Having Your Pool Replastered Guide

If you’re lucky enough to have a swimming pool in your backyard, then you already know how much joy it can bring to your life. From cooling off in the summer heat to hosting pool parties with friends and family, your pool is likely a centerpiece of your outdoor space. But like anything that sees regular use, swimming pools require maintenance over time. One of the most important parts of that maintenance is replastering the pool when the surface begins to show signs of wear and tear.

Replastering is an essential task that revitalizes your pool, giving it a fresh, smooth surface that not only looks great but also improves the pool’s longevity and safety. In this blog, we’ll dive into everything you need to know about getting your pool replastered, including when to do it, why it’s important, the process involved, and the benefits of having a newly replastered pool.

What Is Pool Replastering?

Pool replastering involves applying a new layer of plaster to the interior surface of the pool. Over time, the plaster can become rough, discolored, cracked, or even start to chip away. The purpose of replastering is to restore the smooth, waterproof layer that protects the pool’s structure and ensures the surface is safe for swimmers.

Most residential swimming pools are initially plastered with a layer of gunite or concrete, covered with a plaster coating that provides a smooth finish. Over time, however, the constant exposure to chemicals, UV rays, and fluctuating water temperatures can cause the plaster to deteriorate.

Signs That Your Pool Needs Replastering

If you’re wondering whether it’s time to replaster your pool, here are some common signs to look out for:

  1. Rough Texture: One of the most noticeable signs is when the pool surface starts to feel rough to the touch. If you or your swimmers are noticing scrapes or discomfort from the pool surface, it may be time for a new plaster layer.
  2. Discoloration: Over time, the pool’s plaster can lose its bright white or blue hue and become discolored due to mineral stains, algae, or chemical imbalances. While some stains can be cleaned, persistent discoloration is a sign that the plaster is wearing out.
  3. Cracks and Chips: Cracks in the pool’s plaster can not only be unsightly but can also indicate underlying structural issues. If left untreated, these cracks can expand, leading to more serious damage that could require costly repairs.
  4. Water Leaks: While leaks can sometimes be caused by plumbing or structural issues, cracks in the plaster can also be a source of water loss. If your pool is losing water faster than normal and you’ve ruled out other possibilities, it’s possible that deteriorating plaster is to blame.
  5. Increased Chemical Usage: As the plaster surface ages and becomes more porous, it can make it harder to maintain proper chemical balance in the pool. If you’re using more chemicals than usual to keep the water clean and clear, it may be a sign that your pool needs replastering.

Why Replastering Your Pool Is Important

Replastering is more than just a cosmetic upgrade for your pool; it plays a crucial role in maintaining its structural integrity, safety, and efficiency. Here’s why replastering is important:

  1. Extend the Life of Your Pool: The plaster layer serves as a protective barrier for your pool’s structure. Over time, if cracks or chips develop in the plaster, water can seep through and cause damage to the underlying concrete or gunite, which can be more costly to repair. By replastering your pool on time, you can avoid these larger structural problems and extend the life of your pool.
  2. Improve Swimmer Safety: Rough, chipped, or cracked plaster can be uncomfortable and even hazardous for swimmers, causing scrapes, cuts, or other injuries. A freshly plastered pool provides a smooth, safe surface that’s enjoyable for everyone.
  3. Maintain Water Balance: As mentioned earlier, deteriorating plaster can make it difficult to maintain proper chemical levels in your pool. This leads to increased chemical costs and more frequent maintenance. Replastering helps restore the smooth, non-porous surface, which reduces the amount of chemicals needed to keep the water balanced.
  4. Aesthetic Appeal: A worn-out pool surface can make your entire backyard look tired and neglected. Replastering gives your pool a fresh, bright appearance, enhancing your backyard’s overall visual appeal.

The Pool Replastering Process

Replastering a pool is a complex process that should always be handled by professionals. Here’s a step-by-step breakdown of what you can expect during the replastering process:

  1. Draining the Pool

The first step in the replastering process is to drain the pool completely. This allows the professionals to access the pool’s surface and prepare it for the new layer of plaster. Before draining the pool, it’s important to check with local regulations to ensure proper disposal of the pool water.

  1. Preparing the Surface

Once the pool is drained, the next step is surface preparation. This involves chipping away any loose, damaged plaster and thoroughly cleaning the pool’s interior to remove dirt, algae, and other contaminants. In some cases, an acid wash may be used to remove stains and ensure the new plaster adheres properly.

  1. Applying the New Plaster

After the surface has been prepped, the new plaster is applied. The plaster is typically a mix of cement, water, and either marble dust or other aggregates, depending on the desired finish. The new layer is spread evenly across the entire pool surface, including the walls and floor. This is a precise process that requires skill and experience to ensure a smooth, even finish.

  1. Curing the Plaster

Once the new plaster has been applied, the pool must be refilled with water to begin the curing process. It’s important to fill the pool immediately to prevent the new plaster from drying out and cracking. The curing process can take up to a few weeks, during which time the water chemistry must be carefully monitored to ensure the plaster hardens correctly.

  1. Balancing the Water Chemistry

After the pool is refilled, it’s crucial to maintain proper water chemistry. The pH, alkalinity, and calcium hardness levels must be monitored and adjusted to ensure the new plaster cures properly. During this time, it’s also important to brush the pool’s surface regularly to remove any plaster dust and help the curing process.

How Often Should You Replaster Your Pool?

On average, pool plaster lasts about 10 to 15 years, depending on factors like the quality of the original plaster, pool usage, and water chemistry. However, heavy use, poor maintenance, or improper chemical balance can cause plaster to deteriorate more quickly, requiring replastering sooner.

If you’ve noticed signs of wear in your pool’s plaster, it’s best not to delay the repair process. Ignoring these signs can lead to more significant issues, which could require expensive repairs down the line.

Conclusion: Replastering for a Better Pool Experience

Replastering your pool is an essential part of keeping it in great shape, both aesthetically and functionally. Whether you’ve noticed cracks, discoloration, or rough patches, getting your pool replastered will restore its smooth surface and protect its structural integrity for years to come.

Investing in a pool replastering project not only enhances your pool’s appearance but also ensures a safe and enjoyable experience for swimmers. A well-maintained pool is a centerpiece for relaxation, exercise, and entertainment, and replastering ensures that your backyard oasis remains a source of joy for you and your family for years to come.
