Pool sealing is the process of applying a protective layer to the surface of a swimming pool to prevent water from leaking out. In this article, we want to talk about this issue completely.
Why do we need pool sealing?
Here are some reasons why pool sealing is necessary:
- Prevents leaks: Over time, the concrete or other material used to construct a pool can crack, allowing water to seep through. Pool sealing prevents leaks and keeps the water in the pool where it belongs.
- Protects from water damage: If water leaks from a pool, it can cause damage to the surrounding area, including the foundation of your home. Pool sealing ensures that water stays where it is supposed to, protecting your property from water damage.
- Maintains water quality: A pool that leaks can be difficult to maintain and keep clean. Sealing ensures that the water stays in the pool, making it easier to maintain proper water chemistry and cleanliness.
- Saves money: Fixing leaks can be expensive, especially if they cause significant damage to your property. Pool sealing is a cost-effective way to prevent leaks and avoid costly repairs.
What are the methods for sealing a pool?
The choice of pool sealing methods depends on the pool’s condition, budget, and preference. Here are some of the most common methods for pool sealing:
- Paint: Painting the pool with a waterproof paint is the simplest and most cost-effective way to seal a pool. This method is suitable for small, old, or budget-conscious pools. However, paint may not last as long as other sealing methods, and it may require regular touch-ups.
- Epoxy: Epoxy sealers are durable and long-lasting, making them a popular choice for pool sealing. The epoxy is applied in two coats, and it creates a strong, waterproof barrier that can withstand chemicals and UV rays. However, epoxy can be expensive and requires professional application.
- Plaster: Plaster is a mixture of cement, sand, and water that is applied to the pool’s walls and floor. It creates a smooth and durable surface that can last for several years. Plaster is a popular choice for in-ground pools, but it requires professional application and can be expensive.
- Fiberglass: Fiberglass is a popular choice for pool resurfacing, but it can also be used for pool sealing. Fiberglass is a strong, waterproof material that can be applied to the pool’s walls and floor, creating a smooth and durable surface. Fiberglass is relatively expensive and requires professional installation.
- Tile: Tile is another popular option for pool sealing, and it can create a beautiful and long-lasting surface. Tile is applied to the pool’s walls and floor, creating a waterproof surface that is easy to maintain. However, tile can be expensive and requires professional installation.

What are the steps for sealing a pool?
The specific pool sealing steps can vary depending on the method used and the condition of the pool. However, here are some general steps that may be involved in pool sealing:
- Drain the pool: The first step in pool sealing is to drain the pool completely. This allows for a thorough inspection of the pool’s walls and floor and ensures that the sealing material can be applied evenly.
- Clean the pool: Once the pool is drained, it is important to clean the pool thoroughly to remove any dirt, debris, or algae that may have accumulated. This helps ensure that the sealing material adheres properly to the pool’s surface.
- Repair cracks or damage: If there are any cracks or damage to the pool’s walls or floor, they must be repaired before sealing. This may involve patching the cracks or replacing damaged tiles or plaster.
- Apply the sealing material: The sealing material is applied to the pool’s walls and floor according to the manufacturer’s instructions. This may involve brushing, rolling, or spraying the material onto the pool’s surface. Depending on the material used, multiple coats may be required.
- Allow the material to cure: Once the sealing material is applied, it must be allowed to cure according to the manufacturer’s instructions. This may take several days or weeks, depending on the material used.
- Refill the pool: Once the sealing material is cured, the pool can be refilled with water. It is important to monitor the water chemistry to ensure that it is balanced and safe for swimming.
What is the best sealant used in pool sealing?
The best pool sealing material depends on several factors that you or your contractor choose. Here are some popular sealants used for pool sealing:
- Epoxy
- Plaster
- Fiberglass
- Tile
Where is the most common leak in pools?
It is important to identify and repair leaks as soon as possible to prevent damage to the pool and surrounding area. The most common leak location in pools is at the plumbing fittings, including the skimmer, return jets, and pool lights.
Other common areas where leaks can occur include:
- Cracks in the pool’s walls or floor: Cracks can develop in the pool’s concrete or other materials, allowing water to seep through.
- Vinyl liner: Vinyl liners can develop holes or tears, allowing water to leak out of the pool.
- Tile and grout: Tiles and grout can crack or become loose, allowing water to seep through.
- Skimmer basket: Leaks can occur in the skimmer basket or lid, allowing water to leak out of the pool.
- Pump and filter system: Leaks can occur in the pump and filter system, allowing water to leak out of the pool.
How long does it take to seal a pool?
The time it takes to seal a pool can vary depending on several factors, including the size of the pool, the type of sealant used, the condition of the pool, and the weather conditions. In general, pool sealing can take anywhere from a few days to a few weeks to complete, depending on the method used and the size and condition of the pool.

How much does it cost to seal a pool?
The cost to seal a pool can vary widely depending on several factors, including the size of the pool, the type of sealant used, the condition of the pool, and the location. Here are some general guidelines for the cost of pool sealing:
- Paint: Applying a paint sealant to a pool is typically the most affordable option, with costs ranging from $500 to $1,500 for an average-sized pool.
- Epoxy: Applying an epoxy sealant to a pool is more expensive than paint, with costs ranging from $5,000 to $10,000 for an average-sized pool.
- Plaster: Applying a plaster sealant to a pool is typically more expensive than epoxy, with costs ranging from $8,000 to $15,000 for an average-sized pool.
- Fiberglass: Applying a fiberglass sealant to a pool is typically the most expensive option, with costs ranging from $10,000 to $20,000 for an average-sized pool.
How often does a pool need sealing?
The frequency of pool sealing depends on several factors, including the type of pool, the quality of the original sealant, and the level of maintenance. Here are some general guidelines for how often a pool may need sealing:
- Paint: Painted pool surfaces typically need to be resealed every 3 to 5 years, depending on the quality of the paint and the level of use.
- Epoxy: Epoxy-sealed pool surfaces can last up to 10 years before needing to be resealed, depending on the quality of the epoxy and the level of use.
- Plaster: Plastered pool surfaces can last up to 15 years before needing to be resealed, depending on the quality of the plaster and the level of use.
- Fiberglass: Fiberglass-sealed pool surfaces can last up to 25 years before needing to be resealed, depending on the quality of the fiberglass and the level of use.
