WOOD
RECOMMENDED EQUIPMENT:
-
Pressure Washer: 4 GPM or better, 2000 PSI or better
-
Pressure Washing Wand with 40 Degree Fan Tip
AVERAGE CLEANING RATE:
1200-1500 sq ft per hour
IMPORTANT NOTES:
All types of wood can easily be damaged with improper pressure washing technique or equipment. Relieve the pressure with the unloader to 1000-1500 PSI or use a larger orifice nozzle. Do not pull the trigger on the pressure washing wand while aimed at the surface. Instead, engage the trigger about knee level and bring the wand down in a sweeping motion. Continue in a even stroke for the entire plank of the wood. For the best results, pressure wash the wood as a preparation step for a restoration process.
RECOMMENDED SCOPE OF WORK:
Before beginning, ensure you have completed all the steps in the Worksite Preparation Guide.

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 wood.
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.

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.
