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. All colours are available in 250ml pots. Black, White and Clear are also available in 1 litre tubs.
