Avoid Damaging Your Swimming Pool Surface

Any pool surface type can be easily stained to any product containing acid, like a battery-operated toy (when the batteries explode from being on the pool bottom) or a 3” trichlor tablet, which includes a type of acid in cyanuric acid and has a pH under 3. Roof nails, staples holding up Christmas lights, and fertilizer pellets can also cause rust stains in your pool. 



Fiberglass and vinyl pool surface chemicals can sometimes burn or bleach the surface. Don’t use granular Trichlor and cal hypo should not be added directly to the vinyl pool; I prefer adding cal hypo through the skimmer to avoid bleaching out the vinyl liner; in some cases, manufacturers will void your warranty on your fiberglass or vinyl pool if you use trichlor tablets in these pools. The pH is relatively low in a fiberglass and vinyl pool since it is plastic, and using any pool chemical with a low pH, like Trichlor, can lead to metal staining from the equipment as the low pH reacts with metal components. Dichlor has a pH of about seven, so it is safe to use in a fiberglass or vinyl pool. Liquid chlorine is also safe to use directly in these pool surface types. 

Plaster is a standard surface type made with cement and white marble aggregate. The problem with white plaster is that any stain becomes very evident, and in many cases, the pool chemistry affects the color. You can also go with a color plaster, making your pool stand out and look great. The problem with the colored plaster is that the mottling or pattern discoloration is very apparent and visible over time. But it is still the most affordable pool surface type on the market.

Quartz is a surface type that combines a quartz aggregate and polymer-modified cement making, which is more durable than standard plaster and gives it a longer lifespan. You can also get Quartz in various colors; the finish holds up well against chemicals and is more stain-resistant. It is a hard surface type that is very smooth and swimmer-friendly—an excellent choice and a step up from standard plaster.

Pebble Tec is a well-established brand that combines cement and small pebbles and stones. Pebble Tec is highly durable and long-lasting. There is a great variety of surface types and colors to choose from. The drawback is that the surface can be rough on the feet, but it resists stains, looks uniform throughout, and lasts over 15-20 years. It is a more expensive choice, but you can't beat the durability and look of Pebble Tec.

Wet Edge is much like Pebble Tec but at the same time different. Mike Willard of Your Pool Builder in Texas recommends and uses the Wet Edge surface. Wet Edge aggregate finishes are durable and beautiful. All Wet Edge finishes are handcrafted and custom-made for each swimming pool. The finish is white cement-based but with blended polymers to make them denser and more durable. There are several different Wet Edge Surface types, and you can learn more directly from their 

Of the different surface types, the Wet Edge is the premium choice. But your budget might not make it the choice for your pool build, so I recommend going with a Quartz finish versus standard white plaster if you have to go down.

Fiberglass pool surfaces are famous for swimming pools due to their durability, smooth finish, and low maintenance. Here are some critical points about fiberglass pool surfaces:

Material Composition: Fiberglass pools are made of reinforced plastic with fiberglass strands. The pool shell is created by layering fiberglass and resin in a mold.

Smooth Finish: One of the main advantages of fiberglass pools is their soft and non-porous surface. This smooth finish is comfortable for swimmers, inhibits algae growth, and makes cleaning easier.

Durability: Fiberglass is known for its strength and durability. Fiberglass pools are less likely to crack over time than concrete pools, and they are more flexible, making them resistant to ground movements.

Low Maintenance: Fiberglass pools generally require less maintenance than other types. The smooth surface helps prevent the buildup of algae and other contaminants, reducing the need for frequent cleaning and chemical treatments.

Installation Time: Fiberglass pools are often quicker to install than concrete pools. The pool shell is pre-manufactured and delivered to the site, making the installation more efficient.

Cost: While the initial cost of a fiberglass pool may be higher than that of a vinyl liner pool, it is often comparable to or lower than that of a concrete pool. Additionally, the lower maintenance requirements can lead to cost savings over time.

Design Options: Fiberglass pools come in various shapes and sizes, and some manufacturers offer customization options. However, the design choices may be more limited compared to concrete pools.

Resistant to Stains: Fiberglass surfaces are less prone to staining than other pool surfaces. This is beneficial in maintaining the pool's aesthetic appeal.

Vinyl pool surfaces are another standard option for swimming pools, offering advantages and considerations. Here are some critical points about vinyl pool surfaces:

Material Composition: Vinyl pools have a flexible liner made of vinyl material that is installed over the pool's structure, which is typically made of metal, wood, or concrete.

Smooth and Non-Porous: Vinyl pool surfaces are smooth and non-porous, like fiberglass. This smooth surface is comfortable for swimmers and helps resist algae growth.

Affordability: Vinyl pools are often more affordable upfront than fiberglass and concrete pools. This makes them a popular choice for homeowners on a budget.

Versatility in Design: Vinyl pool liners come in various patterns, colors, and designs, providing flexibility for customization. This allows pool owners to achieve a specific aesthetic that suits their preferences.

Comfortable Surface: The vinyl liner provides a softer and more comfortable surface for swimmers than concrete. This can be particularly appealing for families with children.

Easy to Install and Repair: Vinyl pool liners are relatively easy to install and can be replaced or repaired more quickly than other pool surfaces. However, they are susceptible to punctures or tears, which may require patching or replacement.
Limited Lifespan: Vinyl pool liners have a limited lifespan compared to fiberglass or concrete surfaces. They typically last around 10 to 15 years before needing replacement.

Maintenance Requirements: Vinyl pool surfaces require regular maintenance to ensure longevity. Proper water chemistry and balanced pool maintenance are essential to prevent liner fading or damage.

Susceptibility to Sharp Objects: While vinyl is durable, sharp objects can puncture or tear it. Care should be taken to avoid introducing sharp items into the pool.

Resilience to Freezing Conditions: Vinyl pools are less prone to cracking in freezing conditions than concrete pools. However, precautions should still be taken to winterize the pool properly.
