| FEATURE | ADVANCED-GLASS | PLASTER |
| Materials & Composition | High-performance resins reinforced with glass fibers; smooth, non-porous surface. | Cement-based mixture with aggregates like quartz or pebbles. |
| Durability & Structural Integrity | Superior tensile strength; resists water absorption and chemical corrosion for a longer lifespan. | Lacks structural strength; prone to cracking and surface degradation over time. |
| Resistance to Algae & Stains | Non-porous surface prevents algae attachment and resists staining. | Porous nature can harbor algae and stain over time, especially from metal rebar. |
| Aesthetics & Surface Texture | Retains water clarity and a smooth, comfortable surface for swimmers. | Initially appealing but may degrade with discoloration, mottling, and rough texture. |
| Chemical Usage & Maintenance | Requires fewer chemicals due to its inert surface, making maintenance easier. | Higher chemical demand to prevent surface degradation and balance pH levels. |
| Warranty & Longevity | Longer lifespan with comprehensive warranties due to durable composition. | Warranties often limited; natural wear leads to degradation over time. |
