how to use resin pumps
- You have solvent for cleaning up resin
- You know how to use calibrated measuring cups
About Jess Crow
We’re very lucky to have Jess Crow helping us on this video. She’s a resin artist and an expert in the field. You can check out her work on Instagram @crowcreekdesigns. When it comes to mixing resin, Jess knows some great tips, and she’s very willing to share them with us.
Jess will be working with MakerPoxy. If you’d like to know more about resin and how to work with it, but sure to have a look at the rest of WWGOA’s content about resin.
Nice video, except everything she said can be found on the bottles, i.e. mix =parts, stir and pour. Gloves are a given unless you like the stuff all over your hands.
What I’d like to know is how can you tell if the mixture’s right before you pour and whether to us a hair dryer, torch or heat gun to get rid of bubbles.
Yep, as long as people read all of the manufacturer’s directions they’ll be in pretty good shape, but it’s nice to get tips from the pros, too.
You probably caught Jess recommending 3 minutes mixing time in the video. Make sure you pull the stir stick along the side and bottom of the cup so you have all the resin and all the hardener pulled into the mix. Mix thoroughly but not aggressively. That recipe will get you a complete mix.
A heat gun will work in most cases. You might need a torch on a deep pour, but start with a heat gun first.
Thanks for sharing.. Great tips…
Very good tips. Two comments: First, not all two-part resins are epoxy. One of the most popular for use in making woodturning blanks, Alumilite, is a urethane resin.
Second, because there are lots of different types of resin, users NEED to read the instructions. As shown in the video, resins vary in the ratio of ‘part A’ to ‘part B’. Some, as shown in the video, are measured by volume. Others, are measured by weight. Some have a very short pot life, while others take days to cure. Some can be used for a thick casting, others can only be used for coating an object. You have to make sure the resin you’re using is ‘right’ for the job. If not, you’re apt to be disapointed.
