Pre-Paint Cleaning


Exterior walls being primed for painting are Pressure WashedFirst, we apply a combination of the following three cleaning products to the desired surfaces:

  1. A salt-based cleaning agent that removes mould and fungi, killing mould spores and thereby retarding the return of green algae and black fungi.
  2. A grease-cutting citrus solution thatbreaks down diesel fumes from nearby traffic, road dust, and BBQ splatter.
  3. An environmentally friendly neutral detergent thatdissolves general dirt and grime.

After applying the three cleaning agents, we wash off the same surfaces with medium- to high-pressure water—known as a Pressure Wash. All exterior glass is flushed off with fresh water to remove residue. Note, however, that this glass flush-down is not a proper window cleaning (see: Window Cleaning Services).

Older timber window and door frames (joinery typically found on villas and bungalos) have a tendency to leak even when soft washed, so we hand clean around timber joinery with a soft brush and hose. Just to make certain to avoid any water egress, we do recommend you put old towels down on the inside sills to minimise potential leakage. This is not necessary for aluminium joinery.

This process is similar to our standard exterior House and Roof Washing service, with the main difference being that we typically use higher pressure water to remove as much flaky paint as possible or practical.


NOTE: High pressure water cannot be used around timber door and 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 in providing a clean, dust-, algae-, and fungi-free surface to work with.
