1. Draining the Pool
The first step is to drain the pool completely. This will make it easier and safer to work on the repairs.
2. Removing the Damaged Gunite
Once the pool is drained, the damaged gunite can be removed. This can be done using a jackhammer or other suitable tool.
3. Preparing the Surface
The surface of the pool where the damaged gunite has been removed must be prepared for the new gunite to be applied. This involves cleaning and smoothing the surface to ensure a good bond.
4. Applying New Gunite
New gunite is then applied to the prepared surface. The gunite is applied in layers, with each layer being allowed to dry before the next layer is applied.
5. Curing the Gunite
Once all of the gunite has been applied, it must be allowed to cure. This typically takes several days.
6. Filling and Testing
Once the gunite is cured, the pool can be filled with water and tested to ensure that the repairs are successful.
7. Resurfacing
After the pool has been filled and tested, the surface can be resurfaced to improve its appearance and durability. This can be done using a variety of materials, such as plaster, tile, or fiberglass.
8. Backfill
Backfill the area around the pool with dirt to provide support for the pool walls.
9. Landscaping
Optionally, you can add landscaping around the pool to enhance its appearance.
It is important to note that repairing a pool can be a complex and time-consuming process. It is recommended to consult with a pool professional to ensure that the repairs are done properly. They can also help you determine if trash fill with dirt is necessary.
