Golden Fluid Matte Medium is a liquid, pourable acrylic medium useful for extending colours, increasing translucency and decreasing gloss. It is also useful as a translucent ground. To lower the sheen of a paint colour or another medium, begin by adding Fluid Matte Medium in increments of about 10% of the total volume. It is helpful to brush out each mixture, and let dry on a piece of paper to note the difference in sheen. With some experimenting, it will become easier to know how much of the matte medium is required to achieve the desired gloss.
Fluid Matte Medium can be used as a translucent ground, sometimes referred to as a "clear" gesso. It is thin enough to penetrate canvas and other porous substrates easily, and the matting solids provide an adequate "tooth" for additional paint layers. In thin applications it can appear quite translucent, while darkening the canvas to a small degree. The darkening effect, similar to a "wet look”, is somewhat more pronounced with Fluid Matte Medium.
Apply Fluid Matte Medium in much the same manner as recommended for the application of a gesso layer. Apply one or more coats, keeping in mind that additional layers will gradually make a more opaque overall film.
