Melbourne & Victoria
Commercial-grade pressure washing for hard surfaces across Melbourne — from a single driveway to a multi-level car park. We match pressure and technique to the substrate, because the fastest way to ruin concrete, pavers or render is to hit it with everything the machine has.
Drawn to specification — site photography scheduled. Not presented as a Vastex job.
02 — The method
We confirm what the surface actually is — sealed or unsealed, decorative or structural — and set a maximum safe pressure for it.
Organic growth and oil are chemically pre-treated and given dwell time. This is what stops the stain returning in six weeks.
Adjacent surfaces, garden beds and drains are protected. Water capture is set up where required.
Surface cleaner on flat areas, detail wand on edges and corners, soft wash on anything that cannot take pressure.
A full rinse, jointing sand topped up on paved areas where needed, and the site left clear.
01 — The detail
A 4000 PSI machine will strip the cement paste off a concrete slab and leave the aggregate exposed in permanent stripes. It will blow the jointing sand out of a paved area and carve visible lines into softwood decking. The equipment matters far less than knowing what to set it to.
We work from the substrate backwards. Sealed and decorative concrete gets low pressure and a wider fan. Bare structural concrete can take considerably more. Render, painted surfaces and soft timber get soft washing — low pressure with the right detergent doing the actual work. Oil and grease on a workshop floor gets hot water, because cold water simply moves it around.
Open wand work on a big slab always leaves wand marks — overlapping arcs that show up the moment the surface dries. On any substantial area we use a rotary surface cleaner, which holds a fixed distance and overlaps evenly, so a 300 square metre car park dries as one consistent tone instead of a herringbone of stripes.
Different contaminants need different chemistry. Blasting everything with plain water is why so many DIY jobs look worse a month later.
On commercial and construction sites, where the water goes is part of the job. We use biodegradable detergents, and where the site requires it we set up containment and capture so wash water is not going straight into a stormwater pit. If your site has an environmental management plan, send it through with the enquiry and we will work to it.
03 — Pressure Washing FAQ
Whatever the surface can safely take — typically 1200–1500 PSI on render and painted surfaces, 2000–2500 PSI on pavers and decorative concrete, and up to 3500+ PSI on bare structural concrete and heavy industrial floors. Anyone quoting you a single number for every job is not thinking about your surface.
Not at the correct pressure with the correct technique. The two common failures are stripping the surface paste off decorative concrete and blowing jointing sand out of paved areas. We work under the safe threshold for the substrate and re-sand joints where the job calls for it.
We carry our own equipment and can run off site supply or bring water where none is available — just flag it when you enquire so it is priced in rather than sprung on you on the day.
Most Melbourne driveways and paths benefit from a clean every 12–24 months. Shaded, south-facing and tree-covered areas grow mould faster and are usually annual. Commercial frontages and food-service areas are typically quarterly or six-monthly.
