Dala Crazy Cracks (Crackle Glaze) is a ‘sandwich crack’, often referred to as Crackle Glaze. It is applied between two layers of acrylic paint, causing the top layer to crack during drying.
This crackle affect is very successfully used to imitate the look of aged paint or leather.
Paint a layer of acrylic onto your surface. Follow this with a layer of Crazy Cracks and finally, apply the second layer of acrylic paint over the Crazy Cracks. Allow each layer to dry before applying the next coat. The topcoat will crack and expose the colour of the bottom coat. Complementary or contrasting colours may be used for more effect.
If you paint the crazy cracks from top to bottom the topcoat will crack in vertical lines. If you apply the crazy cracks from side to side the topcoat will crack in horizontal lines.
Do all acrylics work with Dala Crazy Cracks? Most acrylics will be cracked by this glaze but they will not all crack in the same way. The PVC (Pigment volume content) of the topcoat largely determines the type of crack. The higher the PVC, the more regular the cracks will be. Lower PVC paints exhibit irregular wider cracks. This is because the lower PVC paints are more flexible than high PVC paints. 'Craft Paints' or 'Folk Art Paints' usually have high PVC for hiding power and will give you an excellent regular crack. On the other hand, 'Fine Art Acrylics' will have lower PVC, because they need to be flexible for their thick application. These acrylics will mostly give you an irregular crack.
Never over paint your topcoat. Work quickly and in one direction. Load your brush with enough paint to move from top to bottom or left to right. If you over paint this layer you will force the paint into the crazy cracks and this will result in very faint cracks or none at all.
