This method reduces drying time and minimizes the chances of mold and mildew growth, ensuring that no dirt or cleaning products linger on the surfaces.
• Start with a low-pressure pre-wash
• Before applying any detergents, rinse the entire surface with clean water to dampen the material and effectively loosen dirt. Use 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 to meet varying cleaning requirements.
• Maintain the correct distance
• For optimal cleaning results, it’s essential to keep the proper distance between the nozzle and the surface. Typically, a distance of 6 to 12 inches (15 to 30 cm) yields the best performance. If any damage is observed during the process, increase the distance accordingly to prevent further issues.
• Allow for drying between passes
• After rinsing, allow surfaces to dry for approximately 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 deter mold and mildew growth.
• Apply protective coatings
• Once your deck or fence appears clean after 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.
