Importance of Maintaining Pool Surfaces

Your pool's surface plays a crucial role in maintaining water quality and preventing leaks. Over time, exposure to harsh chemicals, UV rays, and regular use can cause the plaster to deteriorate, leading to a variety of issues.

What is Pool Plaster Refinishing?

Pool plaster refinishing involves resurfacing the interior of your pool with a fresh layer of plaster or finish. This not only restores the appearance of your pool but also helps to seal and protect the underlying structure.

Signs Your Pool Needs Refinishing

Fading or Discoloration

One of the most obvious signs that your pool needs refinishing is a faded or discolored appearance. This is often caused by prolonged exposure to sunlight and chemicals, resulting in a dull or uneven color.

Cracks and Chips

Cracks and chips in the plaster are not only unsightly but can also lead to water loss and structural damage if left untreated. These issues are commonly caused by fluctuations in temperature, ground movement, or improper installation.

Rough Texture

If the surface of your pool feels rough or abrasive to the touch, it may be a sign that the plaster is deteriorating. This can make swimming uncomfortable and may indicate the need for refinishing.

What Are The Types of Pool Plaster?

White Plaster

White plaster is the most common type of pool finish and provides a classic, clean look. It is affordable and can last for many years with proper maintenance.

Exposed Aggregate

Exposed aggregate plaster contains small stones or pebbles embedded in the surface, creating a textured appearance. This type of plaster is durable and offers a unique aesthetic.

Colored Plaster

Colored plaster allows you to customize the look of your pool with a wide range of hues to choose from. It can add depth and dimension to your pool's design but may require more frequent maintenance to preserve its color.

Steps Involved in Pool Plaster Refinishing

Drain and Clean the Pool

Before refinishing can begin, the pool must be drained and thoroughly cleaned to remove debris, algae, and other contaminants.

Repair Any Surface Damage

Any cracks, chips, or other surface damage should be repaired prior to applying the new plaster or finish to ensure a smooth and uniform surface.

Apply New Plaster or Finish

Once the surface is prepped, the new plaster or finish can be applied using specialized tools and techniques to achieve the desired result.

Cost Factors to Consider

Size and Shape of the Pool

The size and shape of your pool will have a significant impact on the overall cost of refinishing. Larger pools or those with complex designs may require more materials and labor.

Type of Plaster Chosen

The type of plaster or finish you choose will also affect the cost. While basic white plaster is typically the most affordable option, upgrades such as colored plaster or exposed aggregate will come at a higher price.

Additional Repairs Needed

If your pool requires any additional repairs, such as plumbing or structural work, this will add to the overall cost of the project.

Benefits of Pool Plaster Refinishing

Enhanced Aesthetics

Refinishing your pool can dramatically improve its appearance, making it look brand new again and enhancing the overall aesthetics of your outdoor space.

Increased Durability

Fresh plaster or finish provides a protective barrier against damage, helping to extend the lifespan of your pool and reduce the need for frequent repairs.

Improved Pool Health

A smooth, properly sealed surface is easier to clean and maintain, reducing the risk of algae growth and improving water quality.

DIY vs. Professional Refinishing

Pros and Cons of Each Option

While DIY pool plaster refinishing may seem like a cost-effective option, it requires specialized knowledge and equipment to achieve professional results. Hiring a professional ensures a high-quality finish and reduces the risk of mistakes.

Safety Considerations

Working with pool chemicals and equipment can be dangerous, especially for inexperienced individuals. Professional pool refinishers have the training and expertise to safely complete the job.

How to Choose a Pool Plaster Refinishing Contractor?

Researching Local Options

Start by researching local pool plastering companies online and asking for recommendations from friends, family, and neighbors.

Checking References and Reviews

Before hiring a contractor, be sure to check their references and read online reviews to ensure they have a reputation for quality workmanship and customer satisfaction.

Obtaining Multiple Quotes

Get quotes from several different contractors to compare prices and services before making a decision.

Maintenance Tips for Newly Refinished Pools

Proper Chemical Balance

Maintaining proper chemical balance is essential for preserving the integrity of your pool plaster and preventing damage.

Regular Cleaning and Brushing

Regularly cleaning and brushing your pool will help prevent algae growth and prolong the life of the plaster finish.

Common Mistakes to Avoid

Neglecting Minor Repairs

Ignoring minor cracks or chips in your pool plaster can lead to more extensive damage over time. Addressing these issues promptly can save you time and money in the long run.

Using Harsh Cleaning Products

Avoid using harsh cleaning products or abrasive tools on your pool plaster, as these can cause damage and premature wear.

Environmental Considerations

Eco-Friendly Plaster Options

If you're concerned about the environmental impact of traditional pool plaster, consider eco-friendly alternatives made from recycled materials or natural ingredients.

Disposal of Old Plaster

Proper disposal of old pool plaster is important to minimize environmental impact. Check local regulations for guidelines on disposal and recycling options.


Pool plaster refinishing is an essential maintenance task that can help prolong the life of your pool, enhance its appearance, and improve overall functionality. By understanding the signs that your pool may need refinishing, choosing the right type of plaster, and hiring a qualified contractor, you can enjoy a beautiful and durable pool for years to come.
