Detailed Instructions for Safe and Effective Pressure Washing of Wood Decks

Once you have all necessary cleaning products and equipment ready, it's time to thoughtfully prepare your work area:

• Work in manageable sections
• Resist the urge to wash the entire yard or lengthy sections of fence at once. Instead, divide the area into smaller, more manageable sections for thorough cleaning from top to bottom. This method reduces drying time and helps prevent the growth of mold and mildew, ensuring that no dirt or cleaning chemicals linger on the surfaces.
• Initiate with a low-pressure pre-wash
• Prior to applying any detergents, rinse the entire surface with clean water to moisten the material and effectively loosen dirt. Use a wide fan nozzle set to approximately 40 degrees and a low spray pressure of 1100 PSI to kick off this vital process.
• Conduct Methodical Washing
• Make consistent up-and-down passes over each section using an appropriate nozzle angle while gradually increasing the pressure to between 1000 and 2500 PSI, depending on the surface type and level of soiling. Overlap each strip by a few inches to ensure uniform coverage, and switch nozzles as necessary for varying cleaning needs.
• Maintain the correct distance
• For optimal cleaning results, it’s crucial to maintain the appropriate distance between the nozzle and the surface. Generally, a distance of 6 to 12 inches (15 to 30 cm) provides the best performance. If you notice any damage during the process, increase the distance accordingly to avoid causing further issues.
• Allow surfaces to dry between passes
• After rinsing, allow surfaces to dry for about 15 to 20 minutes before tackling the next area. This step is vital to prevent moisture from being trapped beneath the surface, which can lead to warping or discoloration. Proper drying also helps inhibit mold and mildew growth.
• Applying protective coatings
• Once your deck or fence looks clean after the final rinse, let it dry completely for 24 to 48 hours before applying a protective sealer or stain. This waiting period allows any residual moisture to evaporate, promoting better adhesion of the coating.
