Pool Resurfacing Made Simple: Your Complete Step-by-Step Guide
Your pool's surface has seen better days. Cracks spider across the plaster, stains resist every cleaning attempt, and the once-smooth finish now feels rough against your skin. If this sounds familiar, it's time to consider pool resurfacing.
Pool resurfacing involves removing the old surface material and applying a fresh new finish to restore your pool's appearance and functionality. While this process requires significant time and investment, it can extend your pool's life by decades and dramatically improve your swimming experience.
This guide walks you through every stage of the pool resurfacing process, from initial preparation to final inspection. Understanding these steps will help you make informed decisions and know what to expect when working with professionals.
Signs Your Pool Needs Resurfacing
Before diving into the resurfacing process, let's identify when your pool actually needs this treatment. Several warning signs indicate it's time for a new surface.
Surface stains that won't disappear despite aggressive cleaning often signal that discoloration has penetrated deep into the material. Similarly, a rough texture that catches on swimwear or scrapes skin suggests the surface has deteriorated beyond simple repairs.
Visible cracks, even small ones, allow water to seep behind the surface material. This creates bigger problems over time, including structural damage and increased chemical consumption. Frequent pH fluctuations can also indicate surface degradation, as worn materials affect water chemistry balance.
Step 1: Draining the Pool
The resurfacing process begins with completely draining your pool. This step requires careful planning, as you'll need to coordinate waste water disposal and account for weather conditions.
Professional contractors typically use submersible pumps to remove water efficiently. The drainage process usually takes 4-8 hours, depending on your pool's size. During this time, contractors will also disconnect any electrical components and remove pool accessories.
Tampa's humid climate means timing is crucial. Pools should never remain empty for extended periods, as groundwater pressure can cause structural damage. Empty pools are also vulnerable to "popping" during heavy rains, where hydrostatic pressure literally pushes the pool out of the ground.
Step 2: Surface Preparation and Removal
Once drained, contractors begin the most labor-intensive phase: removing the existing surface. This process varies significantly depending on your current surface material.
For plaster surfaces, workers use specialized equipment like pneumatic chipping hammers to break away the old material. This creates substantial dust and debris, requiring proper containment and disposal procedures. The goal is to expose the underlying gunite or concrete shell without causing damage.
Tile removal requires different techniques. Contractors often use diamond-blade saws to cut through grout lines, then carefully remove individual tiles. Salvageable tiles can sometimes be cleaned and reused, though most homeowners opt for completely new tile designs.
The preparation phase also includes addressing any structural issues discovered once the old surface is removed. Cracks in the shell must be repaired before applying new material, and any plumbing or electrical work should be completed at this stage.
Step 3: Surface Cleaning and Acid Washing
With the old surface removed, the pool shell undergoes thorough cleaning. This step ensures proper adhesion for the new surface material.
Contractors typically begin with pressure washing to remove loose debris and dust. Next comes acid washing, using muriatic acid solutions to etch the surface and eliminate any remaining residue or stains.
The acid washing process requires extreme care and proper safety equipment. Professionals must neutralize the acid completely before proceeding, as any remaining chemical residue will interfere with the new surface application.
Step 4: Applying the New Surface
The actual resurfacing application depends on your chosen material. Plaster, aggregate, and tile installations each follow different procedures.
Plaster Application
For plaster surfaces, contractors mix the material on-site and apply it using trowels and floats. The application must happen quickly and continuously, as plaster begins setting immediately. Teams typically start at the deep end and work toward the shallow areas, maintaining a consistent thickness throughout.
The smoothing process requires significant skill and experience. Workers must eliminate air bubbles, maintain proper thickness, and achieve a uniform texture before the plaster begins to cure.
Aggregate Finishes
Aggregate surfaces like pebble or quartz finishes involve similar application methods but require additional steps. After applying the base material, contractors wash away excess cement to expose the decorative aggregate. This process, called "start-up," determines the final appearance and texture.
Tile Installation
Tile surfaces require methodical installation, starting with waterproof adhesive application. Contractors must maintain consistent spacing and alignment while ensuring proper adhesion. Grouting follows tile installation, with careful attention to creating watertight seals.
Step 5: Curing and Start-Up
Proper curing is critical for long-lasting results, especially with plaster surfaces. The curing process typically takes 7-10 days, during which the surface develops full strength and durability.
For plaster finishes, the start-up process begins 14-28 days after application. This involves filling the pool, balancing water chemistry, and brushing the surface daily to remove plaster dust. The initial water will appear cloudy and require frequent filtration and chemical adjustments.
Aggregate surfaces require immediate start-up, beginning within 6-8 hours of installation. Contractors use specialized washing techniques to expose the decorative elements while the surface remains workable.
Step 6: Water Chemistry and Final Adjustments
Once the pool is refilled, maintaining proper water chemistry becomes crucial. New plaster surfaces are particularly sensitive to chemical imbalances, which can cause permanent staining or surface degradation.
Initial pH levels will typically run high due to the alkaline nature of fresh plaster. Contractors gradually lower pH using muriatic acid, while carefully monitoring total alkalinity and calcium hardness levels. This balancing process continues for several weeks until the surface fully cures.
Brushing remains essential during this period. Daily brushing removes plaster dust and prevents permanent staining, while promoting proper surface curing.
Choosing the Right Time for Pool Resurfacing in Tampa
Tampa's climate presents unique considerations for pool resurfacing timing. The region's hurricane season (June through November) creates scheduling challenges, as empty pools are vulnerable to storm damage.
Many Tampa homeowners schedule resurfacing during the cooler months (December through March) when pool usage naturally decreases. This timing also avoids the intense summer heat, which can affect material curing and worker safety.
However, Tampa's year-round swimming season means you'll want to minimize downtime regardless of timing. Professional contractors can typically complete most resurfacing projects within 7-14 days, weather permitting.
Making Your Pool Resurfacing Investment Count
Pool resurfacing represents a significant investment that should last 10-15 years with proper maintenance. Understanding the process helps you make informed decisions about materials, contractors, and timing.
Quality workmanship makes the biggest difference in longevity and appearance. Research contractors thoroughly, verify licensing and insurance, and request references from recent projects. The lowest bid often proves most expensive when poor workmanship requires premature replacement.
