This method reduces drying time and helps prevent potential mold and mildew growth, ensuring that no dirt or cleaning chemicals linger on the surfaces.
• Start with a low-pressure pre-wash
• Prior to applying any detergents, rinse the entire surface with clean water to wet the material and loosen dirt effectively. Utilize a wide fan nozzle set at approximately 40 degrees and a low spray pressure of 1100 PSI to initiate this important process.
• Methodical Washing
• Make consistent up and down passes over each section using an appropriate nozzle angle, gradually increasing the pressure intensity to between 1000 and 2500 PSI based on the surface type and level of soiling. Overlap each strip by a few inches to ensure uniform coverage, and be sure to change nozzles as necessary for varying cleaning requirements.
• Maintain the correct distance
• For optimal cleaning results, it’s essential to maintain the correct distance between the nozzle and the surface. Typically, 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 prevent further issues.
• Allow to dry between passes
• After rinsing, allow surfaces to dry for approximately 15 to 20 minutes before moving on to the next area. This step is crucial 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.
