MM26 Transparent Gesso has been specifically formulated to be mixed with the Matisse Background Colours to give a coloured primer with extra "tooth" for painting and especially as a pastel primer. Mix 1 part MM26 Transparent Gesso with 2 parts Matisse Background Colour (up to equal parts), stir well; the resultant mixture will give a brilliant surface on paper, board or canvas with which to accept and hold pastels including oil pastels.
(Hint: Vary the ratio of MM26 Transparent Gesso mixed with Matisse Background Colour to vary the degree of roughness or "tooth" in the primed surface.)
MM26 Transparent Gesso is similar to MM10 Gesso and MM25 Black Gesso only without pigmentation; therefore, giving a transparent (although not altogether clear) flexible primer for canvas, board or even paper with an excellent tooth for easy paint manipulation. If working on canvas, Matisse MM26 Transparent Gesso will tighten the canvas, making a firmer ground to paint on.
