Exterior areas are Pressure Washed
First we apply a combination of the following three cleaning agents to the desired surfaces:
- A salt based cleaning agent which removes mould and fungus along with killing mould spores, thereby retarding the return of green algae and black fungus.
- A grease cutting citrus solution which breaks down diesel fumes from buses/trucks along with road dust.
- An environmentally friendly neutral detergent which dissolves general dirt and grime.
We then wash off the same surfaces with medium to high pressure water: Pre-paint Cleaning or Pressure Washing. This process is the same as our standard exterior House Washing and Roof Washing services except we typically use higher pressure to remove as much flaky paint as possible/practical.
NOTE: High pressure cannot be used around timber door & window frames due to potential leakage, these areas are cleaned by hand with a soft brush and hose. A PRE-PAINT clean does not eliminate the need for scraping and sanding but assists with providing a clean, dust, algae and fungus free surface to work with.
