This Restoration article is written for Melbourne owners and managers who need more than a quick blast. Concrete & Paver 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.
Sandstone hates pressure
Even moderate pressure pits the surface and accelerates erosion.
Poultice draws out stain
Inert clay + appropriate solvent absorbed into the stone, drying as it pulls staining up.
Multiple cycles common
Older stains may require 2–4 poultice applications — patience pays.
On the job
- Understand why sandstone hates pressure matters before you choose a cleaner.
- Understand why poultice draws out stain matters before you choose a cleaner.
- Understand why multiple cycles common matters before you choose a cleaner.
