Artis 2-step Crackle Varnish.

Twp-components varnish and different air dry times, which once applied onto the other, produce highly decorative cracks.
It can be used to crackle paper sheets, to add an antique look over any surface. Wood, furniture, walls, etc.

Instructions:
To obtain a good sized crackle, it is important to apply a considerable amount of the product on both steps of the process.
Apply two thick layers of product one. Air dry between application of layers.
Once the second layer of step 1 is mordent, apply only one layer of step 2. but very abundantly.
Tip: It would be best not to use the brush to stretch the product, rather than “lay it down” expanding it with our fingertips, trying to achieve a homogeneous and abundant layer.
The crackle is almost unnoticeable until it is highlighted with a brush wet with a little patina. The patina will strain into the crackles in order to highlight it. You can remove the excess with a cloth.
