The Comprehensive Guide on How to Replaster a Pool

Owning a swimming pool can be one of the most enjoyable experiences, providing relaxation, entertainment, and exercise right in your backyard. However, like any other part of your home, pools require maintenance and occasional renovations to keep them in pristine condition. One such essential renovation is the process of replastering a pool.

Why You Should Replaster Your Pool

Over time, the surface of your swimming pool can suffer from various issues including wear and tear, cracks, and discoloration. Plaster is the most common surface finish for pools, and it may degrade due to environmental factors, improper maintenance, or simply because of age. Here are several reasons why you should consider replastering your pool:

  • Improved Aesthetics: A fresh plaster job can revitalize the look of your pool, making it more appealing and inviting.
  • Surface Integrity: Pool plaster protects the underlying structure from damage and leaks, preventing costly repairs down the line.
  • Enhanced Safety: Smooth surfaces reduce the risk of slips and falls, especially for children and pets.
  • Increased Property Value: A well-maintained pool can enhance your property’s overall value, making it more attractive to potential buyers.

Signs That Indicate It's Time to Replaster Your Pool

Before diving into the replastering process, it's crucial to assess whether your pool really needs this level of renovation. Here are some signs you should look for:

  • Cracks and Popups: Visible cracks on the pool surface or sections that have popped up are clear indicators of damage.
  • Rough Texture: If the plaster feels rough to the touch or is causing abrasions, it might be time for a replaster.
  • Staining: Persistent stains that do not respond to cleaning can be an indication that the plaster is worn out.
  • Water Loss: If you notice unexplained water loss, the plaster may be compromised, leading to leaks.

The Importance of Preparation Before Replastering

Proper preparation is crucial for a successful replastering job. Here’s a detailed overview of how to prepare your pool:

Step 1: Draining the Pool

Begin by completely draining your pool. This involves turning off the pool pump and skimming off any debris that might float to the surface. Make sure to follow local regulations regarding wastewater discharge.

Step 2: Inspecting the Surface

After draining, take the time to inspect the pool surface thoroughly. Look for any cracks, chips, or areas where the plaster has pulled away from the walls. Document these areas for repair.

Step 3: Cleaning the Pool

Remove any remaining dirt or debris using pressure washing. This will create a clean surface for the new plaster to adhere to. Pay close attention to corners and edges.

Step 4: Repairing Damages

Fill cracks and daubs with a concrete patch or pool plaster mix. Ensure these areas are smooth and level to create an even surface.

Choosing the Right Plaster for Your Pool

The next step is to choose the appropriate plaster for your pool. Traditional white plaster is common, but alternatives like pebble, quartz, or aggregate finishes are worth exploring:

  • White Plaster: The standard choice, providing a classic look.
  • Pebble Finish: A mixture of pebbles and plaster for a rugged appearance and enhanced durability.
  • Quartz Finish: More durable and aesthetic than traditional plaster, offering varied colors and textures.
  • Aggregate Finish: These contain colored stones for a varied appearance and increased lifespan.

Steps to Replaster a Pool

Now that you’re prepared, here’s a step-by-step process on how to replaster a pool:

Step 1: Mixing the Plaster

Follow the manufacturer’s instructions to mix the plaster or cement appropriately. Ensure you achieve the right consistency, typically a thick, workable paste. Depending on your choice, you might also need additives to enhance the mixture’s properties.

Step 2: Applying the Plaster

Starting at the shallow end, apply the plaster using a trowel or a pool plastering machine. Feather the edges and overlap layers to avoid lines. Maintain a consistent thickness of at least 3/8 inch. Move steadily across the surface to ensure an even application.

Step 3: Finishing the Plaster

Once applied, you’ll need to smooth the plaster. Use a pool trowel or sponge to create a sleek finish. This will make the surface easier to maintain in the long run.

Letting the Plaster Cure

After applying the plaster, let it cure properly. This process can take about 7 to 14 days, depending on the weather conditions. During this time, it’s helpful to keep the surface moist to prevent cracking.

Refilling and Balancing the Water

Once the plaster has fully cured, it’s time to refill your pool. As you do, ensure you:

  • Check Water Chemistry: Test for pH, alkalinity, and chlorine levels to maintain safe swimming conditions.
  • Monitor Water Levels: Ensure the water rises slowly to avoid damage to newly applied plaster.

Maintaining Your Newly Replastered Pool

After all the hard work, it's essential to properly maintain your newly replastered pool:

  • Regular Cleaning: Skim debris and vacuum the pool frequently.
  • Water Chemistry Maintenance: Test and adjust the water chemistry weekly. This helps prolong the life of your plaster.
  • Avoid Harsh Chemicals: Use pool-safe cleaning products to avoid damaging the plaster.
  • Monitor for Damage: Regularly check for any signs of wear or damage and address them immediately.

Conclusion

Understanding how to replaster a pool is crucial for any pool owner wanting to maintain the beauty and functionality of their pool.
