Should I Warm Epoxy Resin In A Water Bath Before Mixing?

Yes, we recommend using a warm water bath for your resin and hardener prior to mixing because epoxy resin is generally easier to work with and has less bubbles when it's warmer.  Here's how:

Place your tightly capped bottles of resin and hardener in a container of hot ( not boiling ) water.
Let the bottles sit in the water bath for 15 minutes or so ( depending on how cold your resin was to start with and how hot your water is. )
Dry your bottles off thoroughly before opening them (because even a single drop of water in your resin or hardener can cause your resin to cure cloudy. )
Since curing is accelerated by heat, keep in mind that warming your resin in a water bath cuts down your 45 minute working time by about 10 minutes, so time yourself accordingly.

The ideal working temperature for working with ArtResin is 75-85F, so if you're working with it in the summer, you may not need a water bath; if you're working in the winter, however, a warm water bath before you measure and mix is a good idea. 

How long should I let my epoxy resin sit in a water bath for?
Well, that really depends on how hot your water is. Generally we like to use water the same temperature as you would for a bath ( ie not boiling water - you don't want to melt the plastic bottles! ) and we leave it in for about 10-15 minutes total.
