Home-Made Crackle Glaze and how to use it
1. Dilute (a little) some PVA glue with water and apply a layer of the glue onto a primed or painted surface.
2. Before it’s dry, apply another coat of paint (can be a different colour or same as the first coat) but make sure you apply all the strokes of paint in one direction only. As the paint and glue dry at different rates, the top surface cracks open and gives it the ‘crackle’.
