Pool resurfacing is one of the most significant maintenance investments a Melbourne pool owner will make — and one of the least understood. Most people know their pool needs it eventually, but few know what the process actually involves, how long it takes, what it costs, or what the pool will look and feel like on the other side.
This guide covers the complete process from start to finish, so you know exactly what to expect before, during, and after your pool is resurfaced.
Why Pools Need Resurfacing?
Pool surfaces don’t last forever. Depending on the surface type, water chemistry, usage, and maintenance history, most pool surfaces need resurfacing every 10 to 20 years. The most common signs that resurfacing is due include:
- Rough or abrasive surfaces that scratch swimmers’ feet and damage swimwear
- Visible staining that can’t be removed through cleaning or chemical treatment
- Plaster pitting or pockmarking — small craters in the surface caused by low pH water or calcium deposits
- Crazing or spider cracking — a network of fine cracks across the surface
- Delamination — sections of the surface peeling or lifting away from the shell
- Persistent algae problems despite correct chemical maintenance, often caused by porous or deteriorating surface material
If you’re noticing any of these, pool resurfacing in Melbourne is likely overdue. Delaying once the surface has genuinely deteriorated tends to make the underlying problems worse and the eventual job more expensive.
Step 1: Initial Assessment and Surface Selection
The process begins with a professional assessment of your pool’s current condition. A technician will inspect the existing surface, the pool shell, any visible structural issues, and the coping around the pool edge.
This assessment determines whether resurfacing alone is sufficient, or whether additional work is needed before resurfacing can proceed — such as crack repairs to the shell, coping repairs or replacement, or tile repairs along the waterline.
The other key decision at this stage is surface selection. The main resurfacing options for Melbourne pools are:
Pebblecrete / Exposed aggregate — the most popular choice in Melbourne. Small stones or pebbles are set into the plaster, creating a textured finish that’s durable, slip-resistant, and available in a wide range of colours and aggregate sizes. Lifespan of 15–20+ years with proper maintenance.
Marble plaster / White plaster — the traditional pool finish. Smooth, relatively economical, and attractive when new. More prone to staining and etching over time than aggregate finishes, with a typical lifespan of 10–15 years.
Quartz plaster — plaster blended with quartz aggregate for improved durability and stain resistance compared to standard marble plaster. A good mid-range option.
Fibreglass resurfacing — applying a fibreglass gelcoat over a concrete shell. Smooth, non-porous surface that resists algae and is easy to clean. Increasingly popular as a renovation option.
Ceramic or glass tiles — the premium option. Exceptional durability, ease of cleaning, and aesthetic impact. Significantly higher cost and installation time than plaster or aggregate finishes.
Your choice will depend on budget, aesthetic preference, and how long you intend to stay in the property. A good resurfacing contractor will walk you through the options and provide samples to assess in your actual outdoor environment before committing.
Step 2: Draining the Pool
Once surface selection is confirmed and the job is scheduled, the first physical step is draining the pool completely. This is not a quick process — a standard residential pool takes several hours to drain fully, and the water needs to be directed to an appropriate drainage point in compliance with local water authority requirements.
Melbourne’s climate is relevant here. Pool shells are designed to hold water — the weight of the water counteracts hydrostatic pressure from groundwater beneath the pool. Draining a pool during or after heavy rainfall can, in some soil conditions, cause the pool shell to lift or move. Your contractor should assess timing appropriately and may need to monitor conditions during the drain.
Professional pool draining in Melbourne as part of a resurfacing job is handled carefully to ensure the shell isn’t compromised before work begins.
Step 3: Preparing the Existing Surface
This is the most labour-intensive part of the process, and the quality of preparation is the single biggest determinant of how long the new surface will last.
Preparation typically involves:
Acid washing or pressure washing — cleaning the existing surface and removing scale, algae residue, and mineral deposits to give the new surface a clean substrate to bond to.
Mechanical preparation — grinding, chipping, or sandblasting the existing surface to create the texture and profile the new finish needs to adhere properly. With older plaster pools, the deteriorated plaster is often partially or fully removed back to the concrete shell.
Crack and structural repair — any cracks in the shell are filled and repaired at this stage. Ignoring cracks before resurfacing simply means the cracks will reappear through the new surface over time.
Inspection and approval — a competent resurfacing contractor won’t proceed to application until the prepared surface passes inspection. Rushing or skimping on preparation is the leading cause of premature resurfacing failure.
Step 4: Applying the New Surface
With preparation complete, the new surface is applied. The method and duration vary depending on the surface type chosen.
Plaster and aggregate finishes are applied by hand, trowelled onto the pool shell in a process that requires skilled tradespeople working efficiently together. The entire pool surface is typically applied in a single continuous session — stopping and restarting creates visible join lines. For a standard residential pool, the application takes a full day with an experienced crew.
The surface is worked progressively from the top of the walls down to the floor, with particular attention to corners, steps, and the junction between the walls and floor, where quality finishes most obviously differentiate experienced from inexperienced applicators.
Fibreglass coatings are applied by spray or roller in multiple layers, with curing time between coats.
Tiling is the most time-consuming option, with each tile set individually and grout applied after the adhesive has cured.
Step 5: Curing — The Critical Period Most People Underestimate
This is the stage that surprises most pool owners. After application, a plaster or aggregate surface needs to cure properly before the pool is filled and used. Rushing this stage is one of the most common causes of premature surface failure.
For plaster and pebblecrete finishes, the immediate post-application period involves keeping the surface moist and preventing it from drying too quickly, particularly in hot or windy Melbourne summer conditions. Contractors will typically apply curing compounds or keep the surface misted during the first 24 hours.
The pool is then filled slowly and carefully — again, too-rapid filling of a new surface can cause issues. Initial filling typically takes 12–24 hours, depending on pool size and water pressure.
Step 6: The Start-Up Chemical Process
This is where the long-term performance of your new surface is largely determined — and it’s a step that’s critically important to get right.
New plaster and aggregate surfaces leach calcium and other minerals into the water during the initial cure period. If the water chemistry isn’t carefully managed during the first two to four weeks, the surface can develop permanent staining, scaling, or etching that no amount of later chemical treatment will reverse.
The start-up process involves:
Initial water balancing — the fill water is tested and adjusted for pH, calcium hardness, alkalinity, and stabiliser levels before anything else. Incorrect chemistry during start-up is a leading cause of new surface problems.
Brushing — new plaster surfaces need to be brushed thoroughly at least twice daily for the first week to two weeks. This removes plaster dust and prevents it from settling and bonding to the surface, which would create rough patches and staining.
Chemical monitoring and adjustment — the water chemistry will shift daily during the cure period as the surface leaches minerals. Regular pool water testing and adjustment throughout this period is essential, not optional.
Avoiding certain chemicals initially — some sanitisers and algaecides are not recommended during the first weeks on a new surface. Your contractor or pool technician should provide specific guidance on what to use and when.
Many pool owners make the mistake of treating a newly resurfaced pool like an established one. The start-up period genuinely requires additional attention and careful chemical balancing — getting it right protects a significant financial investment for the full lifespan of the new surface.
How Long Does Pool Resurfacing Take?
For a standard residential pool in Melbourne, expect:
- Draining: 4–8 hours
- Preparation: 1–2 days (longer for pools with significant damage or large surfaces)
- Application: 1 day for plaster/aggregate; longer for tiling
- Curing and filling: 1–2 days
- Start-up period before swimming: 1–2 weeks minimum for plaster; longer is better
From draining to swimming, allow two to three weeks for a plaster or aggregate finish under normal conditions. Tiling projects take longer. This timeline is important to factor into your scheduling — particularly for Melbourne owners who want to be pool-ready for spring and summer.
Timing your resurfacing for late winter or early spring means the start-up period is completed before the peak swimming season begins. Winter pool maintenance in Melbourne is a useful read if you’re considering the off-season timing advantage — a pool that’s properly maintained through winter arrives at resurfacing in better condition than one that’s been left.
What Does Pool Resurfacing Cost in Melbourne?
Resurfacing costs vary considerably based on pool size, surface type chosen, condition of the existing surface, and any additional repairs required. As a general guide for Melbourne:
Marble plaster — typically the most affordable option per square metre, suitable for budget-conscious renovations where the pool will be sold or the owner prefers to defer higher investment.
Pebblecrete / Exposed aggregate — mid to upper range, reflecting the additional material and skilled application required. The most popular choice for Melbourne pools combining durability, aesthetics, and value.
Fibreglass coating — varies depending on preparation requirements and existing shell condition.
Tiling — the premium option, priced accordingly. Glass mosaic tiling at the high end can represent a substantial investment for a full-pool tile finish.
Any structural repairs, coping work, or equipment replacement needed before or during resurfacing adds to the total. A pre-resurfacing inspection that identifies all required work upfront avoids unpleasant surprises mid-project.
If you’re purchasing a property with a pool, a pre-purchase pool inspection or real estate pool inspection will identify whether resurfacing is needed and give you accurate cost expectations to factor into your purchase negotiations.
After Resurfacing: Keeping the New Surface in Excellent Condition
A properly resurfaced pool, maintained well, should last 15 to 20 years before needing attention again. The factors that most directly determine lifespan are water chemistry and mechanical care.
Maintain correct water chemistry consistently: This is the single most important thing you can do. Water that runs chronically low in pH etches and dissolves plaster. Water with excessive calcium hardness scales and stains. Regular pool water testing — at a minimum fortnightly during the swimming season — keeps chemistry in the ranges that protect the surface.
Brush the pool walls and floor regularly: Even after the start-up period, regular brushing prevents algae from taking hold and keeps the surface clean. This is especially important for pebblecrete, where the textured surface can harbour algae in the crevices between pebbles.
Keep the filter clean and running adequately: Dirty, under-performing filtration leads to water quality problems that progressively damage the pool surface. Pool filter cleaning is a straightforward maintenance step that directly protects your resurfacing investment.
Address staining early: New stains on a fresh surface are far easier to remove than established ones. If you notice discolouration developing, address it promptly rather than letting it set.
Professional pool maintenance on a regular schedule takes the management of all these factors off your hands — and for a newly resurfaced pool, the consistency of professional care during the first swimming season is particularly valuable.
The Bottom Line
Pool resurfacing is a significant investment that, when done properly, transforms the look, feel, and longevity of your pool for the next decade and a half or more. The key to getting the most from it is understanding the process — particularly the preparation quality and start-up period — and choosing a contractor experienced enough to execute both correctly.
If your pool is showing signs of surface deterioration, the sooner you act, the better. Continued use of a degraded surface accelerates the damage and often means more extensive preparation work when resurfacing does eventually happen.
