Wash away any surface dirt from the lumber by scrubbing it with a mild detergent.
Mix the wood brightener product with water according to the manufacturer's directions if it is concentrated.
Spray the wood brightener onto the lumber using a garden sprayer. Allow it to sit for 15 to 20 minutes and then rinse it off with a hose.
Lay out the wood to dry in warm, sunny weather for 2 to 3 days.
Brush paint onto the individual boards. Coat the entire length of each board with each stroke in order to prevent lap marks.
Allow the first coat to dry according to the paint manufacturer's directions before applying a second coat.
Brush on a second coat of paint to eliminate the green show-through that can occur with treated wood and to give the wood an even appearance.

- Brushing is considered to be the optimal application technique. However, using a paint sprayer is a quick and easy alternative that is another option.
- Paint is not recommended for horizontal surfaces that will receive heavy traffic or weathering. Paint has a tendency to peel and mar under these circumstances. Stain would be a more appropriate choice.
- If the wood is still wet from being treated, allow it to air dry no longer than 2 to 3 weeks.
