Two part epoxy is the subject of this woodworking tips card, and as a beginner, knowing your adhesives can help. At first, you should only worry about two. Wood Glue, which was already covered in a different tip, and two part epoxy, which is covered here.
Two Part Epoxy and Gluing things Together
As a new woodworker, you will be working with wood for the majority of the time. However, there will be instances where you need to glue something else. These times are when two part epoxy comes in handy.
There are a couple types of epoxy, but they all work through a chemical reaction. You mix the two parts according to the directions, and apply them in between what you are gluing together.
The real difference between epoxies is the amount of open time that you can use the product. There are epoxies that you can buy that will have 60, 30, or 5 minutes of open time. This is the time you have to get it applied before it starts to set.
For most small gluing applications, the five minute is good. If you need more time, like for inlay work, then look for the 30 or 60 minute. Either way, you are going to have to wait about 24 hours in most cases for a full cure, so don’t buy one because you think it’s going to cure faster.
Epoxy shines when you have to glue almost anything to almost anything else. It’s like a small miracle in a tube, and it bonds nearly any two objects together really well.
Epoxy Help and Tips
Buy a name brand epoxy that you have heard of before or that you know has been on the market a long time. Woodworkers skimp on stuff like this and it’s not worth it. You will not need much epoxy for any small project. You can spend a little more on a nice product and not break the bank.
Also, when you are mixing the product, follow the directions. Most of the time, the product is mixed in equal parts. However, if you add more hardener it will cure faster. If you add too much, it will become brittle. Alternatively, if you add too little, it will either take forever to cure or never cure. This is awful, so make sure to pay attention.
Lastly, mix your epoxy well. Use the back side of a used piece of sandpaper, or something that will be thrown away after use. Epoxy is tough stuff, so you will never get it off the bench if you mix it on there.
