Quartz composites are also often called engineered stone or quartz surfacing. They are popular for kitchen and bath vanity countertops and can also be used for most interior surfaces including bath surrounds and flooring.
Quartz surfacing has the look and feel of natural stone, but technically is a solid-surfacing material. It is composed of 90 percent quartz and 10 percent acrylic or epoxy binder. And since natural quartz is an extremely hard mineral (only diamond, sapphire and topaz are harder), quartz surfacing provides a very durable, nonporous surface highly resistant to stains, scratches and heat.
