I thought of using this varnish on the door, in the flower pot class. (The class: How to Paint Impressionistic Flowers in Oil) But I have no idea how to use it.  In Turkish sources, the use on a wooden tray is explained. I could not find an using in the painting.    Can you help me

Crackle varnish usually comes in two parts. You paint the one, let it dry then apply the second one. They then cure at different speeds causing the cracking. You would need to check up on this manufacturers instructions on which goes on when.
