Why this matters for Melbourne properties
This Brick Cleaning article is written for Melbourne owners and managers who need more than a quick blast. Brick 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.
Render is paint-coated
Most modern render finishes are sealed with acrylic. Acid attacks the binder and dulls colour permanently. Soft wash is mandatory.
Raw brick wants different chemistry
Mineral surfaces tolerate dilute acid well. Acrylic surfaces do not. Always identify the substrate first.
Mixed walls need zoned cleaning
Many homes mix render at the base with brick above. Each zone gets its own treatment plan.
