The desired design is cut out of the selected medium and then the image is transferred to a surface through the use of spray paint or roll-on paint.
Aerosol paint needs different types of plastic-like polymers to make it work. The most commonly used are alkyds and acrylics. Polyvinyl acetate (PVA) is another substitute for acrylics. Different companies will use specific mixes of polymers and plasticizers (like dibutyl phthalate and dibutyl meleate) to make the spray paint flexible and ...
Polyvinyl acetate is also the raw material to make other polymers like: Polyvinyl alcohol −[HOCHCH 2 ]−: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules .
Stencil technique in visual art is also referred to as pochoir. A related technique (which has found applicability in some surrealist compositions) is aerography, in which spray-painting is done around a three-dimensional object to create a negative of the object instead of a positive of a stencil design. This technique was used in cave ...
