Don't waste $ on expensive 'crackle finish' paints, good ol' white school glue works! Instructions: 1.Paint wood surface with base coat paint and allow to dry thoroughly. 2.Brush White Glue on top of base coat. (A thicker coat results in larger cracks - apply a thinner coat for fine cracks.) 3.While glue is tacky, brush on top coat. 4.Dry completely.
