The first thing you will do in this process is to put a satin enamel on the wall and allow for it to dry. After this, you will use chalk and a straightedge to measure out 4″ from both the baseboard and the chair rail. Mark this off,and put tape on the chalk lines.
Mix the smoky glaze that you are putting on well, and then put a good amount in a container. The first coat of this that you are going to put on will be thin, and this will be on the taped off panels. Then you will apply another thin coat to these so that they are even.
You will need to use a graining tool for this. You will put the top edge of the tool to the top edge of your tape as is shown in image 1. Then you will pull the tool straight down without stopping. Be sure that you rock it just slightly as you are pulling it down. This can take some practice, so be patient. Keep doing this until you have your desired wood grain effect in the panel you are working with as in image 2. Next you will do the other panels and then let it all dry.
Now is when you will take the tape off of the panels that you have done. Now, mix a little of the glaze with two acrylics that you have chosen. Use a scrap piece of molding for a guide, and lay it at the top of a panel. Using a fine artists brush, dip it in the paint and glaze mix, and make a thin line across the top of the panel as shown in image 1. This will give the appearance of depth. You line doesn’t necessarily have to be a solid one as in image 2. Repeat this process on one of the sides of the panel. The edges of the panel that are remaining will have the same thing done to them with only the black. Do not clean your brush between sides of the panel, or between colors. The darker color on the last two sides gives it better dimension. You can even draw thin lines between your makeshift planks of wood within the panel.
