How to Use Epoxy Glue
- First, prepare the surfaces you will be bonding by sanding to roughen them up a bit. This will make it easier for them to bond.
- Next, take any kind of disposable surface you have to dispense the resin and hardener onto.
- When you have dispensed both epoxy parts onto the disposable surface, you can mix them together with some kind of disposable mixer.
- After that, you can apply a small amount of epoxy to the surfaces you are bonding and press them together carefully so they don't lose their position.
- Finally, carefully clean up any excess epoxy and allow the surfaces to cure fully.
