Basic Materials and Installation Steps
The materials and installation process play a key role in determining the durability and cost of different pool finishes. Below, we break down the materials and steps involved for each type of finish.
Pebble Finish Components
Pebble finishes are made by blending small, smooth pebbles with binding agents, fade-resistant pigments, and other additives. This combination creates a durable surface with a consistent texture.
Here’s a step-by-step look at the installation process:
- Drain and prepare the pool surface: The pool is emptied, and the surface is cleaned and prepped.
- Inspect and repair the shell: Cracks or imperfections in the pool shell are addressed.
- Apply shotcrete: A layer of shotcrete is added to level the surface.
- Trowel the pebble mixture: The pebble blend is applied and smoothed out.
- Acid wash: This step exposes the pebbles, giving the finish its characteristic look.
- Fill the pool and balance the water chemistry: The pool is refilled, and water chemistry is adjusted to ensure proper curing.
"Hydration is the chemical reaction of hydraulic cement with water that forms new cement compounds, ultimately producing a stone-like mass. Curing is the process or method of providing sufficient moisture for the hydration or maturation process to proceed until the pool’s cementitious interior finish achieves its desired properties." – National Plasterers Council
Plaster Finish Components
Plaster finishes consist of a mix of cement and fine sand applied as a thin coating. White plaster uses white cement, while colored plaster incorporates pigments for visual variety.
The installation process includes these steps:
- Drain and remove the existing surface: The old surface is stripped away.
- Inspect and repair the shell: Any damage to the shell is repaired.
- Apply shotcrete: A leveling layer of shotcrete is added.
- Trowel the plaster mixture: The plaster is applied and smoothed out.
- Fill the pool immediately: The pool is refilled right after the plastering is complete.
- Balance water chemistry: Water chemistry is adjusted to support proper curing.
To ensure durability, the plaster finish requires balanced water chemistry, gentle brushing during the initial weeks, and avoiding manual vacuuming for at least two weeks.
The quality of installation is crucial for the finish’s longevity. For example, with pebble finishes, techniques like acid washing to expose the aggregate are essential for proper adhesion and appearance.
