Pool Coating Product Comparison
There are two principals in overall pool operation:
- Daily Maintenance and Operation
- Long-term Maintenance and Capital Repair
When you consider resurfacing your pool you should ask yourself two important questions:
- Is your automatic pool cleaning system wearing out due to the rough surface on your pool?
- In the long-term, what is the right pool surface for you?
Here are comparisons to help you decide:
| Plaster | Fiberglass | |
|---|---|---|
| Life Expectancy | As plaster wears, it becomes abrasive, blisters and delaminates. Aside from health hazards (abrasions, cut feet, etc.), plaster begins to deteriorate and breakdown in 18 months to 3 years. The overall life expectancy is 3-5 years for standard plaster and 7-10 years for upgraded plaster products. | Life expectancy is 25+ years. No breakdown or abrasions due to roughness. Surface remains a smooth and safe swimming environment. No adverse effects due to heating. |
| Staining | Staining can begin as early as when the pool is initially filled. Repeated draining and Acid Washing deteriorates plaster and fosters roughing of the surface. Heated pools have a great risk of staining. | Excellent resistance to staining due to its non-porous surface. If mineral or metal staining occurs, it is easily removed by applying a metal magnet product to the pool water. |
| Algae | Plaster is porous and an ideal breeding ground for algae. Removal requires special chemicals and/or the draining of your pool. Heated pools have a great potential for algae. Black algae is difficult to stop on plaster surface, due to a deep root system. | Because fiberglass is non-porous, it is most difficult for algae to grow on the surface. The root system cannot penetrate the smooth fiberglass finish. |
| Structural Coating | Plaster is NOT a structural coating. | Fiberglass resurfacing WILL add integrity to your existing structure and provide a flexible water-proof seal. Fiberglass is a must for cracked and/or leaking Gunite pools and bulged or otherwise structurally damaged Fiberglass pools. |
| Chemical Usage | Plaster is a virtual microscopic mountain range which absorbs a huge percentage of chemicals. The surface interacts with your pool chemicals to obtain the correct pH balance. Over time, plaster will become chemically etched, allowing for a greater opportunity for algae growth and staining. | Because the fiberglass surface is non-porous, it will not interact with your pool chemicals. There is not an adverse effect due to heating and fiberglass will not chemically etch when properly maintained. |
| Warranty | Normally a 1, 5 or 10 year Limited Warranty against pool leaking. Pop-offs and delaminating that do not crack open are not considered a failure. Check cracking (crazing) is not considered a failure but a normal occurrence. | 25-Year Limited Warranty against chipping, peeling and cracking provided your pool remain structurally sound and proper water chemistry is maintained. |
| Required Maintenance | Balance chemicals, acid treatment, brush sides and bottom of entire pool daily for two weeks. | Balance chemicals. SWIM. Chemical balancing with written material and basic instruction provided. |
