ecoFINISH is a high-performance polymer powder coating used as a pool surface finish. It’s praised for its smooth texture, chemical resistance, and vibrant color options. But like any surface finish, it’s not perfect—and knowing what can go wrong helps protect your investment.
This guide covers the most common ecoFINISH pool problems, what causes them, and how to fix or prevent them so your pool stays beautiful, durable, and low-maintenance.
1. Blistering or Bubbling of the Finish
Quick Answer: Blisters or bubbles in ecoFINISH typically result from poor surface prep, trapped moisture, or incorrect application temperatures.
What Causes It:
- Moisture in the substrate before coating
- Improperly cured base (concrete or fiberglass)
- Spray gun temperature or distance not calibrated correctly
Fix It:
- Sand down and recoat the affected area using proper heat and technique
- Ensure the base surface is fully cured and dry before recoating
- Use a moisture meter to confirm concrete dryness pre-application
Pro Tip: Always use trained installers with ecoFINISH certification for best results.
2. Color Fading or Uneven Appearance
Quick Answer: Fading or discoloration often occurs due to UV exposure, water chemistry imbalance, or poor-quality pigment bonding during application.
Why It Happens:
- Extended sun exposure in shallow or beach entry areas
- High chlorine, low pH, or overuse of oxidizers
- Application without a consistent thermal bond
Fix It:
- Reapply ecoFINISH in affected areas with uniform passes and optimal temperature
- Balance pH to 7.4–7.6 and maintain chlorine at 1–3 ppm
- Apply a UV-stabilizing clear topcoat (if recommended by installer)
Suggested Product: Use ecoFINISH ColorGuard Sealant to enhance color longevity and UV resistance.
3. Peeling or Flaking of the Coating
Quick Answer: Peeling usually means poor adhesion between the ecoFINISH and the substrate—often due to inadequate surface prep or temperature errors during application.
Causes:
- Grease, dirt, or residue on the surface before application
- Temperature of the substrate not within the required range
- Incorrect powder application rate or poor melt bonding
How to Repair:
- Completely sand or blast off peeling areas
- Properly clean, dry, and preheat the substrate before recoating
- Apply ecoFINISH using a certified hot-flame powder coating system
Maintenance Tip: Rinse pool walls before application and avoid using incompatible base sealers like epoxy or rubber.
4. Rough or Uneven Texture
Quick Answer: ecoFINISH is designed to be smooth, but rough patches can form due to poor spraying technique or surface contamination.
Common Causes:
- Clogged spray nozzles or inconsistent application
- Dust, sand, or grit embedded in the finish during curing
- Poor temperature control during melt-fusion
How to Smooth It Out:
- Lightly sand the area with fine-grit sandpaper (320–400 grit)
- Clean thoroughly and reapply a touch-up spray if needed
- Use proper flame distance and movement during reapplication
Pro Tip: Avoid applying ecoFINISH on windy or dusty days—use a controlled environment whenever possible.
5. Staining or Discoloration
Quick Answer: Stains on ecoFINISH surfaces are typically caused by metals, algae, or imbalanced pool water—especially if water sits stagnant for long periods.
What to Look For:
- Brown or orange stains = iron
- Green/black = copper or algae
- Chalky white = calcium buildup or scale
Fix It:
- Use a metal sequestrant weekly to prevent stains
- Spot-treat with ascorbic acid for metal stains
- Use a non-abrasive scale remover for calcium buildup
Recommended Product: Natural Chemistry StainFree is safe for ecoFINISH and works on most surface stains.
6. Delamination from Fiberglass or Concrete
Quick Answer: Delamination is when the coating lifts entirely off the substrate—often the result of poor bonding or substrate movement.
Why It Occurs:
- Surface wasn’t properly abraded or primed
- Concrete or fiberglass flexing beneath the surface
- Moisture intrusion under the coating
What to Do:
- Remove delaminated sections by sanding or blasting
- Reprime and reinforce substrate as needed
- Reapply ecoFINISH with proper prep and bonding temperature
Installation Tip: ecoFINISH adheres best when the substrate has a light profile or roughened surface (via sandblasting or grinding).
ecoFINISH Pool Troubleshooting Table
| Problem | Cause | Solution |
|---|---|---|
| Blistering | Trapped moisture or incorrect heat | Sand and reapply on dry, preheated surface |
| Color fading | UV exposure or unbalanced water | Use UV-resistant sealant, balance chemistry |
| Peeling | Poor surface prep or adhesion | Strip and recoat using proper heat settings |
| Rough texture | Dust or uneven spraying | Sand, clean, and recoat affected area |
| Stains | Metal, algae, or scale buildup | Treat with sequestrants or ascorbic acid |
Best Practices for Maintaining an ecoFINISH Pool
Weekly:
- Test and balance water chemistry (pH 7.4–7.6, chlorine 1–3 ppm)
- Brush walls with a soft-bristle brush
- Use metal sequestrant and enzyme cleaner
Monthly:
- Inspect for small blisters, chips, or stains
- Polish faded areas using microfiber and a marine-safe wax
Annually:
- Drain and inspect waterline for UV fading or buildup
- Apply ecoFINISH-compatible surface sealant if needed
Conclusion: Keep Your ecoFINISH Pool Looking and Performing Like New
ecoFINISH is one of the most advanced pool surface options available, but like any premium finish, it requires proper installation and regular care. From blistering and fading to rough patches and stains, most issues can be resolved—or avoided altogether—with the right techniques.
Want long-lasting performance? Stick to certified installers, follow maintenance best practices, and use the right tools to treat your surface. When in doubt, consult with an ecoFINISH expert to keep your pool stunning for years to come.
