We know how much care goes into maintaining a beautiful, safe, and enjoyable pool. One key part of that upkeep is your pool’s plaster. While you might not think about it often, plaster is the smooth layer on your pool’s surface that keeps the walls safe to touch, helps prevent leaks, and even enhances the pool’s appearance. But when plaster starts to wear down, it can lead to some big problems.
In this post, we’ll break down why plaster condition is so important for your pool, how to tell if your plaster needs attention, and why keeping it in good shape can save you money and hassle in the long run. By the end, you’ll see how this smooth surface does a lot to protect and beautify your pool!

What is Pool Plaster, and Why is it Important?
Pool plaster is the layer of material that coats the interior surface of your pool. Made from a blend of cement, water, and fine sand or marble dust, pool plaster provides a smooth, waterproof barrier between the pool’s structural shell and the water. Think of it as the “skin” of your pool, protecting the structure and giving the interior a nice, clean finish.
Pool plaster is important for several reasons:
Waterproofing: The plaster layer acts as a barrier that helps prevent water from seeping into the concrete shell of your pool. Without it, water could leak through and damage the pool’s structure.
Safety: A well-maintained plaster surface feels smooth and comfortable to the touch, reducing the risk of scratches or cuts when people swim. Damaged plaster, on the other hand, can become rough, sharp, and uncomfortable.
Aesthetics: Plaster comes in various colors and can add to the beauty of your pool. Whether you prefer classic white or a deep blue finish, the plaster gives your pool its visual charm.
In short, plaster is more than just a pretty finish—it’s an essential part of keeping your pool safe, comfortable, and visually appealing.
Signs Your Pool Plaster Needs Attention
Over time, pool plaster can wear down due to constant exposure to water, chemicals, weather, and general use. Here are some common signs that your pool plaster might need a little TLC:
Discoloration: If you notice dark spots, streaks, or general discoloration in your pool, it’s likely a sign that the plaster is starting to break down. Minerals from the water or imbalances in pool chemicals can cause staining, leaving your plaster looking dingy.
Rough or Uneven Texture: When plaster wears down, it can become rough to the touch. This can be uncomfortable for swimmers and may even lead to scratches. Run your hand along the pool wall—if it feels rough, it might be time for a plaster update.
Cracks or Chips: Small cracks, chips, or “pitting” (tiny holes in the surface) are a clear sign that the plaster is aging and needs repair. Left unattended, cracks can worsen and allow water to seep into the structure of the pool, leading to costly damage.
Increased Algae Growth: Damaged plaster surfaces often become more porous, creating small pockets where algae can grow. If you notice more frequent algae blooms despite good cleaning habits, worn plaster might be to blame.
These signs may start off small, but if they’re ignored, they can lead to bigger problems, like leaks or structural damage.
Why Pool Plaster Condition Matters for Pool Health and Longevity
Taking care of your pool plaster isn’t just about appearances; it’s essential for the health and lifespan of your pool. Here’s why:
Protects the Pool’s Structure: The plaster layer shields the concrete or gunite shell from water. Without a solid plaster coating, water can seep through and weaken the structure, leading to leaks and, eventually, more significant structural problems.
Improves Safety for Swimmers: Rough, cracked plaster can create safety hazards for swimmers. Keeping your plaster smooth and even helps prevent scrapes and injuries, making the pool a safer place to enjoy.
Reduces Maintenance Efforts: When plaster becomes porous, it traps dirt, algae, and bacteria more easily, making it harder to keep your pool clean. A smooth plaster surface requires less scrubbing and fewer chemicals, which can save you time and money on maintenance.
Enhances Pool Appearance: Fresh, well-maintained plaster gives your pool a beautiful, inviting look. A worn-out plaster surface can make the entire pool look old, even if everything else is in good shape. Replastering your pool can make it look new again.
Good plaster condition can keep your pool water clearer, reduce chemical use, and make maintenance a lot easier.
Types of Pool Plaster and Options for Resurfacing
If your pool plaster is showing signs of wear, it might be time for resurfacing. Pool resurfacing involves applying a new layer of plaster to refresh the surface and restore its protective qualities. Here are some common options for pool plaster resurfacing:
Traditional White Plaster: This classic option is affordable and provides a smooth, clean look. While it’s durable, white plaster may show stains more easily over time and typically lasts about 7–10 years.
Colored Plaster: For a little more personality, colored plaster can add visual interest to your pool. It comes in a variety of shades and can make the pool water appear deeper or brighter.
Quartz Plaster: This plaster mix includes crushed quartz, making it more resistant to stains and providing a more polished, attractive finish. Quartz plaster tends to last longer than standard plaster, often around 10–15 years.
Pebble Finish: Pebble finishes use a mix of smooth stones embedded in the plaster for a natural, textured look. This option is highly durable, resistant to stains, and long-lasting, with a lifespan of around 15–20 years.
Polished Aggregate: This option combines fine stones with cement and is polished to a smooth, glossy finish. It’s highly durable, luxurious, and can last up to 20 years or more with proper care.
Each option offers different advantages in terms of appearance, durability, and maintenance. Our team at Infinity Pool Solutions can help you choose the right resurfacing option based on your needs and preferences.
The Process of Resurfacing Pool Plaster
Resurfacing your pool’s plaster is a big job, but it’s one that our team handles with care and professionalism. Here’s a quick overview of what to expect when we resurface your pool:
Drain the Pool: First, we’ll safely drain the water from your pool to expose the existing plaster.
Prepare the Surface: We’ll clean and sand the old plaster, making sure the surface is ready for a new coat. This includes filling any cracks or holes and smoothing rough areas.
Apply New Plaster: Next, we apply the new layer of plaster or aggregate finish, carefully smoothing it to ensure an even, durable surface.
Refill and Balance: Once the plaster is set, we’ll refill the pool and balance the water chemistry to protect the new surface. Proper water balance is essential to help the plaster cure correctly and to prevent staining.
Initial Maintenance: For the first few weeks, we’ll guide you on brushing and monitoring the water balance to ensure the new plaster remains smooth and clear.
How to Care for Your Pool Plaster to Extend Its Life
Once you’ve invested in resurfacing your pool, you’ll want to keep it looking great for as long as possible. Here are some tips for taking care of your new pool plaster:
Balance Your Pool Chemicals: Keeping your pool water balanced is essential to prevent the plaster from corroding, staining, or becoming rough. Regularly test and adjust the water’s pH, alkalinity, and calcium hardness.
Brush the Pool Surface: Brushing your pool’s plaster regularly helps prevent algae and dirt from settling into the surface, keeping it smooth and clean.
Use Pool-Friendly Cleaning Products: Some harsh chemicals or cleaning tools can damage plaster. Stick to pool-safe cleaners and gentle tools to avoid scratching or wearing down the surface.
Schedule Routine Maintenance: Regular check-ups by pool professionals can help catch any small issues before they become bigger problems. A well-maintained pool will keep its plaster looking good for years to come.
