Hi, I'm a beginner with this new hobby (Resin Art) and bought the Envirotex Lite just to see how it works. Did the measures with volume and also using the scales, mixing with the timer and did all the things I should do. Unfortunately, my small projects won't cure the way I thought it would be. It's bendable and not hard even after 2 or more days. What can I do more to get it right? Any suggestions are most welcome.
