COMPOSITE (TREX OR IPE)

RECOMMENDED EQUIPMENT:

• Pressure Washer: 4 GPM or better, 2000 PSI or better

• Pressure Washing Wand with 40 Degree Fan Tip and Turbo Nozzle

AVERAGE CLEANING RATE:

1000-1500 sq ft per hour

RECOMMENDED SCOPE OF WORK:

Before beginning, ensure you have completed all the steps in the Worksite Preparation Guide.

1. PRETREAT & SCRUB

   Use a downstream injector to apply a generous amount of 1% soft wash solution. This will help kill organics and provide the soap needed to clean composite properly. Use a soft bristle brush to scrub each plank and agitate the surfactant. Allow 10 minutes of dwell time before proceeding.

2. CLEAN EDGES

   Use a 40 Degree Nozzle (White or the high pressure fan tip in the Jrod configuration) to pressure wash the edges of the concrete.
   
   If you are pressure washing concrete next to landscape, stand on the landscaping and aim the wand into the siding of the concrete. This will prevent the nozzle from blasting the landscaping and minimize damage.
   
   Move the nozzle in a slow and controlled straight line along the concrete about 4-6 inches away from the surface in a single pass. Continue this until the entire outline of the surface is complete

3. RINSE & INSPECT

   Once the entire surface has been cleaned, it's time to rinse. Use partially open ball valve or a M5 Nozzle to rinse the entire concrete clean. Inspect the concrete for any missed spots, post cleaning damage, or any other defects. Use the pressure washing want to touch up these spots or reapply the surface cleaner to larger areas.
