A non-yellowing acrylic medium which produces consistent cracking of emulsion paint to create two-colour ageing and dramatic effects. Apply a base coat of emulsion paint [the colour of the cracks] and allow to dry. Then apply a smooth coat of Crackle Glaze brushing in one direction only. Allow to dry. Then apply the top coat of emulsion paint [thinned 10%] brushing at right angles to the glaze using a loaded brush in one pass only. Cracks will appear in the top coat revealing the base colour, the thicker the top coat, the larger the cracks. Coverage 15m2/litre.
