Troubleshooting Common Pool Plaster Issues.

Pool plaster is a critical component of any swimming pool, providing a smooth and waterproof surface. Hollow spots in pool plaster can develop issues over time due to various factors like poor maintenance, improper installation, or environmental conditions. A professional pool technician or contractor for severe or persistent pool plaster issues to ensure proper diagnosis and repair. Regular maintenance of the water chemistry and surface condition is necessary to prevent common pool plaster issues and ensure an enjoyable swimming experience. Here are some common pool plaster issues and troubleshooting tips:

  • Stains: Stains on pool plaster can be caused by various factors, such as metals, organic debris, or algae. To troubleshoot stains, try scrubbing the affected area with a pool brush and a stain remover formulated for your specific type of stain. If the stains persist, you may need to shock the pool or use a metal sequestrant to prevent metals from causing further staining.
  • Cracks: Cracks in pool plaster can occur due to settling, ground movement, or improper installation. Spiders crack in pool plaster can often be patched with a pool plaster repair kit, while larger cracks may require professional attention to assess and repair.
  • Etching: Etching occurs when the pH level of the pool water is too low, causing the plaster surface to erode. To troubleshoot etching, test the pH level of the water and adjust it to the recommended range (usually between 7.2 and 7.6). You may also need to add a calcium hardness increase to restore the calcium balance in the water and protect the plaster surface.
  • Scaling: Scaling is the buildup of calcium deposits on the pool plaster surface, often caused by high calcium hardness levels or improper water balance. To troubleshoot scaling, test the calcium hardness level of the water and adjust it to the recommended range. You may also need to brush the affected areas and use a scale remover to dissolve existing deposits.
  • Discoloration: Discoloration of pool plaster can occur due to algae growth, chemical imbalance, or environmental factors. To troubleshoot discoloration, ensure proper circulation and filtration of the pool water, maintain appropriate chemical levels, and regularly brush and vacuum the pool surface to prevent algae growth.
  • Roughness: Over time, pool plaster can become rough due to wear and tear or improper maintenance. To troubleshoot roughness, you can try using a pool plaster smoother or conditioner to restore the smoothness of the surface. In some cases, refinishing or replastering the pool may be necessary to achieve a smooth finish.
  • Delamination: Delamination occurs when the plaster layer separates from the underlying concrete or gunite shell. Pool plaster delamination can be caused by poor bonding during installation, water penetration, or freeze-thaw cycles. If you suspect delamination, it’s best to consult a professional pool contractor to assess the extent of the damage and recommend appropriate repairs.


Navigating the Maze of Pool Plaster Selection.

Navigating the process of pool plaster selection involves considering various factors to ensure you choose the right option for your needs. Here’s a guide to help you navigate the maze of pool plaster selection:

Type of Plaster:

  • White Marble Plaster: This is the most common type of pool plaster, made from white marble aggregate and white Portland cement. It offers a classic look and is relatively affordable.
  • Colored Plaster: Colored plaster is similar to white marble plaster but includes pigments to achieve a range of colors. This can enhance the aesthetic appeal of your pool but may require more maintenance to preserve the color.
  • Quartz Aggregate Plaster: Quartz aggregate plaster contains quartz crystals in addition to marble, giving it a more durable and stain-resistant surface. It also offers a range of colors and textures.
  • Pebble Tec or Pebble Sheen: These are premium finishes that incorporate small pebbles or stones into the plaster, resulting in a textured surface that is highly durable and aesthetically pleasing. They tend to be more expensive, but they offer superior longevity.

Appearance: Consider the aesthetic you want for your pool. Do you prefer a classic white finish, or are you interested in adding color or texture to enhance the visual appeal? Look at samples of different plaster options in person or online to get a better sense of how they will look in your pool.

Durability and Maintenance: Some plaster options, such as quartz aggregate and pebble finishes, are more durable and resistant to staining and etching than traditional white plaster. Consider your maintenance preferences and capabilities. Some finishes may require more frequent brushing and chemical balancing to maintain their appearance.

Cost: Different plaster options vary in cost, with basic white plaster being the most affordable and premium finishes like pebble etc or quartz aggregate being more expensive. Factor in not just the initial cost of installation but also long-term maintenance and durability when evaluating the overall value.

Climate and Environment: Consider your local climate and environmental factors. For example, if you live in an area with hard water or frequent temperature fluctuations, you may want to choose a plaster option that is more resistant to scaling and cracking.

Contractor Experience: Choose a reputable pool plaster contractor with experience installing the type of plaster you’re interested in. They can guide you to the best option for your specific pool and ensure proper installation for optimal durability and appearance.
