Apply one coat of water repellent to the cedar wood. Dip a brush or roller into the water repellent solution and spread over the cedar. Allow the water repellent to dry completely before applying the primer.
Apply a stain-block primer to the cedar. Brush onto the wood, covering the entire area. The primer provides a foundation for the paint. Allow the primer to dry before painting the wood.
Pour the paint into a paint pan and apply to a paint brush or roller. Paint the cedar, covering all the wood with paint. Allow the paint to dry and then determine if you need a second coat. Apply a second coat only after the first coat has dried properly.
