When it comes to building or renovating a swimming pool, the choice of surface finish plays a vital role in determining not only the aesthetics but also the durability and maintenance requirements of the pool. Among the most popular and widely recommended options are pool pebble and plaster finishes. Both offer unique advantages and cater to different styles, budgets, and longevity expectations. In this comprehensive guide, we will explore everything you need to know about pool pebble and plaster finishes—how they’re applied, their pros and cons, maintenance requirements, cost implications, and how to choose the right one for your pool.
Understanding Pool Finishes: The Basics
Pool Pebble and Plaster are the final layer applied to the interior surface of a swimming pool, sealing the shell and providing the desired texture and color. They serve both a functional and an aesthetic purpose—protecting the pool structure from water damage while also contributing to its visual appeal.
There are several types of pool finishes, including tiles, fiberglass, quartz, plaster, and pebbles. However, plaster and pebble finishes are two of the most commonly chosen options for residential and commercial pools due to their balance of affordability, beauty, and durability.
What Is Pool Plaster?
Pool Pebble and Plaster is a classic and time-tested finish that has been used in pools for over a century. Traditionally made from a mixture of white cement, water, and marble dust or limestone sand, pool plaster offers a smooth and clean appearance. It is typically white, which gives pools that signature bright blue look, though other colors can be added for different effects.
Plaster finishes are usually troweled by hand and can be completed relatively quickly by professionals. Although one of the most affordable pool finishes, plaster offers a timeless look that many pool owners still prefer.
Advantages of Pool Plaster
Cost-Effective: Plaster is generally the most affordable pool finish option, making it ideal for budget-conscious homeowners or large commercial installations.
Classic Appearance: The smooth, clean look of white plaster remains a staple for traditional pools and gives water a sparkling blue hue.
Ease of Application: The process of applying plaster is well-understood by most pool professionals, resulting in a consistent finish with minimal hassle.
Drawbacks of Pool Plaster
Shorter Lifespan: Standard plaster finishes typically last between 7 to 10 years before needing resurfacing, especially in high-use or poorly maintained pools.
Prone to Staining and Etching: The porous surface can absorb minerals and chemicals, leading to discoloration or surface damage over time.
Frequent Maintenance: Requires regular chemical balancing and brushing to prevent algae and mineral buildup.
What Is Pool Pebble Finish?
Pool Pebble and Plaster, often known by brand names like PebbleTec or PebbleSheen, are created by combining small, naturally tumbled pebbles with cement and sometimes polymer additives. This mixture is hand-troweled and then water-blasted to expose the pebbles, resulting in a textured, natural-looking surface.
Available in a wide array of colors and textures, pebble finishes are a favorite for those looking to give their pool a lagoon-like or earthy aesthetic. The finish is more durable than plaster and typically lasts longer, making it a premium choice for many homeowners.
Advantages of Pool Pebble
Exceptional Durability: Pebble finishes can last up to 20 years or more with proper care, significantly outlasting plaster.
Aesthetic Versatility: Available in various colors and pebble sizes, this product allows for a truly custom look that resembles natural bodies of water.
Stain Resistance: Less porous than plaster, reducing the risk of staining or algae growth.
Textured Feel: The tactile surface offers improved traction, providing a safety benefit for swimmers.
Drawbacks of Pool Pebble
Higher Cost: The materials and labor involved in pebble finishes are more expensive, often making this a premium option.
Rougher Texture: Some users may find the textured surface uncomfortable underfoot, especially with larger pebbles.
Installation Complexity: Requires skilled technicians for proper application and uniform results.
Maintenance Tips for Long-Lasting Results
Whether you opt for plaster or pebble, proper pool maintenance is essential for preserving the finish and extending its lifespan.
Maintain Proper Chemical Balance
Keep pH, alkalinity, calcium hardness, and chlorine levels within the recommended ranges. Poor water chemistry is one of the leading causes of surface damage and staining.
Brush Regularly
Use a pool brush to clean the surfaces at least once a week. This prevents algae buildup and removes debris that can stain or damage the finish.
Monitor for Scaling or Etching
Watch for white scale deposits (indicating excessive calcium) or surface etching (indicating insufficient calcium). Address chemical imbalances immediately.
Schedule Regular Inspections
Have a pool professional inspect your pool every year for cracks, discoloration, or early signs of wear.
Use a Pool Cover
When not in use, a pool cover can reduce UV exposure and chemical evaporation, both of which help prolong your surface finish.
Cost Considerations: Investment vs. Longevity
While plaster may initially cost $4–$6 per square foot, pebble finishes typically range from $8–$12 per square foot. However, pebble finishes may last twice as long or more than plaster, reducing long-term resurfacing costs. If you plan to live in your home long-term or want fewer headaches with pool upkeep, the higher initial investment in pebble could save money and time over the years.
Conclusion
Ultimately, both Pool Pebble and Plaster offer distinctive benefits. Your decision should be based on your aesthetic preferences, long-term maintenance commitment, and budget. For a smooth, budget-friendly, classic finish, plaster may be the ideal choice. But for those seeking a durable, natural-looking, and low-maintenance pool surface, a pebble finish is an excellent choice.
