Why are Tiles Falling Off My Pool?

Jun 20

Pool damage comes in all shapes and sizes. Sometimes, it is in the form of little glass tiles surrounding your entire pool. Imagine this: you’re relaxing by your pool, enjoying the perfect summer day, when you notice something disconcerting—swimming pool tiles are starting to fall off your pool wall. This issue can be frustrating and worrisome, especially if you’re not sure what’s causing it or how to fix it.

At American Dream Pool & Spa Service, we’ve seen this problem countless times and are here to shed light on why tiles fall off pools and how you can address it.

What Causes Pool Tiles to Come Off?

For pool owners, understanding why pool tiles fall off is the first step toward prevention and repair. Several factors can contribute to this issue:

1. Water Chemistry

Improper water chemistry is one of the leading causes of tile problems. If the water is too acidic or too alkaline, it can erode the adhesive holding the tiles. Regularly testing and balancing your pool’s water chemistry is crucial to maintaining the integrity of your tiles.

2. Poor Installation

If the tiles were not installed correctly, they are more likely to fall off. This could be due to using the wrong type of adhesive, not allowing adequate curing time, or not preparing the surface properly before installation.

3. Environmental Factors

Extreme temperatures and freeze-thaw cycles can cause tiles to expand and contract, leading to loosening over time. Pools in areas with significant temperature fluctuations are more prone to this issue.

4. Structural Movement

Any movement in the pool structure, such as settling or shifting, can cause tiles to detach. This is often a sign of underlying structural issues that need to be addressed.

5. Aging Materials

Over time, the materials used in pool construction can degrade. Adhesives lose their bonding power, and the tiles themselves may become brittle and crack. This can happen to mosaic tiles, ceramic tiles, and glass tiles alike.

How to Prevent Pool Tiles from Falling Off?

Prevention is always better than cure. Here are some proactive measures to keep your pool tiles intact:

1. Regular Maintenance

Consistent maintenance is key to preventing tile problems. Regularly check the condition of your tiles and grout, and address any issues immediately.

2. Balanced Water Chemistry

Maintain proper water chemistry by regularly testing and adjusting the pH, alkalinity, and calcium hardness levels. This helps prevent the water from becoming corrosive.

3. Quality Installation

Ensure that your tiles are installed by experienced professionals using the appropriate materials and techniques. Proper surface preparation and adhesive application are critical.

4. Use of Expansion Joints

In areas prone to temperature fluctuations, using expansion joints can help accommodate the expansion and contraction of materials, reducing the risk of tiles falling off.

5. Regular Inspections

Have a professional inspect your pool periodically for any signs of structural movement or other issues that could affect the tiles.

How Long Should Tiles Last in a Pool?

With proper installation and maintenance, pool tiles should last for many years. Generally, you can expect well-maintained pool tiles to last anywhere from 5 to 20 years. The longevity of your tiles depends on factors such as the quality of materials, environmental conditions, and how well you maintain your pool. Regular upkeep and timely repairs can extend the life of your tiles significantly.

How Do I Get My Pool Tiles to Stick?

Ensuring that pool tiles stick properly involves using the right materials and techniques. Here’s a step-by-step guide to help you get your pool tiles to adhere correctly:

1. Surface Preparation

Clean the area thoroughly to remove any dirt, debris, or old adhesive. The surface should be smooth and free of contaminants to ensure a strong bond.

2. Choosing the Right Adhesive

Use a high-quality adhesive specifically designed for underwater use. Epoxy-based adhesives are commonly recommended for pool tiles due to their strong bonding properties and resistance to water.

3. Applying the Adhesive

Apply the adhesive evenly on the back of the tile and the surface where it will be placed. Ensure that the adhesive layer is consistent to avoid air pockets.

4. Pressing the Tile

Carefully press the tile into place, making sure it is level with the surrounding tiles. Use a tile spacer if necessary to maintain even spacing.

5. Curing Time

Allow sufficient time for the adhesive to cure before exposing the tiles to water. Follow the manufacturer’s instructions regarding curing time to ensure a secure bond.

How To Fix Tiles In A Swimming Pool

If you notice tiles falling off your pool, addressing the issue promptly can prevent further damage. Here’s how you can fix loose or fallen tiles in your pool:

1. Gather Your Materials

You’ll need tile adhesive, grout, a trowel, a sponge, and replacement tiles if any are broken or missing.

2. Drain the Pool

Lower the water level below the area where the tiles need to be fixed. This provides a dry working area and ensures proper adhesion.

3. Remove Loose Tiles

Carefully remove any loose tiles and clean the area thoroughly. If the old adhesive is still present, scrape it off to create a clean surface for the new adhesive.

4. Apply New Adhesive

Spread the adhesive evenly on the back of the tile and the area where it will be placed. Press the tile firmly into place, ensuring it is level with the surrounding tiles.

5. Let the Adhesive Cure

Allow the adhesive to cure for the recommended time. This usually takes 24 to 48 hours, but it’s best to follow the manufacturer’s instructions.

6. Apply Grout

Once the adhesive is fully cured, apply grout to the gaps between the tiles. Use a grout float to press the grout into the spaces, ensuring there are no air pockets.

7. Clean Excess Grout

Use a damp sponge to wipe away any excess grout from the surface of the tiles. Rinse the sponge frequently to keep it clean.

8. Allow Grout to Cure

Allow the grout to cure for the recommended time before refilling the pool with water. This usually takes another 24 to 48 hours.

9. Refill the Pool

Once the grout has cured, refill the pool to its normal water level. Check the repaired area to ensure the tiles are secure and there are no leaks.
