A swimming pool is a fantastic investment that provides relaxation, exercise, and enjoyment for years. However, over time, pool surfaces deteriorate due to constant exposure to water, chemicals, weather conditions, and daily wear and tear. This is where replastering and repair come into play, extending the life of your pool and restoring its beauty and functionality.

Replastering is the process of removing the old plaster layer on your pool’s surface and applying a new one, which improves aesthetics, waterproofing, and structural integrity. But before diving into replastering and repair, proper preparation is crucial to ensure the job is done efficiently and yields lasting results. This article walks you through everything you need to know about preparing your pool replastering and repair.

Why Replaster and Repair Your Pool?

The plaster surface is the waterproof layer that keeps the water in and provides a smooth, attractive finish. Over time, plaster can develop cracks, rough patches, discoloration, stains, or even structural damage due to:

• Chemical imbalances causing erosion or scaling.
• UV exposure leading to fading or brittleness.
• Mechanical wear from heavy use or impacts.
• Water leaks undermine the structure.

Ignoring these issues can result in costly damage, leaks, or an unsafe swimming environment. Replastering renews the surface, improves water retention, and enhances the pool’s visual appeal.

Step 1: Assess Your Pool’s Condition

Before starting any Pool Replastering and Repair, conduct a thorough inspection:

Check for cracks and leaks. Small hairline cracks can be repaired, but large cracks may require structural work.

Evaluate surface texture. If the plaster is rough or chalky, it may need resurfacing.

Look for discoloration or stains. These could indicate underlying chemical damage.

Inspect pool equipment and plumbing. Any broken or outdated fixtures should be repaired or replaced before resurfacing.

Measure pool dimensions. Accurate measurements help estimate plaster material requirements.

Consider hiring a professional pool contractor for a detailed evaluation, especially if you suspect structural damage.

Step 2: Drain the Pool Properly

Draining the pool is a critical step for replastering:

Turn off all electrical equipment. This includes pumps, heaters, and lights to avoid damage or hazards.

Use a submersible pump to remove water gradually.

Avoid draining if local regulations prohibit it, or if the water table is high to prevent pool structural damage due to pressure.

Check for leaks once the pool is empty, which is easier to spot without water.

Draining also allows contractors to work on a dry surface, essential for plaster adhesion.

Step 3: Remove Old Plaster and Surface Debris

The existing plaster must be properly removed or roughened for the new plaster to bond:

Sandblasting or acid washing can help remove the old plaster layer or smooth out rough patches.

Mechanical grinding may be necessary for stubborn areas.

Remove loose debris, algae, and dirt thoroughly to avoid contamination.

Ensure the pool surface is clean and dry before proceeding.

This step can be labor-intensive, but it’s vital for achieving a smooth and durable finish.

Step 4: Repair Structural Damage and Plumbing

Any cracks, chips, or leaks must be repaired before replastering:

Fill cracks with hydraulic cement or epoxy fillers. These materials provide strong, waterproof seals.

Patch chipped or broken areas with compatible repair mortar.

Inspect plumbing lines, skimmers, drains, and returns for leaks or blockages.

Replace or repair damaged plumbing components as needed.

Check pool lighting and electrical systems for safety and functionality.

Repairing the foundation and plumbing ensures your pool will hold water and function properly once replastered.

Step 5: Prepare the Surface for Plaster Application

Once repairs are complete, surface preparation involves:

Etching the pool surface with acid to create a rough texture that improves plaster adhesion.

Rinsing the pool thoroughly to remove all acid and debris.

Allowing the surface to dry completely.

Moistening the surface slightly just before plastering to help with curing.

Proper surface preparation ensures the new plaster bonds firmly and lasts longer.

Step 6: Choose the Right Plaster Mix

Pool plaster comes in various types and finishes, each with pros and cons:

Standard white plaster: Affordable and common, but may stain or roughen quickly.

Colored plaster: Adds aesthetic appeal but may require more maintenance.

Quartz or pebble finishes: More durable and resistant to staining and chemicals.

Marble plaster: High-end finish with smooth texture and durability.

Consult your contractor about the best plaster type for your pool’s usage, budget, and climate.

Step 7: Schedule Replastering with a Professional

Pool Replastering and Repair is a skilled job that requires experience and specialized equipment. Hiring a professional pool contractor is strongly recommended because:

They have the tools for mixing and spraying plaster evenly.

They know how to handle timing and curing to avoid cracks.

They understand local codes and safety regulations.

They can identify and solve unexpected problems on-site.

Work with a licensed contractor to schedule the replastering process. The work usually takes a few days, including plaster application and curing.

Step 8: Aftercare and Curing Process

After Pool Replastering and Repair, your pool needs careful aftercare to ensure the plaster cures properly:

Keep the pool empty or partially filled, depending on the plaster type, for 24-72 hours.

Fill the pool slowly to avoid putting stress on the new plaster.

Balance water chemistry carefully to avoid damage during the curing phase.

Avoid swimming for at least 7 days or as advised by your contractor.

Remove plaster dust or debris floating on the water with filters and vacuuming.

Proper curing maximizes the lifespan and appearance of your new plaster surface.

Tips for Long-Term Maintenance

Once your pool is replastered and repaired, follow these tips to prolong its life:

Maintain balanced water chemistry to prevent plaster erosion.

Regularly clean the pool to avoid the buildup of algae and minerals.

Avoid harsh chemicals or abrasive tools on the plaster surface.

Schedule routine inspections to catch early signs of damage.

Address small cracks or stains promptly.

Conclusion

Pool Replastering and Repair is a significant but worthwhile investment to maintain its beauty and functionality. Proper preparation—from draining and surface cleaning to structural repairs—is key to a successful project. Partnering with professionals and following post-plaster care instructions ensures your pool remains a refreshing oasis for years to come.

If you’re considering replastering or repairs, take the time to prepare your pool carefully. This not only protects your investment but also gives you peace of mind knowing your pool will be safe, comfortable, and visually stunning for many swim seasons ahead.
