This approach reduces drying time and helps prevent potential mold and mildew growth, ensuring that no dirt or cleaning products remain on the surfaces.
• Initiate 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 commence this vital process.
• Methodical Washing Approach
• 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 guarantee uniform coverage, and ensure to switch nozzles as necessary for 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. 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 prevent further complications.
• Allow Surfaces to Dry Between Passes
• After rinsing, let surfaces dry for approximately 15 to 20 minutes before tackling the next area. This step is crucial to avoid moisture becoming trapped beneath the surface, which can lead to warping or discoloration. Proper drying also helps deter mold and mildew growth.
• Application of Protective Coatings
• Once your deck or fence looks 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.
