Sand the entire piece of furniture with 180-grit sandpaper until the wood is completely smooth.
Clean the dust left by the sandpaper off with a tack cloth. Leaving dust on the surface of wood will result in a poor quality finish.
Prime the furniture piece with an even coat of alkyd primer using a paintbrush. Allow the primer to dry for 24 hours.
Sand the alkyd primer coat lightly with 180-grit sandpaper. Always sand with the grain of the wood. Sand lightly to avoid sanding through the primer.
Brush an even coat of top coat exterior grade paint with a paintbrush. Paint in the same direction as the wood grain. Apply a second coat if desired. Allow four hours between coats.
