This strategy minimizes drying time and helps prevent the growth of mold and mildew, ensuring that no dirt or cleaning agents remain on the surfaces.
• Start with a low-pressure pre-wash
• Before applying any detergents, rinse the entire surface with clean water to saturate the material and loosen dirt effectively. Use a wide fan nozzle set at approximately 40 degrees and a low spray pressure of 1100 PSI to begin this vital 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 remember to switch nozzles as needed for varying cleaning requirements.
• Maintain the correct distance
• For optimal cleaning results, it is essential to keep the right distance between the nozzle and the surface. Generally, a distance of 6 to 12 inches (15 to 30 cm) is recommended for the best performance. If you notice any damage during the process, increase the distance accordingly to avoid further issues.
• Allow to dry between passes
• After rinsing, let surfaces dry for about 15 to 20 minutes before moving on to the next area. This step is critical 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 is 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 is essential to ensure any residual moisture evaporates, promoting better adhesion of the coating.
