Cultured Marble Sink: Comprehensive GuideWhat is Cultured Marble Sink?Cultured marble is a man-made composite material composed of 75-80% crushed natural marble mixed with 20-25% polyester resin as a binding agent, with added pigments for coloration. The mixture is cast into molds and polished to create sinks with the aesthetic appeal of natural stone but with enhanced durability and uniformity. The surface is typically coated with a gelcoat finish (0.5-1.2mm thick) that provides stain resistance and a glossy appearance.Key Manufacturing Data: The production process involves vibration compaction at 50-100 Hz to eliminate air bubbles, followed by curing at 60-80°C (140-176°F) for 2-4 hours. The resulting material has a density of 2.3-2.5 g/cm³, comparable to natural marble.Characteristics of Cultured Marble Sinks1. DurabilityCultured marble sinks demonstrate exceptional impact resistance, with a flexural strength of 15-25 MPa and compressive strength of 80-100 MPa. The material's Mohs hardness rating of 3-4 makes it resistant to everyday wear while maintaining workability. Laboratory tests show these sinks can withstand thermal shocks up to 120°C (248°F) differential without cracking.2. Non-Porous SurfaceThe gelcoat finish creates a surface with water absorption rate below 0.1%, significantly lower than natural marble's 0.5-1% absorption. This hydrophobic property is achieved through surface tension of 30-35 dynes/cm, preventing liquid penetration that could cause

Cultured marble sinks offer a blend of elegance and durability, combining the beauty of natural marble with the affordability and versatility of man-made materials. However, like any surface, cultured marble requires proper care and maintenance to preserve its appearance and longevity. In this guide, we’ll explore essential tips and best practices for cleaning, maintaining, and protecting your cultured marble sink.Understanding Cultured MarbleBefore diving into care tips, it’s important to understand what cultured marble is. Cultured marble is a man-made product created by blending natural marble dust with polyester resins and pigments. This mixture is molded into various shapes and then coated with a clear gel layer that gives it a glossy, smooth finish. This protective gel coat makes the surface more resistant to stains and damage but also requires specific cleaning techniques to prevent dulling or scratching over time.Routine Cleaning1. Daily Cleaning RoutineUse mild, non-abrasive cleaners: Cultured marble sinks can be easily cleaned using a gentle soap or a mild, non-abrasive cleaner. Simply mix warm water with dish soap, apply it to the sink surface with a soft cloth or sponge, and wipe it clean. Rinse with clean water and dry with a soft towel to avoid water spots.Avoid harsh chemicals: Strong chemicals, such as bleach, ammonia, or acidic cleaners, can damage the protective gel coat and cause discoloration or dullness. Stick to pH-neutral cleaners or specially formula
