Mixing with Drill Motor Mixers
A variety of motor-driven mixers can be used to thoroughly mix epoxy. They are essentially paint mixers or variation of paint mixers chucked into a variable speed drill. When mixing with a motorized mixer, we recommend the following three-step approach:

1. Mix for 30 seconds with a drill motor mixer.
2. Stir by hand with the measuring stick, thoroughly scraping the corners and sides.
3. Mix for 15 to 30 seconds more to blend completely.

Quality Control
Before mixing that big batch, consider quality control. Resin and hardener must be thoroughly mixed. We all know this, but tend to forget during big projects when we’re pressed for time. This is not the place to look for short-cuts. If you don’t follow certain guidelines, a fancy electric mixer will not make up for it.
