Art Spectrum® Colourfix™ Primer is a fine tooth, quick drying acrylic primer which bonds aggressively to practically any clean, dry surface – all types of papers (300 gsm or heavier recommended), canvas, card, ply, plastic, glass, timber, ceramic and metal. Art Spectrum® Colourfix™ Primer can be applied with brushes, sponges, rollers etc. straight from the pot. 20 colours are available, including Clear*. All colours can be intermixed, or tinted with Art Spectrum Inks or Gouache, to create new shades. The Clear Colourfix™ Primer allows the natural surface or underlying colours to remain visible, whilst providing extra tooth for more overlays. Use Clear and other Art Spectrum® Colourfix™ Primers for mixed media techniques and experimental art and craft works. It can even be used as an adhesive for collage.
