Comprehensive Guide to Plaster of Pool: Everything You Need to Know for Perfect Pool Finishes

May 5, 2025

When it comes to creating a stunning, durable, and long-lasting swimming pool, the choice of surface finish plays a pivotal role. Among the many options available, pool plastering remains a widely favored method for its classic appearance, cost-effectiveness, and proven performance. In this comprehensive guide, we will delve into the intricacies of plaster of pool, demystify common misconceptions, and provide expert insights to help you make informed decisions about your swimming pool project.

Understanding the Role of Pool Plaster: The Foundation of Your Pool’s Aesthetic and Durability

What Is Pool Plaster?

Pool plaster is a cement-based mixture applied to the interior surface of a swimming pool. It forms a smooth, durable coating that provides the pool with a sleek, polished appearance. Over time, it becomes an integral part of the pool structure, offering both functional and aesthetic benefits. The term “plaster of pool” is sometimes misused, but the correct terminology is “pool plaster,” which correctly describes this essential finishing material.

Importance of Quality Pool Plaster

A high-quality pool plaster not only enhances the visual appeal but also directly impacts the longevity and maintenance of the pool. Properly applied plaster resists chemical deterioration, prevents water leakage, and maintains its aesthetic appeal for many years. Conversely, inferior plaster or improper installation can lead to issues such as cracking, chipping, or scaling, which can be costly to repair and diminish your pool's value.

Types of Pool Plaster: Choosing the Right Finish for Your Pool

Traditional White Plaster

The most common type, white plaster, offers a clean, classic look with a smooth finish. It is budget-friendly and straightforward to apply but may require more frequent maintenance to retain its pristine appearance.

Colored Plaster

Colored plaster options include shades like blue, tan, or stained finishes, which can dramatically alter the pool's look, making it more personalized and visually appealing. These options often involve blended dyes or mineral aggregates for unique aesthetics.

Quartz and Pebble Finishes

For homeowners seeking luxury and durability, quartz finishes incorporate quartz aggregates that provide increased strength and chemical resistance. Similarly, pebble finishes use small natural stones embedded within the plaster for a textured, high-end appearance that lasts longer and requires less maintenance.

Exposed Aggregate

This technique exposes fragments of aggregate within the plaster, creating a rugged, textured surface that offers excellent slip resistance and visual interest. It is ideal for aesthetic appeal and longevity.

The Step-by-Step Process of Applying Pool Plaster

1. Surface Preparation

Thorough cleaning of the existing surface to remove debris, oils, and old plaster residue.
Repair of any cracks, chips, or structural issues to ensure a stable base.
Water testing to confirm proper submersion level and leak prevention prior to plastering.

2. Application of Bonding Agents

Special bonding agents are applied to improve adhesion between the existing base and the new plaster overlay, ensuring longevity and reducing the risk of delamination.

3. Mixing the Plaster

The plaster mix, typically a blend of Portland cement, lime, fine sand, water, and optional additives or colorants, is prepared to manufacturer specifications for optimal consistency and strength.

4. Application of the Plaster

Skilled technicians apply the mixture evenly across the surface using trowels.
The plaster is carefully floated and smoothed to achieve a uniform finish.
Additional layers or decorative finishes, such as quartz or pebble, are embedded as per the selected design.

5. Curing and Finishing

Proper curing by maintaining moist conditions prevents cracks and enhances strength. After curing, the surface may be brushed or sealed to achieve the desired texture and gloss.

Factors Influencing the Success of Pool Plastering

Quality of Raw Materials

Premium ingredients result in a more durable, resistant surface. High-quality sand, cement, and colorants are essential for longevity and aesthetic appeal.

Skill of the Installation Team

Experienced, certified installers ensure proper mixing, application, and curing processes that prevent common problems like cracking, scaling, or delamination.

Environmental Conditions

Temperature, humidity, and even water chemistry influence the curing process and the final quality of the plaster. Proper scheduling and environmental control are critical during installation.

Common Problems with Pool Plaster and How to Prevent Them

Cracking

Caused by improper curing, structural movement, or poor material quality.
Prevention involves proper preparation, mixing, and curing techniques, along with regular maintenance.

Scaling and Chalkiness

Surface deterioration due to chemical imbalance or water that is too aggressive.
Ensure proper water chemistry, regular cleaning, and sealing to mitigate this issue.

Discoloration or Staining

Can result from mineral deposits, algae growth, or chemical reactions.
Regular cleaning, water testing, and sealing extend the lifespan and maintain appearance.

Maintaining and Repairing Your Plaster of Pool

Routine Maintenance

Regular brushing to prevent algae buildup and stains.
Maintaining proper chemical levels (pH, alkalinity, sanitizer levels).
Periodic sealing or refinishing for aesthetic rejuvenation.

Repairing Damaged Plaster

If your pool plaster exhibits cracks, chips, or scaling, professional repair is essential. Repair methods include patching small cracks or complete relining for more extensive damage. Addressing issues early prevents costly repairs and extends the life of your pool.
