The short answer
If your concrete slab is structurally sound and you simply dislike how it looks, spray-on paving is the cheapest and fastest way to a paved appearance - days of work, no demolition. Pavers are the right answer when the base itself has failed, because the base gets rebuilt. Stamped concrete gives the deepest texture but requires a full new pour, so in Perth it costs and disrupts far more than an overlay.
Nearly every quote conversation we have starts with the same question: should I resurface, pave, or pour something new? The honest answer depends on the state of your slab and how long you plan to stay.
Below is the comparison as we would give it standing in your driveway, including the cases where spray paving is the wrong answer.
Key takeaways
- Sound slab, tired appearance: resurface.
- Rocking, heaving or undermined slab: pavers or replacement, not an overlay.
- Want genuine relief texture and happy to re-pour: stamped concrete.
- All three need sealing; only pavers need ongoing joint sand and weed control.
Spray-on paving (spraycrete)
A 2-3 mm polymer-modified cement overlay bonded to your existing slab, patterned and sealed. See spray-on paving for the full system.
It is the cheapest route to a paved appearance because there is no demolition, no spoil removal and no re-pour. Most domestic jobs are complete within a week.
- Strength: cost, speed, no excavation, follows existing drainage falls
- Weakness: needs a structurally sound slab; it is a surface, not a repair
- Maintenance: re-seal every three to five years in Perth sun
Brick and stone pavers
Individual units laid on a compacted base. The gold standard for repairability - you can lift and replace a single paver - and the only option that genuinely fixes a failed base, because the base gets rebuilt.
The trade-offs are cost, time and weeds. Excavation, base preparation and laying is labour-heavy, and joints need sand top-ups and weed management for the life of the surface.
- Strength: individually replaceable, base rebuilt, very long life
- Weakness: highest cost, longest disruption, joint weeds and settling
- Maintenance: re-sanding, weed control, occasional relevelling
Stamped concrete
A new slab poured and imprinted with texture mats while plastic. It gives real depth and relief because the pattern is in the concrete itself rather than on it.
But it is a new pour: demolition, cartage, formwork, curing. In Perth, it costs meaningfully more than an overlay and takes weeks rather than days.
- Strength: genuine texture depth, monolithic slab, long life
- Weakness: cost and disruption of full replacement, still needs sealing
- Maintenance: sealer renewal on a similar cycle to overlays
Which one for which situation
If your slab is sound and you dislike how it looks, resurfacing is almost always the right economic answer. If your slab is rocking, heaving or badly undermined, no overlay will save it and you should be pricing replacement or pavers.
If you are selling within a year or two, the overlay's presentation-per-dollar is very hard to beat. If this is a forever home with a failing base, spend once on the base.
A note on comparing quotes
Make sure quotes describe the same preparation. Two spray paving prices can differ by thousands purely because one includes proper grinding, crack chasing and degreasing and the other does not. Preparation is where longevity is bought - see our process.
Side by side, in Perth conditions
The differences that matter day to day are disruption, drainage and maintenance rather than headline price alone.
- Disruption: overlay days, stamped concrete weeks, pavers weeks including excavation and cartage
- Drainage: an overlay follows your existing falls; pavers and a new pour re-set them, for better or worse
- Weeds: only paver joints grow them
- Repairability: pavers win outright - a single unit can be lifted and replaced
- Sun: all three fade without sealer renewal on a Perth-facing driveway
Where spray paving is the wrong answer
We say no to overlay work more often than people expect. A slab that rocks under a car, has stepped cracking through a corner or is undermined by a burst service line is a structural problem. Coating it hides the symptom for a season, then the crack telegraphs straight through the new surface.
If that is your slab, get the base fixed first - see signs your driveway needs resurfacing for how to tell the difference between cosmetic and structural failure.
What we would recommend by situation
- Selling within two years: overlay, for presentation per dollar
- Forever home with a failed base: rebuild the base, then pave or pour
- Commercial or civil traffic: StreetBond over sound concrete
- Garage or interior floor: epoxy, not an exterior paving system
Frequently asked questions
- Is spray-on paving cheaper than pavers in Perth?
- Consistently, yes, because there is no excavation, base work, cartage or spoil disposal. The saving is largest on big flat areas like double driveways.
- Does spray paving last as long as pavers?
- A well-prepared overlay that is re-sealed on schedule lasts many years, but pavers on a properly built base will outlive it. The trade is longevity against cost, speed and disruption.
- Can spray paving be applied over stamped concrete?
- Usually yes, if the stamped surface is sound and the old sealer is mechanically removed. Deep relief patterns will still read faintly through a thin overlay.
- Which option adds the most value before selling?
- For presentation per dollar within a short timeframe, resurfacing is very hard to beat - the frontage changes completely in under a week.
