Hi,
I am pouring a 15×15 cm first layer with a depth of 4mm. I wait the allocated manufacturer time and pour the second 4mm layer. Both batches of resin have no or very few bubbles.
However, I am finding that air bubbles form on the surface of the first layer when I pour the second layer on top. This issue does not occur on the other parts of the craft (e.g. the surface of the photo).
Do I need to wait longer to pour the second layer, or is there something else I am doing incorrectly?
Thanks in advance for your advice.
