Is it possible to Repair osmotic blistering in a fiberglass pool?

Osmotic blistering in a fibreglass pool is a result of water absorption into the fibreglass laminate. This can be caused by a number of factors, including:

- Poor water chemistry: High levels of chlorine, bromine, or pH can damage the fibreglass laminate and make it more susceptible to water absorption.

- Inadequate drainage: If water is allowed to pool around the pool, it can seep into the fibreglass laminate and cause blistering.

- Structural damage: Cracks or other damage to the pool shell can allow water to enter and cause blistering.

Repairing osmotic blistering in a fibreglass pool can be a complex and time-consuming process. It typically involves:

- Draining the pool and allowing it to dry completely.

- Removing the damaged fibreglass laminate.

- Repairing the damaged area with a new layer of fibreglass.

- Re-gelcoating the pool.

It is important to note that repairing osmotic blistering in a fibreglass pool is not always successful. In some cases, the blistering may be too extensive or the damage may be too deep to repair properly. If the blistering is severe, it may be necessary to replace the entire pool liner.

If you are experiencing osmotic blistering in your fibreglass pool, it is important to contact a qualified pool professional to assess the damage and recommend the best course of action.
