The pigments used in these paintings are applied to sheets of untreated or anodized aluminum (0.5 mm), copper or corten steel hung vertically on a rack connected to an electrical charge. The primal bounding agent for the pigment is electricity. Ultimately, the stabilizing agent is provided by heat.

The pigments are an assemblage of three or four different resins (polyester, epoxy, urethane, acrylic and sometimes a mix of epoxy-polyester). They are a super-fine powder, resembling talc, which become positively charged electrically as they are shot through a spray gun onto a negatively charged metal sheet. Colours cannot be mixed to make other colours, but can be added and baked, one on top of another to produce varying hues. Mat and glossy varnishes can also be used for visual effect. A final firing in an oversized, high-temperature oven cures the pigments on the metal surface, very much like an enamel finish.
