Pool Replastering: When, Why, and How to Do It

Swimming pools are a fantastic addition to any home. They provide endless hours of fun and relaxation. However, maintaining them goes beyond skimming leaves and balancing chemicals.

One crucial aspect that often gets overlooked is replastering. Over time, the plaster in your pool can wear down, leading to a host of issues affecting both its look and functionality.

Replastering your pool is more than a facelift. It strengthens your pool’s structure, prevents leaks, creates a smoother surface for safe swimming, and even simplifies cleaning.

This guide dives into the importance of replastering, taking you through the process, costs, and benefits to keep your pool in top shape for years to come.

What Is Pool Plastering?

Pool plastering is essential in the construction and maintenance of swimming pools. It involves applying a smooth, strong layer of plaster to the interior surfaces of a pool to make them watertight. This process improves the pool’s appearance, protects the structure, and ensures the pool is safe and enjoyable for use.

Several types of plaster finishes are used in pools, each offering unique benefits.

Standard Plaster

Often referred to as marcite, standard plaster is a mix of white cement and crushed marble. It is the most affordable choice and provides a classic, smooth white finish.

However, it has a shorter lifespan than more advanced materials and may require more frequent maintenance.

Quartz Plaster

This type of plaster includes quartz aggregates mixed with white cement, offering superior durability and aesthetics. Quartz finishes come in various colors and can last longer than standard plaster due to their resistance to chemical etching and staining.

Pebble Plaster

Also known as pebble tec, this finish incorporates smooth river pebbles into the plaster, creating a highly durable and visually appealing surface. Pebble plaster is resistant to stains, chemicals, and algae and offers an elegant and slip-resistant textured appearance.

Getting Ready to Replaster Your Pool

For a flawless, long-lasting replastering job, meticulous preparation is key.

Here are the important steps before applying the new plaster to ensure optimal adhesion and a stunning finish that endures.

Drain Your Pool and Manage Ground Pressure

Preparation begins with completely draining your pool. Submerge a pump at the deepest part of the pool and connect it to a hose leading to an appropriate drainage area. Turn the pump on and wait for the pool to empty entirely. Use a wet-dry vacuum or manual methods for any remaining water.

While draining, it’s essential to manage hydrostatic ground pressure by opening the hydrostatic relief valves at the bottom of the pool. This prevents structural damage caused by ground pressure pushing against the empty pool.

Prep the Pool Surface for the New Plaster

Once your pool is empty and ground pressure is managed, the next step is surface preparation. Using chisels, hammers, or grinders, remove all loose or damaged plaster.

Make sure you’re thorough, as remnants can affect the adherence of the new plaster. Once cleared, sweep and clean the pool surface to remove dust and debris. The surface should be free of imperfections to ensure the new plaster adheres well.

Acid Wash the Pool Surface

Acid washing is a vital step to remove lingering stains and debris from the pool surface for a pristine base. However, safety precautions are crucial. Always wear gloves, goggles, and a mask and ensure good ventilation in the work area.

For the acid wash, mix the muriatic acid with water, generally in a 1:1 ratio, in a plastic watering can. Apply the acid mixture to the pool surface, letting it etch the surface for a few minutes. Rinse thoroughly with water to remove all acid residue. Finally, neutralize any remaining acid with a dedicated solution and rinse again.

Apply a Bond Coat for Strong Adhesion

The final step is putting a bond coat to ensure the new plaster adheres properly. The bond coat acts as a primer for the new plaster, improving adhesion.

Use a roller or sprayer to apply the bond coat evenly across the entire pool surface. Let it dry completely according to the manufacturer’s recommendations before replastering.

A Simple Guide to Replastering Your Pool

Though pool replastering might seem intimidating, following these steps and investing some patience will reward you with a stunning and durable finish that revitalizes your pool.

Applying the Plaster

Achieving a smooth, long-lasting pool finish requires meticulous replastering. Let’s break down each step of this critical process.

Preparation

Before putting the new plaster, achieve a flawless, uniform finish by meticulously cleaning the pool surface. Thoroughly sweep and hose down the pool’s surface to remove dust, dirt, and any leftover debris from the preparation process. Make sure the surface is damp, but not overly wet, for optimal plaster application.

Application Process

With the surface clean, it’s time to mix the plaster. Follow the manufacturer’s instructions carefully to achieve a smooth, creamy consistency.

Using a trowel, coat the plaster evenly across the entire pool surface, working from the bottom up. Ensure each layer is applied smoothly and evenly to avoid creating air pockets or uneven surfaces.

Smoothing and Curing

After applying the plaster, smooth it out to achieve a uniform finish. Use a trowel to eliminate imperfections and create an even surface that looks professional and feels smooth.

Once you’ve achieved the desired finish, allow the plaster to cure completely according to the manufacturer’s recommendations to ensure the plaster sets correctly and achieves maximum durability.

Filling and Treating Your Pool

After plastering, properly filling and treating your pool is paramount to protect your new surface and achieve optimal water quality.

Filling the Pool

Once the plaster has cured, you can begin filling the pool. This process should be done slowly to avoid disturbing the new surface.

Use a hose to start filling from the deep end, and let the water gradually rise. Avoid high-pressure streams that could potentially damage the freshly applied plaster.

Water Treatment

After pool filling, the next step is to balance the water chemistry. Adjust the pH, alkalinity, and calcium hardness levels to ensure the water is safe and comfortable for swimmers.

Proper water chemistry also preserves the new plaster. Test the water frequently during this initial period to make necessary adjustments and achieve balanced chemistry.

Initial Use

You might be eager to dive into your newly replastered pool, but patience is key. Follow recommended waiting times to ensure the plaster has fully set and the water chemistry is balanced. This period may involve further adjustments to keep optimal conditions for a perfect swim.

Maintaining Your Pool After Replastering

Ongoing maintenance is crucial to preserving the pristine condition of your newly replastered pool and maximizing its lifespan.

Regular Maintenance

To keep your newly replastered pool looking great, regular maintenance is key. For the first week, brush the pool walls and floor daily to remove any plaster dust that may have settled. This also helps prevent algae buildup.

Water Chemistry

Balanced water chemistry is your new plaster’s best friend. Regularly test and adjust pH, alkalinity, and calcium hardness regularly to maintain optimal levels. Frequent monitoring ensures a healthy pool environment and maximizes the lifespan of your stunning new surface.

Long-Term Care

For lasting enjoyment, prioritize the long-term care of your pool. Regularly cleaning the filters helps maintain smooth water flow and filtration, while professional inspections can catch potential issues before they become major problems.

By staying diligent with long-term care, you can enjoy a beautiful and functional pool for many years.
