Your swimming pool is a significant investment in your home, and like any major investment, it requires regular maintenance to stay in top condition. One of the most important maintenance tasks you’ll face as a pool owner is replastering.

But how do you know when it’s time to replaster your pool? Many homeowners wait too long, leading to more extensive damage and higher repair costs. In this guide, we’ll walk you through the five telltale signs that your pool needs resurfacing and explain why addressing these issues sooner rather than later can save you both money and headaches.

1. Rough or Deteriorating Surface

If your pool’s interior surface feels rough, abrasive, or gritty, this is one of the most obvious signs that your plaster is wearing down. Over time, exposure to chemicals, sunlight, and regular use causes the smooth plaster surface to deteriorate and become increasingly rough.

A rough pool surface isn’t just uncomfortable; it’s actually dangerous. Swimmers can scrape their feet, hands, or knees on the abrasive surface, leading to cuts and scratches. Children are especially vulnerable since they often play and move around the pool’s walls and floor. If you’ve noticed family members or guests complaining about the texture, it’s time to consider pool resurfacing before your pool’s structure becomes compromised.

2. Visible Stains That Won’t Go Away

Have you noticed stubborn stains that persist no matter how much you brush or balance your water chemistry? While some staining is normal over the years, excessive or spreading stains indicate that your plaster has become porous and is absorbing minerals, metals, and other materials from your pool water.

Common stains include brown or rust-colored spots from metal deposits, gray or black stains from manganese, and greenish stains from copper or algae. When plaster is new and properly sealed, these materials can’t penetrate the surface. However, as plaster ages and its protective barrier breaks down, it becomes increasingly susceptible to permanent staining. Even if you improve your water chemistry, these stains won’t disappear because they’ve penetrated deep into the plaster. The cost to replaster your pool is a worthwhile investment when persistent staining makes your pool look old and uninviting.

3. Plaster Delamination or Flaking

Delamination occurs when the plaster begins separating from the underlying surface, creating hollow spots that eventually crack and flake off. You might notice pieces of plaster coming loose or areas where the plaster appears to be bubbling or peeling away from the pool shell.

This is a serious issue that requires immediate attention from a qualified pool contractor. Delamination doesn’t just look bad; it compromises the structural integrity of your pool. Once water gets behind the plaster, it can cause even more extensive damage to the underlying gunite or concrete, potentially affecting your concrete pool coping and other structural elements.

If you catch delamination early, pool resurfacing can address the problem before it spreads. Wait too long, and you might need more extensive pool restoration work that goes beyond simple replastering.

4. Frequent Water Loss or High Chemical Usage

Are you adding water to your pool more frequently than usual? Are you going through pool chemicals faster than normal? While these could indicate other issues, they’re often signs that your plaster has developed small cracks or has become porous.

When plaster deteriorates, it can develop tiny cracks that allow water to seep through, leading to water loss. Additionally, compromised plaster is more difficult to keep clean and balanced, requiring more chemicals to maintain proper water quality. The porous surface harbors bacteria and algae more easily, forcing you to use more sanitizers and algaecides.

Over time, the extra money spent on water and chemicals can actually exceed the cost to replaster your pool. Plus, excessive water loss can lead to soil erosion around your pool, potentially damaging your pool coping stones and deck.

5. Visible Cracks or Structural Damage

Small hairline cracks might seem harmless, but they’re warning signs that shouldn’t be ignored. While small surface cracks are relatively common, deeper or spreading cracks indicate more serious problems. These cracks can expand over time, especially with freeze-thaw cycles or ground movement.

Structural cracks allow water to penetrate behind the plaster, potentially damaging the pool shell itself. They can also affect surrounding features like pool tile and coping. What starts as a simple replastering job can turn into a major pool repair project if structural cracks are left unaddressed.
