Two colors of basecoat are needed for the wood-grain look—a dark, reddish brown (T442 Woody Brown at 800.0 pts. and T430 Green 100.0 pts.) and a lighter tan color (T429 Trans. Golden Yellow at 940.0 pts., T442 Brown 40.0 pts. and T430 Green 20.0 pts.) In my case, Hutton uses PPG Envirobase® High Performance basecoat and he says it works wonderfully.
“I especially like the fact that if you apply some paint and you don’t like the effect you’re getting, you can easily re-wet again with more waterborne color, giving yourself a fresh start,” said Hutton.
Painting the Outer Frame
(1) Hutton starts with a white base-coated panel, masked off to create a center panel. Each end of the outer frame should be masked with mitered corners, typical of wood frames.
(2) Start with the top and bottom portions of the frame. Wet your finer sponge with the lighter tan color, squeezing out the excess by pressing it into the side of the mixing cup. Then, simply drag the sponge across the surface in one direction, repeating the process several times. Next, we need to mask the outer frame to create a beveled look. With ¼-inch tape, mask from the side where you want the light source to appear to come from. Do the same with the bottom edge. Then mask the frame panels, leaving only the bottom edges of the frame exposed.
(3) Then, as the paint begins to dry and get sticky, drag your gloved hand across the painted surface. As it begins to drag it’ll create authentic-looking grain with that knotty look. After dragging all the way across the panel for several strokes, start from the center and drag, and make smaller swipes in succession, gradually tapering your strokes to short swipes. If the paint starts to set, just re-wet it with more waterborne paint.
(4) After finishing the top and bottom of the outer frame, mask the corners off before doing the sides. Be sure to “under mask” a bit, which in the end will create a darker line highlight. Then, using your sponge and gloved hand, create the wood-grain look on the side panels, as you did on the top and bottom. Remove the masking on the corners and allow the paint to dry.
(5) Next, we need to mask the outer frame to create a beveled look. With ¼-inch tape, mask from the side where you want the light source to appear to come from. Do the same with the bottom edge. Then mask the frame panels, leaving only the bottom edges of the frame exposed.
(7) Airbrush the areas left unmasked. This will darken them and create the illusion of shadows.
(8) After creating the darker shadow lines, re-mask over the lines in preparation of creating a lighter, highlight line. Once you airbrush the unmasked areas of the frame, making it darker, the area covered by the tape will leave a lighter, highlight line.
(10) Shadow and Toning. Next, reduce the same lighter color with a clear basecoat T490 at 2:1, and reduce 4:1 with reducer. This will make the color more transparent. Airbrush the outer frame panels to add tone and accentuate the grain in the wood. When the ¼-inch lines are unmasked it will leave the lighter highlights.
Painting the Center Panel
(11) After it’s dried, re-mask the outer frame, and remove the masking from the center—you’re ready to create the wood grain effect on the middle panel. With the sponge, use the same technique as the outer frame to apply the color. Start at one end and drag the sponge in straight lines across the panel. Keep applying coats and as the paint begins to dry, it’ll get sticky and cause the sponge to drag. This creates a streaked, grained look.
(12) Now you want to add tone with a paintbrush and the darker, reddish shade of brown. Dip the brush into the mixing cup and tool it out, so little is left on the bristles. Using light strokes, swipe the brush across the panel, creating the darker streaks. First, apply strokes horizontally across the panel. Be sure to leave streaks to mirror the inconsistent color of natural wood.
(13) Next, airbrush the panel in vertical, up ‘n down strokes. This is called “ribbing.”
(14) If you’d like to add a simple logo, this is the stage to do it. Using the same paint you used to tone the wood, airbrush the cut-out of the logo. This will create a darker highlight around the letters, creating a de-bossed effect.
