Learn to paint in Acrylic paints - Step by Step
Think I noted previously that I like playing with shapes and textures; this comes from my photography background. One product that I find quite fascinating is Golden Crackle Paste. This is a gel product formulated with acrylic and polystyrene in order to produce an emulsion failure upon drying. The result is a quite variable degree of film cracking, depending upon the film thickness and, to some degree, the mode of application. The key word is variable, as it is next to impossible to achieve predictable results from one application to another.
The "Autumn Leaves" photo is a 5 x 7 piece of acid free Foamcore, which was sealed and primed prior to application. There is some central buckling of the substrate even with this small size - rigid substrates are recommended due to the physical properties of crackle paste and the stresses produced as it dries. This piece was done as an exercise, just to get a feel for different techniques. Due to the highly textured surface, glare is evident in the photo. A polarizing filter might help, but it would also affect the contrast and colour saturation.
Crackle paste does have a tendency to curl at the edges and flakes can completely lift from the substrate, so sealing with diluted Soft Gel Gloss is suggested prior to painting. This also helps control the overall staining so the fissures can be highlighted.
The other two images show a 9 x 12 panel with the bare crackle paste, and after sealing with SGG and stained with fluid acrylics. Not sure where this panel will be going, but there are several possibilities. As the results are so variable, I find it best to play things out rather than try control the process too much.
Another 9 x 12 panel is about half done, and will be shared when completed. These were worked on last week; the first time I have gotten my hands dirty in over a year. Felt good!!
