After the back of the panel is cured, remove the old tape and add new tape to the bottom edge for easy epoxy drip removal at the end of the project. Mix a small amount of brown paint with a large amount of white paint to create a light, sandy brown color. Once the desired color is achieved, mix in a bit of fluid pouring medium to extend the working time of the paint and help soften the brush strokes. Brush on two layers of your light brown to the left side of your panel. Make sure that all exposed wood is covered, including the sides of the panel. When dry, use a white acrylic gesso to prime the entire right side of the panel, making sure all exposed wood is painted. Let the base layer dry completely before moving on to the next step.
