6. Apply Two Coats of Stain
Put on your rubber gloves, open your four cans of stain, and brush on a coat of color using the diagram as your guide. Assemble all the panels that correspond to a particular finish and stain those at the same time. After one coat, the wood already looks glorious but it will take a second coat to give each panel a satin glow. Wait at least six hours for the first coat to dry completely. Then apply the second coat and wait another six hours for that coat dry. Obviously, you'll want to work in a ventilated garage or carport. Give yourself plenty of room to spread out, and be careful on those knees!
