• Outdated aesthetic (especially if you want to modernize the look)

If you notice any of these symptoms, it’s time to seriously consider resurfacing. Understanding what’s involved in the process can help you make a smart decision and budget accordingly.

Step-by-Step Process of Pool Resurfacing

Resurfacing a pool is a multi-step process that requires professional expertise, though homeowners may participate in some preparatory stages. Below is a breakdown of each key phase involved in a typical pool resurfacing job.

1. Draining the Pool

Before any resurfacing work can begin, the pool must be completely emptied. This can take anywhere from a few hours to a few days, depending on the size of the pool and the drainage system in place. Local regulations and environmental considerations must also be taken into account to ensure proper water disposal.

2. Inspection and Repair of Structural Issues

Once the pool is drained and dry, licensed technicians will inspect the shell for any structural damage such as cracks, leaks, or weak spots. These issues must be repaired before any resurfacing materials are applied to prevent future problems.

Common Repairs Include:

• Crack patching with epoxy or cementitious compounds
• Replacing damaged tiles around the waterline
• Fixing any leaks in the plumbing system

This phase ensures that the pool structure is sound and ready to support the new surface for many years.

3. Surface Preparation

The next step involves removing the old surface—whether it’s plaster, Pebble Tec, tile, or a different material. This is typically done using a chipping hammer or other heavy-duty tools. Once the existing layer is stripped away, the technicians will clean and inspect the underlying concrete shell.

Any rough or uneven areas will be sanded down, and the entire shell may be acid-washed to remove residual chemicals, oils, and surface dust. This step is crucial for ensuring proper bonding of the new surface material.

4. Selection of Resurfacing Material

Choosing the right material is one of the most important decisions in the resurfacing process. Different materials offer varying levels of durability, aesthetics, maintenance needs, and costs. The most common choices include:

• Grouting and sealing phases follow after installation.

Paint Application:

• Paint is applied in multiple coats after a surface primer and bonding agent are used.
• Epoxy paint is long-lasting and suitable for fiberglass or previously painted pools.

6. Curing and Refilling the Pool

Once the surface is applied, it must be allowed to cure properly, typically taking several days depending on the product and weather conditions. During this time, the pool shell is often kept damp or misted regularly.

After curing is complete, the pool is rinsed thoroughly and gradually filled with water to avoid pressure-related issues. Initial balancing of pool chemistry is essential to protect the new surface and ensure water safety.

7. Start-up and Water Chemistry Balancing

The start-up process involves circulating the water, cleaning the filter, and balancing chemicals to maintain clarity and prevent corrosion or staining. This usually includes:

• Adjusting pH levels (ideal range: 7.4–7.6)
• Managing calcium hardness and total alkalinity
• Chlorine or alternative sanitization adjustments

The initial few weeks after resurfacing are critical for ensuring a long-lasting, beautiful finish.

What does pool resurfacing involve?

Pool resurfacing is the process of renewing the interior surface of a swimming pool to restore its appearance, functionality, and durability. This typically involves draining the pool, repairing any structural damage such as cracks or leaks, and then applying a new finish coat. The exact process can vary depending on the type of existing surface—whether it’s plaster, pebble, tile, or vinyl—and the chosen material for the new finish. Skilled technicians will sand or acid wash the old surface to create a proper bonding surface before applying the new material.

After the resurfacing material is applied, the pool must cure for a specific period before it can be refilled and used. During this time, it’s essential to follow manufacturer guidelines and professional recommendations to ensure the longevity of the new surface. The entire resurfacing project can take anywhere from a few days to over a week, depending on the pool size and conditions. It’s a critical maintenance step that can significantly enhance the pool’s aesthetics and prevent future structural damage.

How often should a pool be resurfaced?

The frequency of pool resurfacing depends largely on the type of finish, the pool’s usage, environmental conditions, and the quality of maintenance. In general, most traditional plaster finishes require resurfacing every 7 to 10 years. However, more durable finishes such as quartz or pebble can last up to 15 years before needing replacement. Regular maintenance, balanced water chemistry, and timely repairs can extend the life of the pool surface and delay the need for resurfacing.

Additionally, signs such as roughness, discoloration, cracks, or visible wear are indicators that it may be time to resurface. Homeowners should inspect their pools annually for these issues, especially after several seasons of use. Ignoring these symptoms can lead to more extensive damage and costly repairs in the long run. Therefore, even if a pool hasn’t hit the expected time frame for resurfacing, it’s wise to act when early signs of wear appear.

Plaster is the most affordable and widely used, but it’s also more prone to staining and usually has a shorter lifespan. Quartz offers better durability and comes in a variety of colors, making it a popular upgrade.

Pebble finishes are increasingly favored for their textured appearance and longevity, often lasting over a decade. They are also more resistant to staining and chemical damage. Tile resurfacing, on the other hand, offers a luxurious look and is extremely durable, but it’s more costly and labor-intensive. It’s important to discuss these options with a professional contractor to determine the best material based on your budget, aesthetic preferences, and long-term maintenance goals.

How long does it take to resurface a pool?

The duration of a pool resurfacing project depends on several factors, including the size of the pool, the chosen resurfacing material, weather conditions, and the complexity of any repairs needed. On average, the process takes between 5 to 10 days from start to finish. The timeline includes draining the pool, conducting necessary repairs, preparing the surface, applying the new coating, and allowing sufficient curing time before refilling.

Curing time is especially critical for certain finishes like plaster or pebble, which can require up to a week of drying before the pool can be filled with water. During this period, weather conditions must be monitored carefully to protect the integrity of the finish. While some materials offer faster curing times, rushing the process can compromise the longevity and quality of the resurfacing job. Therefore, it’s essential to choose a contractor who carefully manages the timeline and keeps the project on track without sacrificing quality.

Do I need to drain the pool before resurfacing?

Yes, draining the pool is a necessary step in the resurfacing process. In order to properly prepare the existing surface and apply a new finish, all water must be removed so the interior is completely dry and accessible. Draining also allows technicians to inspect for cracks, leaks, or other structural issues that need to be repaired before the new surface is applied. However, in some cases, partial draining might be sufficient if the resurfacing is limited to certain sections of the pool.

Once the pool is drained, specialized pumps are used to remove any standing water remaining in the hydrostatic relief line. The surface is then acid-washed or sandblasted to remove contaminants and old coatings. It’s important to follow local regulations regarding the disposal of drained pool water, as it may contain chemicals harmful to the environment. Working with a licensed professional ensures the draining and preparation stages are handled safely and effectively.

What are the signs that my pool needs resurfacing?

There are several key indicators that your pool may be due for resurfacing.
