Merbau Leaching Stain Removal From Pavers Cost — At a Glance for AU
Merbau stain removal from pavers runs A$6.25–A$25 per square metre — the stain depth and the paver type carrying the range. This is a realistic planning number for Australia in 2026, not a marketing low-ball.
| Line Item | Typical Range (AUD) | What Drives It |
|---|---|---|
| Oxalic acid treatment per square metre | A$6.25–A$12 | The tannin stain at the chemical |
| Specialised paver cleaner | A$10–A$19 | The dedicated products at the marks |
| Sealed paver path | A$5.0–A$10 | The sealed surfaces at the easier removal |
| Unsealed paver path | A$12–A$25 | The porous surfaces at the deeper stain |
| Sealing after the removal | A$10–A$19 | The protection at the recurrence |
Understanding Merbau Leaching Stain Removal From Pavers Cost
The oxalic treatments at $5-$10 per square metre — the tannin stains at the chemical scope. The specialised cleaners at $8-$15 serving the stubborn marks. The sealed pavers at the easier $4-$8 path honestly.
The paver types at the depth: the sealed surfaces at the stain resistance — the removal at the easier band; the porous pavers at the absorbed tannins — the deeper scope at $10-$20 honestly. The sealing after the removal at $8-$15 protecting the recurrence — the prevention at the honest line.
What Moves the Price Up or Down
The price moves with the stain depth, the paver type, the chemical scope, and the prevention.
| Factor | Cost Impact | Detail |
|---|---|---|
| Stain depth and age | +25-45% | The set marks at the dwell |
| Paver type and porosity | +20-40% | The sealed against the porous |
| Chemical scope | +15-30% | The oxalic against the dedicated |
| Area size | -10-15% | The scale at the efficiency |
| Sealing scope | +15-25% | The prevention after the removal |
Paver Stain Removal Options
Two paths serve the marks — the chemical, the specialised trading.
| Option | Description | Best For | Cost Level |
|---|---|---|---|
| Oxalic acid path | The tannin chemistry at the removal | The standard marks | $5-$10 per m2 |
| Specialised cleaner path | The dedicated products at the stubborn | The set stains | $8-$15 per m2 |
| Removal and sealing path | The clean plus the protection | The recurrence risk | $13-$35 per m2 combined |
The oxalic serving the standard — the specialised serving the set at the honest scope.
Three Realistic Project Scenarios
The 20 m2 oxalic removal — A$120–A$250
A paved area at the standard tannin marks.
- Oxalic treatment — A$120–A$250
Why this matters: The oxalic path at the standard — the 20 m2 at the $150 total with the honest chemistry.
The 20 m2 porous paver removal — A$250–A$500
An unsealed area at the absorbed stains.
- Deep chemical scope — A$250–A$500
Why this matters: The porous path at the depth — the 20 m2 at the $300 total with the dwell time honestly.
The 20 m2 removal and sealing — A$320–A$880
The clean plus the protection scope.
- Removal — A$120–A$380
- Sealing — A$200–A$500
Why this matters: The combined path at the prevention — the 20 m2 at the $480 total with the recurrence protected.
The scenarios share the leach marks — the paver type and the prevention separating the totals.

From Quote to Completion: the Typical Timeline
Most merbau leaching stain removal from pavers cost projects follow the same five-stage rhythm. Knowing the calendar before you sign prevents the two classic frustrations — feeling rushed into a deposit, and being surprised by a mid-project gap while materials arrive.
- Cure and furniture return — 2-3 days
- Inspection and quote — 1 week
- Clean and prep — 1-2 days
- Coating application — 1-2 days
- Cure and furniture return — 2-3 days
Smart Ways to Control the Budget
Cost control on merbau leaching stain removal from pavers cost is mostly about scope discipline and timing. These are the strategies that consistently deliver the largest savings:
Bundle the rail and the deck at the same crew
The handrail sanding and reoiling at the $15-30 per lineal metre — the same crew, the same day, the single callout. The separate visits pricing the mobilisation twice honestly.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- The bundled scope at the one booking.
- Requires planning lead-time you may not have on urgent timelines
Oil before the grey, not after
The 12-18 month oiling cycle at the $4-8 per square metre keeping the timber hydrated — the grey weathering pricing the full $25-45 restoration instead of the maintenance coat. The calendar at the maintenance plan, not the damage stage.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- Requires the seasonal discipline at the reminder.
- Requires planning lead-time you may not have on urgent timelines
Price the prep before the coating
The clean, the sand, and the tannin treatment at the $8-15 per square metre before the first oil coat — the coating over the grime and the old stain pricing the peeling failure. The preparation quoted as its own scope.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- The prep line itemised before the coating quote.
- Requires planning lead-time you may not have on urgent timelines
Test the oil on an offcut first
The $60-120 test tin at the hidden board or the offcut — the merbau tannins and the prior coatings shifting the colour from the chart. The sample approved before the 20-litre commitment.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- Takes the patience at the colour decision.
- Requires planning lead-time you may not have on urgent timelines
Permits, Rules and Safety
No permit at the removal scope — the chemical outside the triggers. The runoff at the garden and the drain honestly.
- (‘Balustrade upgrade trigger’, ‘$0-500’, ‘The balustrade code at the 1-metre height line — the replacement rails meeting the current standard even at the repair scope.’, ‘The height verified at the repair quote.’)
- (‘No permit at the maintenance scope’, ‘$0’, ‘The like-for-like coating, the board swaps, and the sanding running outside the permit triggers — the structural changes always at the review scope.’, ‘The coating and the board replacement exempt at the structural-unchanged condition.’)
- (‘Balustrade upgrade trigger’, ‘$0-500’, ‘The balustrade code at the 1-metre height line — the replacement rails meeting the current standard even at the repair scope.’, ‘The height verified at the repair quote.’)
Maintenance and Long-Term Ownership Costs
The project price is only the first line of the budget. These recurring items are what owners in Australia actually spend money on after the crews leave:
| Task | Frequency | Typical Cost | Why It Matters |
|---|---|---|---|
| Coating inspection | 6-12 months | $0 | The water-beading test at the surface — the coating failure caught at the early stage, before the greying. |
| Gap cleaning | Quarterly | $0-100 | The debris cleared from the board gaps — the drainage and the airflow preserved at the routine. |
| Reoil cycle | 12-18 months | $4-8/sq m | The maintenance coat at the scheduled window — the full restoration avoided at the honest calendar. |
| Mould treatment | As needed | $50-200 | The shaded and the damp sections at the mould scope — the ventilation issue fixed at the cause, not the symptom. |
The sealed pavers at the easier future clean — the recurrence at the honest reduction. The deck at the first-coat timing serving the prevention.
