Perfetto Crackle Products
Perfetto's crackle products are all acrylic water-based crackle mediums that may be tinted or color washed to achieve the desired color. Perfetto crackle products are designed to be used over Perfetto Crackle Size. The Crackle Size is applied first by brush, spray or rolling, allowed to dry for at least one hour (more or less depending on conditions), then one of the crackle products may be applied over the top. As with all Perfetto crackle products, applying the size fairly thick will help with the crackle process, resulting in larger cracks as thinning the Crackle Size with water and applying a thinner coat will tend to yield small cracks. The four primary factors that affect the size of the cracks on all Perfetto crackle products are...
1) the thickness of the Crackle Size
2) the thickness of the coat of Crackle product applied
3) the drying conditions
4) the direction the Crackle product is applied
Applying an average coat of Crackle Size, allowing it to dry and them putting on a very thick coat of the crackle in an environment of warm circulating are will provide large obvious cracks. If brushed, the crackle products tend to crack more in the linier direction of the brush stroke. It is for this reason that we often recommend stippling or pouncing the crackle on in a very thick manner.
It is strongly recommended that numerous samples be created before going "live" with these products, to guarantee the results you are looking for.
