Spray, wait, brush, and rinse. No, it's not tooth brushing--it's one-day deck restoration using three water-based products to wash, brighten and seal without drying time between these steps. Apply each product in a separate pass: spray in consistent sweeps to wet the surface, let stand, scrub with a synthetic-bristle brush, rinse, and apply the next product.
Pour two quarts of warm water into the deck sprayer and add the cleaner concentrate. Stir thoroughly with a piece of wood before assembling and pumping up the sprayer. Be sure to wear protective covering on your eyes and hands.
Spray cleaner in consistent strokes with the nozzle a foot from the surface. Thoroughly wet a 20 to 30 square foot area without pooling the liquid. Let the cleaner soak on the deck for about 10 minutes.
Work with the wood grain and scrub the treated area with a synthetic-bristled brush. Apply gentle pressure to agitate the solution and work it into the deck surface and lift embedded grime.
Equip your hose with a high-pressure nozzle and hose the cleaning solution from the deck. If you are working on grass or near plants, wet them to help dilute the solution before it touches them.
Mix the brightener the same way as the cleaner, adding water and solution and then stirring. Brightener blends the color tones. Using brightener is somewhat optional, but wearing protective covering over eyes and hands is not.
Spray brightener on the damp cleaned deck with consistent overlapping strokes. No drying time is required on the deck restoration before applying the brightener.
Let the brightener stand on the cleaned deck surface for about 10 minutes. Set the hose nozzle to mist and dampen with water. Lightly scrub with the synthetic-bristle brush and then rinse with the hose nozzle set to high pressure.
Use a large paint applicator pad on a long handle to weather-proof the cleaned and brightened deck boards with the sealer/stain product. Run the pad with the wood grain to fill crevices and coat the planks evenly.
