I have heard from a few readers who are having trouble with their resin projects, who never had issues before.
After mixing incorrectly, I believe temperature is the next major reason why anyone would experience an imperfect cure.
If you work in a basement or a garage cold will effect your cure. When winter sets in, you may need to move your resin projects to a warmer place inside (depending on where you live of course.)
Question: I have heard resin does not work in the cold. Can you tell me why?
The Carmi answer is resin would not join a hockey team. Hehehe.
In other words, Envirotex Lite and the ETI line of resins need to be mixed and cured in a warmish room. Envirotex Lite (and all other two-part epoxies) are reactive compounds that require warm temperatures. The absence of heat means that they will not cure. Heat/warmth is the part of the process you control by planning when and where you will be mixing and pouring a batch of resin.
70 degrees Fahrenheit or
21 degrees Celsius at all times please!
