Acrylic paint adheres to all possible grounds such as paper, cardboard, universally prepared artists' canvas and canvas board, unprepared artists' canvas, stone, wood, concrete and unglazed ceramics. Prerequisite for good adhesion is a surface free of grease and dust and slightly absorbent. For good adhesion preparation is not necessary, but of course possible. Amsterdam Gesso transparent, white or black is a good ground for Amsterdam acrylics.
