Once any necessary repairs have been made, it’s time to clean the entire surface of your swimming pool meticulously. Begin by removing debris using a wire brush or air compressor to eliminate loose plaster dust particles as well as algae growth. Thoroughly scrubbing with muriatic acid solution (1 part acid diluted with 10 parts water) can effectively remove stubborn stains caused by organic matter or minerals like calcium nodules.
Gathering Necessary Tools and Materials
To successfully execute a proper plaster job on your swimming pool, you will need specific tools and materials readily available beforehand:
List of tools required
- Wire brush
- Air compressor
- Trowel
- Rubber gloves
- Safety goggles
List of materials required
- Muriatic acid
- Bonding agent (specifically designed for use in pools)
- Plaster mix (white portland cement combined with marble dust/quartz sand)
- Water
Applying the Bonding Agent
The bonding agent serves as a crucial layer between the existing pool surface and the new plaster, ensuring proper adhesion. Follow these steps to apply the bonding agent effectively:
-
Mixing the bonding agent: Read and follow manufacturer instructions for mixing ratios of your chosen bonding agent.
-
Applying the bonding agent to the pool surface: Using a trowel, evenly spread a thin coat of bonding agent over every inch of your swimming pool’s interior walls and floor. Make sure there are no missed spots or areas with an excess amount of bond coat.
Mixing and Applying Plaster
Now that you’ve completed prepping your pool and applied a bond coat, it’s time to mix and apply plaster layers to achieve a smooth finish.
Preparing the plaster mix
Follow these steps to create an ideal plaster mix:
- Mix white portland cement with marble dust or quartz sand according to manufacturer instructions.
2 . Gradually add water while stirring continuously until you achieve a thick yet workable consistency.
Applying coats of plaster
To ensure long-lasting results, it is recommended to apply multiple coats (typically two) using specific techniques:
#### Applying first coat
– Start by dampening (but not saturating) each section of your swimming pool with clean water before applying any plaster.
– Using your trowel, apply an even layer (approximately 3/8 inch thick) known as “scratch coat” on all surfaces in one direction.
– Allow this first layer enough curing time before moving on (~24 hours).
Subsequent coats
- Before applying subsequent layers, moisten previously cured scratch coat lightly with water using spray bottle or hose nozzle attachment.
- Apply additional coats at approximately 3/8-inch thickness each following same procedure as previous step: smoothing out surface uniformly while keeping wetness consistent throughout the application.
Smoothing and leveling the plaster surface
To achieve a smooth finish, it’s essential to pay attention to details during this final stage of plastering:
-
Smoothing: Use your trowel or pool brush in circular motions to gently flatten out any imperfections or uneven areas on each coat while it is still wet.
-
Leveling: Check for consistency in thickness across all surfaces using a straightedge or level tool. Make adjustments as necessary to ensure an even layer throughout your swimming pool.
