How Long Does Plaster Pool Finish Last?

Pool plaster lasts around 7 to 10 years, depending on factors such as water chemistry, maintenance, and weather exposure. Plaster finishes are different from most finishes in terms of their durability and longevity.

Factors That Affect the Lifespan

Several elements can change how long a plaster pool finish lasts. Understanding these factors helps maintain the pool’s look and function for as long as possible.

  1. Water Chemistry – Keeping the water chemistry balanced is crucial. High acidity or alkalinity levels can erode or damage the plaster, reducing its lifespan.
  2. Usage Frequency – Pools that see a lot of action may need replastering more often. High foot traffic can wear down the surface quicker.
  3. Weather Conditions – Extreme weather like intense heat, cold, or constant exposure to sunlight can affect plaster durability over time.
  4. Maintenance Routine – Regular cleaning and maintenance prevent algae growth and staining, which can otherwise penetrate and weaken plaster.
  5. Quality of Plaster Material – Higher quality plaster materials tend to last longer than their cheaper counterparts because they are more resistant to wear and tear.
  6. Pool Chemicals – Correctly using pool chemicals protects the surface. Incorrect use or overuse of chemicals can lead to plaster degradation.
  7. Type of Water – Saltwater pools may have different effects on plaster compared to chlorine pools, as salt can be more corrosive over time.
  8. Curing Process – Properly curing new pool plaster according to manufacturer guidelines ensures it sets correctly for lasting durability.
  9. Professional Installation – A skilled professional ensures the plaster adheres properly and evenly, preventing premature aging or cracking.
  10. Surrounding Landscape – Trees and plants too close to the pool can lead to debris accumulation and stain the plaster, affecting its lifespan.

Monitoring these factors closely will help extend your pool finish’s life, ensuring many years of enjoyable swimming experiences without frequent replastering needs.

Differences between plaster and pebble

Understanding the differences between the lifespan of plaster finishes and the lifespan of pebble finishes is crucial for pool owners. Each type has its unique characteristics and benefits.

Finish TypeDescriptionLifespanMaintenance Level
PlasterA mixture of cement, sand, water, and sometimes colorant. Offers a smooth classic look.5-10 yearsHigh
PebbleConsists of small pebbles embedded in a cement or polymer base. Provides a natural, textured appearance.15-20 yearsModerate

These finishes differ not only in appearance but also in longevity and the effort required to keep them looking their best. Choosing the right one depends on personal preferences, budget, and willingness to maintain it.

Maintaining Your Pool Finish

Maintain your pool finish by regularly brushing and vacuuming to prevent buildup, and ensure proper water chemistry to avoid scale or staining. Curing your new plaster surface is crucial for its longevity, so follow the recommended curing process meticulously.

Proper maintenance tips to prolong the life of your pool finish

To extend the life of your pool finish, follow these tips:

  1. Keep the pH levels balanced within the recommended range to prevent damage to the plaster surface.
  2. Regularly brush and vacuum the pool to remove dirt, algae, and other contaminants that can degrade the finish.
  3. Use a pool cover when the pool is not in use to protect it from environmental factors such as sun exposure and debris.
  4. Schedule routine professional maintenance and inspections to identify issues early and address them promptly.
  5. Avoid draining the pool frequently as it can cause stress on the finish, leading to premature deterioration.
  6. Be cautious with chemical usage and consult with a professional if you are unsure about proper application or dosage.
  7. Consider applying a sealant or protective coating to enhance the durability of the plaster finish against wear and tear.

The importance of curing your new plaster surface

Curing your new plaster surface is crucial for ensuring its longevity. Properly curing the surface helps prevent cracks and imperfections, promoting a more durable finish. Consistent watering or misting over several days after the initial set is essential to achieve this.

This process allows the plaster to properly hydrate, resulting in a stronger and more resilient pool surface that can better withstand exposure to chemicals and fluctuations in temperature.

It’s important not to rush or neglect the curing process, as it directly impacts the overall lifespan of your pool finish. Taking the time to cure your new plaster surface will pay off in terms of durability and longevity.

When to Replaster Your Pool

It’s essential to recognize signs indicating it’s time for pool replastering. Different types of finishes have varying lifespans, so be vigilant about the condition and age of your pool surface.

Signs that it’s time to replaster

  • Cracks and fissures develop on the pool surface, indicating structural wear and tear.
  • The plaster becomes rough to the touch, potentially causing injury or discomfort to swimmers.
  • Stubborn stains appear that cannot be removed with regular cleaning, detracting from the pool’s aesthetic appeal.
  • A significant loss of material occurs, visibly thinning the plaster layer.
  • The pool finish loses its color vibrancy and appears faded, signaling degradation.

Average lifespan of different types of finishes

Plaster pool finishes typically last around 7-10 years, while quartz finishes have a longer lifespan of about 12-20 years. ecoFINISH offers a lifespan of up to 10 years or more. Its durability and chemical resistance benefits make it a compelling choice for homeowners. Epoxy coatings can provide excellent durability, with some formulations lasting up to 7 to 10 years before needing recoating.

Factors such as maintenance, water chemistry, and exposure to the elements can impact the longevity of your pool finish. Understanding these differences can help you make an informed decision when selecting a finish for your pool.


Maximizing the lifespan of your plaster pool finish involves regular maintenance. Caring for your pool surface, including proper curing and maintenance, is key to extending its durability.

Regular inspections can help you identify when it’s time for a replastering job. Understanding these factors will allow you to enjoy your pool for longer periods without needing frequent renovations.
