Why this matters for Melbourne properties
This Restoration article is written for Melbourne owners and managers who need more than a quick blast. Render Cleaning jobs in our city require a surface diagnosis before any cleaning starts.
In Melbourne, everything from growth corridor new-build mortar smear to inner-suburb heritage brick has its own cleaning risk profile. The right method, chemistry and pressure keep the surface safe and the result lasting.
Soft wash is essential
Painted render flakes under high pressure. Soft wash uses chemistry alone.
Biocide dwell time
15–30 minutes contact time for full mould kill — rushing makes it return faster.
Final rinse low pressure
Maximum 500 PSI rinse — anything more risks paint adhesion.
