Solid surface acrylic resin countertops have captured the hearts of homeowners for years. And solid surface sinks are popular for many of the same reasons. These sinks are typically installed as under-mount sinks but may also be integrated directly into the countertop. Another variety of solid surface sinks are drop-in style.
Solid surface acrylic resin sinks and countertops are made by different companies and have various names such as Corian, Wilsonart, Formica, Avonite, Staron, and so on. These acrylic resin materials are not the same as quartz composite materials such as Cambria or Corian Quartz.
The weakness of solid surface is that it loses luster over time and can look dull and dingy due to grime and scratches. Sometimes solid surface tops can crack and need repairing, but most often sinks just look bad. A thorough cleaning with a strong cleaner and, if necessary, sanding with fine sandpaper can help restore an old solid surface sink to its former glory.
