Plastics are a highly present material in our lives. Opaque, colourful or transparent, porous or smooth, they are easily accessible personalisable surfaces.
There is no particular preparation to be done on plastics but on some of them, the more porous ones, POSCA PASTEL will adhere more and in a more durable way. The smooth wax material will remain on the surface with relative ease.
The transparency of the plastic may be an advantage for certain creations and POSCA PASTEL may also be combined with other techniques.
On uneven surfaces, the adhesion is good but on other, smoother surfaces protection is needed. A layer of acrylic binder, which can be applied with a paint brush, will act as a protective film.
Without protection, POSCA PASTEL will always be exposed to friction and may, if pressing hard, be removed with a cloth.
