Zoiaq is an engineered stone made by DuPont comprised of 93% quartz crystal and 7% acrylic resin, colors and binders. The product is manufactured in DuPont's Granirex plant in Thetford Mines, Canada. It is used most often as kitchen countertops but also as walls. Its primary advantage is that unlike natural stone products (marble, granite, limestone, wood), Zodiaq is non-porous and does not require a sealant that must be periodically reapplied. Porous products, like granite, are prone to growing molds and staining. The color of Zodiaq is consistent throughout. DuPont offers a 10 year warranty on the installation, (as well as the product itself) if the job is done by a certified fabricator/installer.
