Pigment Stick Supports
The term “support” refers to the foundation, or backing, on which the actual painting surface (ground) is applied. Pigment Sticks® can be used on any ground suitable for use with traditional tube oil paint. Normally that means a sized canvas, panel, or paper. Ampersand’s Gessobord™ is ideal because of its dimensional stability. More absorbent surfaces like clay coated papers or Encausticbord™ will cause the paint to dry faster and leave a matte finish that is preferable to some painters. When thoroughly dry, Pigment Sticks® can be varnished just as you would an oil painting.
Sizing: As in oil painting, all canvas and paper surfaces should be sized. To size, use one or two coats of acrylic gesso, acrylic medium, or PVA sizing. Other options include: rabbit skin glue and shellac.
Grounds: Any ground (ie: gesso) suitable for traditional oil paint can be used with R&F Pigment Sticks®.
Recommended supports for Pigment Sticks include: stretched canvas; paper; clay-coated paper; clayboard; Encausticbord; lauan, plywood, or masonite panels; copper, iron, or aluminum; glass; and plexiglas.
