What Are the Signs You Need Gunite Pool Resurfacing?
Your pool cannot speak, but it does send some very clear signals when its surface is failing. Ignoring these signs can lead to bigger and more expensive problems down the road. You should look for a few key indicators that show it’s time for action.
Many owners of gunite pools first notice issues with staining. These are not just leaves that can be brushed away, but deep-set stains from minerals, metals, or stubborn algae that have worked their way into the plaster. If your weekly pool maintenance just cannot lift them, the surface itself is likely the problem.
Another major sign that you need gunite pool resurfacing is the texture of the existing pool. Does the bottom of your pool feel like coarse sandpaper? This condition, often called “pool toe,” happens when the smooth plaster has worn away, exposing the rougher gunite shell underneath, making the concrete pool uncomfortable and potentially hazardous.
You may also see visible cracks. Small, web-like cracks, known as crazing, are often an early warning sign that the plaster finish is aging. But larger cracks, called structural cracks, can be a serious symptom that might point to leaks and water loss, a problem that definitely needs professional attention before gunite pool resurfacing.
Have you ever noticed a chalky substance on your fingers after running them along the pool wall? This is the plaster material breaking down over time, a process called etching. Eventually, this can lead to spots of the plaster actually peeling or flaking away from the pool shell, which is a clear sign the surface has reached the end of its life and needs pool replastering.
The Most Popular Pool Finish Options
The best part about resurfacing your gunite swimming pool is the chance to upgrade its look and feel completely. You have several resurfacing options for a new finish, each with its own benefits. This is your opportunity to go from a standard pool to a custom backyard retreat that enhances your outdoor living space.
Standard Plaster (Marcite)
Standard white plaster is the classic choice many of us grew up with. It is a simple mixture of white cement, marble dust, and water. This combination creates that traditional, light blue water color that looks so inviting in many swimming pools.
Its main benefit is being the most affordable gunite pool resurfacing option. However, it also has the shortest lifespan, typically lasting around 7 to 10 years before showing wear. It is also more porous than other finishes, which means it can stain more easily if your pool chemistry is not perfectly maintained.
Polished Finishes (Quartz)
A big step up from standard pool plaster is a quartz aggregate finish. Here, tiny quartz crystals are mixed into the plaster, often referred to as plaster quartz. The result is a much more durable and stain-resistant surface that looks fantastic.
The quartz adds a subtle sparkle to your pool water, which can be beautiful on a sunny day, and there are many custom blends available to change the water’s hue. It feels smooth to the touch and holds its color far better than standard plaster. You can expect a quartz surface to last about 10 to 15 years with proper care.
Aggregate Finishes (Pebble)
For a more natural, riverbed look, a pebble finish like Pebble Tec is an amazing choice. This surface mixes small, polished pebbles with cement, and some homeowners add glass beads for extra shimmer. This is by far one of the most durable residential pool finishes available today, offering increased durability.
It is incredibly tough, stain-resistant, and can last upwards of 20 years or more with proper maintenance. While older pebble surfaces had a reputation for being rough, modern “mini pebble” options offer a much smoother surface. This gives you durability without sacrificing comfort, making it an excellent choice for families planning for gunite pool resurfacing.
All-Tile Finish
If you are looking for the absolute top-tier option, an all-tile finish is it. The entire interior of your pool is covered in either ceramic, porcelain, or glass pool tiles. The design possibilities with a tile pool are virtually endless, allowing for intricate mosaics and patterns.
Tile is the most durable surface and the easiest to keep clean because it is non-porous, preventing algae from getting a foothold. A quality tile surface can last for decades. But this premium pool resurfacing option comes with the highest price tag and a much longer installation time.
| Finish Type | Average Lifespan | Relative Cost | Texture |
|---|---|---|---|
| Standard Plaster | 7-10 years | $ | Smooth, can become rough |
| Quartz Finish | 10-15 years | $$ | Smooth with a slight texture |
| Pebble Finish | 20+ years | $$$ | Textured, varies by pebble size |
| All-Tile | Lifetime | $$$$ | Very smooth |
Understanding the Gunite Pool Resurfacing Process Step-by-Step
Seeing a major pool construction project in your backyard can be stressful. But knowing the specific steps can make the entire experience much smoother. Here is a breakdown of what a professional gunite pool resurfacing project looks like.
- Draining the Pool
First, the resurfacing company will completely drain your pool using a submersible pump. They will make sure the water is discharged properly according to local regulations. Once empty, the real work of the pool resurfacing process can start. - Preparing the Surface
This is the loudest and dustiest part of the job. The crew will use powerful tools to chip away the old, failing pool plaster. They need to remove the weak top layer to get to the solid gunite swimming shell beneath it, which provides a strong base for the new finish. - Inspection and Repairs
With the old surface gone, the team can inspect the gunite shell for any cracks or weak spots. They will repair these issues now to make the structure sound. They will also check fittings and fixtures, like lights and drains, and prepare them for the new surface to make the surface ready for the next step. - Bond Coat and Acid Wash
To help the new finish stick properly, a bond coat is often applied to the entire gunite shell. The surface is also typically acid-washed to clean and etch the concrete material, creating an ideal surface for the new material to adhere to. This is a vital step for a long-lasting job when resurfacing gunite. - Applying the New Finish
Now for the exciting part of the resurfacing process. A skilled crew will mix your chosen finish material, whether it is plaster, quartz, or pebble, using quality materials. They apply it by hand, using trowels to create a smooth surface evenly across the pool’s entire interior, which requires considerable skill. - Filling the Pool
After the new surface has had some time to set (usually about 24 hours), the pool can start to be refilled with fresh water. The filling process needs to be done carefully. Professionals often place a soft cloth over the end of the hose to prevent streaks on the new plaster as the pool fills. - Initial Water Treatment and Startup
This final stage of gunite pool resurfacing is critically important. The first 30 days of a new pool surface’s life, known as the curing period, determine its long-term health and appearance. The startup involves balancing the water chemistry and frequent brushing to allow the plaster to cure correctly, a critical step for longevity.
Let’s Talk About Cost: What’s the Investment?
A gunite pool resurfacing project is a serious investment in your home. The total resurfacing cost can vary a lot based on a few key factors. It is a good idea to know what influences the price before you start getting a free estimate from a pool resurfacing company.
The biggest factor is the size of your pool. The pool resurfacing cost is often calculated by the square foot of the interior surface area. A larger pool simply requires more materials and more labor to complete, which increases the price.
Your choice of finish for gunite pool resurfacing will also heavily affect the final price. Standard plaster is the most economical, while an all-tile surface is the most expensive. Pebble and quartz finishes fall somewhere in the middle, offering a nice balance of durability and cost for many homeowners and are popular pool options.
The current condition of your gunite swimming pool also plays a part. If the existing gunite shell needs a lot of crack repair or other prep work, that will add to the labor costs. A pool in relatively good shape will be more straightforward to resurface, and many homeowners use this opportunity for a full pool remodel, updating the pool deck or adding water features at the same time.
As a rough guide for an average-sized pool, you might see prices ranging from $7,000 to $15,000 for standard plaster. For a more durable aggregate finish like pebble or quartz, that range could be from $12,000 to over $25,000. These are just ballpark figures, and you will need to get a specific quote for your project from a reputable contractor who uses the highest quality materials.
How Long Does a New Pool Surface Last?
One of the best things about resurfacing your pool is the long-term value it adds. You are not just fixing a problem for next summer; you are setting yourself up for years of enjoyment. How many years you get depends heavily on two things: the quality of the installation and your ongoing maintenance.
Assuming a professional installation during gunite pool resurfacing, the type of finish you choose dictates the expected lifespan. As mentioned, a plaster surface might give you about a decade of service. A quartz finish can push that to 15 years, and a pebble surface can easily last over 20 years.
But the real key to longevity is proper maintenance. Maintaining balanced water chemistry is the single most important thing you can do to protect your investment. Consistently testing your water and keeping it within the ideal ranges prevents scaling and etching that can damage the surface over time. Regular brushing and cleaning also go a long way in achieving customer satisfaction with the final product.
Frequently Asked Questions About Resurfacing
How long does the entire gunite pool resurfacing process take?
The timeline can vary based on the size of the pool, the extent of repairs needed, and weather conditions. Generally, a typical resurfacing project takes about 5 to 7 days from draining the pool to beginning the refill. The subsequent 30-day curing period requires specific care but does not involve active construction.
Can I change my pool’s color when I resurface it?
Absolutely. This is one of the most exciting gunite pool resurfacing options. With plaster, quartz, and pebble finishes, you can choose from a wide array of colors and custom blends to dramatically change your pool’s water color from a light sky blue to a deep ocean blue or even a lagoon-style green.
Is it okay to use my pool immediately after it’s refilled?
No, you will need to wait. The new surface needs time to cure properly underwater. Most pool resurfacing professionals recommend waiting at least 7 days before swimming and avoiding harsh chemical shocks or automatic pool cleaners for the first 3 to 4 weeks.
Should I update my pool tile at the same time?
This is the perfect time for a pool tile update. Since the pool will be empty and the old surface is being removed, replacing the waterline tile is much easier and more cost-effective than doing it as a separate project. This allows for a completely refreshed look as part of your pool remodeling project.
What is the difference between pool replastering and resurfacing?
These terms are often used interchangeably, especially for gunite pools. Gunite pool resurfacing is the broader term that covers applying any new interior surface. Pool replastering specifically refers to applying a new layer of plaster, which is just one of the many available resurfacing options.
Conclusion
Giving your pool a new surface is one of the best home improvement projects you can do. It is not just a repair; it is a full-blown renovation that boosts your property value and restores the beauty of your backyard. Thinking about a gunite pool resurfacing project means you are ready to fix those cracks, stains, and rough spots for good.
From understanding the different pool finish options to knowing the process pool professionals follow, you have a much clearer picture. The highest quality work from a professional contractor will leave you with a stunning pool you can be proud of for years. Now you know what it takes to bring your pool back to its former glory.
