Step one

With a stir stick we mix  slowly the two resin parts: A and B (resin and hardener) according to the manufacturer's instructions. Normally the ratio is A2: B1. We will use a scale to measure grams. Here is necessary to use surgical mask to protect us.
We let the mixture rest for a couple of minutes under a lamp. Bubbles can rise and can be moved to the side of the cup and "popped" with a toothpick.
