Build your art on a strong foundation with Matisse Background Colours: an all-purpose pure acrylic that can be applied to almost any surface. Matisse 250ml Background Acrylics are a highly pigmented low-tooth gesso. Used directly onto wood, the Background Colour will not only cover and create a great surface to paint on but will also seal the surface with its built-in sealer. All Matisse 250ml Background Acrylics are specially designed for use on canvas (and board, etc.) however they have also been used extensively in interior domestic decoration.
