Whether you’ve been a pool owner for years or just recently had one installed, understanding the maintenance and repair options available is crucial to preserving your investment. Two terms that often come up when discussing pool upkeep are resurfacing and replastering, and while they may sound similar, they refer to different processes with distinct costs, materials, and long-term implications.
In this comprehensive guide, we’ll explore the key differences between resurfacing and replastering a pool, helping you make an informed decision based on your pool’s condition, your budget, and your long-term goals.
Understanding the Basics: What Does Each Term Mean?
Before diving into the finer differences between resurfacing and replastering, it’s important to define what each term means in the context of pool maintenance and renovation.
Resurfacing: A Comprehensive Upgrade
Resurfacing is a broad term that refers to the process of applying a new surface layer over the existing structure of the pool. This can involve removing or repairing the topmost layer and then replacing it with a new material, depending on the integrity of the existing structure.
There are several types of resurfacing materials available, including:
- Plaster (standard and aggregate blends)
- Tile
- Fiberglass
- Concrete overlays
Resurfacing often means more than just aesthetics; it may also involve structural fixes or modifications. It’s typically recommended when the current surface shows significant signs of wear, such as cracking, staining, or erosion, and needs a full, long-lasting restoration.
Replastering: A Surface-Level Fix
Replastering, in contrast, is a more specific process. It’s typically used in gunite or concrete pools and involves applying a new layer of plaster over the existing concrete shell. The old plaster is removed or acid-washed, and a fresh coat is applied to restore the pool’s appearance and smoothness.
Since replastering doesn’t usually involve structural changes, it’s more of an aesthetic and functional repair. It’s often the go-to choice when a pool’s structure remains sound, but the interior plaster has become uneven, rough, or discolored.
Key Differences Between Resurfacing and Replastering a Pool
To help you better understand which option might be right for your needs, let’s break down the core differences between resurfacing and replastering across a number of important factors:
| Aspect | Resurfacing | Replastering |
|---|---|---|
| Scope | Full surface replacement, including structural components | Only plaster layer replaced |
| Materials | Tiling, fiberglass, aggregate plaster, quartz, pebble finishes | Plaster (white or colored), marcite |
| Lifespan | 7–20+ years, depending on material type | 5–7 years |
| Cost | $4,000–$20,000+ | $2,500–$5,000 |
| Time Required | 2–6 weeks | 3–7 days |
| Customization | Highly customizable surface textures and colors | Limited options in terms of finishes |
| Best For | Pools with structural damage, outdated finishes, or requiring upgrades | Smooth surface restoration; relatively new or structurally sound pools |
While replastering offers a cost-effective, short-term solution, resurfacing provides a more durable, long-term alternative, especially when structural integrity is at stake.
When to Choose Replastering
There are specific indicators that signal it’s time to replaster your pool rather than go through a full-scale resurfacing project.
Check for These Signs
Before moving forward with replastering, pool owners should assess their current pool conditions. Replastering is ideal if the pool’s foundation (gunite or concrete) remains intact and the only visible issues are with the plaster surface.
Some signs that replastering might be the right choice:
- Plaster is worn, rough, or cracking but the structure underneath is in good condition.
- Calcium buildup or surface staining without structural issues.
- Pools less than 10 years old showing surface wear but no foundation damage.
It’s also important to consider that replastering can only be done a limited number of times without affecting the water depth negatively. Each replastering layer slightly reduces the water volume, so this is often considered the quick fix among pool rennovation methods.
Plaster Types for Replastering
When replastering, property owners have a few traditional options:
- White Marcite: A common, affordable white plaster composed of white Portland cement, marble dust, and water.
- Colored Plaster: Similar to white marcite but includes pigments for aesthetic appeal—longer curing time required.
- Aggregates (Quartz or Stone): High-end alternatives to basic marcite, providing greater durability and more visual appeal.
Remember, even though replastering can be ideal for surface fixes, it rarely addresses the underlying causes of long-term wear and may not be suitable for pools showing signs of structural deterioration.
When to Go for Resurfacing
Resurfacing is a major investment and not always necessary, but it becomes the better choice when the condition of the pool exceeds surface-level concerns.
Indicators That Resurfacing Is Needed
If your pool exhibits these signs, it’s likely time for a full surface overhaul:
- Potholes, large cracks, or uneven surfaces in the concrete shell.
- Chipping or significant damage that compromise the pool structure.
- Multiple replastering jobs over the years that have decreased the waterline.
- An outdated design or desire for an upgraded aesthetic or texture.
Additionally, if you’re renovating your home or planning backyard upgrades, resurfacing your pool to match the new design trends—such as pebble finishes or ceramic tiling—might be a fitting option.
Types of Pool Resurfacing Materials
Unlike replastering, resurfacing offers a wide variety of materials and finishes to meet specific durability, style, and budget needs.
Plaster Overlays and Aggregate Finishes
For homeowners who want something more durable than basic white plaster but don’t want a full structural change, aggregate finishes like quartz, pebble, and crushed marble are often ideal. These provide a more durable, visually appealing, and potentially stain-resistant finish.
Tile Surfaces
Tiling offers a luxurious look and much longer durability than basic plaster. Tile resurfacing is often used in high-end pools, in both full installation and in resurfacing projects. Tile can be made of ceramic, porcelain, glass, or natural stone and provides a seamless, customizable surface.
Fiberglass (for Certain Types of Pools)
Fiberglass is often used to fully renew older concrete pools. It involves installing a pre-formed fiberglass shell into the existing structure, dramatically reducing water permeability and future maintenance needs. However, this method requires precise fitting and may not be suitable for uniquely shaped pools.
Concrete and Shotcrete
Sometimes, resurfacing may require significant repair of the underlying concrete, including areas where the original structure is no longer solid. Shotcrete—a form of concrete applied with pressure—may be used as part of this process to restore structural integrity before a final surface material is applied.
Cost Considerations: Which Option Fits Your Budget?
Understanding the financial implications of resurfacing versus replastering is essential before making any decision.
Replastering Costs
Replastering is the more affordable of the two options, often ranging between $2,500 and $5,000 depending on the pool’s size, labor costs in your area, and material choices. For standard residential pools, replastering jobs usually take less than a week and provide a relatively quick fix.
Resurfacing Costs
Resurfacing typically ranges from $4,000 up to $20,000 or more, based on the type of finish you choose and the extent of structural repairs needed. Here’s a breakdown of price per material:
- Aggregate finishes: $5,000–$12,000
- Tile: $8,000–$20,000+
- Fiberglass: $10,000–$15,000
Although more expensive, resurfacing can provide a better return on investment, especially if you’re looking to sell your home or enjoy a lower maintenance pool for a longer period.
Time and Labor Involved
The amount of time your pool is out of commission is another factor worth considering when choosing between resurfacing and replastering.
Replastering Timeframe
Replastering is typically quick, with most professionals able to complete the job within 3 to 7 days. This involves draining the pool, pressure-washing the old plaster, applying the new material, and allowing enough time for curing based on the type of plaster used.
Resurfacing Timeframe
Resurfacing is a more complex process, which often takes 2 to 6 weeks to complete. This includes:
- Draining and preparing the structure
- Making repairs if the concrete shell has cracks or damage
- Applying the new surface layer
- Allowing for a longer drying and curing period
Depending on whether tile is hand-laid or custom-fitted fiberglass is used, delays can occur due to materials being custom-ordered or imported.
Lifespan and Long-Term Benefits
Each option comes with different longevity and benefits, directly influencing your ongoing maintenance needs.
Lifespan of Replastered Pools
Standard plaster finishes from replastering typically last around 5 to 7 years, although colored and aggregate finishes last a little longer—up to 10 years in many cases. These finishes may require more frequent brushing to prevent algae accumulation and can be more sensitive to pH changes in the water.
Lifespan of Resurfaced Pools
Modern resurfacing options can last 7 to 20+ years, depending on the material selected. Pebble finishes and quartz can last up to 15 years, while full tiling jobs can last 20 or more. Fiberglass also promises extended durability, especially when maintained properly.
Additionally, resurfacing often improves energy efficiency by minimizing water evaporation due to a smoother, more consistent surface. This also reduces chemical consumption over time.
Customization and Design Options
If aesthetics and personalization are a priority, resurfacing opens a world of design possibilities.
Replastering: Limited Aesthetic Options
Although you can choose different colored plasters or minor texture variations, replastering options are fairly limited compared to resurfacing. Expect simple white standard plaster, various shades of colored plaster, or basic quartz mixes.
Resurfacing: Versatile Design Palette
From natural looking pebble finishes that mimic beachside aesthetics to elegantly tiled surfaces that elevate backyard luxury, resurfacing delivers an array of choices to enhance your pool’s visual appeal.
Some of the most popular high-end finishes include:
- Pebble Tec finishes
- Crystal quartz surfaces
- Hand-laid mosaic tiles
- Custom ceramic and glass tiling
This level of customization also allows homeowners to match their pool to the rest of their outdoor living space.
Maintenance Requirements
After investing time and resources into either replastering or resurfacing, it’s important to understand how each affects maintenance moving forward.
Replastering and Ongoing Care
Plaster surfaces tend to be more porous than other resurfacing finishes, requiring:
- Regular scrubbing to prevent scale buildup
- More frequent water chemistry balancing
- Potential acid washing every few years to restore shine
If the chemistry isn’t carefully balanced, plaster finishes can etch or stain, leading to a less aesthetically appealing and more slippery surface.
Resurfacing and Maintenance Perks
Newer, advanced resurfacing materials like porcelain tile or natural stone reduce the likelihood of staining and offer smoother, easier-to-clean surfaces. Quartz or pebble-type finishes are more resistant to abrasion and chemical imbalances, making them popular for areas with fluctuating climate conditions.
Overall, resurfaced pools require less maintenance after the initial investment compared to replastered pools.
Conclusion: Which Option Is Right for You?
If you’re trying to decide whether to resurface or replaster your pool, the best approach involves evaluating:
- The structural condition of your pool’s foundation.
- Your budget and desired long-term maintenance costs.
- Your aesthetic preferences and customization aspirations.
Replastering is ideal for short-term fixes or when the pool’s structure is still in good shape. It’s budget-friendly and allows for a moderate visual upgrade without breaking the bank.
On the other hand, if you’re looking for a longer-lasting, durable finish with greater aesthetic possibilities—and especially if your pool’s structure is showing signs of wear—resurfacing is the better investment.
Before making a decision, consult with a licensed pool contractor who can assess your pool’s exact condition, history, and expected usage. With proper planning, your pool renovation choices will not only extend the life of your swimming pool, but also enhance your enjoyment for years to come.
Final Thoughts on Pool Surface Decisions
In summary, while replastering is more accessible and economical, resurfacing offers superior durability, design appeal, and long-term cost effectiveness. Resurfacing provides a structural renewal alongside aesthetic customization and should be considered if your pool is aging or experiencing wear beyond the surface. Replastering, while more affordable and quicker, is best utilized as a periodic maintenance step in a long-term plan. Knowing when to choose one over the other ensures your pool remains a source of relaxation, beauty, and value to your property for years to come.
Whether it’s replastering or resurfacing, making the right decision will help ensure your pool remains as functional and attractive as the day it was built.
Make Your Pool Shine with the Right Surface Choice
Investing in your pool’s surface is investing in your lifestyle and your home’s value. While replastering gives a fresh start for minor issues, resurfacing sets the stage for a next-level transformation. Make an educated decision by working with professionals, understanding your options, and planning according to your pool’s unique needs.
Always remember: A well-maintained surface means a longer life for your pool and less stress in the long run. Whether you choose resurfacing or replastering, the key is to ensure your pool remains a safe, enjoyable, and beautiful centerpiece of your backyard living space.
What is the difference between resurfacing and replastering a pool?
Resurfacing a pool involves applying a new layer of finish over the existing surface to repair imperfections and enhance appearance. This process typically includes removing old plaster or finish, repairing any cracks or damage in the underlying shell, and then applying a new surface coating, which can range from traditional plaster to more durable materials like quartz or pebble finishes. Resurfacing can transform the look of a pool while restoring its structural integrity.
Replastering, on the other hand, is a less intensive process focused primarily on replacing the interior plaster lining of the pool, which is the material that comes into direct contact with the water. It does not usually involve major structural repairs to the pool shell itself. Replastering is often done to address cosmetic issues such as staining, rough texture, or discoloration. While replastering is a form of resurfacing, it’s more limited in scope and is typically performed when the underlying structure of the pool is still in good condition.
Which option is better for an aging pool?
For an aging pool, resurfacing is generally the better option if there are signs of structural deterioration like cracks, surface erosion, or a compromised shell. Resurfacing allows technicians to repair these deeper issues before applying a new, durable surface. This can extend the life of the pool significantly and improve both its aesthetic appeal and performance. It’s a more comprehensive solution that can rejuvenate even the most worn-out pools.
Replastering may be sufficient if the pool’s structure is still solid and the only issues are with the interior finish—such as discoloration or minor surface wear. This option is more of a surface-level refresh rather than a full restoration. It’s often less costly and quicker than resurfacing but won’t address underlying structural concerns. If the pool is older but well-maintained, replastering can be a cost-effective way to enhance its appearance and functionality.
How long does each process last?
Resurfacing typically lasts between 10 to 15 years, depending on the materials used and how well the pool is maintained afterward. More durable finishes like quartz or pebble can extend the lifespan well beyond that of traditional plaster. Because resurfacing involves repairing the structure and applying a new, high-quality finish, it provides longer-lasting results. This makes it a more sustainable long-term investment for pool owners.
Replastering usually lasts around 5 to 10 years, depending on factors such as water chemistry, usage, and the type of plaster used. Since this process only replaces the innermost surface layer, it does not protect against or repair structural issues that may emerge over time. Therefore, replastering may need to be repeated more frequently, especially in older pools or those with fluctuating water conditions. For those looking for a longer-term solution, resurfacing is typically the better choice.
What are the signs that I need to resurface or replaster my pool?
You may need to resurface your pool if you notice deep cracks, uneven surfaces, spalling plaster, or exposed aggregate in the pool’s structure. These issues can indicate wear and tear at a structural level, and they can worsen over time, potentially leading to more significant damage. Resurfacing can resolve these issues by reinforcing the pool’s structure and covering it with a new finish that is both durable and visually appealing.
Signs that replastering may be necessary include a rough or gritty texture on the pool walls, visible staining, cloudy water despite good chemical balance, or a dull, discolored appearance. These are surface-level problems that don’t threaten the pool’s structural integrity but can affect aesthetics and user comfort. Replastering will restore the smooth finish, improve water clarity, and eliminate rough edges that can irritate swimmers’ skin.
How much do resurfacing and replastering cost?
Resurfacing a pool can be significantly more expensive than replastering, typically ranging from $5 to $10 per square foot or more depending on the materials selected and the extent of structural repairs needed. High-end finishes like glass bead or pebble blends will drive the cost higher, and if the pool requires major crack repairs or coping restoration, that adds to the overall expense. However, because resurfacing offers a more durable and long-lasting result, it can be more cost-effective over time.
Replastering is generally less expensive, averaging between $3 and $6 per square foot. The process doesn’t usually involve structural repairs or full demolition of the existing surface, which reduces both labor and material costs. However, because replastering doesn’t last as long as a full resurface, you may find yourself needing to repeat the process again in a few years. For this reason, the short-term savings of replastering may be offset by recurring maintenance costs over time.
Do I have to drain the pool for resurfacing or replastering?
Yes, for both resurfacing and replastering, the pool must be completely drained to allow technicians to properly access and prepare the surface. Draining ensures that all existing plaster or finish can be removed and that repairs can be made without interference from water. It also allows for a clean, stable surface on which to apply the new coating, which is crucial for achieving a durable, long-lasting result.
However, it’s worth noting that draining a pool can pose risks if not done correctly, especially for in-ground pools, which can float out of the ground due to hydrostatic pressure if the water table is high. This is why professionals typically handle the draining and refilling process. Whether resurfacing or replastering, it’s essential that proper techniques are used to protect the integrity of the pool structure during this phase.
How do I decide whether to resurface or replaster my pool?
To make the right decision, start by having a professional inspect your pool to assess its condition. If your pool shell is showing signs of structural damage—like cracks, uneven surfaces, or compromised coping—then resurfacing is likely the best option. This will not only improve appearance but also address underlying issues that could worsen over time. Resurfacing is a significant investment but often the most effective long-term solution.
If your pool’s structure is intact and the issues are purely cosmetic or related to the feel of the plaster, replastering may be sufficient. It offers a more budget-friendly and quicker alternative to full resurfacing. However, keep in mind that replastering needs to be repeated more frequently. Weigh your budget, long-term plans, and how much use your pool gets when making your decision. Consulting with a reputable pool contractor can help you determine which path is best for your specific situation.
