We are proud to be carrying KROMA Crackle. It is THE premier crackle medium on the market today.

KROMA Crackle is a versatile, professional quality material suitable for all kinds of fine art applications and craft projects. It is a semi-opaque gel that develops fine cracking patterns as it dries. It can be applied to both rigid and flexible surfaces and once dry and sealed is both durable and highly flexible. KROMA crackle can be coloured by adding small amounts of acrylic paint before application or by painting over the crackle once it has dried. Experimenting with application methods can influence the texture of the crackle to achieve different looks with limitless creative possibilities.

How is Kroma Crackle different from other crackle products? 
There are several different types of crackle mediums on the market. Some are two part systems that depend on a chemical reaction to create cracks and tend to emulate the effect of peeling paint on weathered wood. Others are heavy pastes that can be used only on rigid supports and create chalky surfaces with wider cracks. 
KROMA crackle is a semi opaque gel that cracks as it dries. Used straight from the tube it will dry white. It can be used on flexible surfaces and remains flexible once dry and sealed. It is a very versatile and can be used in different ways to produce different cracking effects. 

What Surfaces can I use Kroma Crackle on?
Kroma crackle can be used on both rigid and flexible surfaces such as paper, fabric, leather, canvas, wood, and metal. An absorbent surface such as canvas or paper should be sealed with a layer of acrylic paint or clear acrylic medium before applying crackle. Very smooth surfaces such as metal should be sanded before applying crackle to ensure adhesion.

How thick should I apply Kroma Crackle?
For visible cracks to form KROMA crackle should be applied in a layer at least 1mm thick. Thicker applications will create wider cracks. If the layer of crackle is too thin very little cracking will occur or the cracks will be hardly visible. To ensure a thick enough layer is applied we recommend using a palette knife or similar tool to spread the crackle gel. Using a brush tends to make it more difficult to achieve a layer of adequate thickness for effective cracking to occur.

How do I clean up Kroma Crackle?
KROMA crackle is water based and cleans up easily using soap and water.

How long does Kroma Crackle take to dry?
  The drying time will depend on the surface it is drying on, the thickness of its application, and the environment in which it is drying. More absorbent surfaces take longer to dry, while sealed or non-absorbent surfaces have shorter drying times. Thicker application will take considerably more time to dry than thinner application. While cracks will begin to appear within a few hours, generally KROMA crackle will take between one and three days to fully dry.

Can I speed up the drying time?
It is possible to speed up the drying time using a heat tool if a layer of pva  (white) glue is applied before the crackle layer. See DeMeng’s demented derma technique for step-by-step instructions to achieve this effect.  It is also possible to use a heat tool to complete the drying process once cracks have already formed. Both these techniques produce irregular cracking effects that are quite different from allowing crackle to dry naturally.  

Is Kroma Crackle available in different colours?
Kroma crackle is a semi-opaque gel that dries white. Currently we do not manufacture crackle in different colours, but you can tint the crackle gel by adding small amounts of colour before applying or after drying using acrylic or other water-based paints or inks.
 
Can I mix paint with Kroma Crackle?
Yes - adding small amounts of acrylic paint - up to 5% - before applying crackle allows you to create any crackle colour you wish.  Adding larger amounts of paint will prevent cracks from forming. You can create unusual “marble” type effects by swirling together portions of differently coloured crackle gel. Alternatively colour effects can be achieved by using the crackle gel straight from the tube, allowing it to dry fully and then applying colour using any combination of washes, stains, sprays or dry brush techniques.

What other materials can I use Kroma Crackle with?
Kroma Crackle is ideal for adding texture to mixed media work. Once dry it can be used with watercolours, markers, inks, spray-paints, punches, and stamps.
 
Does Kroma Crackle need to be sealed? 
To produce a durable and flexible finish Kroma Crackle should be sealed with a layer of acrylic medium. A fluid acrylic medium diluted with water will absorb into the crackle surface most readily and will create a strong bond with the surface it is applied to, without altering the appearance of the cracked surface. Acrylic gel mediums or acrylic paint are also effective in sealing the surface but will produce a flatter texture more like leather, and less like a parched desert. For projects that require folding or handling the surface, sealing is essential.
 
Is Kroma Crackle archival quality?
Yes, when used with other archival quality materials, and sealed with acrylic medium Kroma Crackle is durable, flexible and of archival quality.
