• Avoid the temptation to wash the entire yard or long sections of a 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 potential mold and mildew growth, ensuring that no dirt or cleaning chemicals remain on the surfaces.
• Start with a low-pressure pre-wash
• Before applying any detergents, rinse the entire surface with clean water to moisten the material and effectively loosen dirt. Utilize a wide fan nozzle set at approximately 40 degrees and a low spray pressure of 1100 PSI to initiate this crucial process.
• 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 be sure to switch nozzles as necessary for varying cleaning requirements.
• 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 observe any damage during the process, increase the distance accordingly to prevent further issues.
• Allow to dry between passes
• After rinsing, allow surfaces to dry for about 15 to 20 minutes before addressing the next area. This step is vital to prevent moisture from becoming 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 appears clean following the final rinse, allow it to dry completely for 24 to 48 hours before applying a protective sealer or stain. This waiting period ensures that any residual moisture evaporates, promoting better adhesion of the coating.
