Gunite pools, known for their durability, can still succumb to the elements over time. Cracks, stains, and general wear and tear can diminish their beauty and functionality. Resurfacing offers a cost-effective way to restore your pool's luster and extend its lifespan. This guide provides a detailed look at how to resurface a gunite pool.

Assessing Your Gunite Pool: The First Step

Before you begin resurfacing, a thorough assessment is crucial. This involves identifying the extent of damage and choosing the appropriate resurfacing method.

Identifying the Damage

Cracks: Small cracks might only need patching, while larger ones require more extensive repair.
Stains: Determine the source of stains (minerals, algae) to choose the right cleaning and prevention methods.
Scaling or Peeling: This indicates a problem with the existing surface that needs addressing before resurfacing.
Exposed Aggregate: If the aggregate is showing through, this points to significant wear and tear.

Choosing a Resurfacing Method

Several options exist for resurfacing gunite pools:

Plaster: A classic choice, offering a smooth, durable finish. It's relatively affordable but requires more skill to apply properly.
Quartz: This offers a more durable and non-porous surface than plaster, reducing staining and algae growth. It comes in a variety of colors.
Pebble Tec or similar: These surfaces create a textured finish, offering a unique aesthetic and excellent slip resistance. They are very durable.

Consult with pool professionals to determine the best option for your pool and budget. They can assess your specific damage and advise accordingly.

Preparing Your Gunite Pool for Resurfacing

Proper preparation is key to a successful resurfacing project. This stage involves cleaning, repairing, and prepping the surface.

Thorough Cleaning

Remove all debris, algae, and loose plaster from the pool's surface. This may require specialized cleaning solutions and equipment. Power washing is often necessary. A truly clean surface ensures proper adhesion of the new finish.

Repairing Damages

Address any cracks, holes, or other damage before resurfacing. This might involve using specialized patching compounds or epoxy resins for larger repairs. Ensure all repairs are completely dry before proceeding.

Acid Washing (Often Necessary)

Acid washing removes any remaining old finish or residue, leaving a clean surface for optimal adhesion. Always follow the manufacturer’s instructions carefully when using acid. Protective gear is essential.

The Resurfacing Process: A Step-by-Step Guide

Once your pool is prepared, you can begin the resurfacing process. While DIY is possible for minor repairs, most people hire professionals for a complete resurfacing job.

Step 1: Applying the Resurfacing Material

The application method varies depending on the chosen material (plaster, quartz, pebble). Professionals typically use specialized tools and techniques to ensure even distribution and optimal adhesion.

Step 2: Curing and Finishing

After application, the new surface requires time to cure properly. This process can take several days or even weeks, depending on the material and weather conditions. During curing, avoid disturbing the surface. Once cured, a final cleaning might be necessary.

Step 3: Filling and Balancing the Pool

After curing, refill your pool with water and balance its chemistry. This is critical to ensure the longevity of your resurfaced pool and prevent future problems. Regular chemical maintenance is essential after resurfacing.

Post-Resurfacing Maintenance

Maintaining your newly resurfaced pool is vital to preserving its beauty and longevity. Regular cleaning, chemical balancing, and preventative measures can keep it looking great for years.

Regular Cleaning: Brush the pool walls and floor regularly to remove debris and prevent staining.
Chemical Balancing: Maintain proper pH and alkalinity levels to prevent scaling and corrosion.
Preventative Measures: Consider using pool covers to minimize debris and reduce chemical consumption.

Choosing a Professional: Important Considerations

While some DIY repairs are possible, full resurfacing is often best left to professionals. Experienced contractors possess the necessary expertise, equipment, and materials to deliver excellent results. Look for reputable contractors with a proven track record and positive customer reviews.

Resurfacing your gunite pool is a significant investment, but it can dramatically enhance its appearance and extend its useful life. With careful planning and execution, your pool will be sparkling again. Remember, consulting with professionals early in the process is highly recommended. They can guide you through the best choices for your specific needs and budget, ensuring a successful project and years of enjoyment.
