Crackle varnish (1 or 2 steps) 1 step - 100 ml

These water-based varnishes create a crackle effect on acrylic paint or any water-based paint. It is colour less and your result will be totally transparent. The varnish in 2 steps makes it possible to obtain a finer and more delicate rendering than the medium 1 stage. This one will create bigger and less regular cracks.

You can use this effect to create beautiful pearls, cabochons, pendants, to customize your decorative objects or creations in Darwi self-hardening clay. Use a Darwi Acryl Metal paint to get gold, silver or bronze cracks! This will have a foil effect! On a dark background, you can better appreciate the result. Change the effect by using a dark colour on a light background, this will give an old appearance to the varnished surface.

To vary the effects, change the application methods of paints and varnishes cracking (thin and thick layers, direction of the application). If you apply thin layers, the cracks will be smaller. The thicker the layers, the more important the cracks will be. With the two-steps varnish, vary the two layers of layers to obtain various effects.

The two-stages crackle varnish is also used alone on Cernit polymer clay to give it an aged appearance. Then skate with Indian ink ink or wax to reinforce this aspect.

How to use the Darwi crackling varnishes?

For these products, you can choose a brush or sponge application. The rendering of the cracks will vary according to your choice of application: instrument, direction of application, thickness of the layers. Start by testing the application and rendering on a "rough" surface.

Attention, apply the varnish only once in places. Do not iron several times at the same place as the effect may be affected.

• For Darwi 1 step cracking medium (100 or 250 ml bottles): If you want a background of colour to your cracks, paint your support with an acrylic paint. You can leave it as it is. Once the paint is dry, you can apply a layer of medium to crack. As soon as it looks dry, use a second colour of contrasting acrylic paint. You will see the cracks appear after a few minutes.

  If you wish to, you can apply a protective varnish on the whole so that the second layer of acrylic is not damaged.

• For the Darwi 2-step cracking varnish (2 bottles of 100ml sold in a batch): if you want a background of colour to your cracks, paint your support with an acrylic paint. You can leave it as it is. When this first layer is dry, apply the varnish step 1. As soon as this varnish is dry to the touch, apply a second paint that contrasts with the first. Do not wait too long between applications, the reaction will not be as strong if you let rest for example 24h. Once again, wait until it dries to affix step two varnish. After 30 minutes, you will notice that the second layer of paint cracks and reveals the background colour.

You can also use this two-component varnish alone, without paint on all substrates including Cernit polymer clay. This will create an irregular and raised transparent layer that will look old. For even more relief, use Indian Ink or wax as a patina.

For these two products, it is possible to accelerate the drying without any risk of damaging the final result.

Once done, clean your tools with Darwi Cleaner Brush Cleaner or a degreaser such as alcohol, ethanol or methanol.
