- Apply a light gray base coat to your surface and let it dry. Mix a glaze in a darker shade of gray, one part paint to four parts glaze. Paint the glaze onto the surface in an uneven fashion, covering all areas, but leaving some areas with a heavier layer of glaze. Apply the glaze in 3-foot square sections. Lay a sheet of plastic on the wet glaze and pull up some spots of the plastic slightly. Twist the plastic around a bit, then pull it off the surface entirely. This will leave behind lines and veins. Allow this to dry, then take a feather and dip it into white paint, then dip it into a bit of black paint. Pull the feather very gently along the lighter areas left behind.by the plastic folds to create the thin lines of veined marble.
- Start with a base coat in a beige color. Paint it on and let it dry. Make a glaze in a darker color, made of one part brown paint and four parts clear glaze. Apply this to the surface with a sponging technique, blotting it on, so the surface looks uneven yet covered. Let this dry. Apply another glaze in another shade darker than the first glaze. Apply it more sparsely than the first glaze and let it dry. Dip a feather into white paint and pull it across the surface of the dried glaze in varying lengths, widths and directions to make realistic looking veins.
- Apply two coats of eggshell white paint, allowing the first coat to dry for four hours before applying the second coat. Prepare a glaze mixture of one part gold-tone paint with four parts glaze. With a small paint brush, stipple (dabbing it on) this glaze onto the white paint in random sections. Allow it to dry. Repeat this process with a smaller brush, stippling on a darker colored gold-tone glaze in areas not covered by the first glaze. This process should leave a mottled look. Now brush over the colored areas with a soft paint brush to smooth out the look. Dip a dagger paint brush (available at art supply stores) into the darker shade of gold paint and dip it again into a bit of brown paint. Dab it lightly into the colored areas to create irregular marks and veining that's natural to marble.
