A well-maintained pool should feel smooth, look clean, and hold up against years of water, chemicals, and sun. But even the strongest surfaces eventually start to show signs of wear. The trouble is that many early warning signs are subtle. They often go unnoticed until the damage becomes more obvious and expensive to repair. Knowing what to look for can help you act early, protect your investment, and avoid a full rebuild when a simple pool resurfacing job could solve the issue.
Rough Patches That Catch on Skin or Swimwear
One of the earliest and most common signs of pool surface breakdown is roughness. If swimmers feel scratchy areas underfoot or notice their swimwear catching on the surface, it is a strong indication that the top layer is wearing away. This usually happens because the plaster or gelcoat has started to erode, exposing coarser material beneath. Rough patches can lead to minor injuries, make the pool uncomfortable to use, and get worse quickly if left unaddressed. When these areas appear, resurfacing is often the best way to restore smoothness and prevent further deterioration.
Stubborn Stains That Do Not Scrub Off
Pools naturally develop some staining from minerals, leaves, and regular use. But when stains become impossible to remove, even with professional cleaning, the problem may be deeper than it looks. Persistent discolouration often means the surface is aging, porous, or breaking down. As the finish wears thin, it can absorb minerals and organic matter, resulting in stains that are permanently embedded. Rather than trying stronger chemicals or abrasive cleaning methods, which only damage the surface further, resurfacing provides a long-lasting solution that brings back a clean and uniform appearance.
Chalking or Powdery Residue on the Surface
If you notice a fine, white, powdery substance on your pool walls or steps, this is a telltale sign of surface degradation. Known as chalking, it occurs when the binders in the plaster or coating begin to weaken. Over time, the surface becomes soft and starts to dissolve into the water. Not only is this unattractive, but it disrupts water chemistry, making it harder to keep your pool balanced. If chalking is left untreated, the surface will continue to erode, eventually leaving you with roughness, pitting, and structural risks. At this stage, pool resurfacing in Perth is usually the recommended fix.
Cracks That Seem Small but Spread Over Time
Hairline cracks often appear harmless, but they are one of the clearest signs your surface is breaking down. While some cracks are surface-level only, others can grow deeper and allow water to penetrate the shell. This can create more serious problems, such as leaks, rusting of internal components, or lifting of the surface. Even cosmetic cracks can widen quickly due to temperature changes and pool movement. Rather than patching individual cracks, resurfacing provides a uniform protective layer that seals the pool and extends the lifespan of the entire structure.
Fading Colour and a Dull, Lifeless Appearance
Sun, chemicals, and years of heavy use can strip the colour from your pool surface. If your once bright blue or crisp white finish now looks faded, blotchy, or dull, it usually means the outer layer has thinned or lost its UV protection. While fading alone does not always mean immediate danger, it is an early signal that the material is no longer performing at its best. A fresh resurfacing not only restores your pool’s aesthetic but also improves durability, water clarity, and resistance to sunlight.
Increased Algae Growth and Difficulty Maintaining Water Balance
If you are noticing algae returning more often than usual, even with proper cleaning and chemical use, the problem could be the surface itself. As a pool ages, it becomes more porous, creating tiny pockets where algae can attach and thrive. A worn surface also interferes with water circulation, making it harder for the sanitiser to work effectively. This leads to higher chemical costs and more frequent maintenance. Resurfacing gives the pool a smooth, non-porous finish that discourages algae and makes water balance far easier to maintain.
Pitting or Small Divots on the Pool Floor and Walls
Pitting looks like small craters or tiny holes forming across your pool’s surface. These are not only unsightly but also a clear indicator of material breakdown. Pitting can occur from chemical imbalance, aggressive cleaning, or simply age. While small pits may not cause immediate issues, they can spread and deepen, eventually becoming expensive to fix. A new surface solves the problem by smoothing the entire shell and protecting it against further erosion.
Metal Staining and Rust Marks Around Fixtures
If you are seeing brown, orange, or dark streaks near lights, ladders, or rail fittings, it could be a sign that the protective layer around these fixtures has worn away. Once the surface becomes thin, metal parts can begin to oxidise, creating stains that are very difficult to remove. Rust marks also suggest that moisture is reaching areas it should not, which can compromise the structure over time. Resurfacing stops this by sealing the interior and providing a barrier between water and metal components.
Why Early Action Matters
Pool problems rarely stay small. What begins as a bit of roughness or minor staining can quickly turn into costly repairs if ignored. Acting early helps you avoid structural damage, high maintenance costs, and the need for a full renovation. Resurfacing is a cost-effective way to renew the entire pool, improve performance, and extend its usable life for many years.
The Simple Solution to a Failing Surface
If you notice any of these hidden signs, it may be time to consider professional resurfacing. It revitalises your pool, improves safety, restores colour, and prevents small issues from becoming bigger, more expensive problems. By staying alert to the early indicators of wear, you can protect your investment and enjoy a pool that looks great and performs well season after season.
