What is Gunite?

Before we delve into the replastering process, let’s quickly touch upon what gunite is. Gunite is a mixture of dry cement and sand that is pneumatically sprayed onto a framework of rebar or steel mesh to create the shell of a pool. After the gunite is applied, it is sealed with plaster to provide a smooth and waterproof surface.To explore more details and considerations regarding Gunite pool, our comprehensive guide on What Are Gunite Pools – Unveiling the Wonders has you covered.

Reasons for Replastering a Gunite Pool

Over time, the plaster in a gunite pool can deteriorate due to exposure to chemicals, sunlight, and frequent use. Here are some common signs that indicate the need for replastering:

• Cracked or chipped plaster: As the pool ages, the plaster can develop cracks and chips, which not only affects the pool’s aesthetics but also makes it harder to clean.
• Stains and discoloration: Mineral deposits, algae, and chemical imbalances can cause unsightly stains and discoloration on the pool surface.
• Roughness and peeling: Worn out plaster can feel rough to the touch and may start peeling, potentially causing injuries and hindering your swimming experience.
• Leaks and water loss: If you notice a significant decrease in water level that can’t be attributed to evaporation, it could indicate leaks in the plaster that need to be addressed promptly.

How Much Does it Cost to Replaster a Gunite Pool?

The cost of re plastering a gunite pool can vary depending on several factors. Here are the key aspects to consider when determining the cost:

Factors Affecting the Cost

1. Pool Size: The size of your pool is a significant determinant of the overall cost. Larger pools require more materials and labor, hence costing more to replaster.
2. Pool Depth and Complexity: Pools with varying depths, intricate designs, or features like vanishing edges or spa areas will have higher costs as they require more expertise and effort to replaster.
3. Choice of Plaster: There are different types of plaster available, such as white plaster, colored plaster, or premium finishes like pebble or quartz. Each type has a different price point, with premium finishes being more expensive.
4. Local Labor Rates: Labor costs vary from region to region. Higher labor rates may increase the overall cost of replastering.
5. Additional Repairs: If your pool requires extensive repairs, rectifying cracks, or fixing leaks before replastering, these additional repair costs should be factored into the overall budget.

Cost Breakdown

• Average Cost Range: $5,000 – $15,000
• White Plaster: $5,000 – $7,000
• Colored Plaster: $6,000 – $8,000
• Premium Finishes (Pebble or Quartz): $9,000 – $15,000

Remember, these figures are averages, and the final cost may vary based on your specific requirements and location. It’s always best to consult with pool professionals and gather multiple quotes to get an accurate estimate.

How Often Should You Replaster a Gunite Pool?

The frequency of replastering your gunite pool depends on multiple factors, including the quality of the initial installation, maintenance practices, and the type of plaster used. On average, a gunite pool should be replastered every 10 to 15 years. However, some factors may necessitate more frequent replastering:

1. Poor Water Chemistry: Imbalances in pH levels, high calcium hardness, or inadequate water sanitation can accelerate plaster deterioration, requiring more frequent replastering.
2. Harsh Climate: Extreme heat, cold, or freeze-thaw cycles can degrade the plaster at a faster rate, warranting more regular replastering.
3. Lack of Maintenance: Neglecting regular pool maintenance, such as brushing and maintaining proper chemical levels, can lead to faster plaster degradation.

It is crucial to monitor the condition of your pool’s plaster regularly and address any signs of damage promptly to ensure its longevity.

The Difference between Resurfacing and Replastering a Pool

Many people often use the terms resurfacing and replastering interchangeably when referring to pool renovations. However, it’s important to understand the distinction between the two:

• Replastering: Replastering involves removing the existing plaster layer and applying a new layer of plaster. It is typically done to restore the pool’s smoothness and appearance.
• Resurfacing: Resurfacing goes beyond replastering and involves more extensive repairs or upgrades. It may include adding a new layer of plaster, as well as other enhancements like pebble finishes, tile work, or new decking material.

The choice between replastering and resurfacing depends on the condition of your pool, budget, and desired outcome. For minor cosmetic issues, replastering may suffice, whereas resurfacing is ideal for pools requiring additional repairs or a complete makeover.

Steps to Replaster a Gunite Pool

If you’re up for the challenge of replastering your gunite pool yourself, here is a step-by-step guide to help you through the process. Keep in mind that replastering can be a labor-intensive task, and it’s crucial to follow proper safety precautions and use appropriate materials.

Step 1: Drain the Pool
