What is Pool Plastering?

Pool plastering involves applying a smooth, durable layer of plaster over the interior surface of a swimming pool. It serves multiple functions:

  • Creates a waterproof barrier
  • Enhances aesthetic appeal
  • Provides a surface that is comfortable to the touch

Importance of Proper Plastering

Proper plastering is essential for the following reasons:

  • Durability: A well-applied plaster coating can last 10-20 years, depending on the materials and maintenance.
  • Safety: Smooth plaster reduces the risk of injury to swimmers.
  • Aesthetic Value: A properly finished surface enhances the overall beauty and relaxation environment of your pool.
  • Water Chemistry Management: Good plaster helps in maintaining balanced water chemistry by minimizing the absorption of water into the substrate.

Materials Used in Plastering

The selection of materials is critical for the success of the pool plastering process. Common materials include:

  • Marcite (Traditional Plaster): A mixture of white cement, marble dust, and water, offering a classic look.
  • Diamond Brite: A brand of plaster that incorporates colored quartz, providing a decorative finish and added strength.
  • Pebble Tec: A unique blend of plaster and small pebbles, known for its durability and natural appearance.

Step-by-Step Pool Plastering Process

Understanding the pool plastering process involves several key steps:

1. Preparation of the Pool Surface

Before beginning the plastering, ensure the pool is clean and all necessary repairs have been made. This typically includes:

  • Draining the pool
  • Removing old plaster, if needed
  • Repairing cracks or structural issues
  • Cleaning the surface thoroughly to remove dirt and debris

2. Applying Bond Coat (if necessary)

In many cases, a bond coat is applied to improve adhesion between the old surface and the new plaster. This is especially important if the pool was previously plastered.

3. Mixing the Plaster

Each material has specific mixing requirements. Typically, you will:

  • Follow the manufacturer's instructions, ensuring the right water-cement ratio.
  • Use a mechanical mixer for thorough blending.
  • Mix in small batches to prevent premature drying.

4. Applying the Plaster

Once mixed, the plaster must be applied quickly. Techniques include:

  • Using a trowel or plastering machine to apply the material evenly.
  • Starting at the deep end and working towards the shallow end.
  • Aiming for a smooth, consistent application, typically 1/2 inch thick.
  • Working in sections to ensure the plaster adheres properly.

5. Finishing the Surface

After application, the surface needs to be finished. This may involve:

  • Smoothing the surface with a trowel or float.
  • Creating texture, if desired, for aesthetic purposes.
  • Paying special attention to corners and angles for a clean finish.

6. Curing the Plaster

Curing is an essential part of the pool plastering process. Follow these steps:

  • Keep the surface damp for a minimum of 5-7 days post-application.
  • Use a garden hose or a spray system to mist the surface regularly.
  • Avoid heavy water loads immediately after plastering to prevent damage.

7. Filling the Pool

Once curing is completed, you can fill the pool with water. It's vital not to fill too quickly, which can create pressure issues.

8. Balancing Water Chemistry

Finally, after filling, it's crucial to balance the water chemistry. This involves:

  • Testing pH, alkalinity, and calcium hardness levels.
  • Adjusting as necessary to ensure safe and healthy swimming conditions.
  • Regularly monitoring the water conditions in the following weeks.

Care After Plastering

To extend the life of your newly plastered pool, consider the following care tips:

  • Regularly clean the pool to prevent staining and buildup.
  • Avoid harsh chemicals that can degrade the plaster over time.
  • Monitor water levels and chemistry closely during the initial weeks after plastering.
  • Consider resurfacing every 5-10 years to maintain aesthetics and functionality.

Conclusion

The pool plastering process is a vital aspect of maintaining and enhancing your pool's beauty and durability. By following the guidelines and steps provided in this article, you can ensure a successful plastering project that will provide a stunning and functional swimming space for years to come.
